Hello everyone.

I have a 2016 L405 with the SDV8 4.4 engine.
Previously had the same engine in an LM322 and...the same problem. Wasn't able to really fix it as well.

Situation: it smells burnt in the cabin as soon as the vehicle comes to a stop after driving, especially when the engine was under strain. Always. Comes out of the upper ventilation slots.

First of all: the oil cooler has new seals, and the two O-rings on the turbo oil line have also been replaced. Everything in the V is super clean, as are the turbochargers, nothing is sweating, nothing is wet. Dry. It's absolutely dry everywhere.

Does anyone have any experience with that problem or ideas where the source of it could be located?
Thanks in advance.​

Thank you. Yes, I've heard of that but it's Summer here, almost 30°C and the FBH shouldn't work actually....
