Re: Renault Scenic - Faulty Coils Causing Warning Light(Including General Info)*fixed

I have just bought a 1.4 Y reg Scenic that has developed a misfire. I bought it from a dealer last week and it was fine until I used the washers the other day. I looked online and found the article about rotting washer pipes, sure enough when I looked yesterday the main pipe was perished and the top of the engine was wet. I bought some new pipe and while fitting it last night snapped the end off a washer jet! I bought a couple of new jets and fitted them this morning and got it all piped up. I still have the misfire though so ordered four coils from the bay. I don't have a dash warning on but the misfire is getting worse. I'm sure the coils will sort it.

Welcome back.
Have you looked at the coils ?
Bet there's a puddle / condensation round one of them.
Worth changing coils anyway. Keep a known good one in the boot, I do.
You can sometimes find which is faulty, by disconnecting the injectors one by one, not the coils as they fire in pairs.
IMHO petrol Scenic's are less doggy doo than the Diseasel ones.

Cleaned them this morning and 1 and 4 look rough so am going to change the lot. Hopefully they will be here tomorrow.

Did any of them smell burnt or have any swelling? Sometimes they show themselves.

Looking up the spark plug end in the sunshine 1 and 4 looked white and the outer rubber cover was separating. 2 and 3 looked perfect so assume 1 and 4 might both be a bit dodgy.
