Yr. 2000 1.4 Scenic.

Wife rang me today, Scenic is 'juddering'! Got home tonight, engine missing, pulled the coils off and one of them is very wet so I think I've found the culprit.

The last time it happened about 5 years ago I replaced the offending coil but i was wondering if they can be successfully dried out?

I've got it sitting next to my wood burner at the moment and I've removed the top cap and taken the rubber bit off the bottom.

I'll stick some new plugs in before I put them back on which is a job that always terrifies me on this car as they are so deep into the head!!!

I think if you did dry it out, you'd only be putting off the inevitable.
I always carry a spare, since our first Mk1 Ph2
They live in a harsh environment, heat mainly, which breaks down the insulation. In the early days, Not just Renaults but all Audi's were off the road as the coils were failing faster than they could be made.
IMNSHO you should buy two, fit one & store one.
One wonders from where the sogginess is coming?
Inspect the windscreen washer tubing for cracks, had this happen to me. Car fine all way down M1 & M25, got in town, washed windscreen 2 hrs later running like a bag of sh*te. Lifted bonnet, water pi55ed out from under the insulation. Re "terminated" washer pipe. Solved. I was lucky, but all my coils were new. I guess yours may not be.
Just my 2d.

Thought this would be the advice.

New coils it is. I always go to my local specialist and fit OE equipment (Valeo), they know me well and I get the coils for around £17 each, how have you found the cheapos on ebay?

Never bought from ebay. Just bought the cheapies from local motor factor. But if you can get Valeo for £17 then brilliant.

All fixed. I was advised to change them in pairs, 1 and 4 or 2 and 3. The ones I fitted were in Renault packaging and look slightly different to the Valeo and they have a large green spot on the top.

I changed 1 and 4 and it's 'sweet as a nut' now, unfortunately they were out of stock on the plugs so that will have to wait, I got the coils for a little over £18 each so I'm thinking might be a good idea to change the other two just for peace of mind.

By the way drying them out didn't work!!!!

The Green ones usually are Valeo. Never changed them in pairs. Matters not, it's fixed & quickly too. Back in SWMBO's good books too :d

Does anyone have any views on plug manufacturers? The last time I had to replace a coil we were on holiday in Jersey in 2010 and that was the last time I replaced the plugs.....eek.

I put French plugs in then and they have been great. Can't remember the make.
