Hi, I've a 2002 1.6 Laguna that has electrical faults that 3 Renault garages have failed to fix. It started several months ago. The car would randomly start to rev up and down uncontrollably. The electrical fault light would come on, usually it would remain off after restarting the car but would light up again if the car was either left ticking for a few minutes or turned on and off a few times (makes city driving impossible). First garage replaced the throttle body (twice). Another garage just tried resetting the computer (several times over the space of a few months). Most of the times it seemed to improve the situation for about a week, although once it returned worse than before the reset. Toxic fume warning light tends to come on if the electrical fault light stays on for a length of time. Most recently, replacing the computer was suggested but that proved to be a disaster in a car with similar problems. Replacing the wiring loom has also been suggested. I dont know what to try, it has cost me a small fortune and still has all its problems. HELP:confused:

Sorry, I forgot to say the TDC sensor was replaced, also new coils were fitted (just to eleminate that possibility). Have you any more info on inlet temp sensor? Nobody suggested that yet and I dont even know what it is !

Also check that fuel injectors are not blocked or partly blocked, If low fuel warnings have occured then the crud from the bottom of the tank could be a problem.

Thanks for trying to help but I'm afraid thats not the problem. I'm sure it must be something very obscure (remember 3 Renault garages have tried unsuccessfully to fix it). I'd love to hear from anyone that had a similar problem, even better if they found a solution.

Blimey Mitty,sounds like most of the electrical system has been replaced!.:)

If possible,try a local independant Renault specialist.If your anywhere near Portsmouth,try Rentech(search for [email protected] on the forum.).Seeing as you seem to have most things replaced,any advice I can give you would have been covered before.The ECU or wiring loom could be the cause,but it's an expensive guess either way.:eek:

Good luck.:)
