Haldex HPP Install Questions.

[pansy]

Hi guys,
just purchased a second hand Haldex HPP today for my Mk4 R32 and was just wondering a few things.

Firstly is it essential to put a new gasket in when installing the new controller?

Is there a specific torque setting for the bolts?

And is the amount of fluid to come out when removing the old controller going to be need to be replaced?

Thanks heaps guys, appreciate the help.

Always use a new gasket - buy them from VW or Audi - its not a place to have a leak.

11nm + 1/4 turn - buy some new bolts whilst you are at VW - you don't need a tension wrench (as VW advise doing this job with the rear drive unit out of the car) - you need common sense (don't think you will get a tension wrench in).

Depending on the age of your car & mileage (and the last time your Haldex was serviced). If your car has done more than 30,000 km's I would suggest changing the Haldex fluid & filter at the same time. Could save an expensive repair down the track!

A good DIY, if you do change the oil and filter. Note the use of the special filter tool. Access is really limited. I used one to do mine and there would be some strong language required without it.

Thanks for the replys guys. all helpful. The haldex fluid and filter were changed 2500kms ago so no need for that thankfully. Hopefully VW don't charge too much for the parts.

Cheers
