Hi guys I'm new to this so hope I'm posting in the right place. My engine management light came on Friday and there was no loss in performance and no fault codes were present :sus:. Today the battery has died on me so I decided to change it (The alternator popped 4 months ago and was changed but I kept the same battery). I thought the light may of gone off after putting the new battery on but it hasn't so I have tried plugging in my code reader again but still no codes present. Any ideas on what to do next would be appreciated.
