T5 problems continue...

Ok and was it an ETM reload or a complete software update... Or are they part of the same thing?

Cheers

It's not a software update or a reload, it's more a reset of the engine ECU . Or a adaption procedure

But before this can be done all fault codes must be removed from the engine then the reset can be done which is easier said than done.

The engine ECU has learnt how to get the emissions correct when there's a worn component it just adjust it self to bring it back into line,so it just needs to be told there is a new component then it just goes back to day one and relearns what it needs to do.

Is this not the same as clearing codes with a code reader and/or leaving the battery disconnected?


Many thanks

No it's not the same as a reset with a code reader,also if you get a brand new unit it will need programmed to the car.

Link for a aftermarket machine. So it's not just a main dealer thing.

Useful info - looks like a trip to the dealers may be in order.

I did call my local dealer last week and they specifically quoted me for an ETM reload so I'm guessing they're not making it up.

I must admit when I was looking at etm issues I always read they need to have a reload, I didn't have mine done but I read and spoke to my local dealer and they said it would be able to limp in but it definitely wouldn't run right and would need to be adapted to the car, same as a lot of newer electronics, (diesel injectors etc) they need to be matched to the car

Fair point.

The only reason I thought it wasn't necessary was because the chap who fitted the new TPS to my existing throttle body said that, due to the fact the internals/electronics of the throttle body are not touched, it will not require any kind of update or coding...

...whether or not this is a load of cobblers, only a visit to the dealers will tell I suppose. Still, £72.00 for an ETM reload, they really know when they have you by the nuts don't they?

[JamesT5]

Right, my turn now. I got after 11pm and was up for work at 4.30am today so this is the first chance I've had to give my verdict.

To me it seemed like a Boost problem, most likely the BCS or similar because the car would boost and then cut out and then boost and cut out. Having pretty much ruled out the ETM as far as I'm concerned, the coil packs, the MAF and the a sensor on the intercooler pipe, it seems there's little left but a Boost issue somewhere which also is creating an erratic idle. It could also be a Lambda or O2 sensor hence our attempts to change the grey sensor over that clips on to the Air Filter housing.

Personally I think we made very good progress yesterday and it was a good effort that has narrowed down the problem by a massive factor, plus it was great to take the hands-on approach to assisting another VPC member with their car and Ed, it was a pleasure to meet you as well! I don't think yesterday was a wasted effort in any way shape or form and I think we should be very proud of our achievements. This sort of thing is what the forum is about, helping others!

Unfortunately, we ran out of time and it was a pity we didn't get more time to go through the car in more detail but having been on a night shift the night before I wasn't able to get there until around 3.30pm. Still we made good use of the time finishing up around 9pm. To be perfectly honest, it felt more like one of Stribo's 'Mini Fix' meets....

Anyway, the cuts and scratches to our hands are no doubt slowly healing and would I be tempted to help out again like this? Of course I would because it's exactly the thing we should all aspire to do if we can and it's practical. It can save us from expensive garage bills and we learn more about our cars all the time. Only when we have exhausted every possibility in the time available like we have done, should we spend money in a garage for something like this. At least that way we know what it isn't and can avoid getting fleeced!

Ed - a good effort all round! By the way, I was convinced it was curry that your family were having but I was obviously 'mis-steak-en'.

In the end I stopped at a Tesco Express in Kidderminster for some food rather than McDonalds as planned as I realised I needed to buy some stuff to take to work today, it seemed the logical choice.

[mike 850]

I completely agree and I am always helping friends with cars etc, I hate paying a garage and would only do so if I had no choice! it is what its all about and good on you, hope you get to the bottom of it!

[jamesy12345]

Good read guys, I agree do what you can yourself...you get a sense of achievement when the car is sorted but can be a real pain in the bum if you can't track a fault down. That's where I would eventually head to a specialist also (dealer would be last option for me).

I don't think it's only dealers who can load the software btw - I once had a conversation with Russ at RT Mechanics about ETMs and I'm sure he said it was possible for RT to adapt new stuff on the car. I've never used them so can't say 'go there', just saying that maybe there is a middle ground here by heading to an independant near you with the right gear.

[V70 Graham]

GRN (specialist who didn't really seem to have a clue

To be honest there are only 4 people I let work on my car, 2 specialist Volvo independents with 30+ years experience each, M-R-P and GRN Motors, Benny has a great deal of knowledge and has never let me down yet.

