Last night the car sat outside in the rain for a good 5-6 hours. When i went to start the car, after 5 mins of ideling the damn light comes on.

This is the third time that light has come on in two months. The first time i took it to the dealer and they told me that it was a low voltage fault, they ran some tests and reset the OBD.

No light for about 10 days then came on again. brought it to another dealer and when they read the obd it gave some odd faults, so they had to call tech support. they found out that it was again a low voltage fault. Reset OBD and no problems untill last night.

What do u all think? I am very upset.

certainly not common, I run an open exhaust and even that has never tripped a service light in my Z4

you probably have a small glitch somewhere and they'll just have to run it down, sometimes this can happen to an individual vehicle, sucks that it's you but sometimes that's just the way it is :dunno

Tell the dealer you want a new car. NOW!

FOR SURE, Im so pissed off. This is the third time this has happened. Whats going on, please people help.

well... since it's only the 3rd time, i doubt your car is lemon law material, but you may want to look into the law for your particular state.

Did you leave the top down (in the rain)?

LOL, no.

Wasn't there a TSB for that? Or was it the radio resetting itself/clock not keeping the time?

Sorry forum NOOB whats "TSB"

and the radio does not reset, everything runs fine no signs of powerfailure.

TSB = "Technical Service Bulletin" IE: Something from BMW to dealers alerting them about a known problem and the corrective action to take.

alrite made an appointment to get it fixed thurs.

hope they nail it down for you, overall mine's been very troublefree

Ok I got the car back from the dealer. W00T

Repair Order said:

THIS FAULT IS NOT CURRENTLY PRESENT, AND REQUIRES NO REPAIRS. CLEARED FAULT MEMORY OF THE VEHICLE AND ROAD TESTED TO ENSURE THAT CHECK ENGINE LIGHT DOES NOT COME BACK ON.

I was told by the service advisor that this usaually happenes on the M cars.
Has this ever happened to any one?
What are the DME and EPS MODULES?

Light came on again today!!! :mad:

When i picked up the car the service advisor told me to take it easy, to see if the fault comes up again, because sometimes it can get the fault during hard driving, something about sensors thinking that something went wrong.

Today, pulling out of the garage i suddenly loose power steering. after 20 seconds or so it comes back, 30 seconds later the light comes on. :mad:

So i immediatly call my service advisor. he tells me that there is definatly something wrong, probably with the powersteering servo. he said he is going to call tech support and see whats needs to happen.

Something is not right ... extreme driving is not supposed to cause a check engine light unless there is a loose wire or somethign that would be broken during heavy G forces.

something is for sure wrong, i had the car back for less than a day and the light came back on. i just hope this gets resolved quickly.

That's got to be so annoying...

Have you thought about getting a little more... aggressive? Not in the physical way, but in the «my lawyer will get back to you monday if you don't lemon-law it and sue your pants off» way...

I don't know the law in CA, but in NJ if a dealer is not able to fix the same problem after having 3 chances, the car is a lemon, and they must give you a new one or give you enough cash to make up the difference between your car and a new one.

My wife had a Pontiac with an oil leak and, while the service guy was shrugging his shoulders for the third time, I told him it was his last chance. The intention was to get him to fix it, not to actually go to court, but he didn't seem to care.

After talking to a lawyer, typing a letter, submitting receipts, and signing a few forms, my wife had a $6,000 check from GM.

That lemon law should be modified for GM cars because three tries is generally what they need to figure out what's wrong. Fixing it is another issue. :D

:laugh True. After the fact, we found out that it was a very simple problem that had been documented and corporate had sent out memos telling dealers how to fix it. It was purely the dealer's fault, but that's the nice thing about the law. It forces them to have to deal with the problem and find some way to get it fixed.

If I was a dealer, I would be contacting engineers at corporate headquarters by the second incident and asking them to offer some support.

well its hasent been the same problem for 3 times. the first two were for low voltage fault. the 3rd and last time (hopefully) is for steering angle sensor. i will give my sales advisor today to see whats going on.
