I’ve an Audi A5 3.0 TDI Quattro 2008. Step 2 mapped with dpf off and egr, removed rear dampers replaced with straight pipes.
Yesterday when I started the car, put in my FM transmitter and the transmitter get broken. After that the car became completely powerless and the cruise control did not work. I’ve checked all fuses and they are ok.

What's wrong?

If you ignore the transmitter which was the only connection I made, where should I start troubleshooting?

What do you mean by powerless? No electrical power or no engine power, or low engines power?

Very low engine power.
Sounds like limp mode or something. Disconnect the battery for a while and then reconnect to let it reset. Make sure to leave a door open or something while doing this so you don't end up locked out.

You can also do a hard reboot by disconnecting the battery and touch the earth and positive cables together (not the battery terminals.) This drains any residual current and can help to reset your car.
