Ok, so it had to go in for repairs and a re-test, but it passed!
Thought the rear brakes were beyond worn, nope, they went through fine. Expected to be told it needed some welding, nope! And watching the emissions test I didn't expect it to pass, but then I've never seen a diesel test before so didn't know what to expect!
Failed on excessive play on the track rod end on one side, and the lower swivel joint on the other side at the front. 1 advisory on a "slightly worn" driveshaft coupling.
Got it back today and had the "pleasure" of paying the bill, but nevermind, my car's roadworthy again!
