Help

[roryscott30]

Afternoon all,

after a break away from Volvo's I have returned to the fold and just this weekend bought a 2001 V70 T5 manual with a claimed 79k miles on the clock. I collected this from Birmingham from a questionable gent and contrary to the ad description there were many faults. As I had already paid for flight down and the prospect of paying for another returning straight away seemed expensive, I made a new deal and took a chance.
So issues at the moment;

The dash has no life other than the engine management light - seller claimed a new dash had been sourced and tried however, had forgotten which was the original with the car. I tried changing the supplied dash and no difference. Worth noting one of the dashes has a "Volvo diagnostic" sticker suggesting it has been looked at previously.

The engine is clearly in limp mode with no signs of turbo and appears to be suffering from the ETM fault ie hunts at idle, falters when you apply the throttle before levelling out at higher revs. Disconnecting the MAF makes the idle far worse however makes the car run much better during accelerating however still no noticeable turbo kick.

Looked at the CEM last night which was hanging above pedals to discover it also has a Volvo diagnostic sticker so put it back in its hangar - no difference.

Not sure if you can add/replace components using VIDA on a computer or it has to go to main dealers!!!!!! Is there an independent Volvo guy locally?

Seller also supplied a spare accelerator pedal which I connected and still no change.

Connected the car to a friends VIDA diagnostics which gave some more information. The mileage shown on the information reads 168,000 however is this from the DIM or is this in fact from the car? (hope the former)

The DTC's suggest no communication with the DIM and I believe the ETM is also mentioned however as this is my first time using the VIDA diagnostic I am not clear on the information present and what needs to be done next. During the diagnostic session some of the dash info flashes up however disappears again.

Is there someone in the Aberdeen area willing to help me as I am looking to use this car for commuting in a month and money needs to be spent wisely whilst I move house. Really reaching out to the forum for help and yes would probably have been better paying for a return flight but the car has cleaned up well suggesting maybe you can polish a t*rd!

Thanks to anyone for advice/help

If there's a difference between the dim mileage and the cem mileage, the car will show the higher of the two.

Sounds like you should've got back on the plane mate, you bought a dog.

You are absolutely right, just spoke with the incredibly helpful fella from Volvo diagnostic and the plot thickens....

He knows the car, apparently it had been flooded and he had started fixing parts as the owner sent them however they were never the issue!!!!!!!!!! He recommended disconnecting each module to find out which one has a short so I'll start that tonight.
At least it has a MOT (god knows how) so I can keep using it while it is complete.

[kmb]

If you check the reg number HERE (https://www.gov.uk/check-mot-history) it might help with mileage history...

[htomi]

If the car was flooded, there is good chance you going to face with an endless saga here.......

[roryscott30]

Yes the future looks bleak however until I need to spend money I'll try systematically removing parts until hopefully something shows up.

I hope you didn't pay top dollar for it. Fingers crossed you get it sorted mate. I have been in the same position and been burned and it isn't a nice feeling. Now that I'm older and wiser I have learned to walk away even if it means a lengthy journey home and extra cash. It may be worth the journey back to the sellers place just to £££££ in his letterbox though??

[BigGreg]

Must have been a long ride home in Limp mode! Sorry bud, we have all had a dog in the past but this sounds like a howler.

[roryscott30]

I would say it was a slow journey up the road however I have no idea the Acyusl speed I was going however it used £40 from Birmingham to Glasgow which I thought was ok, probably no turbo made the difference ��

It's such a pain everything works electrically apart from the dash and the throttle (key items I appreciate). I took all the modules apart and no difference and connecting the car to vida and examining each item stimulates the dash so I will push my luck once more and phone Volvo diagnostic tomorrow for any other ideas

[htomi]

Lukasz (volvodiagnostic) is a very helpful fella. Best of luck with the car.

[jdavis]

Good luck in getting it sorted. Sounds like you've got a lot of work on your hands.

[Gold 'N' Brown]

however it used £40 from Birmingham to Glasgow which I thought was ok, probably no turbo made the difference ��


That IS good (every cloud and all that :partysmil). I just drove from Edinburgh to Sheffield and back over Mon/Tues and used slightly more petrol than that, and it's a slightly shorter journey. I worked out my actual (brim to brim method) MPG was 29 point something. I also don't have much boost at the moment as my intake temp sensor wiring has snapped at the plug so I believe the ECM limits boost and ignition advance in this state.

