I come to you all desperately seeking help....
Around a month ago, I posted looking for help with my 1998 1.9 Z3. Recently resprayed after around 18 months of restoration.
A few weeks after the respray, I took the car to work for the day. On the way there, on the motorway, the car cut out and shortly before it came to a stop there was a loud bang from the exhaust which then had a lot of black residue on it. It started up again and got me to work but then did it again at lower speed on the way home. Exact same symptoms at that time. The car was also using a lot more fuel than normal.
The car has been in the garage since then and when it was running the emissions were far too high.
The garage has checked for vacuum leaks and 2 were found and repaired. The car is now showing as having 'discreet/zero' vacuum leaks however still had emissions which were excessive.
The garage confirmed that there was no blockage in the exhaust. The compression was good in all 4 cylinders.
A code was present for the Camshaft Position Sensor (P0340). The mechanic carried out a manual test of the sensor and found it to be completely dead. At this point the car was starting albeit with the cutting out problem and excessive emissions.
A new BMW sensor was ordered and installed and the learned values reset and now the car won't start at all!
The car does start with the dead sensor replaced/no sensor installed.
The timing was also checked and found to be fine (the mechanic had believed that this was likely to be the problem).
The garage (who have been brilliant with me) have had to stop with their attempts at diagnosis as they have existing commitments and projects and they have been working on my car where they have had time as they took me in at very short notice.
I am looking at passing the car onto another garage to see if they can help get the car started and sort the emissions problem.
I need to find the problem and sort it as I have spent a lot of money bringing the car back to a good state what with the respray and all. I should point out that the engine seas running fine until this came about.
Does ANYONE have ANY experience of a problem like this or any suggestions of what this might be?
I would be seriously grateful for any advice at all.
Thank you all.
