anyone know which version we are running? (ME?)

Check out Bentley's site. They have a few. Not too in depth tho.

$15 from Bentley, it's written by Bosch.

Check this out...
I started reading but havent finished. It's pretty good. But you should have some tecnological knowledge to understand some of it.
It can be kinda deep....<ul><li><a href="http://shop.barnesandnoble.com/textbooks/booksearch/isbninquiry.asp?userid=29TAK4HOK0&mscssid=2GEH7G0LTJC08KV979RMPQ3SAJRKD1W3&isbn=0262700263">Read this</a></li></ul>

...to learn. I used to read the shop manuals for my last car just because I was curious. Had a lot of interesting stuff in there, and explained (albeit briefly) how each particular system normally functioned. Had flow charts that described normal operation as well as trouble shooting flows...good stuff. I'm hoping that the Bentley CD will have some similar stuff - so the motronics seemed to be a good add on.

B&N sells the motronic book too, and I think they still have free shipping on two or more books. ;)

then yes. It even goes through the engine basics (combustion cycle, ignition, fuel, etc) but there are probably better books out there if you want to learn the basics about engines.

I presume its the same ECU on TT,

Just wanted to know what Pin 1 = ? Pin 2 = ?

because i want to add a piggy back compute in future.

thx for your help.

since Motronic ECUs are used in a variety of cars in different configurations. It's mainly a book on theory of operation.

If you're looking for a pinout, get ahold of a Bentley manual, it should be in the wiring diagrams (at least it is for my A4 manual from Bentley)
