Audi Q7 P0700 error - bokinis - 31-03-2025
Hello everyone. I have a problem that I have not encountered before. It is an Audi Q7 model, 3.0 tdi engine. Before it was parked, the heater light came on and off several times. The engine now does not start anymore. The fault is P0700. I found on a couple of forums that it was about water, software. Opened Ecu, it's dry. I found the original software, wrote it down. The engine still won't start. If anyone has had such a problem, I would appreciate some advice. He apologized in slightly weaker English.

that fault code is about tcm failure. Do you check the tcm units ?
