A Haldex oil change going really wrong...

Hi,

If some of you intend to DIY their Haldex oil change. I've made this "How to guide":

I had willingly not mentioned the drain plug of the rear diff to avoid this kind of disaster as shown in the video below.

Both drain screws of Haldex and rear differential are unfortunately the same and close one to each other, indeed.

Thus be really careful on what you're doing.

This video is really interesting in its last third in particular, because it shows all damages on a differential, that has be driven for 9000 miles without oil in. As said in this video, this a DIY fail, that finally leads to huge expenses.

If you nevertheless do this mistake, 2 things should warn you, you're on the wrong way:

1) When you remove the Haldex pump to clean the strainer, you'll finally see an important amount of oil flushing, just because, you're actually draining the whole Haldex which was still... full of oil.

2) If you don't remove the Haldex pump, Oil will almost overflow instantly and you'll be able to fill a very small quantity of oil. And there's a good reason for that. Of course you've drained... But you've drained the rear diff instead of the Haldex!

Well, better look twice, or the bill may be very steep!

Take care buddies!
