Hi all not been on here for a while as have sorted most stuff lately but hey this one has stumped me.
Got a Volvo C70 ENG code B5244s4 in at the moment with eml on,first job read codes,
130B mass air flow sensor break/make
6400 camshaft timing intake signal not in range
4000 EVAP signal not in range
1300Mass air flow break /make
6000 A?C compressor relay.
Looked at code and thought what a variation checked fuses found F35 in engine bay gone 15amp, thought happy days this is going to be easy.
But after driving out of workshop and 1/4 mile light back on. Same codes fuses gone tried turning off A/C still the same.
Another new fuse and faults cleared stayed of for a 5 mile run but then bang light on but this time a 250A code mixture adaption fault, checked o2 sensor scoped and showed slow response so fitted new, faults cleared ok. then roadtest light on and the original faults back and now started to blow fuse again. Help would be greatfull please.
