Good to have you guys back, you were missed. I think you have to be an Audi enthusiast and have deep pockets to run something like this. I had a couple of Audi's when I was younger but I'm too old for the hassle of the over complication and unreliability. I do like the Audi engine plant in Gyor, Hungary.

Not great for such low mileage cars. The air to water intercooler appears a real problem point. Note to owners to find that water leak earlier. Great video. Excited to see the S4 problem.

[@scunnerdarkly4929]

It goes with the territory. Few of these cars are going to be driven kindly and while not every owner gives their car a regular beasting many do, and it doesn’t help with longevity. More importantly Audi know these cars are going to have a hard life but they’ve only got to survive the warranty period and then it’s no longer Audi’s problem. Over-engineering isn’t a thing these days with volume manufacturers hence the number of plastic components we see around an engine in the name of reducing weight, and while they’re lighter they’re cheaper and quicker to produce - and usually good enough to hold up during the warranty period. Usually.

Probably sensor will be gone on the motor . Can’t be replaced individually, they only sell it as whole unit -2500£

@@VAGTechnic 100%? Sometimes some odd component parts can be obtained, like the Borg Warner solenoids in the DL501. Just a guess though.

Not enough petrol in the tank
