I am running the newer sensor (02') in my 97' A8. I had to trim the plug to fit into the socket, but they are the same. My old one had a wire all melt by the exhaust.

I just don't understand the Bentley's mix up....unless it's correct and my 98 somehow has an 00-01 sensor in it, lol.

At least now I know the plugs are interchangable between model years. Just hope it's not the ECU....:-)

Gentlemen, trying to find the location of the speed sensor G28 on my 1999 Audi A8. Found this thread with the reference to the picture, but no picture
Would somebody be so kind to post one?! Thanks for all the posts in this forum. I rebuilt the wrecked car, using your experience as a guide... I've been driving it for years now... It is time for a G28 sensor replacement!

My 2000 A8 would not start.
Turned over but sounded fuel starved.
VAG says:
1 Fault Found:
16706 - Engine Speed Sensor (G28): No Signal
P0322 - 35-00 - -
Pulled the sensor out from transmission. (See #7 in pic)

Cleaned it off with shop towel and MAF cleaner.
Put it back in. Car starts right up - no code.
The tip is magnetic and picks up stuff. Mine was dirty for sure.
If the ECU can't read that the engine is turning over, i.e. engine speed sensor, it won't put fuel at injectors and car sounds like bad fuel pump or spark plugs.
Seem like some may have unnecessarily replaced fuel pump/filter, spark plugs, or mistaken this for an immobilizer/key/cluster issue when all they needed to do was clean off a rubber and metal tipped sensor and screw its one hex bolt back into its hole in the bell housing area.
As always get VAG or have someone pull codes.
Don't replace this part until you try cleaning it first.
It really shouldn't wear out but it does get dirty.

Still running rough so I bit the $100 bullet and ordered and installed new G28 . Replace burned out fog light bulbs while down there.
Car is idling way smoother and getting slightly better MPG.
I take back what I said about cleaning vs replacing especially since MPG's was effected it's worth just replace G28 if you have intermitent G28 codes at $4/gal gas should pay for itself.
