Hi Mike

I have not done any thing yet. I want to know how I can fix this problem. So far I have switched on the headlights and used the dip switch.

Hi Mike.

I have not had a reply from you yet. I have not done any thing yet..So far I have just switched the headlights on thay come both on full beam when I dip them the n/s stays on full beam but the o/s dips. Is it the headlight at fault or something else.

Hello again Richard -

I do apologise - I lost connection and just couldn't get back to you until Im sorry about that -

If I understand you correctly then - the one side dip is just staying on...when you should have both sides on dip - as selected.

It was a common fault to have continual issues whererby the n/s would not come on at all and rarely though you do get this issue.
This is almost always a faulty headlamp control module - I would suggest you just have that confirmed / double checked at a garage that knows these models - if you dont have one such near you - then a local Bmw dealer will only have to take one look at it to confirm and wont likely charge anything for that... Too - you wuld need to obtain a new module from them anyway so it may be as well to kill two birds as they say and go there - have them confirm it and then go from there. Also, they would need the cars VIN to Id the part etc -

Again, I suspect thats the case as you have described it - switch / wiring issues would cause faults on both sides - not just the one so thats why that leads me that way..

Let me know if you need anything more on this at all -
