intermittent fault

[bazzyi]

My 220e Sportline keeps breaking down. I have been told there is no spark or fuel but the car is turning over. Been pointed towards the immobiliser but have had it checked & been told it is working ok. Anybody got any ideas?

the cps is a very common intermittent fault No5 in the link http://www.detali.ru/cat/oem_mb2.as...717.412413&CT=M&cat=19K&SID=15&SGR=075&SGN=04

Hello Bazzi and welcome, the CPS can fail often good when cold but engine stops when warm, you can measure it and it should be 1k ohm when good

Thank you both Television & Roofless, my car is in with auto electrician at mo. He has said he has checked the crankshaft sensor & it is ok but if the car is running it will show as it is working ok. Will mention to him again about c p s & see what happens. Thanks once again for your help & will post the outcome when i know

It should be with someone that can read the diagnostic fault codes on that generation of car.

The fault code readings are very reliable and he/she should be looking at pin 8.

thanks all. auto electrician said he found a dry solder joint in 1 of the fuel pump relays. He re-soldered it so we will see how it goes. Thanks again for your help

Yes the PCB is known to get dry jointed, many replace it and I do not know why as they are so easily fixed

Hi
the other possibility is over voltage protection relay
