Brake Assist Error

[olehholy]

I was wondering if anyone else with a 2002 E430 4-Matic exprienced the following problem. While driving, the ABS, Barke Assist and ESP error lights all go on at the same time resulting in 3 Malfunctions. The next time I start it, it all goes away for about 2 weeks and then back again.

Do those 3 systems all share some common sensor(s) that may be intermitently malfunctioning, or is this another case of:

"sir, you need to replace a 'computer' again.

Many Thanks,
