My daughter attended TireRack's "street survival" program today. Sponsored by BMW club, it was really great. This is just a confidence builder designed for younger drivers, on a closed course.
Lots of slalom sections with cones, a traffic light for change of direction reaction, and a water pad for turning and straight line stopping. Students were encouraged to drive at their own limit, and you should have seen all of the smiling faces!!!

Problem:
During my daughter's 4th or 5th straight line stop in the wet, the front wheels locked up. The ABS light and tracks light came on. For the rest of the session, no ABS or tracks, which made things even more fun!
When I got home, I found 2 codes:
1-4-2 Faulty brake lamp switch
4-4-2 Pump pressure low

The brake lights work great, even though they got a work out today. I didn't try cruise control.
The pump pressure is low? There is plenty of brake fluid, does this mean that I will need a new ABS pump? Bummer.

The car and I are going to rest. I will re-check in the AM. I was on my feet all day chasing cones in the hot sun.

Thanks,
Klaus

Please answer your responses. We need to know if the advice is good or bad. The 164 has a new home, all I am left with are 2 turbos :)

I looked it all up in my trusty Haynes manual? The position switch will be easy, but replacing the ABS pump is out of my league. The dealer is going to love me!

I can't answer teh question about teh pump, but my '94 has a continual problem with the lsiding contacts in the center brake light. It'll not light for a while, yet within a few more stops, it works again. Id was hard to find. Cleaning the contacts and using bulb grease on them helps some, but next time I'll probably hard wire the connection.

In my case, the lamp failure indicator lights, was she aware of the lamp failure light coming on? Could you simply have dirty connections in the ABS wiring?

I finally got to the dealer today. $1800 for a new pump!!! I told them to forget it, the car is only worth 5K.
Guess what? On the way home, leaving the dealership, the ABS light turned off! And it is good to go. I love self-fixing things :)

Probably got copious amounts of water in the area from sliding on the wet skid pad and it took a long time to dry out? Who knows. The ABS does work again.