I have a similar problem on my C70 2.4T (1999 ME7). Im positive it is my repaired ETM, as was ok before repair. The repair fixed my idling/stalling problems and turned the engine light off, but now i have intermitant rough running and hestitation for a few seconds every now and again, maybe twice for a few seconds during a 1 hour drive, but sometimes it wont do it for 500 miles. It started doing this immediately (same day) after i refitted the repaired ETM. I have 5 new quality coil packs, plugs, new Volvo BCS, recent Bosch Maf etc. Annoyingly when i took it to HLM it didnt do it and was ok for a few days after the remap too, no fault codes were showing and hoses and vac pipes were good and it mapped perfectly, so it is very intermitant and is not getting any worse at the moment. If it gets worse i will bite the bullet and buy a new ETM from Volvo and have it programmed to the car, and bin the repaired ETM. I will loose my remap though as when car is plugged in at Volvo it overwrites and updates all software automatically apparently, which is why i will wait until my problem gets worse as very occasional at the moment, and not worth losing my remap for an occasional hesitation and momnetary lack of boost.

A chap at the local Volvo garage where i get my service parts from immediately told me my problem was very likely the ETM or possibly a boost leak from my description as he had exactly the same thing on his V70 and a new ETM fixed his. Also he said that you need to program a new ETM to the car as it wont work properly and will run in limp mode. Secondhand ETM's work ok as if the part number matches your old ETM and was off the same model of car, the programming may be an older or newer software version to what you had before but should work, but chances are the secondhand ETM will probably be off a different car and so might not have exactly the correct software and so run rough also.


I think both your cars could also be ETM related. One of you needs to try a new ETM and reprogramming at a Volvo dealer. Pre 2004 Morelli Magnetti EMTs have 96 percent failure rate within 100K apparently, so it is going to fail at some point..........

[Harvey]

Yes but .............. You still need your codes downloaded with a reader.

[Leeds_finest]

I'm not disputing that.

Had the car produced EML and/or codes I would've been taking it to be read with Volvo software following this weekend (drawing a blank)

However, it has no EML or codes. Having said this, it should flag up any faults when they plug it in for ETM reset.

[jez.w]

I have the contactless repair from Volvo Diagnostic £130. It has 100 percent fixed the idle and stalling and turned the engine light off. But ever since i fitted the repaired ETM i have had this occasional rough running, lack of power, and hesitation which last a few seconds and then goes which was definitely not there before. If i drove gently all the time i wouldnt even notice, as once the car has warmed up it only really plays up when you accelerate quickly, although it is also hard to pull away smoothly sometimes when the engine is cold and revs are low. All I'm saying is the contactless repair itself is probably fine but my ETM is now causing a hestitatation and lumpyness now and again, so there is something else wrong with my ETM or the current software is having a problem with the repaired ETM? I'm 99 percent sure a new ETM and new software will fix mine, although as i said i will not do this until it gets worse as i can live with it at the moment, there are no error codes, and its not that bad. It might never get worse and i can live with it as-is. As i said in the early post, my car can run everyday for a week spot on, then it might run lumpy for a few seconds a couple of time the following week, so it is occasional.

Prehaps we have the same fault? I will watch this thread with interest to see what the outcome is.

Yes you are spot on ,if the car has a small error it will log it but it won't always put the cel on.

That's why is told you how to test for them but your dim is not working.

I agree it does need a live check with VIDA and hopefully they will carry this out at the same time as resetting my throttle module... or do you reckon a further diagnostic check is extra?

Either way they said they need the car for an hour for any diagnostic so hopefully it's a thorough check.

Well I'm glad you've said that as that's the same person I used to repair mine although the running is almost as bad as before.

Mine idles poorly and drives without any poke, it's very flat most of the time.

The Volvo Diagnostic chap claims you don't need to reset anything, but I'm unsure now...

...do you think this could be my fault?

Yes you are spot on ,if the car has a small error it will log it but it won't always put the cel on.

Yes sadly my DIM is out otherwise could've checked the codes bloody car!

No to read all the codes ,as they all will come up when you plug the machine in
Also ask for the printout of the codes handy to keep.
,the but is if they won't clear as there is a proper fault on a Component that is what could cause a problem,
to clear and reset the faults from the car you need to run the engine for 30 secs or so so it can do a self test to see if the fault returns if it does return with a fault ,it won't reset the codes.
It's a bit chicken and egg situation what comes first.

[silverhorse]

All I can say on this subject is..... I am mighty relieved that I don't have the MM module!!

[Leeds_finest]

Whatever it is, it's something ridiculously intermittent.

Just fired it up from cold, smooth at first, then idled a little rough.

Took it round the block and did its usual lumpy running lacking power.

Got it home, let it idle (rough) then gave the engine a little rev then let it idle again and the idle became smooth?
