Gen 4 / Gen 5 Haldex fault
Here in the workshop we are seeing more and more issues with the newer style Haldex 4 wheel drive systems on the VAG range. The newer gen 4 and gen 5 systems no longer use a serviceable filter, unlike the predecessors. They now have a small gauze located on the back of the pump that is not recognised by VW/Audi to be inspected at the time of service. We recommend the pump is removed and the plastic gauze cleaned which should prevent the pump from burning out due to the blockage.

00448 – Haldex Clutch Pump (V181) – 011 – Open Circuit – Intermittent
01155 – Clutch – 003 – Mechanical Failure – Intermittent
02248 – Valve for Controlling Clutch Operating Angle (N373) – 014 Defective – Intermittent
The repair ultimately requires the replacement of the pump itself part alone costing around £225+vat. At the same time is good practice to change the Haldex oil and clean out the cavity the pump sits in.

VW Golf 4 Motion R32, GTi, R32, Tiguan, Sharan, Passat

Recommendations to avoid would be to simply factor in the removal of the pump at the time of service. And service more regularly especially on the latest gen 5 systems. 20,000 miles is a more realistic figure compared to the manufacturer recommendation of every 40,000.