May I be the first vulture and say I might be interested in some bits if this ends up a breaker? :tombstone

Oh dear indeed!

No comms between CEM and DIM = exactly that! NO COMMS. So you'll be looking at bad earths (cheapest fix), Relays and fuses (cheaper still as no labour).
Then you're into serious money.

New DIM if yours is goosed is about £900 including software to make it talk to the car.

It is unlikely to be a faulty CEM as VIDA would not communicate with any part of the car at all as all modules link to the CEM at some point, even if via another module.
However, it IS possible to get water ingress on the CEM and it corrodes the pins where the CEM is plugged into the car. On early cars 2000>2003, it was a known problem for water ingress into the CEM via the CEM trunking. It was modified by fitting a rubber boot somewhere on the cable and a kink placed into the harness to prevent water tracking to the CEM. If moving the CEM prompts lights and life in the DIM then you more likely have a bad/corred connection. If it's the pins on the CEM that are corroded (there are hundreds of pins) then your looking at over £1000 for a new CEM from Volvo and it will need a full CEM reload costing another £60-100 depending how much labour to load the software.

It sounds to me like someone has tried to remove the DIM and/or CEM to 'clock' the mileage. As Martin says, it's stored in both the DIM and CEM.

If you want a one stop shop and a relatively quick fix then your only option is the main dealer. However, I wouldn't expect any change out of £3000 if they have to replace them both :eye-poppi

My advice is this:

1). Phone trading standards and enquire about the seller advising them as to what has happened and follow their advice.
2). Limp car back to seller and request an full refund advising that you have contacted Trading standards and that they will/might be in contact, depending on the sellers next move!!
3). Learn from this MASSIVE mistake and don't do it again. :wink:

4) If you don't do any of the above, then sell it for parts cos you're in for a world of pain and a very light wallet!

Best of luck!

[htomi]

CEM modules can be fixed, either by volvodiagnostic or xemodex unless the CEM has the CEM-1D08 or CEM-E000 codes stored or if the CEM lost immobilizer codes then no other way, he need to purchase virgin CEM from Volvo.
Price is steep over €8xx with the service together goes over 1000.

DIM is more less the same game.

Also as mentioned above, if the car was flooded, there is very-very good chance its a never ending story even if the owner willing throw additional money into this pit.

I'm no expert in the UK law, so please feel free to correct me, but here in Ireland, if the car was 'sold as seen', then only the sellers goodwill can save the situation. General forums are full with similar non-happy end tales.

Well I took a chance and bought a new Bosch maf, car is transformed pulls really well so that's given some hope and renewed the fight to fix it. Everything else electrically works it's just the dash now so I'm going to look at possible bad connections next.
The car is booked in to an auto electrician here next week if I can't progress before then.

I contacted the seller and he is sure the car has never been flooded so maybe that was a mistake, having taken the door cards off there is certainly no damage to them but I'll never really know.

Thanks for all messages, I'll keep you posted

[Gold 'N' Brown]

To check for flooding I'd try and pull the main carpet up somewhere and check the sound deadening underneath. I don't know what it''s like on these but I'd assume the proofing is the sort of material that would become water logged and remain wet due to the carpet on top trapping water.

[Redbrick]

A slightly predictable response! ;)

Lucky punt and a good result. How much? £260?? or did you buy a cheaper, non Bosch unit?

Anyway, seeing as you clearly have access to VIDA, is there anyway you can get good, clear photos of VIDA when connected to the car and post up the shots here?
Need to see all the fault codes and would be good to see which modules are affected.

Also, when you last plugged in VIDA, did your friend clear the fault codes to freshen the list? Now you've replaced the MAF, some of the MAF related faults should disappear. I have a feeling the list of codes was very long?

[htomi]

I contacted the seller and he is sure the car has never been flooded so maybe that was a mistake, having taken the door cards off there is certainly no damage to them but I'll never really know.
To be sure, try to check under the carpet (multiple places) and look for signs of water.

So if it wasn't flooded, then it seems the CEM got water damaged due to the issue mentioned by Lee.
Based on your initial post, the CEM has a volvodiag sticker. So this means the CEM either has been replaced or repaired by Lukasz.

