Ok as some of you will know i've been having some weird things happening ever since I bought my S3 last November. The alarm has never armed and VAGCOM has never showed a fault with it. I have also had central locking stop working then start again and interior lights going on and off when they shouldn't. I had my central locking pump changed last month and this didn't cure any of the issues I had so 4Rings came back today to have another crack. I also had my rear arb changed and my wishbone bushes. The guys turned up at 10am and have only just left just as puzzled as they were last month. We do believe we have a breakthrough though!!! After some digging about in VAGCOM we noticed that the central locking pump thinks that my S3 has 4 doors and the rears being open!!!!!! This is stopping the alarm from arming and messing up my interior lights. The guys tried a few different varients of coding on my pump but they cant clear the 4 door issue! Has anyone got any idea be it stupid or not as to how I might be able to sort this issue out. It looks like one of the previous owners may have replaced the pump with a 4 door a3 or something.
