Tiptronic 2.0t TCM Location? Depress clutch pedal to start engine?

[iamshayan]

Have a puzzling question hopefully someone can help out with.

Put a new engine in my car - same trans - same ecu - just swapped the engine.

Went to start it and it says - Press clutch pedal to start engine. ITS TIPTRONIC THERE IS NO CLUTCH PEDAL!



Scan with vcds shows -

1 Fault Found:
049409 - No Communication with Transmission Control Module

When I try to access " auto trans " in VCDS it says no response from controller.

So I'm trying to find the Trans Control Module. I havent found a conclusive answer yet on where it is located.
I understand that for CVT transmissions its located in the transmission itself. (i am not CVT)
In a b5/6 its located under the ecu.
Does the B7 ME9 ECU have the TCM integrated?

anyone have any idea on why this would happen?
Thanks.

Bro, i didn't know you got a b7. Congrats!

Did you remember to plug in the trans?

[iamshayan]

Yeah I sure did, I even tested continuity and voltage on the plug suspecting that it wasn't getting power.

Connector looks kind of like this- but not really



results were :

• 1- 1.77v
• 2- 2.38v
• 3- 11.5v
• 4- 5.43v
• 5- 5.43v
• 6- 2.63v
• 7- unused
• 8- unused
• 9- 3.06v
• 10- used but no voltage no continuity
• 11- 3.30v
• 12- unused
• 13- ground
• 14- 11.9v
• 15- unused
• 16- ground

battery voltage = 11.96

of course these results are useless without further information.
can't seem to find a pinout and haven't got my hands on a bentley manual yet.
if anyone could help it would be much appreciated.

I am now assuming the TCM is built into the ecu if the main harness has that many pins on the connector for the transmission.


also some random info fwiw

- i can shift without pressing the brake pedal down when the ign is on.
- when i press the brake pedal the little foot symbol thing next to the P stays illuminated
- the brake light switch does work and my brake lights do come on when pressed.

I HAVE THE SAME EXACT PROBLEM!! just rebuilt my head after melted valve, spark plug electrodes breaking off & wreaking havoc internally & broken cam tensioner guides.
Replaced every internal component, reassembled, invited all my friends and loved ones for the grand finale.. turn the key.. full power, but no crank.
Total humiliation. Irreversible Emotional damage.
Anyway, have All the same exact symptoms as OP says. Lost communication with Tcm. Though I didn’t touch any wires or anything with the transmission. Anyone have a solution ??

@06AudiA4Quattro - Seems like posts 4 & 5 described a possible solution; have you tried pulling that fuse?
