Hi ppl i have a 88 mk2 gti 16v golf,and now and again the oil pressure buzzer will come on, the oil is fine and topped up,and its not the head gasket or anything like that,it seems to only happen after i drive it quite hard,it could just be a dodgy wire because when it comes on i just have to quickly turn sharpley and it will go off,but it only really comes on when i drive hard, any info would be great, cheers
