Audi TT diesel

Hello people, sometimes enough with the fuel prices yes I know the statement who drives a TT should also be able to afford the fuel. I can also afford it but I see it if I’m honest not a it’s just about the principle. The question there is a company remodeling a TT? Or maybe someone already drives with diesel in your baby. Unfortunately I drive many km about 40,000 km year but also net wants to separate from the car and also doesn’t like a 2nd car. I’m now since no For almost 4 years now, I’ve been falling for the TT and I want to keep it that way. Of course, my engine will be left with a 150hp 1.8T with 50,000 km and a Wimmer chip. Would look forward to contructive answers. Greeting Christian
