Fog light bulb replacement on E70 DIESEL
 

I am trying to chgange the bulbs in my E70 so that they are not so yellow compared to the HIDs. Found the DIY for the fogs but on the passenger side there is some kind of box behind the pullout grille.

Anyone got a solution for this, how do I get in there to get the bulb out? Or is it through the fender liner?

Strange not sure on the Diesels. My 4.8 was too easy. Pull front mesh plates out reach up and turn. On the Driver's side there is the cooler in front but nothing major. Just worked it out. On the passenger side there was nothing getting in my way.

I searched some more last night and this has come up a few times and seems to be a diesel specific problem. Some actually loosen that bumper cover to get to the passenger side fog bulb. Not a very elegant solution but thus far the only rhing I hve seen.

I wonder if the painted surround that holds the grille in place could be modified so that it can be removed as well, That might give just enough space to get in and pop the fog bulb out?




When

I'm curious which bulb you're using to get close to the HID and how it turns out when you solve the fitment issue.

H11 Cree 20w projector led bulbs. Is what I used.

loosen the screws that hold the bumper in place along the bottom and hope your hand fits. It's the only way I found to do it. I hope you have smaller hands than me cause it was a pita. I don't know who's idea it was to not be able to repair simple things like bulbs. :rolleyes:

Edit...I should say remove the screws along the bottom of the bumper and around the wheel well. Loosening them won't help you much.

That 'box' is the Active DEF tank and associated plumbing. It takes up most of the space between fender/bumper and the fender liner on the passenger's side. Be careful. DEF is pretty messy.

Thanks for the pointers. I guess this is going to be a bit harder than I thought. The placement of the DEF tank was probably not part of the original design brief and it turned ugly...

I want to do this as well but I have huge gorilla hands I couldn't even do my AE myself :( update us on how you do it and any tips you have.

How well did these Cree bulbs match the HID headlights? I'm assuming it's simply a bulb swap. Have a link to these?

SoCal the OEM HID is 4300K these Crees are very white they match the 6K HIDs which I also installed. Some Newer cars are using 6K bulbs now so I went to 6K D1S bulbs as well.

I will PM you where you can get them.

can you send me the info as well?

Those look good any link to where you got them?

I would like to know as well.

I will send out a PM to the people I purchased them from. The LED's should use a resistor but I do not. I coded mine out. The resistors they currently have gets hot so I would source another resistor from someone else until they can resolve their issues.

Before I had mine coded I didn't mind the error but that is me. I tried their current resistor and I had some problems with it being hot. BMW from 07-current seems to push more voltage to the resistor than in the previous models and gets them hotter than I am comfortable with.

I will send my name to you in PM to let them know I sent you.

The Link was H8 Bulbs to show you what they look like. They come in H11's for the FOGs.

Better Pic of LEDs and AE's
 

Here is a better PIC since I just got my SUV back today.

Real list is obviously brighter but close enough to represent color and intensity.

Did you get an error code with these bulbs?

I coded out the fogs. But they do get an error otherwise. The resistors that I have tried get too hot and I don't trust them yet. I will have to try better resistors and use the old connectors and see how that works. I can code and recode so that isn't a problem.

The error before I coded didn't bother me that much. The GPTHUNDER 7500K did not throw codes.

What is involved to have the error coded out?

Having someone code out your car. I have a guy for you if you want his info. He can remote code. If he wasn't handy I wouldn't even bother since its just a minor warning and then goes away.

Resistors will work too. Have to find some that don't get too hot. Will have more time next week to check the resistance requirements.

on the passenger side, just feel for the socket and twist off, if you have really big hands it may be harder to take out, so get a friend with smaller hands to twist it out for you. no need to remove bumper really.

I have HID fogs on all my cars :D On my 3.0si it was too easy, but on the 40d it was a bit of a pain. On the left I have a radiator for the towing capacity increase option, and on the right the box. Fun.

Managed to get the fog light bulbs in a few weeks back when I changed the wheel arches. The wheel well liner on the RH side can be undone easily enough and provides just enough space to put the bulb in. The drivers side is easy through the front grill opening.
