Car was firing on 3 cylinders suddenly so i changed the spark plugs in my s3 ran well for a day then the loss of power under load and misfiring started again which leads to coil packs playing up but no faults coming up on the ethos.
I have the bolt down type coil packs
I was thinking of replacing the set but don't know what's best as I heard you can fit the red coilpacks from the 2.0 tfsi I this correct and if so is there a certain year or is it all of them?
Or there's an upgrade set on eBay for £90 but are not bolt down. Does this mean they won't sit properly or are they a different design that works without bolting down?
