  check your battery connections.  A loose terminal when cold can cause this.  Your computer is loosing the adaptives for fuel control.  Because your  car has no accelerator cable, they are two sensors one at the pedal and one at the motor that talk to each other without proper grounding and current they will not work causing limp mode.   When it is in limp mode the car should sound funny almost running poorly.  Sometimes the adaptives need reprogramming.  Good luck.  I need more info

Engine won't go over 5-10 MPH


You need to take the car to the dealer, because you need to recalibrate the electric throttle body with a TECH 2 Scanner, because the system went into a Limp mode.

I have a 2005 BMW x5 as soon I start driving, my abs light, my brake light and my 4 by 4 light are on and also the dsc is not active


Hi This sounds like a DSC fault more than anything, have you any fault codes? have you fitted anything new to your vehicle recently that is made by someone other than BMW?, you could try unplugging the DSC unit and having a look at the plug for corrosion on the contacts, ( this is the same as ABS module located on left hand side near head light on normal car under bonnet/hood should be same for yours) also you can have a look at the throttle body connector for same thing corrosion on the contacts, just clean and see how that goes, but check to see if you have error codes in the ECU/ECM just something for you to look at please contact me for anything else...good luck

BMW 2001 X5 has intermittent ABS light illuminating. I have changed brakes and brake sensors. The service people are unable to tell me what the problem is via diagnostic computer. What should I be...


BMW MODELS AFFECTED: All with ABS

FAULT: ABS warning light comes on intermittently. Normal troubleshooting procedures find no defect.

Possible Cause: If car has recently had two new tires, or snow tires put on. Sometimes when the car is driven over 50 MPH.

Solution: Check all four tires on the car, make sure they are the same brand, style, and size. Check if
any of the new tires have substantially more tread than the rest. These differences may cause enough
variance in rolling diameters to confuse the ABS control unit, which in turn, gives a false signal to the ABS
warning light.

If that is not the issue, it is most likely the ABS control module failing.

Have replaced ABS module on bmw 525 E39 and ABS now ok, but the ASC lamp will not go off on the dash and fault code 23 (incorrect coding) will not clear from system? Everyone told us the ABS ecu does not...


ABS/ASC module is faulty
CLASSIC ABS FAILURE SYMPTOMS:
- Most of the time, the problem is the ABS module or one of the 4 wheel speed sensors (& sometimes the brake pressure sensor)
- In my 2002 BMW E39 DSC, three orange (warning) cluster display lights lit, ABS, Brake, & DSC
- The 3 warning lights reset when the ignition is turned off, only to repeatedly reappear within minutes of normal driving
- The fault is often intermittent leading you to falsely believe you've resolved the problem (proper diagnosis is important)
- Sometimes the fault only appears when the engine is hot; other times only at speeds over 40 mph
- Carsoft may erroneously show a rear speed sensor failure; but just replacing the speed sensor may make no difference.
- All the work is in correct diagnosis of the problem; parts replacement is trivial (from 1 to six bolts in a few minutes)
- Hence, this BMW E39 ABS 3-warning light DIY will concentrate on understanding and diagnosis of the problem

BMW (e39 1999) eml and asc lights and in limp mode


Check the ABS brake sensors in your wheels, if they are not functioning properly. It will trigger the computer to engage the ASC auto stability control light as the asc uses the brakes to assist in control. I will also engage the EML engine management light to slow the rev point to limp mode

When the DSC Dynamic Stability Control light is ON your traction control is OFF. It will sometimes trigger the ABS light and the Rev Limiter it is an engine protection FAIL SAFE mode.
Check your brake switch on the brake pedal, this sounds like the problem wen replaced it will reset the Rev limiter, if the ABS light comes Check the wheel sensors

Transmission intermittently goes into the limp mode


You need a code reader. It does sound more like an electrical prob than a trans failure you could rebuild the whole trans and it just does it again. Invest in the full shop manual including the electrical one. I would get on the BMW fanatic forumns,
