2 lts TDI FR 25000 miles
I also get loss of power at any speed but around 2000rpm, do not know if it the CAT regenerating ( DPF ) as this has happened after long journeys on motorways doing 70mph so not sure, as NO warning light comes on.
Not sure if it’s a calibration issue?
Or possible Turbo wastegate sticking or EGR sticking.
Car going in for service tomorrow so will ask them too.
