T5 problems continue...

No, I haven't failed and nor has Ed, it's work in progress. Just because you haven't had any issues with your car doesn't mean to say the rest of us who try and fix ours on a shoe string budget have failed. If your car had done ultra high miles I guarantee, post 2004 or not, it WILL have had major issues at some point.

So, perhaps the rest of us who are learning something about our cars all the time and showing persistence and backbone should be congratulated. It's not all about how much money you spend on it, it's the effort and the goal at the end that actually matters. Perhaps we want to spend time on our cars like this, did you consider that?

The way it looks to a lot of us is that there's something going on that can't be diagnosed by the average spanner-monkey on his driveway.
You've both had issues when replacing/repairing the ETM and amongst conflicting opinions, the fact that that the ETM might need flashing seems to be becoming more and more prominent. I honestly didn't think this would be the case but looking at what's been recently posted, and remembering that the P2 ME7 is more complicated than the P1 (P2 is actually ME7.1 iirc) The "plug 'n' play" idea could very well only apply to the P1.

Have either of you phoned somewhere like MRG or HLM etc ? you might get a simple yes or no and possibly solve both your problems. Or at least, rule out the ETM being the problem.

You say there are no codes listed.

Try the cars own display and see what it say back.

1 turn key to on (lights on the dash on)
2 press read button on l/h arm and hold on
3 press rear fog lamp switch button 3 times quite fast then the left hand dim display will say if there are codes in the car.
4 let go of the read button .
5 press the read button to go thought the list of control boxes one at a time.

Take a pen and paper as they can log a lot of faults most are not important .

Sadly my left hand display has failed thanks for the suggestion though.

Why pay out for garage labour when a friends and fellow drivers can lend a hand for diddley squit! Garages should be a last resort IMO.

I agree.

Look guys, I don't have bags of money to fix the car so as James said a garage at £30/40/50 per hour PLUS VAT is a last resort. I have basic tools, a basic knowledge of mechanics and two healthy hands/arms... so i'd rather have a go myself and save myself some money and feel that sense of achievement IF I were to manage to fix it myself.

I paid £1,400 for my car and I bought it as a cheap (meant to be reliable) run around until I could afford something nicer/better. I'm trying to avoid spending a lot of money as I spent thousands on my S60R and lost every penny when the value dropped out of them. Yes, I understand, that's cars for you, but I am trying to keep my cheap car running without the expense. If I had a lot of money in the first place, I wouldn't have bought a sub £2,000 Volvo would I?

I spoke to my local specialist who said, yes, you need to go to the dealer and have an ETM reload. Whilst I haven't got a problem with this, I would rather rule out every other possibility first.



...but back onto the tech issue at hand - the symptoms are as such:

Fire up from freezing cold and comes onto auto choke fine, singing on five cylinders.

Drops down to idle and seems to still be on all five.

If left for 5-10 minutes idling it will start to misfire (or so it seems with lumpy idle and exhaust almost making a slight pop noise). At least it has stopped cutting out, or so it seems, maybe the ETM fix did help?

When revved, sometimes the revs will fly right upto 4/5/6k as you want them to. Other times it will limit at around 2.5/3k as though something is wrong with the throttle?

Also, sometimes even holding your foot constant on full or part throttle, the revs will fluctuate even though you asre holding the pedal constant.


Ok, so it all sounds throttle related, but where does that random misfire come in? Idles fine on cold startup then seems to misfire and IF it is a misfire why does it not register and throw a light up like it did when my coilpack was dead?




Thanks

What about the throttle pedal sensor? they can have similar effects to the etm but rarely fail.

The thing with the throttle body, the way I've read it, is that it's not the butterfly misbehaving but the sensor that tells the ecu where the butterfly is. if the readings from the sensor go crazy or blank, the ecu will attempt to adjust the butterfly position, fueling and timing to suit. The ecu responds much faster than the throttle ever could, so it could potentially lead to the injectors massively overfueling (fuel delivery and pressure are also controlled "on demand")

Potentially, a problem that the pedal could cause too but very rare.

There's also the possibility of the wiring to the coil packs degrading and arking, once the engine is hot.

Pedal sensor, coil packs.....are you sure it's not worth a £40 diagnostic to find out once and for all ?

[M-R-P]

Exactly my point.

[graemewelch]

when i had running issues with mine i took it to a local garage to be diagnosed. came up wth loads of fault codes. i bought a fuel pressure sensor as advised and it made no difference, £70 down the drain. plus £40 dianostic. so £110 wasted. next step was a trip to hlm who identified the fault in under a minute. instaled a standard map on to ecu, job done. turned out my ppc unit had gone hay wire and only instaled half of the new file. my point is youve just spent money on a refurbed etm, new plugs fuel filter etc, while these parts havnt cost a fortune it would of payed for a dianostic on dice and youd prob know your problem. and have some change. instead youve had these issues for months and for sake of penny pinching a few quid you could of had 6 months enjoyable motoring. please dont take my comments personaly as james has. modern cars are complicated things these days. best of luck which ever way you go though.

