Hi All

Been having problems starting my partner's car (DS3 1.6HDI) for a while now, changed BSI, and ECU and Key did exactly the same (nothing) changed the immobilizer coil, same, only thing I haven't checked is whatever comes next after coil to ECU.
Anyway, the problem I have now is I bought a Julie emulator and fitted that, Bingo, the car starts BUT wipers and lights on all the time and remote doesn't work maybe other stuff.
So do any of you brainy peeps out there have any ideas?

Thanks

Turns out it was the comms unit all along.

Just for interest which ecu ?
