Possibly over boosting caused 'limp' mode to kick in. Prevents engine damage from overboost but resets when you turn ignition off/on.

I'm sure overboosting would throw a code so I think hooking it up to VAG-COM would be a good idea.

If the rev's were still rising yet you were getting no power, could it not be a slipping clutch? Has the symptoms of one.

One of the girls at work has exactly the same fault on hers. Posted this on engine forum. She'd get to 75-80mph and turbo cuts out. She then has to restart it to get turbo working again. Dealer couldn't find a fault on two occasions & wouldn't take it over 70mph. Replaced intercooler hose but still doing it. To this date after three visits still has fault. [:(]

i would go with the limp mode myself. it sounds like the car needed more power to make the hill and overboosted and limp mode kicked in.

sounds very simiar to my thread and whats happened to me lately!!! i put my foot down and the car went into limp mode... turbo would not engage at all in any gear or at any speed and wouldnt go over 70 mph and would not rev any higher than 2300 rpm!!!

no idea whats wrong but i turned it off got out... walked around car got back in and car worked fine!!!!!

very frustrating!!! im going to replace my MAF this weekend!!! no messing about the garage who deals with my warranty company told me that he could check it and still wont find anything and you will be ?35-40 out of pocket.... but he then said ive two passats with similar problems in the last week or so none of them threw up any codes but we changed the MAF and it has sorted it!!!
