2006 Audi A4 engine problems

Audi issued a technical service bulletin that I found on your website. This bulletin was regarding the exact parts the dealer (audi) identified as being affected on my car (high pressure fuel pump, cam follower, and corresponding intake camshaft cam lobe). This bulletin (not a recall, but distributed internally to dealerships) clearly states that this is a widespread issue that affected all VIN ranges of specified audi models from 2005-2007 that included mine. Audi extended drivetrain coverage on these vehicles to 10yr/120k mi. This issue causes a worsening loss of power upon accelerating (making driving at all speeds dangerous) and eventual engine failure if left alone. I am the 3rd owner of this car, so I did not receive the intended letter from audi stating the specifics of this coverage extension. My vehicle is currently at ~110k miles at the time of this service (~4-5 days ago). Upon bringing this bulletin to the attention of audi service manager, he did not ask me for the bulletin number or revision, he just denied covering it verbally saying the coverage was "10yr/120k mi, whichever came first" but would not send me a copy of the extension letter proving this. The cost of repairs related to this issue is ~$5,600. I opened a case with audi of america. I provided the requested info, and was still not sent/emailed a copy of this letter, or proof that it was sent to the owner of the vehicle. I was told cases take up to a week to review (they would need me to provide service records for the vehicle, etc). I was called less than 24hrs later that the case was denied, before I provided any info or pled my case that a company with the slogan "truth in engineering" should stand behind an acknowledged engineering flaw. Repairs are ~1.5x the value of the car. I don't have the money to fix this and it creates an unsafe driving condition. Please help.

Audi USA has a know mechanical default with cam shaft and cam followers. As per my mechanic any damage to the cam shaft could be dangerous. Acknowledging this defect 6 years after production audi extended the warranties for this parts to 10 years or 120,000 miles so that they are replaced at first indications of trouble rather then actual mechanical breakage which could be harmful. Audi only notified original owners of the vehicle on record. Since I had bought the are used I was not notified by audi or my local dealership of the known issues with these parts and extended warranties on them. Without knowing about the warranty I had service done on the cam follower twice costing hundreds of dollars. Now the problem is the cam shaft which is going to cost about $4500 to repair. Even though my car has only 91000 miles (less than the 120000 miles required by audi) it is over the 10 year period. I am somewhat dismayed that this was not escalated to be a safety recall by audi so that all owners could have been notified and the part replaced in a timely fashion. I am in a quandary - pay $4500 in repairs which I cannot afford or risk driving with a part that could potentially have a mechanical breakdown that could cause an accident. I think audi has been disingenuous 1. Instead of issuing a recall they disguise it as an extended warranty. 2. They issue the warranty in stealth mode 6 years after manufacturer - no public release or widespread communication 3. They fail to notify owners like myself about 6 pending know issues some of which are critical. 4. When the customer contact them they are failing to honor their responsibility to fix it manufacturer should be held accountable for releasing an unsafe automotive part and then when a clear manufacturing defect is established not issuing a recall and failing to honor warranty claims on technicality.

Air bag warning light is on. This is my daily driver so very concerned. Also this vehicle uses an unusually high amount of oil. I have to add oil weekly to the car. It has been doing this for a long time. I just was informed that I could report this problem.

I have the a4 w/ 3.1 liter v6. Almost immediately after purchase, transmission exhibited bumpy lurching start from stop. Audi diagnose said that's symptomatic of this transmission and engine combination. Nothing could be done to prevent. Within 1st year, the car would stall and completely shut down, necessitating a re-start. Sometimes upon start, and most notably (and the example cited above) when driving at slow speed. (I suspect the stall problems described relates to the lurching transmission problem). On this incident there was no check engine light. Took to audi, they couldn't identify problem. I took to an independent -- they determined problem as fuel pump. Replaced fuel pump. Most recently the car stalled when initiating a left turn from a slow 10-15 MPH roll. As I slightly depressed accelerator, car stalled in middle of left turn -- had to re-start mid-turn to restore power steering and finish turn (turn was down a slight incline so car was able to coast). This happened around 2/15. I took it to audi, the following day. They said because there was no check engine light they couldn't diagnose. I called audi USA -- they offered no solution or database research of problem w/ other audies. A similar occurrence was 8/14 when I exited freeway and as I rolled to a stop, @10-15 MPH the car stalled. Had to be restarted. No check engine light. I may have taken to dealer but don't recall. My concern is the safety risk if this occurs with my wife driving and an oncoming car is unable to stop if the vehicle stalls in similar manner in the middle of a left turn. Could cause serious accident.

