Limp mode

[smjohnson]

Hi new to this site,I have a Mercedes c200 compressor coupe, I have changed the conductor plate in the transmission, transmission fluid and filter and cleared all transmission error codes but it's still going into limp mode can anyone help with this problem. The diagnostic tool we used to clear codes was a snap on solo.

As has been said many times previously for similar faults, the ONLY way to get the full picture with fault codes is to use an MB STAR setup. Generic readers don't give the whole picture. Take the car to an indy specialist, who does have the proper equipment.

Oil level 100% correct when hot?

If its slipping then I expect the box is worn out or there is not enough fluid in it.

The air mass sensor fault will cause a lack of power and "can" mess about gear changes.

oil is level ok when hot its slipping in 3rd gear

it's just slipping in 3rd gear oil level is ok
