First cold day around - 2c and started the e61 530xd, let it idle for 5min and went... When i reached around 90kmh it shut off. Restarted and reached the store, checked code. Was for injector 5..its new bosch since 3months.

Cleared it and went home, all god at higher speed untill i accelerated.. Died and showed all injectors actovation. Died one more to home.. All in 10min


Checked with protool, battery voltage, alternator, fuel temprature aswell engine temp.

All good, all was as it should.

Went for another drive... Doesnt matter now how i drive.. I can put it to the floor from standing still up to 200kmh if i want.

Just keep on going.

What should i check... What could it be..

Bad fuel?
