2.2D Sounds Rough When Cold

August 26, 2010

My 56 plate (30K Mile)2.2 D4D is sounding like a bag of spanners (and I think down on power) when its cold. After its been running for a few minutes (less than 5) it seems to get its act together & all is fine. If it was a petrol engine I'd say it was running on 3 cylinders !

Its due a service in the next month & I cleaned the EGR out recently (which was new at the last service). Any clues as to what the issue might be?

Just back from a 1600 mile round trip to France in it again & aside from this its running very well indeed.

These are the same symptoms that ours had. Does it also rattle like hell as you pull away and a little low on MPG??

We took ours in to MrT and they diagnosed faulty injectors. They were then replaced with the up rated, never to go wrong again type. :rolleyes: Fingers crossed.

This is another common problem with the D4D according to the dealer.

All under warranty thank god.

Good luck,

As above, probably "Diesel Knock" you are experiencing. They inject a liitle too much fuel when cold in order to get the engine up to running temp quicker. Try using a quality fuel and see if it helps.

Thanks for that. This is something that has only started in the last week or so - it sounds like a complete bag of spanners when its cold - much worse than it used to. There's still a hint of a rattle when its warm as well I think - or I may just be being paranoid on that one!

95% of the fuel that goes in it is Shell - in fact its got VPower in it at the moment....

Anyway it's booked in for a service next week so we shall see what they say. On which subject,, Shop around! First dealer I rang quoted me £340 for 30K/4yr service & an extra £60 to change the brake fluid. :blink: :blink: :eek:
