Had a problem after eng managment came on. The Map sensore was surgestin a fault to which it wasn't faulty. Much testing produced slightley low compreshions on all cylinders (about .75 of a bar) After checking valve timming i concluded that the exhaust cam was 1 tooth out. Thus changing the -neg presure in inlet manifold which indicates a fault. s a note there was a sligh presure release in the induction manifold which sounded like a timming chain noise.

i didn't take the head off but stripped the timming gear down relpacing the bottom sproket, chain, and tenshoner. Before starting the car after work i purged the oil system after changing oil and filter, and took off fault codes.

The engine started and ran well, no issues or concerns!!! a VW mate set the service light since then the engine managment light has flased on once !!

Anybody got any ideias as to what is going on, theeng runs well with no issues!! ta Fishtoft 01
