My c250 bluetec auto has a turbo lag on occasions. . Car has 9000km on clock. Is this normal

 

Wrong group. Please go post in C Class (W204). This group is for the W205.

 

Nope mine is a w205. . Bought it at launch

 

The point of confusion is that the W205 was introduced as a 2015 model, even though it was introduced in 2014.

As far as a severe level of lag, it's quite unusual but I remember a few reports of excessive lag being reported. I can't remember how they were resolved though.

In any case, it's not at all normal and, assuming it's not fuel related, should be resolved by your dealer as a warranty issue.

 

Turbo lag is pretty unusual these days, so I'd get it checked out or look for a second opinion. I have a C200, which is similar, and that has no noticeable lag.
