The motor lamp started to shine bright a couple of days ago on my old trusty SAAB.
Got a cheap ODB reader, and saw the error codes and Joakim Melin (npub18uw…gly7) sent me a video that explains how to solve it.
It turns out that the part costs a dollar (a small metal clip) that keep the dump valve in the correct position and it took 3 minutes to fix.
