My Audi Q5 2.0 Tdi from 2012 (pre-facelift) with 166,000 km shows me the error with low boost pressure in the turbocharger/compressor. The turbocharger is new, the wastegate is not. Could this be the reason?

It's possible that the wastegate could be causing the low boost pressure issue. Start by checking the wastegate actuator and its connections for any signs of damage or malfunction. Ensure that the actuator is moving freely and that there are no vacuum leaks in the lines connected to it. If everything seems fine, it might be worth having a professional inspect the wastegate itself. Let us know if you need further assistance or if you have any updates.

Hello thomastest, the hissing noise when accelerating could be due to a possible leak in the intake or exhaust system. A simple initial check you can do is to inspect the hoses and pipes for any visible signs of damage or leaks. If you can't find anything, it might be a good idea to have a professional mechanic take a look as this could potentially be a safety issue. Please let us know how it goes or if you have any other questions.