As for the DIM:

The dash has no life other than the engine management light - seller claimed a new dash had been sourced and tried however, had forgotten which was the original with the car. I tried changing the supplied dash and no difference. Worth noting one of the dashes has a "Volvo diagnostic" sticker suggesting it has been looked at previously.

I would bring the car to volvodiagnostic and restore the communication between the CEM and DIM first and see the rest from there.
As you guys have VIDA, perhaps it is possible to do via a remote session (TeamViewer) or at least identify where the problem lies without driving the car.

I would strongly recommend to do the diagnostic by a Volvo specialist.

[roryscott30]

Maybe if I could upload the results of a scan someone might be able to spot where the problem lies, any help would be much appreciated.
I think I will book some time with the Volvo dealer next week as suggested above

Thanks again

[htomi]

Take a screenshot and upload onto Dropbox or Flickr or Google drive or any other place where it can be shared online, then post the url into this forum.

You'd be very wise to do so. At least pay for 1 hours diagnostics to try and get to the bottom of the actual fault/s and get a good idea of where to go from there and costs etc, etc.

Would be £75 well spent in my book :wink:

[roryscott30]

No communication between the CEM and DIM (CEM-1A56) also the CEM-1A5F indicates that something is wrong with the CEM itself.

I'm afraid the dealer will suggest to you to get a new virgin CEM unit and get it re-programmed by them. Based on the car VIN number, the dealer can load the original software onto the new CEM unit.
You should expect a min £1000 bill for this only.

As mentioned multiple times, get back to volvodiagnostic and ask what has been exactly done with the CEM.
Ask specifically if the unit has been 1. only repaired or 2. replaced.
Ask what options you have in terms of warranty in both cases.

[LeeT5]

1. CCM-0021 Air quality sensor, internal fault This sensor can be replaced. It lives in the interior fan tract under the n/s scuttle cover. #31250491 £173.40 inc vat

2. CEM-1A56 Communication with DIM control module signal missing **

3. CEM-1A5F Communication with ABS control module signal missing **

4. SRS-00D5 SRS lamp communication fault

5. UEM-0004 Siren Communication fault This is a common fault. You need to replace the alarm module under the drivers side inner wing. #9452709 £166.20 inc vat.

6. CCM-0003 Fan motor passenger compartment temperature sensor faulty signal Look at the CCM front panel and look closely at the small slotted grille on left side. There is a tiny white temp sensor here. Are the slots broken? If not, spray contact cleaner into the slots to clean the sensor. Do not touch with fingers or poke it!

7. DDM-E003 Configuration fault, faulty configuration Drivers Door Module

8. ECM-261A Long term fuel trim, bank 1 - upper limit This is most definitely 100% an air leak! Look for split hoses, vacuum lines or will need further investigation.

9. ECM-510F Vehicle speed signal (VSS) - signal missing

10. UEM-E003 Configuration fault, faulty configuration

11. CEM-1A5C Communication with UEM control module signal missing **

12. DDM-004A Outside temperature sensor signal too high Will require a new temp sensor, base of drivers door mirror??

13. DIM-0001 mileage manipulated Self explanatory :frown: ***

14. DIM-E001 Control module communication, faulty communication **

15. DIM-E002 Configuration fault, faulty configuration.


** These faults could have been caused by disconnecting the CEM or DIM without first, disconnecting the battery and then leaving the car for 30 minutes! Some modules store residual power within, that takes time to dissipate.

Looking at this list, my first conclusion is that it's not the end of the world. :rolleyes: However, that's not to say that your in for an easy ride.

Some of these faults could take 10 mins or 10 hours to fix. Some will cost a little bit of money but the deciding factor is whether any water damage has occurred and if so, to what extent?
Like I said, the worse case scenario is a new CEM and DIM plus software reload at £40 per software.

The CEM is quite a pig to get to and extreme care must be taken when reconnecting the plugs. Any damage to any of the tiny pins could result in communication faults and it's clear to us all, that both the DIM and CEM have been removed at some point. Question is by who and why?? Hopefully, not the dick that sold you the car, cos he clearly doesn't know the first thing about mechanics or proper vehicle maintenance. I've experienced this myself where the car salesman spends the morning being a 'keyboard mechanic' and then tries to fix a dead car himself, without having a clue what he's doing and in most cases doing more damage and making the car store more fault codes.

