Appreciate any help, I have a problem with a battery drain & headlight switch, been having to disconnect battery every 2 days, battery been replaced keeps charge ok when disconnected. Model a3 1.8T 51 plate, fuses all good.. I have sourced a second hand light switch from audi a3 aeh 1.6 8v (golf bora) parts are the same I think.
Anyway connected up lights work fine now (fog lights not working) battery was low so used battery pack (halfords) to start car, now instrument panel not working, ie speedo, rev counter & oil light warning comes on but not low, also fuel gauge & temp gauge not working-any ideas please I'm not eperienced with cars but trying to learn all fuses good..
Other problem was slight jumping of rev counter when running idle..
