Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2001 Audi A4 1.8 turbo at 99.1K miles. The timing belt prematurely napped while the car was traveling in a busy morning commute causing car to disabled on the freeway. The timing belt failure caused extensive, additional damage to the engine that estimated to coast about $6000 to repair. I have all my maintenances done at the Audi dealers and follow all the recommend service by Audi. I was never been recommended to replace the timing belt on my all previous visits for maintenance service. The recommended timing belts replacement by Audi for my model is 105K miles. Both Audi dealer and Audi denied been in responsible for the timing belt defect and/or incorrect timing belt maintenance recommendation which subsequently result the engine damage and provide any assistant. According to Audi, they do not guarantee the timing belt will last to 105K miles, only that it is their recommendation.

2001 Audi A4 1.8 turbo: The timing belt broke while the car was traveling in heavy, rush hour traffic causing the car to be immediately disabled and stopped with no opportunity to move the car off of the highway. The 3-lane highway was backed up for 6 miles while police and emergency workers worked to tow the car. The disabled car led to a very dangerous situation with traffic backed up for over 1-hour on a 3-lane highway with a 55 mph speed limit and could have easily caused additional accidents. The timing belt failure caused extensive, additional damage to the engine that is estimated to cost about $5,000-$6,000 to repair. My Audi A4 has the same 1.8 T engine and item (timing belt) as in the 2001 VW 1.8 T and that item has been recalled. The timing belt defect in the 2001 A4 appears to be quite well known to the two Audi dealers that I frequent. Since I bring my Audi in for service at the regular intervals - and since the timing belt issue is well known to Audi - I would have expected the Audi dealers to bring this issue to my attention so that we could have replaced the belt as part of regular preventive maintenance. The fact that this well known problem was not handled in preventive maintenance led to a very dangerous traffic incident and caused extensive damage to the vehicle's engine.

: the contact stated while driving 50 mph on the interstate, there was a popping noise from the engine compartment followed by a lost of all power. The contact managed to pull over without incident. The engine would not restart and the vehicle was towed to the dealer for inspection. The dealer determined there was a hole in the engine and was unable to identify what caused the hole, however a new engine replacement was necessary. Updated 5/10/2006 -

A4's have a poorly designed cam tensioner that eventually leaks oil. The cost to repair the item is approximately $1000. The dealer (carousel Audi) even admits to the fact that it is a poor design and there have been numerous complaints about it at the dealer. I've also read numerous complaints about it on Audi forums. The leak typically found shortly after the warranty period has expired. I feel strongly that this should be a recall on all respective cars to have it repaired!

'01 A4 2.8: (1) digital display is blurry and cannot fully understand everything the computer is displaying, (2) internal oil seals have become defective causing a foul burnt-oil smell within and outside the vehicle, (3) transmission downshifts very hard and rough, (4) very poor design by the engineers to place a cupholder directly over the stereo and heater instrumentation which have caused my buttons to stick. Have taken the vehicle to various dealerships and shops and technicians have stated that the seals are obviously a design flaw and so is the display panel with has some software or lcd problems associated with it.

Oil light came on. Immediately pulled over and checked engine oil level. Not low. Took the car to the dealership. Originally diagnosed as needing a new oil pump due to oil sludge. On further inspection the dealer found scarring on the engine bearings and wear on the camshaft. Upon flushing all the pre-existing oil out of the engine, metal filings were found. New diagnosis: Completely new engine required. Audi, usa knows this is a prombem with A4 1.8T. They've extended warranties as a direct result. Yet becuase I'm the second owner and can't produce all previous oil change receipts, I'm being required to pay for the new engine. This is a poor engine design that I shouldn't be held liable for.
