Tiptronic not engaging

[quattrofrank]

Hello

I recently bought an 97 3.7 quattro with 01V gearbox and tiptronic.
When shifting to tiptronic mode nothing happens.

I have checked with vagcom and when I shift to tiptronic the tcu register this, also when changing up and down.

No fault codes on the transmission except for load signal error message from ecu. This is because I have a problem with the maf (singal too high). Have ordered a new one.

Any toughts on why tiptronic isnt working? Could it be because of the maf error?
