I recently lost my dash cluster directions/display (TMC). It could have happened in one of two ways:

1) removal/insertion of unit sliced a critical cable
2) jumpstarting my car fried the TMC

I have confirmed that TMC is getting 12V.
I have confirmed that can h/l wires from TMC to 26 pin are solid
Need to confirm can h/l wires are solid to cluster still.

Anyone know how to check a TMC to make sure its not dead?

VAG tells me the below, anyone have any ideas? I need to get this sorted so I can button the darn car up and just enjoy it for awhile...

Module 19 - CAN Gateway is not responding

Hi All,
COnfirmed that all of my in and out TMC wires seem correct and are not broken. CAN H/L to cluster signals as solid and CAN H/L Info to 26-pin connector signal as intact. Ground is ground and +12v is +12v. Confirmed that it actually gets 12V when ignition is lit.

So, it feels like my TMC is bad, maybe I shorted it at some point.

One thing I did notice is that VAG tells me module 19 - CAN Gateway is not responding. If the TMC was good would it respond here?

Trying to find out how to determine a dead TMC before I enter the Ebay Sweepstakes and/or spring for one from nav-plus.

Thanks all
J

Shouldn't your nav+ unit give a message if the TMC goes down? Same as if it weren't fitted?

All fixed

You get an ambiguous 'trouble communicating with cluster' error on both the Nav side and the instruments side.

I bought a new TMC this week, plugged it in and its working great.

Wierd that something like a TMC can suddenly just die. Glad I am back in business now, one less issue on this old car.

This may be a daft reply and I may not have understood your problem correctly but -
I had a similar problem where my DIS just stopped working, then I relasised I accidentally turned it off with the bottom button on the wiper stick. Sometimes we don't see the wood for the trees!

My TMC was bad. I would get all my normal DIS stuff but the directions and Audi-Nav would not come up (for example I ran out of wiper fluid and that error message came up fine).

I just swapped the new TMC in and everything was back to normal. Quite nice.
