Hi all, recently i've been getting the brake light switch almost everytime i go WOT from standstill or low speed (<20mph).

I searched the archives and found mostly references to the brake switch or the speed sensors.

I'll soon be bringing the car ('01 S8) to the dealer for that transmission cable recall, should I simply ask to "check/adjust the brake switch". Or is it something a layman (i did a TB job in 3 weeks...) can do himself?

Thanks for any advice!

Not an expert, but it sounds like wheel sensors could use some cleaning/adjusting.

If you're on the minimum mark and it goes unlevel in hard acceleration, the sensor might fire.

Not up on my S8 warning signals, but is that the same one as for the hydraulic boost system? In earlier V8s, if you are a little low there, that red warning light will go on in the same circumstance.

What light is going on? The red "brake" light that illuminates when pulling the parking brake?

Check the front brake pads

Checking the brake fluid level seems a good idea.

and the pads are fairly new.

is has to take up the space of the worn brake material.That is why the light COULD come on.Either way its a sealed system, if theres a leak you'll know it.

I've been having this problem as well and can confirm its the brake fluid.

Glad its solved, this was driving me crazy.
