Post by: 87 velo on August 30, 2013, 11:26:55 PM In some late model cars, the engine management system controls the alternator output (Audi amongst others) so if the battery is dead flat, or you disconnect it, you need to tell it what type of battery it is before it will go. This requires plugging it in and and communicating with a gadget you probably have, so when in doubt use a memory minder (goes in cig lighter with a 9v battery) or get cunning with jumper leads! And save yourself some drama! This kind of set up is becoming increasingly more popular with manufacturers as they look to improve economy and emissions, system voltage effects how long it takes injectors to open, earlier EFI systems monitor voltage for that reason but they have found it better if the ECU controls it.
Goodluck |
