Superb 2.0 diesel dsg 170 2014

I have the car 4 weeks now and have experienced 4 power surges (best way I can explain it) they happened while going slow in heavy traffic or going around a roundabout. It was just instant power/acceleration the car took off for no apparent reason.

I brought it back to the main dealer explaining what had happened and it's rather dangerous and he said he's never heard of that problem before if it happens again to bring the car back.

It'll be a bit late then when the car is stuck up the arse of another car or worse has hit someone! Anyone any feed back on this or experienced it in there own car??

Who has never heard of it before, Someone at the Sales, Service Desk or a Qualified Master Tech from the Workshop?

 

Best get the Master Tech to put in writing that the car is performing as can be expected and is safe to drive after he / she has had it on the Diagnostics & then out for a road test.

Cruise contol issue as you hit 19mph? Try leaving cruise contol switched off for a while

 

Silly question - are your brake lights working OK?

He asked me was I using cruise control when it happened, I was not, I've only used it once on at 120kms. The brake lights are working correct how would this affect it (not been smart asking) 

It's a wierd 1 cause it just randomly happens

Not the anti stall kicking in was it?

Under circumstances cruise control can "resume" especially when starting to pick speed up again after being below 19mph (cruise doesn't operate at very low speeds) - so trying to get car back up to speed . Make sure cruise if full switched/clicked off on the stalk

 

The brake light switch is part of the cruise control mechanism and it can get very confused if faulty 

 

A least cruise control systems are better than a few years ago. I had a hire 2.8 auto Granada Scorpio that after emerging from motoway heavy traffic suddenly decided to get you back up to the high cruising speed from before the traffic  - it dropped two gears and floored the throttle with no input from the driver!!!!

In D, when the speed drops low enough, the car will roll along at idle in a low gear (1st/2nd). When the car stops slowing down it can feel like a surge since there's a positive change in acceleration. In a manual, you'd probably be pushing in the clutch under these conditions.

 

It may also be the 'box hunting between gears at low speed. In D mode, it tries to hold onto the highest gear it can but at certain speeds this results between a lot of shifting up and down. S mode is better under these conditions because it holds gears a bit longer.

Any noises? -  Possible DMF issue?
