Intermittent brake fault

[Richard van der Hoff]

Hi folks,

Since we've been on the topic of intermittent fault indicators this 
week, here's another one:

Patient is a 1999 (B5) S4. Three or four times lately the big flashing 
red brake fault indicator has come up on the driver information display. 
It flashes away for a few secods, and then stops. I've checked the fluid 
level (which seems to be fine) and have hooked up the VAG-COM (no stored 
codes), but haven't really looked much further (it's a bit cold to be 
poking around tbh...)

The brakes seem fine, but obviously having the big red warning coming on 
is a bit worrying. Any suggestions as to things to check?

Thanks

Richard
