Volvo S80 2.4T Pierburg TCV 7.22908.03.0

Replaced the Aliexpress Pierburg valve with a brand new original Pierburg unit. These are also known as the “Porsche” TCV and sold by ARDideas. Must have part for about 20-30 euro.

The difference is noticeable, especially when driving with half throttle.

Volvo S80 2.4T Fitting a new Compressor Bypass Valve (CBV)

I noticed some strange behaviour when lifting the throttle and decided to service the CBV aka Compressor Bypass Valve. I was right, car drives a lot better after replacing it with a fresh CBV / DV (Diverter Valve).

I went with an aftermarket TRITDT K5T09671.
