@Bertil,
Hey, have you had your G3 Kombi weighed?
Can you tell me, in this case, what 'enhanced' equipment you have on board?
If you scroll up a bit in this thread, you'll find the answer... (1430kg)
...
I think the combination

is about 80kg heavier than the limousine. The entire air conditioning system weighs approximately 30kg, the radio and navigation system weighs about 7kg, the 4 doors weigh 30kg, the sunroof weighs 10kg, the central locking system weighs 5kg, and the extra weight of the driver is 7kg.
...
The TÜV always says something when weighing...
I forgot the word 'where' above. (Tell me where...)
But you just wrote to the TÜV, right?
Here's the equipment list again:
You had:
Climate (automatic or simple?)
Radio-Navigation.
Sunroof.
ZV
What about:
Partition wall.
Wheels (wide/narrow, aluminum/steel).
Seat height adjustment (driver/passenger).
Roof railing.
Trunk cover.
Leather seats.
Rear headrests.
Side airbags.
Auxiliary heater.
Spare tire (wide/narrow)
Tow hitch.
With this information, I could determine the weight of my TDI more accurately.
