Should be 2.5 bar with vacuum on the FPR or 3 bar with no vacuum. Quote Share this post Link to post Share on other sites

*Glenn* 854 Report post Posted April 2, 2008 I'd find another mechanic and get it checked properly first. You could end up on a wild goose chase. I think its Page European down in Welly that does good work.. others could help you out with a good repairer in Welly. Cheers Glenn Quote Share this post Link to post Share on other sites
