Acc unavailable

[Kalbe]

Hi,

I have the Front Assist Not available on my 2017 Golf MK 7 TDi. It started after by battery died, there has been no bumps as far as i am aware so I believe the radar alignment should still be go
Additionally, following this thread I went into module 13 (Auto Dist. Reg) and under basic settings executed the 'Reset Personalization settings' but got the message 'Not Running'. I did this with the engine running and with just the ignition on. It was not clear to me how to clear the dynamic values so maybe that is all I need if someone can help with that.

Please post an Auto-Scan for better context.

Don't muck about resetting any settings or adaptations. There is a possibility you're going to need the radar unit re-calibrating, which can only be done with the proper workshop hardware.

But, as you've said the battery has failed, I'd look into this first, because a dead or failing battery does cause issues like this where modules are voltage sensitive, and cannot effectively communicate due to voltage drop (which then leads to phantom faults like ACC being unavailable).

Post an autoscan first and see what the forum suggests.

Removed.  Data from a clone/pirate copy of VCDS is not acceptable in Ross-Tech's forum.

Incorrectly positioned sounds like the radar unit mount bracket is knackered, and is a common fault.

Look for Golf Mk7 ACC Radar bracket. Less than £50 for a new one, and if you're lucky, it may not need recalibrating.

Ok thanks, i did check the radar doesn’t look broken i also tried to move it around and its quiet solid with no movement, the battery literally had issues where i had to jump the car a couple of times and i have since had the battery replaced

Tell your friend to update his VCDS as it is a very old version. They may also need to buy a genuine version if the reason its not being updated is that its an illegal clone ?

It is a clone!

Get a better friend, one who isn't a pirate.
