2014 E400 Coupe
Hi, I have a 2010 E350 cdi coupe that ever since I bought it in April has pinking. I know diesels are not supposed to pink, but when accelerating hard there is a distinct sound. The dealer says the car has all the latest software updates and has now covered 6500 miles. Performance is good and fuel economy is..well...ok....high 30's on a motorway run and low 30's in town....anyone else experience pinking?
 
Thanks Johny, I will get them to look at that and reset the injectors
 
I am going to try this Millers Diesel Additive I seem to read about a bit on here, sounds like that may help a fair bit
