Engine cut out just this side of 100mph? HELP!
 

Good afternoon,

Let me start out by saying hello, I purchased a 06' A4 2.0 for the wifey back in December (that's what she thinks anyway!). I've been lurkin' from time to time and have learned alot and got some good tips. I just had my 1st issue and I wanted some advice/ideas before I contact the stealership.

So, we took a short road trip this holiday weekend and yesterday on the ride home about 30mins into a 3hr ride... I see a clear flat patch of interstate and hit it! right around 100mph I felt a little like click, or bump in the gas pedal (I don't know if that makes sense)... Seemed kinda like in other cars I've owned when your almost all the way to the floor you push a little harder for passing gear.

Well, the car started slowing down... I backed off the pedal and went for it again... As I was pressing the pedal to accelerate I could see the RPM's reving up but, I was still just coasting and losing speed. I tried nudgin' it into nuetral and then back in D, no go. Finally, at about 60mph it seemed to regain it's power/re-engage... After a few minutes I tried it again and the same thing happened. I'm no spped racer but, have had the car well over 100mph before with no issue. I basically didn't try my luck any harder as I didn't want to be on the side of the road. Everything else seemed to work fine. The cruise was on but not set the 1st attempt, it was off altogether the 2nd attempt.

Sorry for the long winded post but, I'm a little freaked, thinking it's NOT good. I would appreceiate any advice, especially from anyone that has had the same or simuliar problem. Thanks in advance.

Regards,
Jason

P.S. - I'll post up some pics of the ride this evening, I didn't have any on the work computer! Thanks again.

This used to happen to me and nobody knew what it was for 8 months.
Turned out the cam shaft needed to be replaced. Was replaced about a month ago and has cleared up. The issue was a know issue by Audi and covered under warranty. Call Denny Dong at Audi in Mission Viejo California and ask him about my STaSIS A4 if you need information to take back to your dealer. This drove me crazy for 8 and was intermittent and scary! So glad its sorted out.

Dude, thanks so much! We dropped it at the Audi dealership here in Dallas and we should get a call sometime today. I'll see what they say about it and if they don't know I'll definitely call your guy!

Thanks Again,
Jason

I took my A4 to the University Park Audi here in Dallas and they called me yesterday to let me know what the deal is... I have to talk to him again and get the particulars. Basically he lost me at "about $2500.00 in parts plus about that much in labor"!!! After that he might as well have been speaking German cause my brain just locked up! LOL :)

If I remember at all wanna say it was a turbo inlet and, caused a cam to go as well? We purchased a platnium warranty that covers alot including the turbo but, they are having an adjuster come out from the warranty company to look it over. I'll find out what they cover and don't sometime today. There were a few other things some I can fix or can wait but, overall feel like I got burned on my 1st Audi... 06' 51k miles only had since December and it's got upwards of $6k in repairs needed! I HOPE I'll be glad I purchased the warranty but, I'm affraid they will wiggle out of it somehow.

I'll let ya know what happens.
Jason

This is a really interesting, yet bizzare issue...double check with a dealer what has led up to such diagnosis...There should have been a trouble code stored due to possibility of PCM instability...If it would be camshaft I'm positive there would be much more driving issues than just flooring it to 100 mph
Best of luck...

I'll try to get more info out of him today... My brain literally went to jello after I heard $5K! I stopped writting and could barely stand to listen.

I do remember he mentioned there was a "stored code" that led them to the diagnosis. I also distintly remember the word cam but, didn't think it was the cam shaft in the engine? Are there some dort of cams in the turbo? I'm guessing at this point... I'll post up when I get the details.

I went with NAC (national auto care) for the warranty and got the platnium coverage so the turbo and more electronics would be covered for something just like this... But, I still cant help but to worry they will try to get out of it and I'll be left holding the tab!

Thanks,
Jason

UPDATE:

The warranty is paying!!!

I read something about the B7's having bad fuel pumps I'm wondering if this has to do with that? Anyway they are replacing the boost recirculation valve, intake cam, and high pressure fuel pump and, replacing the fuel sending unit.

The "claim" had LCD screen which was running it up to the $5k. looks like parts labor the warranty companie is going to be on the hook for about $3400 or so...

I'm paying $50!!! BUY AN EXTENDED WARRANTY!!!! :) Hell, they even waive the $140 they charged to diagnois it. I LOVE my Audi, even if it is broke!

Jason

wow!
 

Wow, stories like that are why I dont have an Audi and probably wont be getting one. Why fuck would you drop as much as these cars are with FULL KNOWLEDGE that stories like yours are commonplace? Who here can afford to drive around in a car that has a friggin $5000 bill just a mile or two down the road.
Buy the extended warranty--ha! What a pile--when you have to buy a warranty just to enjoy your car without worries--is that how all the guys on this forum have to live? Do people wake up in cold sweats around here with nightmares of failed components and $5000 repair bills!!?
I think I am just gonna buy a Bimmer or Porsche.

