Sorry, the oil pressure was a typo. It should indeed have read 4-5bar
Well, things have taken a turn for the worse today as they have now refused to do anything about it by blaming the car so I may be without a turbo for quite a while as this drags out.
They are now saying the thrust bearing has disintigrated and this could only be caused by not enough oil or overboost, whilst completly refusing to believe that it could be the bearing itself or even the fitting!! I have answered every question and checked and double checked everything that they have come up with regarding how the car could have caused it to fail but their only response is "well it has to be loss of oil pressure or overboost".
When I pushed them about it they got a bit sharp and pointed out my warrenty is void as they fitted the bigger compressor, when I then mentioned statutory rights they started once again saying the warrenty was void and how it is impossible to check the oil pressure to the turbo without a "special adaptor" that fits the oil feed pipe! How the hell is that the only way when the oil feed comes directly from the main oil gallery where the pressure is measured and then passes through a standard pipe with no blockages!?!
Oh and to add insult to injury I was informed that if it had been repairable they would have just repaired it with a note to check the oil feed but as it will need replacing they are not going to do anything
I am currently writing a letter of complaint to them about this now, if anybody wants to proof read it let me know.
