When we bought 'Wee Oui' the sellers told us it needed some work due to an apparent problem under load.
A quick plug in diagnostic revealed faults with the EGR and the Air Flow, I know many people just blank off the EGR and get the system remapped, but it wasn't a route that we wanted to go down.
New EGR ordered, sadly we found that the EGR cooler was damaged so managed to find a s/h one on the bay of evil.
Air flow swapped off the old one and EGR replaced, the car now runs an absolute dream.
The Mrs has only driven it briefly for an hour but loves it, though she is missing her panoramic roof although the full climate control and ice cold aircon should help next summer.
Have discovered a slightly annoying suspension knock to the nearside rear so that's the next job.
