2006 Audi A4: check engine light

Filed Sep 11, 2015 · Electrical, Engine · 12,000 miles · CA

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.

I have an audi a4 2006 that I purchaced as a certified pre-owned vehicle. Shortly after in november 2009 I received a recall from audi of america "upcoming voluntary emissions service action 28f2/ji ignition coil inspection replacement"'. At the time I wasn't having any problems but took the car to dealer where I purchased it and had the coils checked. Almost immediately after leaving the check engine light came on and I went straight back to have it checked. There was never anything ''wrong"' so I couldn't trust the check engine light. This seemed to become a routine whenever I went to the dealer the check engine light was surely to come on. So much so that I stopped going to that dealer for servicing, its not uncommon to hear that women that go to get their car serviced get "special'' treatment. I am always skeptical of that. Now I have 60,000 miles on my car and after experiencing severe shaking and the engine light coming on and blinking one of the items that arose again was the coils replaced for $424.22 a misfire cyl 4 caused by ignition coil misfire in cyl 4. Apparently the recall "'is over" that was the detailed and thoughtful explanation I was given by the representative from new country audi in greenwich, ct. I don't understand how a recall could ever be over as it will be unsafe and costly to the customer for the life of the vehicle.

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."

Purchased the vehicle in march 2012. Approximately 4 months later the "check engine " light came on . Had the codes checked and main code came back p0722 which directed me to a "dealership only" repair. It was told to me that the TCM was bad and needed replacing. I find out audi initially used a faulty plastic part that they were aware of would fail. I called audi USA for assistance and they worked out a 15% discount with the dealership and no assistance from audi USA. I informed them that I still feel very strongly that if this is a continuing problem with audi transmissions then they should cover full cost of this problem.

I have had a continuing problems with my 2006 audi a4 quattro 2.0 with acceleration while pulling out unto a highway. The vehicle bogs down in front of traffic oncoming traffic. My private mechanic provided me a bulletin on the problem. The audi dealer has failed to acknowledge a technical service bulletin regarding abnormal camshaft wear and failure with the standard stock factory installed pumps which are from a design flaw. The company has refused to take corrective action. The federal safety agency has three items#10024427, 10030593 and 10025965 regarding issues with the fuel system. In checking online with a google search, it appears many 2004-06 audi's have the same issue which create a danger to the driving public. The tsb is not making audi look into the problem and I feel many consumers are planning to make repairs for audi's design flaw including their cover-up of the design flaw. It is critical that this issue be investigated before someone is seriously injured. The consumer stated the check engine light has been on for the majority of the time he has owned the vehicle due to problems with the fuel system and or the ignition coils. Numerous times, the vehicle has failed to accelerate properly. The vehicle was taken to the dealer and upon inspection the technician noted an oil pressure issue involving the cylinder head, bearings and short block. The consumer believed the additional problems were due to a defective camshaft.

Car did not show any signs prior to check engine light coming on. Within several minutes of check in light appearing the car begin driving rough and smoke poured from under the hood. My husband quickly cut the wires of the coil pack from the housing to prevent the fire from spreading, as I grabbed the fire extinguisher.
