Problem starting E46 320d 2001 "Y reg"
I'm not sure, (because I don't live in your area), how many other shops you have to get your car checked out at, (my guess..not many shops that deal with your car)..like a physician for your health...get a 2nd opinion.
As far as "A Few" metal shavings not being a "BIG deal"..they're only telling you about the filings they actually saw. Depending on your fuel filter size, the ports (or opewnings) that let fuel flow through could be plugged enough to restrict a good flow. The size of the Microns would deterine that along with how big teh filings are, and really...what is causing the filings in the first place.
Diesel is not a really pure form of fuel in the first place, and the station you fuel at could be the main problem, if they're not dispensing good Diesel.
You should always start with the most obvious remedy I'm not sure what 2000 pounds converts to in US dollars, but think about what you paid for the vehicle vs buying a new filter.
Dirty, or partially clogged injectors would also give you the same symptoms.....dirty injectors will restrict the flow of fuel until there is enough Diesel in the cylinder to ignite. You have to remember that Diesel fuel is NOT ignited by a spark, but rather by compression, so if there isn't enough fuel in the cylinder to ignite...it simply won't.
Food for thought about running a Diesel, and I like Diesels alot, depending on where you live, and the amount of driving you do, consider putting your fuel filter on an annual if not bi-annual maintenance replacement schedule. It might cost you a little more for preventative maintenance, but it's a whole lot cheaper then a repair appointment, and you'll llike the vehicle alot more if it's running well.
I hope this short novel helped you out some, and thanks for letting FixYa take a shot at analyzing your problem.
I know it sounds like a alot, but it really isn't that bad
