    Welcome to the new forum

    I thought I was losing my mind when I clicked on my saved favorite link and it said "I didn't have permission to access the site".

    Passenger Airbag Off Indicator

    So recently I changed from grey interior trim parts to black trim parts including the Passenger airbag indicator in the center console. After starting the car I got an air bag light and code "93E6 Signal lamp, airbag deactivation: open circuit". I figured it came on because I had the indicator...

    Two VANOS Removal Questions

    I'm going to refurb my VANOS and had a couple of questions. 1. Do you think it is better to unbolt the RT engine mount and jack the engine up or loosen and pry on the crossmember? 2. Just eyeballing it, it looks like the VANOS will not clear the temp sensor housing on the lower radiator hose...

    Merry Top Down Christmas

    Wishing everyone a Merry "top down" Christmas from across the pond! You have to look at the bright side of "global warming" like driving with the top down on Christmas day.

    Lean Codes with Unusual Fix

    One day on my 2003 E85 I noticed that my average MPG was down 3-4 MPG, car was running fine, and then the next day I got the "service engine soon" light. Read the codes and it was showing P0171 & P0174 both banks lean. I also looked at the live data and the long term fuel trims were both around...

    e85/86 Specific Android Screen

    I just installed one in my 03. You have to do some trimming and filing to make the profile fit the Z4 dash contour but if you take your time you can get it to fit nice.

    Installed X3 Dash Storage Compartment

    Decided to install an X3 Dash storage compartment since every little bit of storage room helps in the Z4! It took me a few weekends to complete and was a little harder than I thought it would be. The contours of the X3 compartment is close but not close enough to the Z4 dash and it took numerous...

    Seatbacks Repaired

    My 2003 3.0 had the typical seatback falling off problem. Over the last few weeks when I had time I repaired the seatbacks with fiberglass and resin and recovered them in Alcantara. I also ditched the plastic pins at the bottom of the seatback and used spring nuts and screws for a more secure...

    Trunk (Boot) Light

    So the original trunk light in the Z4 is pretty anemic and even after replacing the bulb with a very bright LED it still did a poor job of lighting up the space. So I installed an LED light strip and tied into the existing light so that it works when you open the lid. It lights it up now!

    Boot Lid Alarm Microswitch

    I recently installed the factory alarm pieces (Hood switch, Siren, Tilt sensor) and when I was coding the car I noticed that it had an option to turn on the "boot lid contact" in the alarm section of NCS Expert. So I switched it to active but the alarm doesn't work when the lid is opened. I then...

    Roof Windshield Unlock/lock Motor Cover

    I recently installed a new $70 plastic cover because the PO broke all the tabs off and had super glued the cover in place. I removed it the other day and it was so hard to remove I thought I was going to break the new cover. So to lessen the chances of breaking it in the future I drilled a hole...

    LED's Dimly Lit When Off

    I have a 03 E85. Went to put in LED bulbs in the interior, side turn signals and boot and even with the switches off the LED's stay dimly lit. So with the turn signal on it is very bright as expected but when you turn it off it stays dimly lit, same with all the other interior bulbs. So i...

    Weird Soft Top Problem

    I have a 2003 E85 that is new to me. The top had two leaking hydraulic hinges so I never saw the top work. I had the hinges rebuilt by Top Hydraulics and relocated the pump/,motor to the trunk. When I try to operate the top (up or down) in only moves a couple of inches when I push the button...

    Roof motor RelocationQuestions

    I'm relocating my roof motor/pump to the boot. I've read all of the "how to" write ups and many, many, (maybe to many :cry: ) forum posts and the one thing I've yet to find is how the hydraulic lines routed? I've seen several different ways to drill holes to get the lines to the boot but no...

    What goes here??

    So still new to the Z4. One day I was looking in the "boot" and notice this "compartment" I guess you would call it. What is stored there??

    Cabin Air Filter

    What's the best cabin air filter for the E85? most of the ones I've seen are too rigid to be inserted all the way.

    New BMW Owner - 2003 Z4

    Just bought a new to me 2003 Z4 3.0 6 speed with about 90K on the odometer. It drives pretty good and the exterior looks good but the interior needs some attention. Look forward to learning a lot from you guys!
