Boconegra Misfire and oil consumption

Apr 12, 2022

o recently bought a 11/12 plate BOC with the CAVE engine, 60k
Has a miss fire at higher revs occasionally, I’ve changed the plugs the NGK ones gapped at 0.6. The old plugs (pictured) from 1-4 L-R any ideas on them? I done a comp test and they were all around 150-154 psi. Not sure what to do with misfire now, maybe coils? But my biggest concern is oil. I must of put 2L over 600 miles in it. Seems mental to me. I also get a puff of smoke when pulling away from slow speed, but it’s not there long enough to see if it’s grey or blue. Any ideas on what is happening? Cheers. Misfire is resolved by turning car off and on again

Maybe have a look for "Lucifer's guide" on this forum, as, I seem to remember, he did a lot of work on that version of twin charger. I might have the name or the guide spelt slightly wrong, I'll update/edit this posting if/when I find out!

Edit:- https://www.seatcupra.net/forums/resources/1-4tsi-twin-charged-fundamental-problems.67/

Another Edit:- you will find more on this on the Skoda Fabia forum, Briskoda.net as many MK2 Fabia VRS owners have had similar troubles, surprisingly there is either not much or nothing on the VW Polo forum where the 6R Polo GTI also used that engine, it does seems that most of these engines were gems, but also very flawed gems!
