Attention C6 Owners experiencing oil leaks from timing chain cover gasket!
 

I currently have a case in with AOA regarding an oil leak concern. It has been an issue for me for the last 80k miles in which I have been noticing oil residual all over the bottom of the undercarriage and bottom engine cover. On multiple visits I addressed this concern to the dealers and for the most part I was told that what I was seeing was just residual (bunch of BS) however the actual cause was just detected. All the oil has been coming from the rear timing chain cover gaskets and all this time I was always told from the dealers that there was no leaks found. Big problem is that most of us are outside of out warranty and stuck with a rather large repair of around $3 - $4k (primarily labor time of dropping engine and tranny). There is a good chance our 3.2L engines may have a design flaw. At this point Im still waiting to hear back from AOA on how they want to procede with my case. In the meantime any of you who have the 3.2L engine who have or are currently experiencing this same issue, please give your feedback and note your concern. Audi may have been hiding a huge repair that should have been recalled. And its my best guess that since this leaking of oil is not necessarily a "safety" concern they never went forward with a recall because it would involve a lot of repairs and a lot of money out of their pocket.

Hit me up guys.

Thanks

Thanks for the alert. My '06 A6 Avant w/ 57K miles on it doesn't any oil leaks yet, but I will certainly keep an eye for any oil issues and advise.

May also be a good idea to always request to physically go into the shop and talk with the techs to see with your own eyes. I don't trust these guys 100% and of course theres always room for human error so if you do see a leak and its not detected, I would be as persistent as possible and not leave the shop until they verify where its coming from.

The oil leak on the 3.2 is a known problem and Audi has issued a TSB. I believe the old leak TSB is included in my TSB library.

oil leaking from covers at the back of head and valve covers (that was on my invoice). I was at 40k, now on 50k miles.

Here it is but it does not mention the 3.2 http://uberlame.com/a6_tsb/Engine/Oi...ne%20Areas.pdf-

Since I am the person who created the TSB library I am familiar with it.

3.2 not listed in your TSB Library .....
 

Since you are familiar with this library, as you created it , PLEASE show us where it lists the 3.2, instead of the wiseness..
