I am going to give my 2000 A6 2.7t a tune up plus passenger side oxygen sensors and transmission fluid (manual). This is my first German car so buying parts for it is different than a American car. So I have some questions.
1. I hear that I should only put Bosch sensors in, where is the cheapest place to buy them?
2. what kind of spark plugs should I use (by brand and type)?
3. how much oil does the tranny hold? its a 6 speed manual, and I should use Mobil 1 synthetic 75w-90 gear oil, right?
4. it needs a new abs module, how do I know what part number to buy? other than taking off the old one to look?
Lastly the coolant is a little low, I know i have to use G12 but there 3 different kinds of G12, normal, plus and plus plus. what one do I use?

Thanks in advance

 

You can use universal 02 sensors but they require a little modification in the wires.

I believe the tranny holds 9 quarts but this is for the automatic. And use any oil that's approved by Audi / ZF for tranny fluid

Spark plugs use oem NGK. Don't recall the part number but it's recommended on NGKs website.

I just it my g12 at Volkswagen dealer for 25 dollars a gallon

 

anyone else have any input?

 

Im going to buy oe NGK laser platinum plugs, which are $13 a pop. I read some where that the manual transmission takes 4 quarts, can anyone verify that? Im just going to buy standard G12 coolant. The things still I need clearing up on is the oxygen sensors and abs. Plus today I noticed brake fluid is leaking from the driver front wheel and the front passenger cv boot is torn in half, so im going to replace the whole axle.

 

I suggest you stick with Bosch O2 sensors. Try your dealer or ecstuning. They only last about 100k miles per my indie, but replacing them AND the cats did not solve my cat CEL.

Before you go for a new ABS module (about $1200 from dealer), pull it out and send it to modulemasters. They can rebuild for < $300 (I have not priced it lately) and you can drive the car w/o the ABS.
