E85 Light problem - double speed indicators

[Benjamin547]

Morning all. I’ve got an issue with my right indicators. When I indicate right, i get double speed indicator. The left side is absolutely fine.

I’ve checked to see if all of the bulbs are working when I indicate right, and they do (front, back and side). I’ve also checked the hazard lights, and they work perfect at normal speed.

So.. I did some research and replaced the lights switch module. Literally replaced the module switch that turns on your headlights, controls the dip of the beam etc. That didn’t work.

Has anyone else had this sort of problem? Any help would be appreciated.

Have you tried replacing all the bulbs on the right side, just in case something weird has happened to one of them (i.e. it lights but has a high resistance ?)

usually the sign of a poor earth - suggest you check the holders themselves and the earth connection of the light cluster-
Try attaching a separate earth and run the indicators to see if they work normally

Don't forget the head lights have two indicator bulbs, could be just one of them that has blown.

I have the 2xcite headlights, and I thought they only had 1 indicator bulb (I could be wrong).

Sorry, can't vouch for the 2xcite headlights.
Have you got any closed to finding the fault?

I also have Sonar 2xcite headlights. They definitely only have one indicator bulb. Have you physically withdrawn the indicator bulb holder from the rear of the light unit ? The bulbs are sometimes a very tight fit through the orifice and can be twisted slightly when fitting and not make full contact in the holder. Also, have you wired the 'eyebrow' bulb into any other such as the angel-eyes or the small central LEDS or the indicator ? Do you have any LEDs fitted in any of those places ? From my experience the Sonar lights do seem quite sensitive to particular bulbs or LEDs. As a last resort check the multipin connector block where the headlight unit is plugged into the existing BMW connector as these can corrode or be a bit temperamental. Unfortunately, if you can't get to the connector block through the wheel arch access panel then you may need to remove the front bumper to get to them

The Sonar/2xcite headlights also have a load resistor under the headlight.

Thanks for the help guys. My local garage are helping out with an auto electrician. I’m hoping it’s nothing too crazy, and easy to fix. I’ll let you know what the outcome is. Thanks again, I’m really grateful for the advice and support.

Hi Ben,

Would be interested to hear what happens, my car randomly started doing this exact same double speed only on the right indicator, but with original headlights. It works normally on hazards so I assume that means the problem isn’t with the light itself?

Not necessarily, have you checked both bulbs?

It was only on the weekend that I realised there are supposed to be 2 indicator bulbs on each side!

I also found an old thread describing my exact issues as well, on a 50 mile drive the other day the issue came and went whilst using the right indicator.

If anyone is digging into the same issue this is the thread:

I am yet to catch it with the warning light off and the chance to get out and check the bulb is working.

The issue for them was LEDs, which I had for the side lights and all of this started when the left LED went. Once LEDs were removed the problem slowly went away (fault came up less and less).

For now I am going to see what happens. If the fault is still popping back in a couple of weeks I’ll get the indicator stalk out, clean the connections and check the bulbs.

Check the headlight harness for rust, causing bad contact and resistance

I now have the same issue. I have all lights working but the rhs indicator is going at double speed checked everything I can think of and no soloution. They are 2xcite headlights Ive had them about 10 years. I have a Lsz2 fault code on my Carly App could this be causing it? The code I think relates to the light leveling motors. Did you find a soloution for your initial issue?
