1.6 Coil Packs.

Changed my plugs at 33000mls (3000 mls early according to Renault's schedules) in Aug 2018 for NGK triple electrodes so they should be good for some time yet.

Actually noticed a difference after fitting them.

Have now done 45000mls.

Recently been getting occasional just perceptible misfire so suspect coil packs.

Changing them should be an easy job for me to do & not too costly but interested in what is the typical life of these packs.

Has anyone had the coil packs on their 1.6 changed & if so what was the mileage?

I changed mine not long after getting car. Did the plugs and coil packs in one go, plugs looked to be the originals with about a 1 8mm gap so I guess the coil packs were too. Mileage was about 52000 and it definitely made engine smoother and more responsive, with a bit of increase in mpg too

Mines had the coil packs changed and it’s only done 35k. It’s a common fault on the Wind and Twingo!

Thanks for info folks I think I will replace mine in the not too distant future.

Better to be safe as we have another Alpine trip taking in France, Switzerland, & Italy scheduled for June.

Definitely worth it my friend!

One of the favourite failures in both wind and twingo is coil pack closest to air filter as it gets dripped on by the screw fixing in the vent grille at back of bonnet where the two grille sections join. Lots of info on all the forums about it

I've placed my order via Car Parts 4 Less. Cheaper ones available but went for Bosch discounted to £28 each.

Re the drippage I did notice that when I changed the plugs there was more corrosion around the end plug.

Plenty of Lithium grease is the order of the day.

I went for Bosch units on mine!

Fitted coil packs this morning. Job went by the book with no hassles.

Fortunately when I changed the plugs a while ago I'd put plenty of "white" Lithium Grease on the tips & around the seals with the head when I put the coil packs back so they came out no problem.

I repeated the generous greasing when I put in the new ones.

Car now runs a treat but is the improvement in my head or real? Certainly no sign of my "just perceptible" mis fire any more.

Out of interest I measured the resistance of the primary coils on the original packs & they were all identical at 0.9 ohm so no obvious failure of one of them. 

When I measured the resistance across one of the new Bosch packs the reading was 1.2 implying the Bosch had a bigger winding & hopefully better spark generation.

OK I'm £112 poorer but I feel confident it was money well spent as preventative action against a possible future failure.

Interestingly the old Renault branded coil packs were "Made in Germany" whereas the new Bosch branded packs were "Made in Turkey"!!! So what: the Wind was built in Slovenia!

Glad it worked out for you mate!

It may be worth doing a ecu 'reset' by disconnecting the battery for an hour. I never did it when I changed my plugs and coils but last weekend when my battery died it obviously did it and I have gained a couple of mpg and better acceleration since the ecu has relearned the engine specs and the engine runs smoother than it did too. Just read my post re windows first!!

Thanks for suggestion.

Much on the internet re resetting engine ECUs with varied advise all round.

When I had a problem with my lights on the Wind I bought a new light switch unit for about £140 to no avail.

As a last resort I reset the lighting control unit by pulling suitable fuses which cured all my lighting problems.

The details are in a thread somewhere on this forum.

Re the ECU: At present I'll probably let sleeping dogs lie as it is currently running well.

I thought I'd pick Renault's brains & have e-mailed them the question.

I'll report back on their response in due course.
