after a service my s3 has only one problem on the diagnostics= boost reads 990 mbr instead of an expected 950 mbr , what does this mean ?? secondly i fitted new stat n coolant cpl of wks ago all was fine untill i fitted the new plugs and gapped them to 7mm , ( old plugs were same brand gap was 9-10mm) today i noticed the temp gauge climb too 100 deg where as before it only went too 95 deg before the fan cut in .. advice greatly appreciated guys ???
