Having problems with your 1999 Mercedes-Benz E-Class ?

Merc 280 cuts out at just above the 80 cent level

\015 I recently bought a Merc 280 1996 and what a smashing little car. All of a sudden at a junction it cut out.......when I hit the ignition it turned over until it timed out but no start.......Petrol OK etc.....After a while it kicked in. Hmmm whats this....Drove for a few more miles came to rest at a junction ant it cut out again....same thing. I noticed that the electric fan was not kicking in with the ignition on and it was just above 80 degrees on the guage. This appears to be the problem as it will always start if you allow it to cool. I banged 9 volts onto the electric fan and it worked fine so I then begans to think of either the sensor or is the ECU controlling the output to the fan from the sensor...? Well to cap it all I run her up to temperature, the electric fan was ticking over quite slowly but the radiator panel was cold.....is thios normal or are they that efficient....? So any ideas would be appreciated.......Steve Ball Stoke UK.\015 Posted / edited by AnonymousUser on : 19-02-2018

Answers :

It is a good car. You just have a minor problem. Replace all thermal sensors on top of your engine. One to control the cold start valve, itf it is bad it gives erractic resistance to confuse the ECU. One is to turn on the electric fan when the engine temperature hot. If it is bad giving out of range resistance reading, then you have the described symptom. Good luck.
