Where are my Fuses located in my BMW E65 E66? Great question I thought the same thing, I found the fuse box location in the trunk righthand side pretty easily, but this couldn’t be all the fuses. My cousin’s Mercedes Benz W211 E500 had 3 locations so I knew there was another one. Well off I searched and bam found it hidden away in the glove box. Below in the video I show you exactly where both locations are and how to remove the fuses. When replacing fuses make sure you are replacing them in the slot location where you remove them from and make sure you replace the fuse with the SAME color & number as the one you removed. The fuse removers are located in the trunk fuse box location again watch video below for location. If your fuse remover is missing, then get some needle nose pliers and that does a great job, just don’t stick your needle nose pliers to deep to blow another fuse. The chart diagram for your fuses which fuses control which items. There are 2 charts, the one in the trunk is located on the back side of the fold down hatch that you opened to expose the fuse box in the trunk. The 2nd location is in the glove compartment the chart is folded and tucked away, on top of the latch once you open the fuse box. Watch Video Below for full details and visual. New BMW fuses here.
What is a known problem with the BMW 2002-2008 E65 E66 and also I have heard on the 5 series BMW. What most people think is a transmission problem really is the Guibo Joint or also known as the Flex Disc or U Joint or the Universal Joint. The symptoms you hear are very similar to a transmission going bad. The Guibo is located underneath the passenger and drivers seats where the drive axle connects. Right next to that is the BMW E65 E66 transmission so during rough shifts you think it’s the transmission. On my BMW E65 when pulling up to a stop sign and during downshifting from 2nd gear to 1st, I will get a jerk almost a slam, immeditilty you think it’s your transmission, so as most folks do they 1st replace their transmission oil thinking it’s a little low. I did this and replaced the Transmission Filter and put fresh Redline D4 fluid in, unfortunately the problem was still there. When replacing the Guibo you’ll be under the car, so if you haven’t replaced your BMW E65 E66 Transmission Filter or replaced the Transmission Oil then this would be a good time to accomplish this. Watching the video below I talk a lot more about the Guibo Joint aka Flex Disc and show you what it looks like and a new one and a bad one. I will be doing this full project soon, so stay tuned. Thank you for spending your time with us here at DiyE65E66.
The time finally came when I said, I’m really tired of seeing this engine light on my BMW’s dashboard. I was pulling code P0128 on my OBD 2 reader, I knew it was a bad thermostat so I took the proper measures and said lets do this. Ordered my BMW E65 E66 thermostat part and to the garage we went. I really won’t be able to describe the project as well as if you just watch the diy Bmw E65 E66 replacing your thermostat project that I have on YouTube. You can see that video below. This project was done on my E65 750i, I believe the earlier model E65’s E66’s, 4.4 Liter engines it’s easier to get to the thermostat.
Problems I faced with this project were as follows, I had trouble removing the lower hose from the thermostat, again my car is a 2006, this car has never had the lower coolant hose removed before and again this hose is slotted so don’t twist it just wiggle it again and again until you get it loose. That was pretty much the only struggle other then that back 3rd 10mm bolt that holds on the thermostat, again pick your favorite weapon (tool) of choice and you’ll get it.
Again other projects you should consider if you have the money at this time would be to replace your BMW E65 E66 water pump and belts, during this project examine your water pump for gasket leaks and wiggle your water pump pulley to see if you have a bad water pump bearing, also examine your belts for worn belts. Also examine your lower coolant hose as well. If you decide to replace your BMW water pump later as I will do, then you will have to replace the BMW coolant again.
Watch the video below videos speak a 1000 words, and Thank you for watching, and Happy Fixing.
