A gearbox oil leak on this Porsche Cayenne had us doing a bit of detective work. We didn’t want to run the vehicle and risk the gearbox running low, so we used the smoke machine to help track down the source.
The culprit? A cracked gearbox heat exchanger, tucked away in a spot that’s about as awkward and inaccessible as they come!
We replaced the heat exchanger and carried out a gearbox service. Thankfully, the gearbox is working perfectly.