Tl* the contact owns a 2006 audi a4. While driving 40 MPH, the vehicle stalled. The contact was unable to restart the vehicle. The vehicle was towed to an independent mechanic to be diagnosed. The failure was diagnosed as a failed fuel pump, a worn intake camshaft, and a faulty camshaft follower. The vehicle was repaired, but the failure recurred. The manufacturer was notified of the failure. The failure mileage was 140,000.

When I drive my car with the headlights on one randomly turns off and then I get a display in the dash that's says "left headlight dipped" this also happens to the right side. I have to turn the knob kn the dashboard on the off position and turn them back on the on position and they start working again. This is ridiculous and unsafe. Please help. Also my engine is burning oil very fast I just had an oil change and drove the car for 80 miles and the dip stick already shows half way full. I had the head gasket and vacuum pump gasket replaced but it still hasn't fixed the problem.

At highway speed, the low oil pressure light came on, before the driver was able to move to the side of the road the engine failed. The car was towed to the audi dealer and after two days the dealer quoted $7000 to start working on the engine. Technician found the timing slipped and valves were damaged. The oil level was fine, but the dealer did not determine why the oil pressure failed. Sounds very similar to class action law suit for a4's through 2005.

On wednesday, april 16th at approximately 5:30 p.m. It was determined by an independent ase certified auto-center in milford, ohio that the engine had good oil pressure however audi stated that there was engine damage. The cam shaft did show wear and would need to be replaced in order to correct the p codes p2293 and p0089 on the hpfp. I then returned that information back to audi dealership ? Audi connection in montgomery, ohio where I spoke with the service manager explaining that they did not see any signs of low oil pressure issues and requested them to honor the internalcampaign on the worn cam shaft/cam follower issue. He then refused to honor my appeal and stated that it did have internal damage due to lackof oil pressure showing no evidence only to refuse to discuss this matter any further with me returning back to his office. Then audi connection did relent weeks later, after stating earlier that they would not perform the work, offering to perform the repairs at a later timeline; a timeline that I could not afford to be without a vehicle and paying on a rental. This particular vehicle type; audi a4 t2.0 quattro 2006 year, make, and model has a history of oil sludge issues and audiusa has had class action lawsuits on such events-below is one similar to mine..."a settlement notice for the vw and audi oil sludge class action lawsuit will be mailed and published in USA today on or before december 29, 2010. The final approval hearing is scheduled for march 11, 2011." since then, while the independent ase certified auto-center in milford, ohio did later discover unrepairable engine damage due to oil sludge issues-known issues to audiusa. I have paid out of pocket over $9,000 on repairs alone that audi knew about, but failed to help in any way...another big business wins again over the common person. I believe that there is more to this issue than we know.

Took the audi a4 quattro to the audi connection of cincinnati dealership for a check engine light (cel) on p codes p2293 & p0089 which indicates a possible cam follower, cam shaft, and/or high pressure fuel pump (hpfp) issues back on thursday morning april 10th, 2014. Later, I spoke with lee at the service desk who stated that the cam shaft was worn and would be a covered item on this internal audi campaign; however, he would not be able to get to it until the next business day since it would take a full day to repair pushing it into friday.I received a call friday april 11th at approximately 11:30 a.m. And it was lee stating that the cam shaft would not be replaced due to an oil pressure issue that damaged both cam shafts and engine. He later stated that the engine would have to be replaced that could cost upwards of $8,000.00. I later suspected oil sludge issues that were also on a recall. Yes, the audi connection did later relent, after stating earlier that they would not perform the work, offering to perform the repairs at a later timeline; a timeline that I could not afford to be without a vehicle and paying on a rental. This particular vehicle; audi a4 t2.0 quattro 2006 year, make, and model has a history of oil sludge issues and audiusa has had class action lawsuits on such events- all anyone has to do is to do their research and locate issues concerning the very issues I too have experienced. Below is one similar to mine... "a settlement notice for the vw and audi oil sludge class action lawsuit will be mailed and published in USA today on or before december 29, 2010. The final approval hearing is scheduled for march 11, 2011."
