Engine Management Warning Light on 156
Having a bit of a problem with the engine warning light coming on (156) but only after she has been traveling for a good while. Around the city it never comes on. Had diagnostic twice at the garage. Result was the connectors needed cleaning. This was done and the car passed the MOT. However, after going on a reasonable journey (10-15 miles+) it comes on again.
Also, when the warning light appears, the cooling fan comes on even though its been very cold outside. (Must be temperature/ electrical related?)
If I then stop the car and switch off the engine then restart it, it goes off as normal.But reappears several miles further on down the road.
Whilst all of these problems are going on the cars performance is unaffected.
Any suggestions welcome?
