C220 CDI Mercedes very heavy power steering at low revs when parking, anyone help with diagnosing the fault? thanks

Try pressing the ESP button for 3 seconds, (See photo), to check you haven't pressed the button by accident. If not, try this website.

Mercedes ESP light warning How to RESET it yourself

does it have a check engine light? You need to have it scanned and yes it could be a mass air sensor, dirty fuel filters and air filters can cause this too.

It is usually a ABS wheel speed sensor has gone faulty, but you would have to have electronic diagnostic done to read off a fault code (DTC) and maybe a live data scan . Hope this helps

Does this car have a valet system on it?

weak battery in key most likely

Maybe have the power steering fluid flushed and filled. Check belt tension, any slipping?

P1664 FIP (Fuel Injection Pump) malfunction (possible air ingress in low pressure fuel side)
Most likey the Diesel fuel injection pump needs to be replaced or overhauled.

Sounds to be a loose or corroded wire/s at either starter motor or at battery fusible links.
Also check the earth strap (Cable) between engine and bodywork.
Hope this helps, MMP
