Morning all. On our W211 E320 there is a very strong and unpleasant diesel type smell when the car is ticking over. It's an exhaust smell rather than a fresh fuel smell. Has anyone else had this problem?
Looking forward to seeing your replies.
Thanks

Exhaust smell and diesel smell are very similar in if you have a knackered injector seal.

I recently had a duff seal on my s212 350cdi btw. To check, lift bonnet, take engine cover off and have a look/listen. If there is a chuffing noise and deposits of black tarry crap anywhere then an injector seal may be the culprit .

If not then ?cracked exhaust manifold.

Is the smell constant or does it come and go?

Injector seal isn't a massive job btw. Cost me £98 to get sorted.
 
Thanks for your reply. From memory the smell is always there when stationary. I will have a look /listen and hopefully hear the sound. Hopefully it isn't an exhaust issue as we have spent over a thousand pounds on the car this year having the front suspension rebuilt thanks to the potholes around here.
Thanks again
 
Do you only drive short journeys? If so, the DPF may be getting clogged.

No DPF on OPs car.
