Hi my T5 occasionally goes into what I think is limp mode, loss of power, and won't do more than about 30ks.
Usually its when I'm either on the highway, normally on cruise, and have to hit the brakes or change down, eg a kangaroo hops onto rd. Or Ive been going up a steep windy rd and it just happens.
Spoke to my mechanic about it, who hooked it up to the computer with no show of limp mode. He offered no other advice!!

Its not a regular occurrence but once is enough. Pulling over and turning off the engine fixes it,
Any advice would be appreciated.
