VW Audi Haldex Service is Important

Haldex Filter DisassembledRecently while performing a Haldex service I discovered that the local Las Vegas Volkswagen and Audi dealers do not stock the filters or fluids needed to perform this service on your Quattro.

First, I should explain what Haldex is. Per VW’s innovation website:

The Haldex coupling is an electronically controlled multi-plate clutch. On the 4MOTION permanent four-wheel drive system, it enables the propulsive power to be distributed variably between the front and rear wheels. Its continuous adjustment is performed by a control unit that takes slip, handling conditions and drive torque into account.

The Haldex coupling’s action is permanently integrated into the electronic stabilization program ESP and therefore improves the vehicle’s safety.

Second, I would like to explain why it is very important to replace the fluid and filter every 30-40,000 miles. The Haldex system, although impressively functional, has required service intervals due to the amount of friction material that introduced to the fluid during normal use. The filter, a tiny fleece filter will only perform well when it is not clogged with this friction “dust”.  After the filter in no longer efficiently cleaning out the foreign materials then the likelihood of the Haldex Control unit becoming stuck or damaged increases greatly.

So the question is, would you rather perform a $170 service every 30-40,000 miles or replace the Haldex Control unit for nearly $2000? Get the correct service completed at the Las Vegas Car Fixer. We have your fluid and filter in stock and the right tools and knowledge for the job, unlike our local dealers.Haldex Control Unit
