can anyone help??????????

OK heres the problem i have a Mk1 disco and have fitted a set of hid headlamps to her everything seems fine until last week  sometime when i flash the headlamps or when i turn them on the hazards switch on and the doors unlock. i know that there is a sensor for impacts and that it will do the same as is happening here so i have two questions 1 does anyone know where the sensor is?
2 does any one have any thoughts how to stop this problem? it is nice to be able to see the road a night now  :dance: but not with hazard's going

The sensor might be in the front panel somewhere, it's not the SRS sensor thoguh is it?  The HIDs use a solenoid to dip the lights, they go with a bit of a thump which could be picked up by a shock sensor.

whats the srs  sensor?

Airbags, mine are orange and bolted alongside the battery/spare battery tray.

Later cars they wer eincorporated in the SRS ECU in the glovebox area.

However, your pron;lem is to do witht he central locking I think, some folks had problems like you describe when off-roading.  IIRC the Central locking ECU is under the dash on the passenger's side.

OK the only problem is that i don't have airbags fitted . does the ecu control the hazard and locks in the event of a accident?

IIRC the central locking is designed to flash the hazards and unlock the doors if it thinks you have been in an accident, I don't know where the sensor is but I'm thinking that if the hazards fkash and the doors lock/unlock when you change the dip/main on the hids then that could be the cause.

I didn't know if you had 200 or 300 TDi, the 300 would have had airbags, the early ones have remove airbag(SRS) sensors like my Soft dash, later Discos had the all-in-one-box system.

But that doesn't apply to yours anyway.

To answer your first question, I suggest using rubber gromets to isolate the mountings of the headlights so that the shock is not transmitted.
