#668 of 1203 Oil warning by hellbent Feb 11, 2006 (10:44 am)
I replaced the oil w/ mobile1 5w-30 awhile back w/ a new filter, but ever since winter came around, the oil pressure light keeps beeping at me, could this be due to sludge buildup (im not sure what the owner before me did with the oil and stuff)...what should i do about this warning?

Replying to: hellbent (Feb 11, 2006 10:44 am) what kind of filter do you put in? Audis HATE off-brand oil filters. If it wasn't a German filter, you might switch a new filter in and see what happens.   Sludge is always a possibility. You need to dig into this problem ASAP and see what's what.

Replying to: hellbent (Feb 11, 2006 10:44 am) Mr. Shiftright is RIGHT about the oil filters. Stick with AUDI brand only.   The oil you should be using must adhere to stringent new oil standards for VW/Audi. Older model Audis were experiencing sludge and engine damage from extended drain intervals with inferior oils. That led to a new oil standard for Audi's.   For the A6, the NEW standard is called: VW 502.00. I don't think that 5W30 weight is the proper weight oil for this car. More importantly, you need special long endurance synthetic oils. The only approved Mobil 1 oil that I know of is their European formula 0W40 grade.   You can go to Audi's website and download a PDF file which lists the approved oils. Check out the new, custom made for Audi, ELF brand ("Motul", in Europe) "Excellium LDX" 5W40. It's specially made for extended drain intervals (though I personally recommend 5K oil changes regardless). This new oil is now (or soon will be) available at some Audi dealers. That's the correct grade for the A6, btw -- 5W40.(Certain other grades can be substituted, but they must be listed on the VW 502.00 approved oils list)   Also, don't forget that the newer A6 (3.2) takes almost 9 quarts of oil. Some auto service places don't know this, or about the VW 502.00 oil requirement! Replies to this message: Mr_Shiftright (Feb 15, 2006 9:26 am)

Replying to: legendman (Feb 15, 2006 1:58 am) Audis are extremely sensitive to oil filters and oils. I have actually seen with my own eyes a newer Audi TOWED to a friend's indy repair shop with the engine barely able to run....they switch out the oil filter,put in a proper weight of oil, and did nothing else whatsover, and the car ran perfectly. The hydraulic lifters could not operate with the off-brand filter. Amazing but true....

Replying to: goga82 (Feb 04, 2006 11:43 am) Hi, I am familiar with the problems you are having. I have a 2000 a6 that had display console issues as well (problem 2). i bought the a6 certified with a 100k wrranyt (I've got 48k on it now) so they replaced the entire console. Cost on invoice said ~$800 for the hardware. I've also looked for replacement head units to no avail. However, I did discover that Audi dealerships will install a 2005 radio if you don't mind the cost of the customization. As far as aftermarket head units go, let me know if you find anything! Good luck!
#674 of 1203 A6 Turn Signal Problem by bek Feb 18, 2006 (5:37 am)
The blinkers on my 99 A6 come on and stay on instead of blinking. All bulbs are fine. Flashers work fine. Indicators in dash come on and stay on too. Any ideas? Replies to this message: marleybarr (Feb 18, 2006 9:23 am)

Replying to: bek (Feb 18, 2006 5:37 am) You probably have a turn signal switch module failure. Had same problem on my A6, about $500.00 to repair through the dealer.

Replying to: halofan (Dec 21, 2005 5:41 pm) Did you get your new car?   After having a tremendous amount of difficulty with a new Dodge, the Chrysler Zone Representative was to confirm the new car pickup date. When several days passed with no news I called him. He claimed he had never heard of me and didn't know what I was taking about, in his very distinctive accent. I couldn't get him on the telephone again. My letters were ignored by all levels. I traded in the car as quickly as possible. Needless to say it will be a long time before I look at another Chrysler, like never. Replies to this message: halofan (Feb 25, 2006 4:25 pm)
