error codes on my 2000 528i sedan .....P0500

Resolved Question:

Hello, I am willing to TIP EXTRA for a good answer on the speed sensor/Smog issue. thanks!


I am getting two error codes on my 2000 528i sedan that are very confusing. P0500 is the main one I need help with. I know its the speed sensor......I have a scan gauge II i hooked up and It gave me the codes. The speedometer reads 15mph at a standstill. I've read some bad things online, such as getting this car to pass a smog test will be impossible. I know the part is only like $30. Any insight that will help me? Oh, and the check engine light, abs, and a few other lights are on....the one that looks like a car and the headlights....one headlight seems dim and the glass is very foggy and looks like there's mould in it. I was just given the car as a gift for some work i did. Also the tranny jerks when it auto-shifts from 1st to second

I hope that you will consider a tip and bonus for the amount of info provided and issues addressed.

 

 

 

 

 

 

 

 

 

The check engine light is on because of p0101 and p0500

 

p0101 indicates a problem with the mass airflow sensor, it is likely bad, but you can also try cleaning it.

 

p0500 is a vehicle speed input problem.

 

the abs system is what provides the speed input for the car and for the speedometer so the problem lies in this system.

 

the fact that your abs light is on also means that there is a fault in the abs system (and this fault is what is causing the p0500 code and the speedometer problem).

 

There are two very common things that cause the abs light, a faulty wheel speed sensor or a failure within the ABS / traction control module itself.

 

You will need to have the fault memory read from the car using a scan tool that can access the abs system (an obd2 tool cannot read directly from the abs system) to determine exactly what your issue is. If a wheel speed sensor is determined to be the problem, then you will need to replace that sensor (about $150 - not $30).

 

If the module is determined to be the problem, then the module itself will need to be replaced or sent out to be fixed. Two good places that fix these are Module Masters and BBA Reman. You can find both on google. They charge about $300 to repair one of these modules. Replacing the module with a new one will cost around $1000, so sending yours out to be rebuilt is the best option should the module turn out to be the failed component.

 

Again, you will need to have the fault memory read from the abs system to confirm 100%, but chances are the problem is either a wheel speed sensor or the abs/traction control module.

 

Please be sure to drive carefully as you do not have ABS or traction control functionality on your vehicle if these lights are on.

 

As for the mould in the headlight, it will need to be replaced, the seal is compromised letting moisture in. I would consider looking for a used replacement for both headlights.

 

As for the transmission, I would have the fluid checked and fault memory read out. There are also software updates available from BMW that may help. It may be though that the transmission has been neglected and is in need of an overhaul or replacement.

 

as long as you get the check engine light off (so address the abs problem to cure p0500 and the mass airflow sensor problem to cure p0101) then the car should pass smog.

 

I hope that is helpful, please let me know if you have further questions, or if I can clarify anything for you.


It has been my pleasure to help today and I wish you the best of luck with the vehicle.
