To be fair to yourself Andy, you suggested oils seal failure in your first post, and this was something I very much suspected, but the garage told me they had removed the Haldex and there was no leak. But now I'm not convinced they took the Haldex off. |

[quote="CED"]As a complete novice regarding these matters I feel I must be missing something. All this faffing about filling and draining is not going to be done on the production line. There must be a set amount of oil to add , end of story. Please correct my thinking.[/quote

While the Haldex unit itself is pretty much the same between Volvo/Audi/LandRover etc the differential housing, which is where the fill plug is, is completely different and unique to the Freelander/Evoque, so we don't know how the location of the Freelander fill plug relates to the quantity of fluid in the unit, it may be quite different to a Volvo.

As an aside regarding draining a Haldex in situ. If you remove the ECU from the haldex you can pull out the solenoid control valve. Then if you plug the valve and pump motor back into the now removed ECU and run the engine the Haldex pump will pump the fluid out of the hole where the valve normally is. If all you want to do is a periodic fluid change this is very easy, just two bolts. But of course it doesn't allow you to change or clean any of the filters. |

This may well be a good interim move,
