I had the same issue with corrosion on the dampners. They aren’t expensive from partsouq or equivalent.
I am a big fan of AHC as I do only very occasional off road and the comfort is hard to beat. Properly maintained the AHC is very reliable.
It is strange. Usually the frame is attached first and unibody is clean.
It does look like it has been coated with something (my unibody is same colour as rest of the bodywork) as it appears black.
Is it just these two spots ? How is the rest...
Is that the same sensor across the two front and the back ?
My AHC has been acting funny last weekend. Deciding to stop working after a 2 month hibernation. Next day normal service was resumed but I decided to change the 3 sensors and the AHC...
