Please advise I really feel desperate right now.

Thanks!

If the dealer actually called it a spark plug, then run away very quickly, because your diesel doesn't have spark plugs. If he called it an injector, then fine. If he called it a glow plug, then that is different again.

It seems early (in terms of mileage) but injectors can fail. There should be a diagnostic code that leads the dealer to conclude that an injector needs replacement, either because it is leaking, or because the spray pattern is not correct.

The price is high. You can get another quote for the job to decide if you want to the dealer to do it, or an independent garage that is familiar with BMWs.

Some things that cause a bad injector could cause the same problem in other injectors. It goes back to the codes, though.

Another poster with a 3.0d could comment on how common injector failures are at five years.

Good luck.
