Hi, Wonder if anyone can help!
My wife has a 2003 325 M, until 1 month ago absolutely no problems at all, then: One day after taking the little one out for a drive / sleep the car wouldn't start, no starter motor whirring nothing, but all the lights on the dash lit up, I thought an immobiliser problem. So a mechanic friend of mine took it to his garage and started trouble shooting, he looked into everything (forgive me I'm not a mechanic) and after exhausting most things he put it down to the 'inhibitor' which needed coding, and only BMW could do this. When BMW started coding the car it then decided not to work (after my mechanic had tested this to death) The BMW computer didn't bring up any faults but the 'technician' decided it was the key. £300 ish later new key and coded the car now worked - past tense. Until yesterday when now the car decided not to work but when turning the key, the car does turn over and engages the fuel pump. I was never 100% that it was the key but it did work for a while. We have exhausted all the usual poor connections etc, I just don't have 100% faith now that BMW will fix without just replacing everything.
