Hi reset the ecu , i have fitted g/box temp sensor in oil pan , before that i tapped into ecu g/box temp wire and connected it to guage that didnt work so fitted separate sender. Have carried out some work down by ecu , so maybe issue is there, have checked for fault codes, none in memory.

Id say electrical too given it only happened after work done, reverse everything as said above.

 

Also wondering why you tapped a sensor port in as the ECU gets a reading from an OEM temperature sensor? Can be read with an OBD reader like the Blitz iVit....

Fitted seperate guage for gearbox temp, thought i could use signal from gearbox temp sender.

How & what was wrong?

 

I fitted a push button start switch , wired into the starter trigger wire off the ignition , for some reason this wire has a connection to the tiptronic ! Without a wireing diagram, cant explain this , and will now have a think about how to wire the start button.
