@etmanning1 how much do you miss Wawa already now that you’re in Phoenix? I’ve worked there for 10 years, and I’m only 27


Haha, I used to get the Wawa buffalo chicken wraps on my way home from the gym all the time. Quicktrip just doesn't hit the same, that's for sure.

My new axle arrived and I threw it in the car yesterday afternoon.

It was extremely nerve-wracking finally taking the car off the stands, but thankfully everything seemed to be working properly on my short initial test drive!!

Steering response feels immediately different due to the differential, and I can't wait to get the alignment dialed in so I can start to push the new setup. I'll post some driving shots/updates later in the week hopefully.

You can also see the diff module "mounting" in the above photo. For now, I have it just zip-tied to the subframe, and thankfully there are no codes lighting up on the dash!

You do realise that the subfame already has the three nut threads for either the VAG skid tray or the thin full aero tray.....which would stop alot of dirt getting up in there...

Just be careful ordering one with front ducts..or the thin GTE one which has loads of ducts..if worried about heat build up...

Well, things can't ever go smoothly, eh?

As you can see above, there seems to be an issue with the new trans. At this point I have about 50 miles on the new setup, and it drives incredibly!

The outer seal between the transmission casing and the right hand axle cup ripped clean in half, and is now puking transmission fluid all over the nice new subframe and everything else under the car.

I replaced the seal on Monday with factory part #02Q-409-189-A . All seemed good on the initial test drive, but this seal too appears to have begun leaking.

Is there a different part number for the outer seal on a non-pp transmission? I can't imagine that VW would use a different size, but what do I know?

The leak was small enough with the replacement seal that I was able to limp the car to alignment, and it should be finished up this afternoon.

I'm finally getting close to having this thing sorted, just have to fix this seal and tie up a few loose ends!

ETKA parts...I know its just a 2016 year hatch diagram..but the VAQ unit is for the PNP code manual MQ350 gearbox...looking at these..there is soem differences

Item 3... here there are different ones depending on with or without VAQ unit (you need 02M-301-189-G for non VAQ)

Appreciate it! I'll try and source that part # and give it a shot. Of course I used brand new axle bolts last time, getting tired of buying new ones haha.

Indeed. I have hopes of one day doing an ABS or similar underbody tray to work with full front/rear aero. Still lots of time left in the car before that, though. I'll look into these for now.

Quick update-

Part # 02M-301-189-G did the trick to seal the transmission! The inner diameter of the opening is maybe 1mm larger, which is just enough to fit around the axle properly.

I flushed the transmission again after verifying that the seal was solid, and now have about 300 miles on the car since the build. I'm still tweaking damper settings, and moved the front sway bar to the softer position.


The car feels great with the new setup, and actually seems to run more smoothly than before. The transmission whine is gone, and for whatever reason clutch chatter was also reduced. Initial impressions in the canyon are that the car has WAY more grip, especially the front end. There were quite a few corners which I usually downshift to second that I was able to easily take in third with the suspension changes! The transmission shifts very smoothly, and the steel forks/feet combo make quick shifts during pulls lightning fast.


Not everything is perfect yet, but I'm working to dial it in every day. More OBD11 coding is on the to-do list, as well as another alignment appointment to make a few adjustments after having driven the car. The non-PP axle is thicker than before, so it had been rattling against the sway bar occasionally over bumps. I'll need to adjust my endlinks soon to avoid this. Hoping to hit the track soon!
