Good Morning people.
I've been looking around for a couple of days for a problem similar to mine but unable to find one. I believe the S1 uses a 60/40 split instead of the usual 100/0 untill the front slips then engages. My issue is if I reverse and then come back to the car a bit later, when I start to set off I get a small thud from the rear diff after a couple of meters as if the haldex is engaging late. The 4wd works when driving 100%. No issues or wierd noises when driving or when lifting off then throttling back on. If I park up without turning the car off...reverse out of a spot for example then set off the noise is not there, only after turning the car off.
The haldex oil was changed about 15/20k back but doubt they checked the mesh filter on the pump so I have reason to believe it may be clogged or something. I will be dropping the oil,.checking the pump and replacing the o rings along with filling with fresh oil this weekend. I have OBDEleven and have seen threads stating you should use the pump reset function after doing this. Has anyone else experienced something similar? I doubt it's a bush or a UJ as it's only there after turning the car off. Many thanks for any suggestions or opinions.
