Afternoon All,
Thought i'd give you all an update on the car. I ended up changing everything at the rear for the handbrake plus 1 of the callipers as it started binding after replacing the rest.
The 4WD ended up being a bit of a mission to sort with a lot of strange questions raised.
Firstly the PTU that was removed is a recon unit, however no garage that's worked on it previously has any records of the PTU being changed and the bolts where merely finger tight. The unit itself seemed off as there was very little resistance when manually turning the PTU compared to the new unit, and the splines had sheared on the gearbox end of the sleeve, with no corresponding damage or metal residue within the gearbox side.
Then after replacing the PTU and servicing the Haldex (looked much like the picture above) everything looked good. However after a simple test drive by the garage the "Transmission fault, reduced traction" message popped up on the dash. Reading the code it appeared to be a solenoid issue, so having heard about that before from their transmission specialists the garage completely stripped the Haldex, blew out all the gunk and refitted it. This has resolved the issue however the Haldex had a couple of bolts that where not standard (random bolts) and 1 had been ground down and rounded. So although the car seems to be working i'm still a little weary about pushing it as it seems to have had a fair amount of bodging done to it previously.
If anyone has an green lanes around buxton that they know would be good first lanes to test the 4WD properly or are willing to join me as rescue then please let me know.
