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.

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

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

Ok here goes let me know if it worked, I just did this tonighthttp://https://flickr.com/photos/147...57670622956643

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.

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 ***

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. 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.

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

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.

Bad luck mate, no matter how well we "enthusiasts" think we know cars we still get shafted occasionally.

Never mind polishing a turd, I'd be sending one, neatly boxed, to the scumbag who sold it to you!

I've used these before.

Excellent service.

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.

Not without a speedo, I wouldn't have thought

Fair point!

You muppet!!

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) (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.

If you're going to do it deliberately, do it like this...

Funny videos, shows the strength in the airbags

[roryscott30]

So here is a pic of the cem, it looks to me as if there is a relay missing. Where can I get a clear copy of the cem relay layout?

I'll have a look for you after 8, when I'll be at work.

[roryscott30]

Perfect thanks.
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.
