Evening all, I have the above car at the moment with the auxiliary heater which is very smoky.I phone the dealer to get a price,very expensive,the parts guy said "there is an issue with them" but would not explain anymore.I have no fault codes but i assume its getting too much diesel. Has anyone come across this before or know how much colder the car would be if it was temp. disabled ?..price is causing the latter action. Any ideas or know fixes out there i.e can an injector be bought separate or know about "issue" Thanks for any suggestions. Cheers, Dave.
