Vauxhall /peugeot P15A8 low oil pressure warning. wet belt fault. See description

This was a 69 plate with 36k on the clock regularly serviced at the main dealer from new. The fault shows as an oil pressure warning on the dash which started intermittently now is doing it all the time. As you can see on the scanner at timestamp 3.00 when reviving the engine the reading is in the 300s but should be in the 500s thus bringing on the warning light. On inspection the belt is badly cracked and needs replacing asap before the engine goes bang. Due to the high pressure at idle it may need a pump too as that may be damaged. The car also misfires badly when the fault occurs. Hope this helps someone out.
