Tire Pressures eversed on DIC?

Hey guys...
So, I've come to my first issue w/ my 08 A6.
I installed the HUD kit yesterday (2LT, non-HUD car), and now it seems my front tire pressures are reversed on the DIC. The rears are fine. ...and the HUD works great w/ the non-HUD windshield.
It's also taking the sensors up to a few minutes to update new pressures

I thought I may have simply wired the gauge cluster backwards somehow, but that's not possible as the connectors to the three wiring harnesses to the back of the cluster are keyed differently. So there's only one way to make the connections, w/ 0% chance of crossing them.

I started late in the day, so I didn't have time to finish at once, so the car sat overnight w/ the battery unhooked.

Would this be a case of simply needing to have the dealer reset the DIC? Should I consider new sensors?

Anybody got a wiring diagram I can study?

Thanks for any help or info.

*Sorry - title should say"Reversed". LOL!

get a TPS scan tool and scan the TPS again in the proper order and see if that resolves your situation first.

Correct. Someone must have switched the wheels. Reprograming the sensors will fix it.

I did the HUD and if yours is working speed,rpm etc.. cant see how you got something miss wired.
you can get a tire rest tool off tirerack.com for a hundred bucks and reset them if your self (easy to do, if you were closer you could stop by and we could get it done) . good luck with it, paul

Discount Tire did mine for no charge. Only takes 2 or 3 minutes.

Yeah, the front tires had been changed before I got the car. My fronts have z-rated Nexen's and the rears are Goodyear F1's. But I can't just swap wheels since the tires are directional.

I hadn't paid much attention to the pressures since the tires are in great shape and hadn't had a need to put any air in them 'til it started getting colder.

I'll just take it to the dealership when I get back home to TN and have them do a reset.

Thanks guys!
