the light stayed on for a few weeks and I didn't do anything about it. Then another coil blew and when it was replaced - by magic the light went out.

So, those who said it was a coil : yes, you were right.

but why? the car was running fine. I assume the coil must have been failing intermittently, so mis-firing on the cylinder and so blowing petrol out the exhaust instead of burnt petrol hence lighting the light. However, I didn't notice any misfires.

I can't believe how unreliable those coils are.

Renault scenic coil packs

Hi

Can anyone tell me how easy it is to fit one. What do you have to take off and how do you diagnose which one has gone?

Had the car a year (1.4 petrol 2002) and this is the third one gone!

They are very simple.

If you have the silver plastic cover over the top of the engine,pull the front edge up and slide it towards you to remove it.Then unplug the offending coil ,undo the T30 Torx headed bolt and pull the coil upwards to release it.

Issa eassssayyy!

To find out which one (actually they usually go in two's) just disconnect one at a time and see which one doesn't effect the running of the engine, and that will be the one.

Big problem with coils on these Renaults; all models seem to be suffering. It was suggested recently that the covers over the engine are cuasing them to overheat and fail. It has also been suggested that the cold weather is causing condensation to freeze on them and then stripping the insulation as they thaw out. Take your pick which to believe but it is irrelevant really.

Did the others go in cold weather too? When did they go? As it is over five years old it may be difficult to get RCS backup for replacements but if you have been replacing these throughout its life, you may be able to obtain a goodwill gesture from them on the basis that you were not informed of the existence of this known problem which Renault decided can be prevented by replacing ALL coils the first time the problem showed up. There were some bad batches of coils put on during the build. Worth talking to your dealership if the car has been properly maintained; ask them to approach RCS on your behalf. The answer will be no first time round (I'd bet my willy on that) but you then write to RCS at Renault.co.uk and hope they will look at it favourably.

Read up on the problem here on this forum... Lots of threads to read. Three in a year is a lot; do you know if the previous owner had the same problem at any time? Also, if Renault replaced any of these and they have gone again, you should not have to pay again as they should be warranted for 12 months.

If you give us some history, we might be able to advise.

To test them,disconnect the injectors one at a time and not the coils .The coils are wired in pairs,so if you disconnect one it takes another one out too.(Hence the amount of people on the forum who have had two replaced at the same time,when one would have fixed it........)