Agreed it is the TPS so the butterfly will open and the TPS will give false readings to the ECU - that should now be fixed and the ETM has been tested before it was returned to me.

As for pedal sensor, quite possibly, again wouldn't it throw an EML?

Exactly my point.

My main gripe with paying a dealer to diagnose a fault is that VIDA will surely read a code as any OBD2 reader will, which, once googled, should return some description or explanation of what's wrong.

If it really does have more detail and depth than a generic reader then yes I would agree it is worth a go.

Well I had only paid £10 for a fuel filter and my justification for the ETM was because they are prone to failure so I was trying to get one step ahead but I do take your point and it wouldn't hurt to have it diagnosed...

...you just hear the 'horror' stories of "I spent hundreds on parts because that's what diagnostic said was wrong - but it didn't fix my fault"

^^ just didn't want that to happen that's all.

if you do go down the dianostic route then id strongly advice you get it done from a place that uses volvo software. this dosnt mean a dealer. they are small specialist dotted about everywear. i got mine done using generic software and the advise and knolodge of volvos was terrible. many volvo specialist have told me only use volvo software and it wasnt to make a extra few quid as he never charged me for to read codes as it didnt fix my issue but he did give me some advise and he was right

When you see Vida/dice at work at a dealer it gives a hole lot more info than a £25 code reader.

It can give you a live scan of all the engine sensors.you could have a engine temp sensor fault that's why it's runs ok when it's cold but when it's warm .
the ecu will try to adjust the running settings to lower the emissions so it also could be a sensor in the down pipe,cat.

You do say that the dim is starting to fail this can also cause running faults.

It's could be anything that's why you need it looked at with a proper code reader.

[M-R-P]

As above, a code reader will only pick up the OBD codes that it would find on most cars (hence the term Generic) There's so much more going on in a P2 that it'll never find.

Although - with the DIM failure, the only "running" issue I had was the cruise control would stop working, throw a "clutch position sensor" fault and only work when I cleared the code. This is normally attributed to the clutch master leaking and ruining the pedal sensor but the fault hasn't reappeared since I changed the DIM. I had no engine trouble caused by the DIM failing and it failed about as spectacularly as it could lol.

[mr shifter]

Personally i would bite the bullet and have a live scan done. You can be faffing around with it for months, changing bits here and there, which could be unecessary and could possibly cost you more than having the scan and repairs done in the 1st place.

[Leeds_finest]

Ok guys,

I take your point onboard.

James is going to help me this weekend have a look over the car and we are going to just rule a few things out - plugs/coils etc which can't possibly hurt can it?

Following this, if I am non the wiser I will try and get it to somewhere with Volvo software.

Are HLM good? I am about 20-30 miles from there. I am closer to GRN I suppose. In all honesty I am unsure it will make it to the bottom of my road in current running condition. May need towing there OR someone mobile with VIDA. Any suggestions?

Thanks

[graemewelch]

ill say two thing. knolodge in wrong hands in dangerous. hlm will get to the bottom of it.

[Leeds_finest]

"knowledge in wrong hands in dangerous."

Considering I recently melted a piston (not in my Volvo) I would totally agree with you, can't be too careful.

[JamesT5]

HLM will get to the bottom of it at some cost. I'm offering my help at no cost and Ed and I won't do anything we're not 150% sure on I'll say that now. Not everybody wants to throw cash down the drain paying a garage when the problem could be fixed on the driveway by two owner-drivers with some common sense.

That and Tim Williams are my recommendations. My DiCE has paid for itself many times over and I haven't §§§§ed anything up badly enough that Tim can't fix it. DiCE will log codes in all modules and live log all sensors. I would never be without it and you are §§§§ing in the wind without proper diagnostic kit on OBD2 vehicles. Good luck with it whatever you choose to do - I won't offer advice on this specific issue as without some datalogging/codes any suggestion is speculation at best.

[JamesT5]

So if Ed and I actually find the fault on Saturday then I can see this thread going very quiet and a few people here walking about the forum with egg on their face. We'll see what we find on Saturday!

All I will say if you get It running is GREAT & WELL DONE

Yes Harvey, from you I don't doubt that for a minute but it just seems some people here think that paying out for a VIDA session is the only option and it's the magic solution. Personally I think it should be used as a last resort after all the other options have been exhausted. I also feel like some comments to this thread are people wishing failure on others who are offering practical help to fellow members, I'm not saying that's peoples intentions but this is how it comes across.

Anyway, I look forward to Saturday!
