AUDI A5 S LINE 35 TDI - Auto Hold Dis-engaging

[Aliballibee65]

Evening - I've had my A5 S Line for a few months now and so far enjoying the experience. However recently the "Autohold" has started to disengage without me touch the accelerator.

Usual sequence as an example:

• Approach traffic lights
• Stop and green Autohold engages, green A comes on
• As soon as I take my foot off the brake car immediately restarts and begins to crawl forward
• Have to keep my foot on the brake

This doesn't appear to be a setting in, for instance, driver assist but seems to be something that has possibly failed. Its a real pain, especially on hill starts.

Car is due in Edinburgh Audi shortly for a brake fluid change and if its something that needs to be looked at I can add it to the work sheet.

Any thoughts or previous experience of this issue?

Many thanks, Alan
