Warning lights and power issues
Hi, i'm hoping someone can help.
I've got a couple of issues with my 2009 R56 Cooper D 1.6.
I have fitted some aftermarket HID lights to the vehicle (whether these issues are related or not i'm not sure) and it is only since then that the following issues have occurred:
The other day I parked up at a car park and turned off the engine using the start/stop button, when I went to turn it back on there was a complete loss of power and nothing was on at all not even the light was on when I opened the drivers door.
A few minutes after this happened, the dashboard below the rev counter was really dim and came up with the airbag light and also the car on a ramp symbol which was red and then the power went off again. I managed to fix this issue by pressing one of the battery terminals down under the bonnet which then made the power come back on.
This same issue happened again when I drove to my next destination but this resolved itself and I didnt need to press down on any of the battery terminals.
The second issue is that while driving the car this evening, the headlights flashed and at the same time, the power steering light came on on the dashboard and the car felt like it was about to lose power. This happened twice but again resolved itself.
Please could someone advise on the above as to what could be causing these issues to occur.
Kind Regards and thanks in advance,
