mk2 Posted February 1, 2025 Report Share Posted February 1, 2025 A few things... Ignition switch? Relay 109? Loose fuse? I think most probably electrical problem (if no lights on the instruments). My first thought was immobiliser. Do the head lights work? Check everything on top of the battery. Quote Link to comment Share on other sites More sharing options...
kurt7 Posted February 2, 2025 Author Report Share Posted February 2, 2025 Thanks for your reply iv been looking into the 109 relay as you suggested the symptoms are similar I'll replace that and report back but pretty certain it could be that Thanks again your a star Quote Link to comment Share on other sites More sharing options...
Rich Posted February 2, 2025 Report Share Posted February 2, 2025 It's relay 109 providing you're a TDI. If it's a petrol then back to the drawing board Quote Link to comment Share on other sites More sharing options...

mk2 Posted February 2, 2025 Report Share Posted February 2, 2025 If no mileage indication, then power is not getting through from the battery to the "off" circuit. Basically like the battery has been removed from the car (or disconnected). Yeah, I'd check carefully around the main fuse block on top of the battery. Those Ali fuses can develop hairline cracks. I'm guessing that the car was working just fine before you swapped the battery? Quote Link to comment Share on other sites More sharing options...
