Planning to do the waterpump on my 13' x3, since I don't know if this has been done in the past. 110 000km (69000 miles)
[Q] What's the faillure rate of the thermostat?
This thermostat is 290$ on rockauto, seems a bit high.
[Q2] Is the diverter valve should be changed in the same time?
I own a audi A4, and those diverter (same design has the N55) are failling around 60 000miles (rubber membrane). I've updated it with the GFB DV+.
The thermostat also failing around 60 000 mile on my A4, but it's 60$ and take about 1.5h to change...
here the x3, blue ext, chessnutbrown int, almost full equiped (all pack but dynamic, no nav, no head light washer. that's it)
