Hi all,
Model: 2005, 320d, e90.
I notice lately at around 1500 revs (while driving around 20 mph) in 1st or 2nd gear the car chugs or hesitates (misfires?). No engine management lights come on or anything.
I notice it in particular while in heavy traffic on Corks ring road. If I take the acceleration up in a slow constant fashion, she seems to chug like i am hitting the gas on and off.
Sometimes, when I try to replicate it, it doesn't happen. Also, if I put the shoe down, for example she will fly by the 1500 rev mark and no hesitation.
Just wondering if its a fuel filter, turbo, cat converter, MAF, faulty accelerator problem etc. (or maybe the swirl flaps? heard these give problems)
It could also be happening at approx 1500 revs for higher gears, but I guess, it would feel more subtle.
She's not pushing out black plums of smoke or anything, and she has lots of power, so its probably not the turbo. Note, I have also changed the turbo breather about 10000 mikes ago. I service her with the recommended Castrol oil approx every 8000 miles even though I believe thats too early.
I will try change the fuel filter this weekend. I put some diesel treatment into a full tank to clean the injectors. But that didn't make any different.
any ideas, comments are greatly welcomed.
Will.
