Start/stop, Front assist and ACC errors
« on: 31 March 2026, 19:33 »
Hi Guys,

First post here. Got a mk7 golf 2.0 bluemotion. Recently, on the odd occasion when starting the car it struggles a little to fire up. But the majority of times it is fine. However, when I put my foot down and accelerate quickly it gets a certain point and loses power and shows some of the Start/stop, Front assist and ACC errors.

I can turn the ignition off and start the engine again and they all disappear.

Any ideas what it can be, doesn't look like there is anything wrong with sensor on the front. Would battery issues be a factor?

Thanks
Neil

First thing to do would be to get it scanned for codes.

Too many things could cause these lights and until you get it read for fault codes its pure guesswork as to what could be causing the issues your experiencing.

Had exactly this happen on my daughter's 2.0 diesel Mk7. Garage were a bit flummoxed by codes as couldn't find anything wrong. So we fitted a new battery and no error codes or loss of power for the last 6 months. Clue it was going bad was that start stop wasn't working.
A cheap fix worth trying if your battery is old.

Another reason to turn stop / start off
