#ABS doesn't work. I decided to disassemble my ABS block on my # w202 #mercedes, in order to finally understand what is the reason that it has been slowing down the wheels for 4 years from the date of purchase! The reason for the breakdown turned out to be so brnal and predictable for a car from the 90s, namely the control plus contact sealed off from vibrations and temperature drops. As a result, the repair took 5 minutes and now the ABS works like a clock!