Rory, It looks like you've already cleared the DTC's in the last picture?

You'll need to do a few drive cycles and turn everything on and off before you'll know if any or all of the faults return.

I think you be best placed to drop this to a dealer or Volvo independant.

*** I think this is the reason why the CEM and DIM have been removed! The CEM not being refitted correctly and possible damage done in the process.

[roryscott30]

Guys that is great thanks so much for taking the time to have a look through the info.

So it may be me that has created some of these faults as I have removed the dim with the original that came with the car in the boot. I never disconnected the battery and yesterday I disconnected the drivers module when I took the door card off.

Having lifted up the carpets it really does not look like there has been in water as it is all very dry and clean under there.

When I spoke with volvodiagnostics he mentioned that both the dim and cem had been bench checked ok and he was convinced it was s "short" in the canbus suggesting checking connection and modules in the first instance. I will get back in touch with him and see what was done.

When I go to the communication section of Vida and add the dim to the list all the dash comes on, I'll add the video to Flickr.



I will book it in to Volvo next week.

This morning after having cleared the codes last night it really is driving like it should with turbo coming in very strong now so I'm really keen to fix this whatever pain it takes. I'm under no illusion this was a dodgy mot but it does let me use it for the 4 miles to and from the house to work. If the wife knew how bad it is, let's just say she is a Latin with a temper and not frightened to use it ;)

Thanks again guys much appreciated

[roryscott30]

Ok so Flickr doesn't like videos but I have attached a screen shot of the dash working. Basically the complete dash is switched on just none of the instruments work however when you add in enginee speed, temp etc in real time they are showing values.

Although I can totally relate to and empathise with your situation, would it not be sensible to get a fresh MOT done so that at least you know the car is safe? It may throw up mechanical maladies that also need money spent on, which might be your tipping point. If not a fresh MOT, maybe a pre-MOT check.

You muppet!! :nutkick:

Rory, you've just learned, the hard way, your first valuable lesson in what NOT to do with a car that has CANbus. You can't just go disconnecting/reconnecting the battery, willy nilly.

You must also remember that before you reconnect the battery, the Ignition switch must be in pos.2. If you don't, you risk firing the airbags off in your face when you do get in the car and switch it on! (just make sure your camera is rolling so we can all have a good laugh at your expense) :hilarious (make sure sound is on as the timing is epic)

Trust me, that would ruin your day and write off the car in less than 1/2 a second if that happens.

It's in black and white in Autodata.

I am going to follow the diagnostic flow chart on the xemodex site, it may give an idea of something obvious before it goes in to Volvo.

[roryscott30]

Well guys just an update.

On a hunch i sent both Dim's to BBA Reman and they discovered both had the same problem which couldnt be fixed so i sourced a t5 being broken on ebay and after checking the serial numbers matched i bought it fir £45 delivered.

It arrived today and.................i have a fully working set of instruments, even cruise control is back.

Yessssssssssssss

[M-R-P]

Result!

I can honestly say, I've never heard of that working at all, nevermind being able to just swap p2 modules and have it all work!

I'm gonna go have a beer and dedicate it to your success

:beer:

[roryscott30]

Thanks I think I'll do the same.

Next is trying to sort the sunroof, from the same car they sent me the working siren at £10 so let's see if that works. It worked for a bit but then failed in the tilt position so I had to manually close it.

Also got to fix front abs sensor, do anyone know where the best place to buy one? ECP has them for £40 ish

[Gold 'N' Brown]

Full respect to you. I think it's very commendable that you stuck with what looked like an absolute nightmare and got it sorted <relatively> cheaply.

[roryscott30]

Thank you, I just didn't want to be beaten by it. It's been a real boost tonight seeing the working dash and keen to get it back to full health

[htomi]

Well done! :worship:

[darzmat]

Just read through this, well done bet you are delighted.

Its this sort of thing cem's and dims that scared me away from the phase 2 motors.

Think I'm gonna stick with my 850

[roryscott30]

Evening,

Siren fitted - sunroof working.

Final gremlin to sort, abs light and traction control comes on when car is warm meaning speedo drops off, 90% sure that the abs module is suspect so will try a replacement or have BBA reman check it over.
Other than that I'm delighted, we are moving house this weekend and I am amazed at how much space these cars have with the seats down, really are all rounders
