It's been said above, but my very first thought was adjust the brake pedal switch.

You can monitor it with VCDS and see just how "hair trigger" the 2 separate sensors are.

I adjusted mine, but it still occasionally does the same thing. Next time I have all the gubbins out of there I'll give it another turn or two.
Sadly that will probably be fairly soon as I have an issue with my DVB-T wiring which is all buried in the same area, behind the drivers knee panel.

Basically there are two switches in one with very slight difference in the operating position. One works the brakes lights, the other informs the ECUs.
It is very possible to have the pedal released, brake light off, no braking force BUT the ECUs are still being told the brakes are on, with strange sluggish behaviour the result until some minor jolt or vibration regularises everything.
It is of course not a fault, just normal operation, so nothing gets recorded.

Thanks for the response everyone.

I think we can bring this post to a close at this point.

I have altered my driving technique this last month or so and have had no further occurrences. I did purposely hit the throttle on one occasion slightly before releasing the brake and the slow acceleration was replicated.

Perhaps the brake switch may be a little sensitive and need adjusting but at the moment I'll just carry on as I am and monitor the situation.

Thanks for all your support.
