Haldex Filters and Oil
Hi
The Haldex unit needs to be serviced on a regular basis.
I think that later Volvo`s use the Haldex Gen V5 and there is no filter therefore requires a more frequent service about 12 to 15k.
Its quite easy on this model as there is no filter just undo the pump and let the oil drain out, there is a small plastic gauze that needs to be cleaned.
On older models they have the Haldex Gen V4 this does have a filter and it is a little harder to remove the haldex pump,it also requires a new filter.The service can be left a little longer about every 40k but care is needed when refilling the Haldex as about 70ml needs to be removed after filling.
If you use your car for heavier work such as caravan towing the Haldex works harder.
This is only my opinion about Haldex but I believe prevention is better that cure.
There is also a good video on youtube that clearly shows both the 4 & 5 being serviced.
There is a guy in Kidderminster who offers a drive in Haldex service for £180 including VAT.
