Engine cuts out when driving - intermittent. Solved.

If you are getting an engine management warning light and the the engine dies on you this might be the fix.I had this problem and Googled it for hours and noticed the same fix about 3 or 4 times. This is what I did:

• To the back of the engine block, close to the windscreen is a metal box. In our case we could just lift the metal lid off.


• Beneath there is an electrical loom. Looking at it closely I could see that the insulation on some of the wires had been rubbed off to reveal bare copper. We guessed the movement of the car had allowed the metal lid to rub against the insulation. Bad design really.


• Because this lid is made of metal it seems that every now and then it shorts out these wires and the engine management system light comes on and the engine dies. Bit worrying if you're in the outside lane at the time!


• I taped up the loom and pulled a piece of hard plastic over the top and then taped that in place on the basis that although copper was showing the wires weren't touching, it was the metal lid that acted as a conducter.


• Put the lid back on and it's been fine ever since.

I have seen all kinds wrong fixes for this problem but if you are getting an engine management warning light and the the engine dies on you this might be the fix.
