Question about Volkswagen Cars & Trucks
VW LT 35............the preheat warning light begins to flash after 20 seconds of starting the motor. No problem with the headlights, brake lights etc. The motor runs without problems. What could be causing this? Thank you

Check the wires that are going to the brake pad sensors.Some shops will install pads that don't have the sensor connections on them, causing this light to stay lit.

Check and see if your alternator is charging
Low voltage will cause those lights to come on, as the computer is shutting down.
To check your alternator you will need a volt meter... WITH the engine running you should have about 14 volts coming out. IF NOT you need to replace the Alternator!

The brake pads have sensors in them, when the pads get worn down to the sensor the light comes on letting you know its time to replace. this happens well before the pads are completely gone to reduce wear on the rotors. You should have the brakes replaced and the sensor also.

Do the ABS brakes function? If not, there is a fault with a wheel sensor or the ABS controller. Check the OBD Codes. You can get them scanned at Auto Zone for free. If there is no communication from the ABS control unit, that's probably bad and needs to get rebuilt. Cost about $150.00 if you send in your unit.

SOURCE: mk1 A4 ABS warning light
I have a 2000 Audi A4 and the break wear sensor warning light come on for me too. It does not flash and is orange in color. I have asked the Audi dealer twice about it and they told me it's because the previous owner put aftermarket break pads on it, thus messing up the sensors. I don't know about the ABS warning and other than that I wish you luck on it.
