Hi guys and gals, I was wondering if anyone else has had this problem. I turned my car on this morning and noticed when I turned the lights on that the boost gauge didn't power up. It also failed to register any boost which I thought was strange any help would be appreciated thanks. Andy

My A500 is 3 years old and standard and have noticed an intermittant fault where the boost guage sometimes doesn't work (but the shift light does off SPORT). Sometimes it comes back on after I re-start the car but last week I checked all fuses and relays were in tight and made sure the connections on the turbo solinoid were sound - seems to have fixed it but I just don't know where the loose connection was - hope that helps.

After leaving it for a few hours whilst at work it now is working again. Thanks for the reply
