Has anyone ever used BG 44K fule additive or BG MOA oil additive? If so, are they any good? I have heard good things but I am leary about using them on my 05 4.2.

Save your money, just maintain your car exactly as Audi recommends.

I agree & wouldn't put any additives in. The older your car gets, you might want to do sythentic oil every 5k instead of the regular 10k service intervals.

Even that will be excessive. I pulled the heads off of one of our cars last summer, a car with nearly 145,000 miles on it and had only had its Mobil 1 changed every ten to twelve thousand miles since it was new. So? Well, believe it or not, the cylinder walls still had the factory honing marks easily visible to the naked eye on all six cylinders. Given that I've torn down many-many engines and never seen an engine lubricated with conventional oil go even 75,000 miles with such a small amount of wear, I was really impressed.

Going back 30 years, I changed the oil in my 240Z every 3K miles (more or less) & at 200K miles decided to tear the engine down because it smoked on startup. Didn't use a lot of oil, but the consumption had gone up.
 
Well, all I needed was stem seals (if you don't know what they are, it's a relatively simple fix that can be done from the top without tearing the engine down) & I was pleased (& impressed) to see the hone marks in the cylinders after eight times around the world. I still respect Nissan & straight sixes (not in that order) after that.
 
Bear in mind that oils in the '70's weren't anything near as good as they are now.
 
Change the oil on a regular schedule & use the best money can buy. Repeat.

The motor in the original 240Z was one of the great motors of that era.

try to replace the fuse(s) for the dash lights, etc. Should be very inexpensive ($10!) Not sure if Audi has them all labeled in the owners manual. Don't let the dealer charge you for a new dash if you haven't had someone look at that first. Same was happening on my Saab (when it was 6yo). Otherwise it could be a defective dash illumination switch.

Good ridence Audi by lenbroverman

I finally solved my problem with my 2005 A6. I traded it for a new 2008 Cadillac CTS. Not that I didn't think my A6 wasn't a nice riding car(I had a 1998 A6 before it) but I was tired of Audi's customer service about a problem with my car. My car had an annoying clicking noise that I would hear in the car when the climate control called for heat to the cabin. After having many service techs try to find and fix it with no success I finally wrote to the president of Audi to seek help. I was contacted by his representative who arranged for a field representative to come a listen to the clicking. He diagnosed it as a noise that comes from the heater vent doors that open and close as they distribute heat to the cabin. He said that it could not be corrected and it was a "characteristic" of the car. For most Audi drivers they probably wont hear the noise because for some unexplainable reason it would only happen when the engine was reeving at about 2800 rpms or higher. If you drive in automatic your engine probably shifts to a higher gear before the engine gets to 2800 rpms.,but since I use the manual shift mode(that's why it's there) I typically would run the engine higher than 2800 rpms before I would shift. So since Audi had no solution to this "characteristic" of the car I solved the problem by trading it. By the way my car only had 26,000 miles so it was still relatively new. As I told Audi I wont buy another car from them and I hope the president of Audi car doesn't make the same noise. I love my new Cadillac CTS. Check it out.

Based on my experience -- which is over 2 dozen Audis deep -- I would say you took a step sideways. I have the 2005 A6 3.2 Q with all options save sport suspension. Your CTS MAY not have the "issues" your A6 had. You did not, however move forward -- indeed, based on the fact that the 2008 CTS with every possible option almost measures up to the 2005 in terms of features and amenities, and due to lease costs, costs more per month. . . .er, I would say you actually moved back a step.
 
Your reliability issues are not typical. Your opinion is, therefore, NOT representative of anything other than you singular experience. And, by the same token, even though I have had several dozen Audis without the kind of issues you describe, neither is my opinion representative of anything other than my plural experiences.
 
I really like the new CTS -- a lot. It is about equal to a 2004 Audi A6 2.7T SLine overall, however.
 
My primary attraction to the CTS WAS and I assume will be, the inevitability of huge off MSRP discounts to compensate for its rapid depreciation and "not quite" German car feel. Secondarily, I want(ed) an American car, I wanted a car that was really as good looking as the new CTS is and I assumed the CTS would be a drop dead bargain (after the first 6 - 9 months on the market.) I had hoped it would be the equivalent of a 2005 A6 3.2 quattro with Premium, Premium Leather, Technology, Convenience, voice command, MMI, back up sensors, etc etc etc, plus sized wheels and tires and all the rest of the German toys money can buy.
 
Alas it just ain't so.
 
But if it comes in on a lease with a number beginning with a "low 5" -- I'll overlook its being "state of the art," circa 36 months AGO.
