Sarah gallagher Posted November 11, 2017 Share Posted November 11, 2017 I have a o3 ford focus 16 zetec.. but ever since owning it I've have issues.. the Speedo does its own thing when it feels like it and for some reason is connected to the stereo.. when the Speedo jumps the volume gets loud... Isn't very good pulling off.. doesn't like hills unless your in low gear.. the engine light is constantly on... ATM the Speedo doesn't work at all... Has no real power to it... The milage display is just blank... And this week is drinking fuel... Just done a self diagnostic test and the code flashing is D123 ... I feel I've been sold a dud and have been saying forever there is something wrong with it but no mechanic I've been to knows where to start...

Micro Posted November 12, 2017 Share Posted November 12, 2017 The radio getting loud when the speedo goes mad is because of auto-volume levelling. Quote Link to comment Share on other sites More sharing options...
