So my car has developed a miss-fire
« on: 20 January 2022, 22:25 »
Just dropped my lads off to school and on my way home the car lost all power and the engine felt like it was gonna jump out of its bay ! Left it to idle and opened the bonnet engine was shuddering - managed to limp it to a garage and they have advised it’s possibly the coil pack ?

Any advice if this could be a can of worms opening for further issues to arise ? Thanks (don’t seem to have much luck with this car at the moment) I am thinking of px it for a mk7 /7.5

Did anyone connect to the car and see what codes are being generated? Or just assumptions?
It could be a coilpack which has randomly failed given the age of the car, but it could also be numerous other items.

I broke down on the motorway yesterday because of another failed coil pack.  This is the third time it's happened to me in 7 years of driving my GTI mk6.  The AA fitted a new one for me by the roadside.

In light of this incident I'm going to have a look at getting the "uprated" red top ones fitted if they still sell them.  Are the ECS tuning ones good?  I'd appreciate any recommendations.

Dont know about the red ones as never seen the point. Iirc and its 10yrs ago now but when they were new there was issues with the EU made coil packs. Iirc if it had a H on it it was a Hitachi one and was good, Otherwise it was going to fail at some point. Think thats right anyway would have to search it out.  :smiley:

It is advisable to replace all 4 coilpacks when one fails. Did you replace a single coil at a time when they failed?

The "upgraded" coilpacks aren't really necessary. They will last as long as a stock coilpack lasts.
However if you're wanting to replace the entire set and they aren't much more expensive than stock coilpacks then go for it.

Yes over the years as they've been failing I've just been replacing the one that's failed rather than all of them.  I do have a Stage 1 on my GTI and that may have something to do with it.  I think this time I will replace all of them with the red-top ones.
