Sorry to bump an old thread. I have been researching on this site for weeks now, found some great info! But, I feel like I need to post my problem at this point.
1999 - 528it Wagon. 161,000 miles. Check engine light is on, LIMP MODE.
A couple months ago my car went into LIMP MODE on the hwy. I carefully drive it home and parked it, pulled up the E-brake, turned off the car. Released brake, started the car. Everything was fine for a couple weeks. Then one morning I go out to the car and the battery is dead. I jump the car and it will not start. I remove the battery and bring it to AutoZone and have it charged... they say it is fine. Car is fine for a while... then the radio stops making sound, alarm system stops working, door locks stop working.
I replace the amp, fixing the radio. I found the central locking fuse is blown, replace it. Re-program keys. Car is working fine. Although the Check engine light has been on for months.
So after all that, now my car is in limp mode. One morning I go out to the car and it's in LIMP MODE. I go to autozone and have the battery tested. They say it's at 40%, so I have them charge it up, they say its fine. I install it. Does not fix the LIMP MODE. A couple days pass car sitting. I finally drive the car to Advanced auto and have them read my codes, and check the battery again. They say my battery cel is bad and it will not hold a charge. SO I buy a new battery in hopes this will fix the LIMP MODE. I install it. NOTHING. Still in Limp. I tried to reset by doing the gas pedal for 30 seconds, then brake for 10 seconds, shut the car off. Nothing.
Here are the codes: P0141, P0155, P0135, P0600, P1423, P0441, P1421
Can anyone help? I am going to have my brother in laws friend (who works for the largest BMW dealership in Atlanta, he's a tech) take a look at it if he will do it. I do not trust the indy shop I was going to anymore, or the dealership.
Please help, thanks in advanced.
PS: I have searched the site and read for weeks. Just need a little help. Thanks!
