Question 1

Which Audi Q5 diesel is the better buy, the 2.0 or the 3.0 TDI?

Accepted Answer

The 2.0 TDI four-cylinder is cheaper to run and to tax, and enough for most drivers. The 3.0 TDI V6 is smoother and pulls harder when towing, but costs more to maintain and pays more road tax for its higher CO₂.

Question 2

How much road tax does a used Audi Q5 diesel pay in Luxembourg?

Accepted Answer

The CO₂ figure × 0.9 × a band factor that starts at 0.5 up to 90 g/km and rises 0.1 every 10 g, so half as much again as a petrol Q5 with the same CO₂. Cars first registered before 2021 use their NEDC figure, later ones WLTP.

Question 3

What should I check on a used Audi Q5 TDI?

Accepted Answer

The particulate filter, which short trips clog, and on later Euro 6 cars the AdBlue system, whose faults can stop the engine restarting. Ask too whether any emissions recall work was done on the car.

Question 4

Can I buy a used Audi Q5 diesel in Luxembourg if I live in France or Belgium?

Accepted Answer

Yes, but you register it at home, as the SNCA registers cars only for residents listed in the national register. A dealer's car carries Luxembourg VAT, or none shown under the margin scheme, and no VAT is added at home on a used car.
