I have a Passat '06 103 TDI Wagon and have been wondering if I sould be concerned about it.

Does anyone know if VW produced them at any tim without TDI badges on the back tailgate as mine only has PASSAT on the left hand side without TDI written on the right. should I be concerned?

Should I be bothered getting one?

I have an ongoing joke with my wife that we are a 'reverse sleeper' they will thrash me at the lights but I'll be getting 6-7L / 100. Hilarious.