Is whoIi had through the Dodge dealer for my truck... good company.

Ok.. be prepared for the same type of shit.... Remember, a Porsche is made by the Same Company, and BMW's reliablity is no better, but both cost more to fix.

same things?
 

I could see the Porsche being more expensive, but on the BMW I am not so sure.
And you know whats funny--look at the true delta ratings for BMW's and Audi's--you'll see the AUDI's get RED LIGHTS--meaning shit reliability year after year Why cant Audi engineer a vehicle that will last? Look at the BMW's--MUCH BETTER reliability. Look around you on the road----how many used BMW's do you see around you--hint---they're everywhere. When's the last time you saw a pre 1996 Audi on the road?

From what I can gather the Audi looks nicer--perhaps a nicer interior. I guess I am not willing to spend huge amounts of cash on constant issues and worry about the threat of catastrophic breakdown.

I wonder how many people get the Audi bug--hoping and preying that wont get screwed on their car and then walk away over sheer frustration THOUSANDS later, thinking damn--wTF was I thinking there--I knew the risks. Oh well, at least it was a cool looking car.

What a shame...........

when your "bimmer" or porsche break it will be just as expensive. It's an awesome and I was indeed armed with the knowledge that if it breaks it's expensive. I.E. - The warranty!

I just purchased a 2006 A4. During my test drive at a dealer, I noticed something similar. I accelerated onto a freeway ~85 mph, maintained speed for a few seconds, and then punched the accelerator to see what high end acceleration was like. The car picked up (~95 mph), and then hesitated with rpms constant. I pulled over and let the salesman try to duplicate (which he couldn't). They took it to the shop and didn't find anything. The next day, I drove it again with the resident Audi expert. I was able to duplicate the problem while he was observing. He stated that the waste gate on the turbo charger was opening to prevent sending too much pressure to the engine. Problem never set a code and only occurred at the above speeds. Since normal driving conditions had no problems and I don't normally drive in the condition I was testing the vehicle, I purchased the vehicle (with extended warranty). The feeling I had during the event was that I was hitting a governor or something similar; not necessarily a mechanical mishap. Hope I didn't screw myself into believing what I wanted to believe.

extended warranty was good decesion
 

That sounds very similar to my issue but, it did leave a code... If your in the US I wouldn't think there is a governor I knew there was an issue cause I've been far past 100mph before this happened.

Another thing I see now that it is fixed was it was hesitant at take off a little and now its much more responsive when you hit the gas pedal from stop. You may want to at least ask the expert Audi dude if it could be the boost recirculation valve I was having trouble with.

Good luck,
Jason

^^ As Above or also could also be coils/wires on the way out.

it cannot be a wastegated issues.....especially since you are recreating the same amount of boost at wherever the needle is on the tachometer in 2nd gear that you are in 5th or 6th gear....so you should have the same issues going 40 mph in 2nd that u do going 100 in 6th.....its just physically impossible for turbo to create more boost at a higher speed because the rpm's are a constant....that resident audi expert just lied to you

This is a known issue on the A4 - and is a simple TSB fix. See the pic.

I spent most of the day yesterday trying to duplicate the problem under different conditions (lucky I didn't get a speeding ticket). Anyway, I was actually able get the problem to recur at lower speeds (lowest was about 60 mph). The common trait was heavy acceleration demand (pedal on the floor). RPMs ramped up like expected, but at some point, they just leveled out with no output. My vehicle speed began dropping even as I continued to have the pedal on the floor for several seconds.

I'm taking the car in this week with TSB in hand. This has been a great discussion, thanks for all the input.

if your dealing with high rpms and a loss in speed traveled, even when the pedal is pushed all the way down. if its the wastegate letting off too much your boost would drop down real low, but you would still be motoring a 2.0 liter engine so you shouldn;t be losing speed but just accerlating more slowly,

you could have a tranny issue if your RPM's continued to climb but your car didn't go any faster

Tranny wasn't slipping, so I don't think it's a transmission problem. Just 10 minutes ago I did post a code. Haven't had the code read yet, but after looking at other posts on this board, I'm betting it is the similar problem with the cam lobe that drives the high pressure fuel pump. I found the related TSB that I'm taking to the dealer (too large post, but here's the link http://www.goapreu.com/support/20t_cam_wear.pdf ). Just wish the dealer would have been as helpful as members on this board.

Do yourself a favor, call an Audi dealer, speak to a parts dept, ask them something along these lines.

