Keeps coming on approximately 300/400 miles after having been reset, the local garage that it goes to can't pinpoint the fault. Has anyone had this fault before or does anyone know what it could possibly be? If anymore info is required, please ask.
DISA flap,crank case breather and crank case breather pipe if you have codes similar to 171 172 192 lambda enrichment limit stop....these are by far the most common faults with 318.
