    I've got an E83 N47d20 (not sure if it's a or c) that hunts when idling cold. Not massively and it goes when it's warmed up. has anyone experienced anything similar? I've had the EGR diaphragm/pulley off and that's actually pretty clean and moving well.

    Hi guys. Purchased my new car a couple of months ago in the form of a 2010 E90 LCI 330D MSport with 115000 miles on the clock.

    Hi. This is a clip of my 2006 318Ci (N46) starting up cold: It doesn’t make the noise on a warm startup. It also has a tendency to idle fairly rough when cold, but I’m not sure it’s related. No warning lights or anything and the last time I had it read my mechanic didn't mention any codes...

    I’ve had a compact 320td for years, I love it and it’s hardly given me problems since I’ve had it but it has always seemed down on power. The turbo failed, although I replaced it with a brand new one, I think it was the filter, which I replaced with a vortex type. It has always black smoked on...

    Hi, I have a squealing sound when cold and I had this problem with a previous car which was easily fixed by a mechanic adjusting something like a tensioner on the serpentine belt. Can this be done with my e46? Thanks in advance
