Peugeot 508 Engine Problems
Why does my 2016 Peugeot 508 tell me to stop the engine while I am driving?
Hot engine oil is a normal part of a car’s operation. If there’s a little smoke from the oil when you open the oil-cap on top of the engine, that’s actually reasonably normal, provided it’s only a few fumes and not huge clouds of smoke.
The car telling you to stop could be due to any number of faults or conditions within the car, so the wise thing to do is have it scanned at a Peugeot specialist who will be able to interpret the coded messages the car spits out. The turbocharger could be the component at fault here, but without an electronic scan, you’d only be guessing at the real cause.
