    in race trim its turned down to tractable(ish) level
    on full chat it will spin up every gear in the dry, so not much point.. We have to use list 1a tyres for combe saloons, which is regular tyres.. not even track day rubber, so that limits power effectively. Its nice to know I have it is about all I can say - lol

    OK, so to re-rail - the Haldex is not working at all again this morning, making the yellow thing like a nuclear bomb with no guidance system.

    I was hoping really that this problem would just go away, but sadly that appears to not be the case. Booo.

    Will go out and scan it in a bit.

    Is that question for me? If so I changed the controller, from what I know the pump is separate I think.

    Activate the haldex oil pump in output tests and get underneath to check the pump is buzzing away. When I replaced my diff, I fitted the new one to find it didn't work for 2 reasons.
    1- my replacement diff was off a 03 R32 with esp and mines a 99 apy with no esp. The late ESP controller did not work with my non ESP car. Weirdly the r32 haldex ecu wouldn't even communicate with my abs (can bus difference possibly?)
    2- the replacement diffs oil pump wasn't working properly and made the car run in 2wd all the time.

    I ran the output test earlier and I could hear the haldex doing it's thing. Have been driving it about today as well and have had no AWD issues. Intermittent at best, and the front only seems to spin in the wet.

    I wonder if the haldex is still working, but the front tyres just can't grip in the wet. Not sure. Weird. Having said that, had noises from the back recently which have stopped now, and a haldex fault code... It's got to be on it's way out to be fair.

    I hate to say it, but trying a simple oil change may do the job? Iv read loads of times that this fixes alot of problems

    Did consider that - only had one done inside the last 5K ish though. If problems continue I might before changing the whole diff.
