    BMW 3 Series Forum - Technical Talk on the BMW E46
    Hi All I posted recently about black smoke, loss of power, and INPA selective mass adjustment showing cylinders 5&6 over fuelling - I suspected a valve problem. Not so sure about that now. I did a compression test on a cold engine, but unfortunately snapped the no.4 glow plug. No problem...
  4. Can I test an N42 Eccentric Shaft sensor ?

    BMW 3 Series Forum - Technical Talk on the BMW E46
    Hi all My engine, on low revs, sounds like a diesel, that's possibly the best description of it. It runs perfectly other than this. The engine has about 120k on the clock. My gut feeling is that this part has worn down / oil has seaped inside it. Given past experience, when it comes to...

    Hi All, I just wanted some insight about some issues I had with my x-drive system. One day it went nuts and started jumping on its wheels when in tight turns and I got the trifecta of warning lights. I replaced the nylon wheel on the transferbox actuator and did a fluid change which resolved...

Not worth bothering with or could this be a useful bargaining point and a simple fix? I'm assuming it could be tyre alignment / steering pump /...
