@all and a happy new year! 
I need some help for Golf5 Plus 2.0 8V TDi.
Engine Code BMM, year 06.2008, 124378KM.
Error Code is: P0546 Exhaust gas temperature probe 1 Bank 1, Circuit faulty/Signal too high.
Sonde is new! Error Code delete and you can drive, and the lamp stay off!
But in the morning (12 Hours later) if you strart car the lamp going on!
If i look on the parameters, i can see the Temp (Ca. 128°) and Volt (0,5V)
I don't understand this!
How can solve this? Please help and thanks.
