D2 running issues - advice wanted - Page 10

lcnar01 · Dec 22nd, 2011, 17:08

I'm at the same stage as you Faffi, two goes at loading the new software, and the adaption carry-on, but no positive results. In fact, now that the weather is colder, trying to control the revs in 1st and 2nd gear before the engine warms up is nigh on impossible.
I've been very busy lately, and doing mainly long runs which are not so bad since once the car is up into 3rd its ok, but after the new year I'll have to take it back again to the dealer.
Don't know how this saga will end, but it looks like the S40/V50 is due for the chop soon, I just wish it had happened last year!

Same with mine. It may have some hickups at ultra low rpm in 3rd as well, but they pass immediately. The trouble is 1st and 2nd gear. Have you tried to take off from a standstill without touching the throttle to see if it sometimes raise the revs itself as mine does?

Mine also runs very, very erratic immediately after starting most days, but that passes within 30 seconds or so. After that, temps seems to have no impact. Idling along in 1st and particularly 2nd gear, however, is the pits.

There is some issues with the D2 engine, I have had a few customers ask
me about this. Software will improve the running slightly, however after talking with Volvo technical support team. They are working on a cure for the problems you've been experiencing. As far as I know they are still working on this and have been for a fair while now

TBH it is not the S40/V50 that is the problem, most S40/V50 owners are very happy. It just seems to be this D2 to engine that causes all the problems.

Hope they manage to sort something out soon for you as it sounds like a complete PITA!

I agree - it's the D2 donk, not the car. Without doubt, my car is a lemon in several ways in that I've had several mechanical issues as well, but I do not believe that to be generic for the model or the brand. I still want a Volvo, but I want one that works. I think a petrol engine will be a good start.

This is designed in to help pull away , certainly on the 5 cylinder diesels for the last 2 years , i cant say i have noticed it on the D2 though although havent looked for it on those . The test to see if it is:
do the revs rise in neutral as you lift the clutch pedal UP ( not down ) , rpm will rise a couple of hundred rpm about half pedal travel ????

I'll try that to see, Clan. However, whether it should be like that (which is such an annoying design that I'd like to neuter the bloke who dreamed it up as I am capable of manning the throttle on me own) it should be 100% consistent. On my car, it isn't; most of the time, just after picking it up after a re-programming, it will raise the rpm, but not always. After some time, it will mostly NOT raise the rpm.

The really, really annoying bit is when it decides to chop the rpm once the clutch is home until rpm drops to 800 only to instantly accelerate back to 950 rpm. Or when it thinks I need 2200 rpm instead of 1200 to take off.

faffi · Dec 23rd, 2011, 22:00

Hi, Clan, I tried to test for it using various release speeds of the pedal with the box in neutral, and revs did not climb.

I were thinking that if I could get rid of ESP, ABS, idle speed retainer when in gear, clutch sensor, adaptive programming and whatnot, the car would be a hell of a lot more desireable. Just keep the basic sensors for air pressure and temp, boost, engine temp, rpm and throttle position and junk the rest since it's pretty useless anyway and tend to be sources for faults. Any chance that could be done?

Alas no , and it seems your car isnt fitted with this latest rpm increase trick .
It would be great if volvo made a range of simple cars back to 240 style with a basic engine like a B5254S and no network system or emission equipment , it might even sell .

You seem to be suffereing a lot with your car , the car doesnt seem to be at the dealer though being sorted with the help of their tech department .. I would leave it there for a while until its fixed , Most D2's are 100% ok now .

Perhaps I should ask Volvo to bring you over - few seems to have more knowledge about Volvos along with deductive skills to put them to good use. I think you would have solved my problems, quite honestly!

I'm pretty sure my car is a lemon untypical for the range due to number of faults I have had. I also think that the issues with the erratic running is down to a troubled sensor or similar. Why else would the revs sometimes climb when I let out the clutch, and at other times not? Or I get far more revs than I ask for when taking off? Or the power sometimes dropping right off when the clutch gets fully engage, with or without me operating the throttle, and at other times the transition is utterly smooth? Or the going on and off the throttle sometimes being abrupt, at other times smooth? Or there being severe throttle delay?

It seems like the engine management is confused at times, like it doesn't know whether to assist my throttle foot or not. When it doesn't, it's fine. When it does, it's fine too, although I am a bit annoyed. But when it cannot make up its mind, the car misbehaves in the worst manner. And also, since the really serious issues takes place in 1st and 2nd gear, that are restricted from delivering full power, it does suggest something must be related in some way.

That still doesn't explain the power pulsation in 3rd and 4th gear from time to time - not enough to set the car bouncing or knocking the transmission, but every passenger notice the rapid power variations, like should I pump the throttle. Also, it doesn't explain why the engine dies and runs and dies and runs sometimes when the DPF regenerates.

So maybe I'm barking up the wrong tree.
