Recently purchased my first BMW after a long time waiting (and saving) have read a lot of useful information on here regarding the problem I am currently experiencing. My 320d is 2000 excellent nick, nothing untoward until........... an intermittent problem with the turbo. I have seen a lot of useful info about the MAF and ERG, Its going on my mates diagnostic machine tomorrow afternoon but a couple of questions I would really appreciate an answer to first How do I know if I have the old MAP sensor or the newer one which needs to be coded? is there an easy way of checking whilst diagnosing?
Should I attempt to clean or have him order me one from trade before I get there? its seems to be the most common fault
Is there anything else I should look for?
Has anyone had a similar experience which didn't turn out to be the MAF filter?
The turbo was replaced at high expense by a dealer less than two years ago and I have the receipt. It pulls great so the turbo itself is fine, there is a chance it could have been shoddy workmanship and a cheap pipe or hose has a slit crack causing the loss of pressure, hopefully the Diagnostics will narrow it down but I would really appreciate any feedback at all.
