Hi All,

I have a A180 CDI, 2005. The fault codes on the car are P0299 & P0401. I have replaced the EGR Valve but the car is still very sluggish with poor acceleration and it will not rev over 3000. However if I unplug the Air Sensor to the left of the Air Filter Box then the car will rev fine and accelerate fine; does this mean that the sensor needs replacing as I cant find the part online any where??

The part nos on this part are:
Siemens VDO
5WK97003
A0000942948
Link to part http://autotekelectronics.com/newaut...%20A0000942948 but says it for a smartcar?????

Cant find this part anywhere if this is the faulty part.
Its on the outlet pipe from the Air Filter Box (to the left of the box as you look at it, 5 prong sensor if i remember).

Thanks

Paul
