I am almost in the game using the excellant work of Robby BMW who created this thread.
Along with the work of the two forum members

who have added greatly to the project. First _Dejan_ and juve021 offer boards, also juve021 who contacted the vendor of the 3rd Eye TPMS system and procurred a 10% discount. It's not that much but it is something.
Just an observation carcomputing is not necessarily cheap, but it is useful to remember "that whoever dies with the most toys wins".
Progress todate:
Using juve021's 10% I have ordered the TPMS form vivaperformance $237. and change.
From _Dejan_ (on the other side of the world, I am in Maryland) I ordered the board with PIC with shipping 79.00 USD (53.00 EU). And shout out to _Dejan_ for rushing from work to Post Office to get this out today. We used PayPal.
See these links and contact them for support.

Ordered from vivaperformance Wednesday night, should arrive Monday.
My car shop, Jr's in Laurel, MD has quoted me 15.00 USD / wheel which would consist of unmount wheel, remove tires, install sensors, reinstall tires on rims, check for leaks, balance and remount on car.
So another 60.00 USD. So total will be 237 + 79 + 60 = 376.
I am handy with the electronics, so finishing it on this end should be a breeze, probably not likely to get this completed before new year as my car guy is closing up for the holidays on the last week of the year.
Is it worth it, depends my 1997 VW Passat, original owner, totally revamped, all new electronics, is riding on Toyo Proxes4 and DeCorses rims, keeping them properly inflated will extend their useful life. Also keeps the gas mileage up, properly inflated tires really do contribute to fuel efficiency.

For me though this has been an ultra cool project and the TPMS just adds to it.
Next step, tie in ODBC USING VAG-COM, also USB-UIRT to control the headunit.
