Great, I went to a garage to fix a fault, vehicle had had two airflow meters new £400 and used £150 the mechanics there had a Strap-On scanner, they all had been on the Stap-On course.
I looked at the fault code, then asked for a large rag, was pointed to manky
Pair of overalls, wacked them up the wall, stuffed said overalls in airfilter with engine still running, carried on, bent down crack in intercooler size of small stone! They got a grunt, and was someone else’s problem.
Not always worth the effort!
