Electronic Parking Brake and ACC fault

Post by TM2019 » Fri Aug 07, 2020 6:24 pm

Fault occurred 3 weeks ago eventually got in to our local dealer as no loan cars available until this week.
Car was in 2 days due to new switch required.
Partner drove home within 15mins, fault reoccurred.
Rang local dealer service dept as needed the car to go away this weekend, car booked back in today.
Partner waited 3 hours for the car and still not resolved.
Now being told no appointments available now till 18th August and booked in for a further 2 days and no loan car available.
Not happy :-( :-(

What are the fault symptoms you are experiencing ?

Not aware of how the parking brake would be related to the ACC. Is it 2 separate faults you have ?

The electric parking brake is mentioned in the ACC control module so must have some input or might be operated by that module?

Only a suggestion but if there is a brake fault the ACC won’t activate .
ACC needs control of the braking system to slow the car down when nessesary so if there is a brake fault the ACC identifies it and will override any commands from the driver.
So ACC is doing its job and probably not faulty.
Poor from VW they should prioritise braking problems and know how to fix their own cars first time.

I’d understand if it was a footbrake problem but I’m not sure why the handbrake has anything to do with it. I suppose if you don’t use Auto Hold but you do use ACC and it came to a complete stop behind another car, it may need to apply the handbrake rather than keeping the footbrake held. So maybe it’s just being cautious and only allowing ACC to work if all possible scenarios are covered.

Used to have a fiat bravo many moons ago and they were willing to give me a car everytime but I had to pay for the insurance £21 be it for one day or seven, needless to say I didn't take it.
Possibly a deliberate ploy at that time?
