#1307 of 1407 Catalytic converter Failer
Aug 25, 2010 (5:34 pm)
willie94 My right catalytic converter now failed in my audi A6 2003 AVK 3.0 After I had 6 ignition coil replaced Thur recall due to 1 ignition coil went bad. Also cam position sensor went out well as my mass air flow exchange the change over barrel broken between Actuator mechanism and timing belt change. In all 3,155.07. I had letter from Audi Oct 09 said not to bring the car in unless the check engine light came on <(MIL-Malfunction Indicator Lamp will illuminate then let us know)=from Audi letter.. This check engine light came on in August 2010, one coil failed, and also my car was shaking so badly too. That's when I got this fixed and now right Catalytic converters has fail.

Are you the original owner of this vehicle???
If it's a diesel engine and depending on the model (Vehicle year) the catalytic converters in earlier models were not self cleaning;ie, they got dirty after a number of years then have to be replaced. This has since been changed, in that, catalytic converters are now self cleaning. OK.
If it's a Gasoline engine, then what kind of motor oil are you using?
See an earlier post of mine with a link to a PDF showing all approved motor oils for Audi/VW.
I don't mean the brand, I mean, Mineral based or Synthetic? VW/Audi has recommended Motor Oil standards and they should be followed. In particular Mineral based motor oils leave deposits on the "Lumda Sonda" sensor which is usually located in the catalytic converter. Check your owners manual or the Audi Web page for recommendations. Another options would be "The Car Bible" web page http://www.carbibles.com/engineoil_bible.html#blackdeath.
I don't know what kind of Cam Positioning Device your Audi has but in my previous BMW it was an electronic devise with no moving parts. If it went bad it would seem to me that your engine would have been trashed as all the timing factors related to Valve and piston timing would be non functional.
As for the Air Flow meter meter, I've read information, again on the Car Bible, that spraying cleaner fluids, to remove dust, for exampled will level deposits on the hair fine wire causing it to give incorrect readings. Of course the control device for that unit is electronic as well.
I'm not familiar with the abreviation "AVK" but if it' means a rebuild engine, who did the work????

AVK is Engine Code
CAT Converter has mandatory waranty of 8 years / 80,000 mi ... Audi has to replace it for free if within that.
For reference : Mini-Cat-Cel-Fix
There is MAF sensor cleaner made by CRC ... I saw my local PepBoy carries it.

I drove the car and parked it as always. Two days later the lever will shift from P to R and to N, but it won't shift to D. I really do not know what to do anymore.... Any help?
#1311 of 1407 Engine Light On- Audi A-6 - 2006
Nov 15, 2010 (3:14 pm)
My engine light has been on since March of this year! My dealer said it would need to be analyzed for $360. Received the Ignition Coil letter; checked with the Audi website today. It responded that my Vin # was not one of those with the problem. I've just added about 1 quart of oil in the past 1.5 months. I'm thinking it's the engine?
I now have 98000+ miles on it and need my 95000 service done. Any hints as to what I should be aware. I know those service fees are exhorbitant and would like to lessen the "bite." Thank you, skiddadle

The check engine light came on in my A6 as well. Took it to the shop for the diagnostic ($89) and they informed me that the left catalytic converter had gone bad.

1.Engine light on which model A6;ie, Quattro 3.2l, 4.2l, 3.0l Turbo.............
The engine type would determine if you have one or two Catalytic Converters.
2. If your engine is using more than 1 quart/1000miles and I assume it is because your adding Oil.
My Question is what kind of oil have you been using for the last four years or since you've owned the vehicle?
3. The "Engine Warning light" will come on for a number of different reasons.
If you've been using a low grade gasoline, fuel or oil additives which are not recommended they can contaminate your Lamda Sonda sensor which is mounted directly in or near the catalytic converter/rs.
If will answer these three questions then I can be more specific.

OK, it's a multilevel problem in that it could be any one of several general areas pertaining to the Transmission and supporting elements:
1. Does the Lock release button on your Gear shift lever work?
2. What type transmission due you have:ie, Automatic which type?
3. Is the battery in the vehicle OLD or new?
4. Does your vehicle have All wheel drive (AWD) quattro with Electronic Locking of
the wheels when the transmission is in Park.
5. Do you hear any clicking sounds from the following areas when starting the engine and moving the gear shift lever to P,N,R?
a. Clicking near the Ignition switch
b. Clicking near the Gear Shift lever.
c. Clicking when you step on the brake, engine running or not?
If you can answer some or all of these question perhaps we can narrow it down do just a couple areas.
Note: If you don't feel comfortable with all this then have the vehicle towed to a reliable Audi Dealer or Certified Independent shop who has knowledge of Audi and the necessary test/Diagnostic equipment.
Your next question should be "What is a reasonable answer to your problem".
I would say that if the transmission gave you no problems/unusual noises or low fluids (ATF), then it could be a simple as a broken control switch, or low ATF Fluid, a control valve within the transmission, loose mechanical connection of the gear shift, a ECU (Control Unit) which control the Transmission functions or a combination there of any of the above. Without more information it's difficult to narrow it down.
An authorized Audi service center would be your best beat, but don't let them sell you a new/rebuilt transmission at this point.

Interesting turn of events. After taking the car for a diagnostic due to the check engine light coming on...the light has now gone off by itself.
#1316 of 1407 Damage to a lease
Jan 04, 2011 (12:41 pm)
Hi & Happy New Year,
I have sustained some damage to my front passenger side along with some slight damage to the grill "bezel". My local dealer quoted me around $2200 for repair. My question is two-fold,
1: Should I just wait until I turn the the car in (5 months) and just deal with what they say then or could that backfire on me?
2:If I take it to a local collision shop and obviously save some cash is it possible when I do turn it in that it won't pass their muster and I still get hit for more fees?
