Hi,
Have a 1.2 2011 Leon. Have had some issues with misfire.
Coil pack replaced 6 months ago - Issue resolved.
Slight misfire reoccurred some weeks later - main dealer diagnose it to a lead issue. Problem resolved...
Again issue reoccurred some weeks later - all leads replaced. Problem resolved...
(A bit of a trend here :)!)
Anyway yesterday I noticed that a slight misfire is back (4 months driving ~3k miles) - this is how it normally starts and gets progressivly worse.
All replacement parts were genuine from the main dealer.
I have read some occurrences of this but haven't read of a definitive solution.
Any thoughts on a long term fix for this? I can't keep going on replacing leads every few weeks!!

(Timing chain was replaced less than 5k ago).

Thanks!
