Occasionally when towing bigger trailers (1.5-2.5T), I very intermittently experience odd behavior, most obvious being like the car becomes speed restricted to 80-90km/h, overdrive seems to not work for a period. I swear its due to the auto transmission overheating but I have no way to tell for sure and am curious if it could be something else like high intake temperatures causing fuel reduction from the ECU or something. My EGTs and Coolant temps are always well in the safe zone when this occurs. It usually happens when driving in warmer weather but that may just coincide with when we go away on long drives/holidays. I do run 16-18psi boost so my intake temps are running a bit high (about 50-60 deg C above ambient) and I thought on our last trip maybe it was when the intake temps were hitting 80 deg C, the problem was occurring but it was too hard to tell for sure as there were other things at play too i.e. strong winds
Anyone else experience such things?
