on my way to mallory park on saturday,cruising as you do at 6.30 in the morning,slight loss of power,loads of smoke and some engine vibration,low loaded back to east kent audi. Three days later,no compresion in number 1 cylinder ,broken spark plug in number 2 £125 JUST FOR THAT .1000,s for repair. any ideas.

John there was a similar report like this on another S3 a while ago on here - possible culprit is lean running? Likely outcome is piston knackered and possible damage to cylinder(s).

Also Chelsea Mick had the same before Xmas - new engine was final outcome.

Sounds like excessive heating starting at number one cyl and spreading to number 2. Mine failed on cyl 3 and started a bit on cyl 4. Jabbasport are picking mine up this week for rebuild so will know more soon.

Hopefully your head isn't too damaged maybe replace a couple of valves. You've probably melted a piston but hopefully nothing large was sucked into turbo or that will need replacing too.

I pulled over immediately and was towed home. Something to do with lean running??

I have some pics of my engine on my thread if your interested.

already seen your pics. just not very nice when you know its going to break the bank to fix.99 v its only worth £10 ish can we justify £2500 just to get back on the road. should have kept s2

Yeah not very nice!

still not posted costs,would like to know.tempted to put in new enginr

thats it my s3 went on a low loader today, of to qst for repair work.cant afford a brand new engine,but kim has sorced a 225 with 30k on it, its not what i would like to do but its the best fix for the money. hopefully ill get it back the early part of next week.new water pump,new cam belts,and a new MAF which i think was the cause for my engine eating itself.sould get some change out of 3k,having it rolling roaded while its there
