I have read a lot about problems with error messages and such when you put LEDs in your BMW. I replaced all my interior lights and also did the Angel Eyes and was also getting the error messages. I read that it is caused by the bulb check system and you can code out this function. I decided that I wanted to keep the check function, so I went ahead and replaced as many LEDs in the car as I could. I read that the error is from the minimal amount of power the LEDs use on start up. But here is the funny thing.When I replaced as many LEDs as i could I now no longer get these error codes. Could this be because of the quantity of LEDs now draw enough power to negate the error check function?.

Interior = 11
Gauges = 5
Angel Eyes = 2
Fog Lights = 2
Fog Light Bay = 2
Rear Lights = 6
Number Plate =2
Interior Ambient Lighting(Doors and Console = 4

I would be interested to know if anyone has an answer for this or has had the same thing happen without coding out the check bulb function.

You can buy LEDs that come with resistors to simulate power draw from their incandescent bulb counterparts. They'll allow you to retain check bulb functionality and won't require coding.

It seems that some people cant read english! I was asking why I would not continue to get error codes without resistors on the bulbs I have.And I do know about bulbs with resistors, I just wasnt using them. I am asking could it be possible that the amount of LEDs I have could be drawing enough power to negate the errors. Is that simple enough?:

No.

Not all circuits have cold or warm bulb check.
The system is measuring current draw.
Pictured are both BMW OEM bulbs, a halogen and a SMD LED.
These bulbs are used in the interior footwell/door.

V x A = P
Where:
V = Volts
A = Current (Amp)
P = Watts

Halogen 12V 6A
12 x 6 = 60 Watts

LED 12V 160mA
12 x 0.16 = 2 Watts

So to have a current (A) of 6A the LED would have to be extremely inefficient or physically bigger than required.

The LED purchased must have resistors if no lamp warnings are observed or be on a circuit which is not monitored.

Go a bit easy on the the first reply - he was just trying to help.

My car has the LED + light package, so appears to have all LED lighting stock. Maybe it's an option that doesn't need coding - ie. once you add enough LEDs, and the resistance in the system becomes low enough the body computer assumes you have the LED light package and switches settings? Doubtful. Ken's answer seems most likely.

You'll make lots of friends on here being a dick to people who are trying to help you. He may not have answered the specific question you asked but he was trying to provide a solution.

Sorry, I misread your post. At least someone else answered your question

Now that was the intelligent answer I was looking for. That was what I was assuming that the system is tricked into thinking that they are drawing enough power. As you stated with the LED package and LEDs in the newer model BMWs there had to be a reason for no error messages now

Thats OK, sorry Im was a bit harsh, but took offence to the SLOWPOKE remark.

Definitely no resistors fitted. Just a cheap chinese buy before I went ahead to pay a premium for workable lights. Just seems I dont have to now as have been fine for 7 mths.

Mother and Daddy issues aside,! Synthetic Heroin, Cocaine and the mention of Gram! Psychology would dictate there are other issues here to be dealt with first, Dont you think?

Right you are Sigmund.

Allow me to enlighten you. Anything that you see below the line that is displayed in users posts are called signatures.

I'm going to chalk this up as being new and not fully aware of how things work on here just yet. Welcome to the forums and please understand that most on here will go out of their way to assist with any problems or questions you may have but we also ask that you show proper respect to those doing so.

I would also highly recommend staying out of the political forums.

WOW, Big numbers! (rep, posts)/ I thought this forum might have been troll free, but some ppl need to have a purpose in life. your dream of one day owning a Bimmer wont come trolling forums. i would work on knowing what I drive,what my name is and where I live before passing judgement?
