Please could any of you help me. I have a 52 reg mondeo tdci, its recently had oil, and filters replaced and is now kicking out black smoke under acceleration, i know a little bit is normal for a diesel but this appears to be quite excessive. It's due its mot soon and don't want it to fail on emissions, so please any advice/solutions would be most welcome
Thank you

Have you noticed any diference in performance ??

Yes, the throttle response is extremely sluggish and slow to pick up, seems to lack mid-range grunt as well.

try the fuel filter mate,

EGR valve stuck open mate very common. It will feel like a different car when you put a new one on.
