[oilit]

I have been living this nightmare since Christmas, and tested everything - replaced a leaking front mount but didn't fix the problem, I bit the bullet and swapped the turbo for a known good one - and hey presto the engine service and limp mode has gone.

I will probably take the turbo apart at some point to see what the cause was - as mine too only did it when it was cold.

Thanks to this forum and SiRobb videos online as without them I wouldn't have managed to find the fault and didn't want to go buying Vida etc.

Worth mentioning that I managed to get the turbo out through the top also without removing the engine - although with the time taken I would argue it probably doesn't save too much time and if I were to do it again (prey not) I would lift the engine out - trying to get the two small screws in for the oil pipe when crawling underneath is a real PITA.
