I picked up my 2011 last may. not had any reliability issues. just wear and tear items.
I did have mine remapped at the start of February, to find out it had the type uk330 remap on it from the factory( this wasn't obvious without a dyno) So the horrible factory lean map wasn't on the car from day zero.
Does the car advert have any performance pack such as the 320r 340r or other such packages? As having one of these could further improved reliability. As the ringland issue is down to the cyclinders running too hot due to the poor map/lack of fuel. so mines running 11.1 AFR on boost. but was healthy with the off the shelf factory performance packs. just needed timing and specializing to the car.
Do you have an advert we can look at?
