Hi everyone, I went through the list but couldn't find my issue. I have a 2003 745i that I cannot get INPA to connect to. It starts and runs fine and I can get a cheap $20 code machine to pull fault codes and clear them through the obd2 port. For some reason though the more advanced...

Hi all. Picked up a used BMW from a buddy. 128k miles. He bought it off an estate and it's sat for 4 years. Seems like a good little car but have some weird things going on - unsure if they're related: 1) driving with A/C on. Occassionally it will shut off, the controller will go dim and...

Hello Gurus! We own a transmission shop and primarily only work on domestic cars. Customer brought in a 2011 X5 so we took it to a specialist who said we needed to replace the transmission. Customer didn't want to pay for it so we offered him some cash for the car and he took it. We thought...

NAV screen comes on then goes dark multiple times for 5-15 minutes after starting my 2006 330i. Then it comes on. All things normal from then on. I have tried rebooting and disconnecting/reconnecting the battery. Anything else I can try before bringing it in and probably replacing the...

Is it possible to convert the OBD computer in my 1986 325e so that it will function like OBD2?

So I know there is a secret menu for the on-board computer, but I don't know how to access it or what all it does. I've searched around and cannot find the specific answer I'm looking for. Is there a way to change the "Average MPH" to "Current MPH" to use as a digital speedometer? As a bonus...

Hello All, I am new here so first I wanted introduce myself and say hello to everybody. My name is Adrian and I am a fresh owner of a BMW Z4 35i (2010). Since I bought the car I am experiencing some weird behaviour: 1) Sometimes (1 in 60) the car won't unlock using the remote key - I need to...

Hey All, Long time BMW owner, first time poster. Title says most of it. I went away for Christmas break for 3 weeks and came back to find my computer (with the mileage, temp, etc.) blank (light still on, but blank). The car still works fine so I think nothing of it. Fast forward 2 days and I...

I bought a BMW 328i from a guy who purchased the car from an auction. The car did not come with a key from the auction. So the guy I bought it from, purchased a BMW key but he never had the key coded to the car. Therefore, I can not start the car. The car's engine had almost everything taken...

I have a '99 Z3 2.3, and my battery will run down over the course of about 2 weeks. To trouble shoot this problem, I first determined that the total draw on the battery was around 237 milliamps. I then checked individual circuits by measuring the current across the fuse sockets. It happens...

Hi, I'm new to the forum so please excuse anything I do wroung. I recently just got a 1984 BMW 318i and after charging the battery, it worked--for a while. I couldn't go above 1st gear until I found that the gas pedal cable was loose. I fixed that and it revs high. The owner before said that it...

Hello everyone, this is my first posting as is probably not uncommon, I have a problem. I have a 2004, 154,000 miles. This is a strange problem, because it seemed that more than one system failed it once, or at least very close in time. I was several hundred miles away from home (doesn't it...
