2. The fuel consumption is suddenly much higher than usual. Normally with mixed city/highway about 8liter/100km but now 10 liter/100km. See this video how the fuel economy gauge acts weird - with very gentle acceleration the consumption gauge goes all the way to 20liter....


Any ideas guys? It would be great to have your comments.

I have had new injectors installed (all 6), new coils (all 6) and 6 new spark plugs only 6 months ago. I have just replaced the NOx sensor, but this did not improve anything.

Now all my spark plugs are totally black....like the picture attached.

There are no related fault codes.
I have replaced parts exactly like you along with valve cover gasket, solenoid and have pretty much the same issue with my spark plugs and random high pitching noise apart from that I do not encounter the fuel consumption issue (yet). Replacing spark plugs cures it however there must be something else killing those spark plugs. I have been to many BMW specialists however no one could get to the bottom of it. Have you by any chance came across anything to solve it?
