Hello
I solving problems with the haldex when parking and turning puts a lot of resistance, I had the flush done in the service now I would like to try to take out the control unit and clean it or replace it
The question is whether some coding is needed when I pull it out and put it back, and also whether it helped anyone
In the case of mounting the second unit, it is probably clear that it will be necessary to code
I am interested in what will be needed and what diagnostics will be needed, will SDD be needed or will I do it with AUTEL? Thanks
for specify i have 08 2.2 with haldex 3

You do not need to recode it if you are just cleaning the current unit. If you are replacing it however, it's a very likely possibility. Just do a search on site for JLR SDD v130 and Mongoose Cable.

wondering what I could use to clean the unit and the connector?

Are you talking about removing and cleaning the electronic control unit on the side of the Haldex. If so why. Is it faulty in some way. Now at the point when I learn something new something old is lost out the other side !
Now retired so it doesn't matter anymore.
Freelander now gone.

You could just use electrical contact cleaner for the connector. As far as the inside of the unit, I have no idea. As it's a printed circuit board there is little you can do. I suppose spraying that with contact cleaner won't do it any harm. If you think it is faulty then you could just send it to that company for testing. Now at the point when I learn something new something old is lost out the other side !
