Hi all

i have a A170CDi auto. It failed its emissions test. The reading should be 2.50 but is 3.20-3.40. Its not out by much but it refuses to come down. I have tried the diesel magic stuff to reduce the smoking which has worked in reducing the smoke to virtually none but the reading is still not coming down.

If anyone can shed some light on as to why i am having this problem, or make suggestions to solve the problem, it would be greatly appreciated. The diagnostics are suggesting that the car is perfect and there are no faults. PLEASE HELP

Thanks

Hi i am new to this so forgive me!!!!!!!
I own a a class 170cdi advantarge auto 51 plate, i have a leak underneath which is not coming from the engine. i think it is the gearbox as when i looked underneath there was oil dripping from a hole about 1/2 inch in dia. the hole is in some kind of housing. when engine is started something in the housing moves around like the clutch/flywheel ?????
I hope one of you brainiacs can help. Thanks..
