Just ran it again twice "back-to-back" as requested - the pump and clutch etc DIDN'T activate (not audiably anyway) on the 2nd test, but they did in the first.

1st test:






2nd test: (note current is zero because pump didnt activate in the 2nd test)

Thanks, My haldex is acting same. Did complete test on pump part by part, it work perfectly. Haldex oil service is done. Solenoid is also working. So it is either controller or complete haldex diff. Getting HPA performance haldex controller next week.
If it solves my problem all good. Otherwise long time frontwheel drive.

Finally haldex module showed an error code which is

Why don't you get VW dealer to diagnose it?
You must have the new car warranty, it's 2013 model. Even, if they wouldn't honour your warranty because of the mods, at least you would get "an another opinion".

Have a look on Ross-tech as they have explanations for a lot of the faults there.

It would be my last option. Removing all mods and flashing back to original going to be costly and risky. That's why I need to diagnose before and if it is complete haldex failure all back to stock and go to the dealer. It is all about cost benefit analysis.

Either the way you taking a risk that they will find out that the car had increased performance. So, if it was me, I would play fair and took my chances and drive to the dealer with the car as is.

So after reading this, I may have a similar problem. It never occured to me as the car only has 30k on it but when the front wheels start slipping there is no power transfer to the rear wheels and the its stuck spinning just the one front wheel. Although this has only happened twice, once on snow, once on a slightly muddy surface, it does however screech wheels on hard take offs. Is this normal behavior or a likely fault?
thanks in advance
