Right, this is proving to be a right pain.....
Clutch, Flywheel, and slave cylinder were all swapped for new parts and ITS STILL doing this weird issue
To recap now it's fine when on normal cruise and partial throttle there is no issue at all its smooth as they day it rolled out of the dealership, the problem kicks in under heavy acceleration say when over taking the power comes in and you can feel the turbo pull the car then it looses power, stops pulling, the revs jump up 500-1000rpm and the car comes back in, naturally the turbo is no longer pulling as its lost pressure but if i keep my foot accelerating you can feel the turbo coming back in again
In all the years Ive dealt with clutch slipping it would always loose grip at a certain RPM and keep spinning after that RPM that being said i still replaced the clutch and flywheel on this car last week and changed the slave cylinder whilst it was all stripped out for the sake for €150 it seemed like a good move.
So now im nearly 2k deep in parts cost and the problem remains after the new clutch & flywheel.
I am at a lose trying to think whats mechanical, whats controlled by sensors, cold it be a faulty LSD im running out of ideas as im used to working on JAP cars
