What do we need to know about Gen 5 Haldex servicing? It is slightly different to the Gen 1-4 servicing! The Gen 5 Haldex systems do not have a filter which needs to be replaced. Instead they have a gauze filter within the pump which filters out the debris. This debris is created via the mechanics of the Haldex and all wheel drive system.
Issues arrive when a Haldex service is carried out and the gauze filter is not cleaned as well as the pump! The pump needs to be removed and both parts cleaned to get rid of the grit and debris before filling with the clean Haldex oil!
We recommend every 20,000 miles for Gen 5 Haldex servicing. This vehicle on the images had its service carried out at 32,000 miles and the oil was full of metal fillings and the gauze filter was completely full, practically impossible for the Haldex oil to get through to the pump. As a result of the service being carried out 12,000 miles after it should have, the Haldex coupling has deteriorated in its abilty to work as it should. If the Haldex unit fails the vehicle will only work as a 2-wheel drive vehicle. This is a pricey repair and can be avoided if only sticking to regular servicing intervals!
Are there products to help limit the amount of swarf in the Haldex?
There are performance parts you can use to help limit the amount of metal fillings being pulled towards the pump. One of which is a Racingline magnetic Haldex sump plug! This Haldex plug will attract the fillings towards the plug as apposed to the pump filter. You can find out more information on the plug here. We carry these in stock, just ask to upgrade on your next Haldex service!
