Assistance needed with 2016 BMW M4 exhaust emitting white smoke.


Recommended Posts

I have included a YouTube video capturing the emission of white smoke from my vehicle's exhaust. It is important to note that this video was not recorded on a cold start, but rather after the engine had been running for around 15-20 minutes.

My friends have suggested that the issue could be related to the turbo. I would welcome hearing any further perspectives from others.

The car's odometer reads 72,000 miles. It seems to be functioning well with no noticeable problems or sounds, save for the emission of white smoke.

I am located in the United Kingdom, next to the county of Cambridgeshire. I have scheduled an appointment for a specialised diagnostic at a rate of £140 per hour. Oh, I hope to get positive information. Various individuals on online forums have provided me with conflicting responses, suggesting either a turbocharger or a head gasket as potential causes. These are substantial expenses for repairs.

The occurrence of a head gasket failure is very uncommon, however turbocharger issues are not unheard of. Although not considered frequent, turbochargers are one of the most vulnerable components of the S55 engine.The rate of £140 per hour seems exorbitant. In comparison, I only spend £350 per hour at an independent garage run by a former BMW technician.
