Hi it's an auto thanks

Hi guys, if I sit on motorway at say 50 mph the revs fluctuate slightly, it also, upon gently throttle, seem tobe a bit under powered but if you need it to fly it will seems a strange one I know. Done 159k well looked after and serviced regular. Took it to an Indy and he gave me a list of faults 6 glow plugs and 2 thermostats were the main issues as he thought it was a dpf fault, back pressure was a lot higher I think. Any help appreciated cheers De

Hi all, had my tourer now for 2 years and it's great 159k on the clock but feels like new still. Only prob I have is at set speed the revs fluctuate up n down only a niggley prob but still I like it resolved. Is it engine fault or gearbox. Cheers guys
