Hello.
i wonder if anyone know why my 1,6tdi cayc start regeneration at to low temperature? this causes grey ish diesel stinking smoke from time to time..
it only happend if i shut of the engine while regen is active, and then for example next morning when start driving again with cold engine, it fire up regen after only few minutes/kilometers..
if regen start while driving with warm engine, there is no smoke..
so seems there should be a problem with a temperature sensor somewhere? but would think this would cause a fault code..? but there is none.. also when i look at actual values with vcds, all tempsensor seems to make sense really..
any ideas? the car have still have original sw from 2010, so never been updated. it seems to be worse now during summertime (70-90F outside temp)
cayc with abouth 130000 miles total.
