My friend is gonna dyno his car on a 2wd dyno.
Is there a fuse I can pull to disengage the awd?
Or do I have to disconnect his driveshaft?
Is this even possible to do?

Thanks in advance guys.

 

i'm guessing that it has a 4motion AWD system since it's so similar to a Phaeton. if it's a gen-V Quattro, it can put 100% power to the rear, so i'd imagine it'd be as simple as pulling a fuse. but from what i've seen with a few quick searches and some scanning is that with 4motion, there's a lot more involved. (insert disclaimer here, i've never worked on a VW/Audi/Bentley type car before.) so what i've seen is that you have to remove the transfer case, put in a 2wd flange, and use an adapter plate to close it all up.

is he using a 2wd dyno by choice?

 

We don't have a 4wd dyno locally so we have to use a 2wd dyno.
I still don't know how we're gonna pull this off.
I know on my 996TT I just have to disconnect the driveshaft.

 

unfortunately, there are some big differences in AWD setups. take your as an example: with a 996TT you can just pull the driveshaft, but with a 997TT it isn't that simple. on my STi you have to open up the transmission and either weld the diff or put in an adapter. from what i saw while looking for an answer, VW's 4motion requires as much effort as Subaru's to convert to 2WD.
