A4 vw bew tdi brake booster vacuum hose updated part# 1j0 612 041 fd vw part numbers 1j0 612 041 n and 1j0 612 041 fd. These hose are known for cracking at the plastic tube causing low vacuum; poor / inconsistant braking performance. This could lead to crashes, injuries, and loss of life. These hoses were recalled in the uk, but not in USA for unknown reasons. Vaico is the oem supplier of these hoses, and were most likely fitted to all bew tdi m/t mk4 vw vehicles sold world wide.
There is a failure with the computer system in the car causing the car to break even though foot is on the gas pedal. This causes the car to loose speed and I am unable to make the car accelerate until the car is placed in a lower gear. Very hazardous in atlanta traffic. I have spoken to a vw dealership service department and they have agreed to fix the problem, but waited to make NHTSA aware of the issue.
