C220 CDI Loss of power

[Justin0609]

I have a 2006 C220 CDI, 65k miles. I have stared to experience loss of power on a few occasions, there is no fault light but I have noticed a "whooshing" noise when I accelerate, as there is not enough air getting into the engine (Turbo) !!

Any ideas as to the fault & remedy.

Thanks

Exactly, check your turbo hoses... (black smoke also indicated insufficient amount of air).

Exactly, check your turbo hoses... (black smoke also indicated insufficient amount of air).

To explain further, you probably have a split hose or a poorly fitted hose clamp. This allows air measured by the MAF to escape. This results in excessive fuel injection for the amount of air actually entering the engine. Thus black smoke and a sensor telling the ecu that you have a problem - hence limp mode.
Check carefully for splits - they can be hard to spot.

Thanks for the info, are the hoses easy to get to ?

Yes there are 2 on either side of the intercooler, one from the turbo the other goes to the inlet manifold held in with push fitting clips.
