Replace the little piece of hose inside the ECU, and the hose from the upper intercooler pipe to the ECU. Clear the code.

I recommed silicone tubing. 1/8th inch or 3mm ID works great.

Awesome !!! thank you very much for the fast reply& help on this.

Hi,
My 2.5 TDI A6 C4 AAT ECU sometimes shows the same fault code.
This ECU don't have any tubing from intercooler.
Any ideas?

Sorry, no. We don't get that engine here.

K line wire wasn't in the place, bad contact. Now all OK.
