Don't forget to check fluid level, especially if light still trips with ESP off.

 

Will do

 

Possibly.

And if it IS an ESP problem, acceleration tripping it could point to EDL (rear electronic differential lock), which is aided by the spinning tire being braked individually...which could be hindered by a failing ABS sensor (or something else) at that corner.
That's just a guess.

Another possible cause is usually tripped during braking....failing EBD (electronic brake pressure distribution) preventing overbraking of rear wheels before ABS kicks in.

Some of this depends on specific ESP system in your model...more than one have been used in different models (don't know years/model?) with same functions, but different warning patterns. If problem persists, you need a code read by Vag.com.

 

Just wanted to follow up with the thread. Strangely I cannot repeat the issue. I'll post back if I can get it to happen again.

 

Did you top off your fluid and now you cant repeat the issue? Or did it just randomly stop happening.

I have an 04 that is doing the same thing. I havn't gotten to adding more brake fluid yet so I'm not sure what will happen.

 

Did you figure out the solution?

I have exactly the same problem in my '05 A8 W12. When I accelerate hard the brake warning light flashes and beeps in the secondary MMI display, and the brake warning light in the speedo comes on. Stops as soon as I throttle back.

Regarding brake fluid, I have not had a service recently so have not tried it.

I have not solved it, wish I did.

I had originally reported I couldnt repeat the issue, but I do now still occasionally get the same behavior I originally reported and you also report.

 

I have the same issue on my 04 A8L. Anyone run the Vagcom on this? I will be ordering mine soon so until it arrives, if there is any new info on this, please post it.

Thanks.

 

Top off the brake fluid. The red "BRAKE" light is for fluid level low warning. It beeps and flashes to get your attention. The ESP/ABS will disable itself if it sees low fluid constantly, only as a default. Also, good idea to have a look at your brake pads. As they wear and the pistons are further extended, the brake fluid level drops in the reservoir.

 

I can confirm aspen79's post. I topped up the brake fluid (although had trouble seeing whether it was low or not) and the problem vanished.
