VW Sharan 1.9TDi 1999/2000 - battery drain - TonyStirling

My battery goes flat over night. Even with everything switched off there seems to be a small current drain. I know this because when I disconnect and reconnect the positive battery lead to the battery terminal there is a small spark. Everything is switched off, including courtesy lights.

A couple of weeks ago the ECU was replaced (with a second-hand one) by a VW garage. Could this be the cause of the small current drain.

Thanks

Yes it could be the ECU not shutting something down correctly. Take it back. Regards Peter

All modern cars will give a small spark as the battery is connected ,so this is not really conclusive evidence that you have a battery drain.You need to get an ammeter in circuit to verify the real time parasitic drain.hth
