MattR 0 Report post Posted November 7, 2017 Hi All, Dont appear to be having much luck at the moment with the GT86 - currently in the middle of having an aircon issue diagnosed and now getting a high pitched whistle noise. I have looked it up and I’m aware of the chirping noise borne from an issue with the fuel pump, however this is less of a chirp and much more constant and high pitch - no other video I’ve found has sounded quite as bad. It’s definitely high pressure. Share this post Link to post Share on other sites