I have a VIN, and I'm trying to narrow down a solution for a problem i'm facing. If I give you the VIN, can you tell me which part I have? (Intake cam etc etc) that's on your TSB.

I believe you're looking for the part that ends in B. - the older A ones were not properly heat treated, thus causing a lot of expensive problems....

You can also get any warranty work or services performed at any Audi dealer by giving them the VIN and asking for it.

vliou,

Good day, i was just curious... Where do you find these TSB sheets?

Also, curious to know... The Audi folks billed my warranty people for the high pressure pump and stuff... Should Audi have paid for these repairs even if it's outta warranty since it's a known Audi issue?

I have to admit I'm wondering if they should have replaced my cam lobe or other parts having to do with the HP Fuel Pump issue when it was there.

Thanks,
Jason

Hey man, definitely let us know what the issue is... I'm curious?

Jason

congrads on getting it covered!

The shop can't get me in until July 9, so I won't be able to provide any feedback for awhile. I did pull the DTC and it was P2293, which is the code that is mentioned in the TSB I posted.

Shop just called and said that the cam and cam follower were fine and that they are replacing the fuel pump control module (OEM part number: 4F0-906-093-K). They stated that the part failed a voltage test.

I haven't found much info on the net regarding this part, so I'm not sure what to think.

Anyone have any info on issues with the control module?

More info.... I asked if the cam, cam follower or pump had been inspected according to the TSB. Here was the response:
"No. The pump was not taken off and physically inspected. The pump passed the pressure and output quantity tests. Had there been wear it would have failed these tests. There was a very small number of vehicles affected by this problem. Of all the 2.0 liter engines we’ve had in here, I can only remember 2 with the wear problem."

Sometimes, mechanics are idiots - sometimes, I praise them till on end.

In regards to cam follower wear (on the intake), the mechanic is a complete idiot. First of all, based on the TSB, there are thousands affected. - if I remember correctly, you're looking for the part that ends in "B", not "A", and I believe only years 2002-2006 (or early 2007) were affected. My mid 2007 A4 had the new part already.

In reference to the other question as to where I get my TSB's, I bought the Bentley Publisher manual for the A4. Comes in a DVD, and I can search up all the TSB's.

I had mine replaced - the mechanic could not duplicate the issue, but since everyone at the dealer knows my name (SIGH), I had them escalate the issue to the district manager and he authorized that repair for me - as well as putting in headlight spaces due to vibrating headlights (due to the vibration of the TFSI engine). - also a TSB.

The $100 you spend for the Bentley Publisher's manual is the best money you can ever spend for yourself. It also provides me with light bedtime reading (I know, I need to get out).

Going back to the cutout, I have had one more "burp" in my engine even after the new part. The original TSB said that it is very sporadic, and it is due to electrical interference. - funnily enough, I realized it only "burps" when my garmin GPS is plugged in - maybe a coincidence, maybe not.

Stay CLEAR away from inverters, sometimes they are poorly designed and send signals back into your electrical system - and you know the Germans and their electrics...if you HAVE to get one, get one made by Xantrex - the power out of them are cleaner as well (True sine wave vs modified).

Hope this post helps some...

And usma - they are incorrect. If it has minor wear and has not punched a hole through it, your output test would have passed. On the TSB, you can see a picture with like 4 different levels of wear....

Just call up Parts, ask them a favor, give them your TSB and see what part you have on it. If it ends in B, you're good.

I was supposed to pick up the vehicle today. I received an email that stated, "The control module did not affect the problem. The technician has contacted our Audi Service Engineer for further assistance."

I couldn't resist being a smart*** and asked if they should re-read the TSB I sent to them. It floors me that there is a TSB with the exact same symptoms and DTC codes and they won't even inspect the suspect parts. This service dept. isn't inspiring confidence.

It happens - even my service dept. which I swear by did not see that TSB - it pays to be a diligent customer =)

At the end of the day, think about the mechanic who is forced to see X many cars a day...each of which have different TSB's.

My blame, if I chose to put any, would be on the automotive industry's shoulder's. Having TSB's and not making them recalls is....highway robbery.

Latest update......The control module did not fix the problem, so they replaced the fuel pressure sensor. That also did not fix the problem, so now they are replacing the high pressure fuel pump. All of this, without inspecting the cam lobe or cam follower. They are getting tired of me asking about the TSB; the last note I received, I was told that the techs are very knowledgeable, and are aware of the TSB, and if they think it will assist, they will follow the recommendations. With the high pressure fuel pump being replaced, I don't think they have any more excuses not to inspect the cam follower.

Picking my car up tomorrow (it's been ~ 2 weeks). They finally inspected the cam followers and replaced the followers, cam shaft and high pressure fuel pump. It's been a very frustrating experience with the service department.

Gotta love the know-it-all's at the dealers...
