Engine: D5: - D5 stuttering and smoking at low revs

V70 D5 · Jun 27th, 2007, 22:23

My 2002 V70 has started stuttering and smoking at low revs- 1500-2000 rpm. It's ok in other ranges and pulls fine otherwise.

Likely suspects are:

EGR valve, MAF or air entry via intercooler or hose.

I followed the advice in the cleaning plenum thread and while there was gunk in the EGR/ plenum hose it didn't look too bad- though I guess the valve itself could be the problem.

Has anyone else experienced this? Could it be something else?

Is there any way to pinpoint the cause without replacing all of the above parts?

Many Thanks

hey mate,

I have recently had this problem with my S60 D5!

Turned out it is a split intercooler!

If you get somebody to rev the car, put your hand over the lower opening in the middle of the front bumper, I could feel air pushing out of mine, and if you check underneath there may be signs of oil leakage like I found.

Also I would check the intercooler hoses and the turbo boost solenoid on the front of the airbox!

Thanks- that's really helpful- I do have oil where you describe though I had thought it was from where the intercooler hose came off around a year ago. The hose looks ok now so it's looking like the intercooler is a likely culprit. I'll have a proper look when the weather's better.

Did you replace you intercooler- I hear they're quite pricey- any tips on sourcing one? I guess it may be repairable with that metal weld stuff in a tube.

Maindealer is cheapest at £190...labours going to hurt abit as was in my case..roughly around the £400 mark should be total cost at indy...

yep from the symptoms decsribed, my s60 dse 53 started having the 'blowing fire' as my other half would say syndrome about a month ago..well service wasnt due so drove around fro 1500 and today
an Indy Volvo specialist has suuplied at £195 and plus cpl hours labour + Vat..cured it by replacing the intercooler.
Funny thing is I drive of..they lock up and half mile down the road the coolant level low ind comes up!
well bonnet wasnt shut and coolant cap off.

coolant below min! BUYER BEWARE!!!
