"Juddering" during acceleration
Hi guys
I've had a good trawl of the forums before posting this and, whilst there are a few things that sort of match what I'm about to describe, none of them sounds exactly like my problem. I've got a 2010 S40 Drive with start/stop and, for the last couple of months, I've noticed that the car seems to sound like it's struggling under acceleration. There's no actual issue with power - it very rapidly gets up to speed - but the engine judders like it would if you were trying to accelerate in a gear that's too high. The noise doesn't seem to feature too badly when out of the car but it's very noticeable inside. I keep meaning to take it in to the dealer but the reception I got when I took it in for the B pillar rattles (basically, "You're imagining it because we can't hear it") makes me reluctant. Any ideas? |

Reminds me of a faulty engine mount I had on a Mondeo years ago, drove fine but felt terrible.

Sounds to me very much like an EGR symptom. Although I wouldn't expect it on such a new car, maybe if it was alot of short trips and miss daisy driving style perhaps??

I drive 60 motorway miles every day and, given that I use the car on blue light runs 2 or 3 times a week, I suspect Miss Daisy wouldn't enjoy herself...
