Title: Tdi STOP brake fluid - Fluid level is ok ? :S
Post by: jonnyb on 06 December 2013, 16:50

My mk4 1.9 tdi (ALH) has recently started flashing the STOP warning saying brake fluid. Naturally I checked the reservoir and it's at optimum level.

This has only happened a few times when doing a fast 3 point turn although this morning flashed instantly when starting the car. It was cold if that's possibly a factor.

As it's very infrequent am I looking at a sensor flickering on/off or could it be something else?

Pull the connector from the brake fluid level sensor. Then turn ignition on, the brake fluid warning should now appear, also you will see the (!) symbol light up... Now short out the two contacts in the connector (obviously the part with the cable attached, not on the sensor) - the light should go off. If it does the level sensor is broken, if it still is light up this would indicate a wiring issue, or an internal fault in the speedo cluster. This can also be tested, just check with shorting first and post result.
