Question about BMW 535i

Bmw 535i 1997 transmission fail safe program keeps coming on

I got trans failsafe prog come up on my bmw 535... a previous owner had a bmw740i box fitted back in 2002, so i decided to get correct 535i box installed, for a very reasonable price GBP340. But this fail safe prog still insists on popping up.. after reading up on this in a forum i was advised to check alternator....which was check and seems fine and was advised to check battery as even a voltage 0.5 of a volt could cause ghost errors...Batt checks out fine It has picked up voltage erros on a few other sensors on the car to, Coolant temp sens etc also could this sensor cause my car to run cold or would it just be needing a new stat? Many thanks... Craig

Check compatibility of gearbox ECM with gearbox. You will need the serial codes of the ECM and ask manufacturer for relative compatibility with gearbox type.

    Turns out my battery wasn't fine... ment to be able to cope with a 200amp load for atleast 15 mins. Mine managed 30 seconds. lol New batt now and all is fine. Low volts caused ghost errors to arrise as the comps need a constant 12v to run properly. Many thanks for your help tho... Craig

SOURCE: 97 Dodge Ram Pick up cranks ok engine won't run

try checking all the ground circuits comming out of the PCM. and its also not common for a ground driver in the PCM to fail on dodges. also i have seen crankshaft sensors short out and take out pcm communication. so i would start by unplugging any sensor that runs off the 5v supply until the pcm wil talk to the scanner. if you unplug a sensor and communication returns to scanner then replace the sensor. and dont forget to check for good power and ground at the data link conector and PCM

SOURCE: BMW X5 Trans Fail Safe Program,

sometimes it will clear if you turn the X5 off and restart it. however, it could be an early indication that the tranny is about to expire. i have had it happen and it cleared with a power cycle, but also had friends where it cleared for a few weeks/months and returned. this time it was really the transmission that went bad. if you can't get it to clear, then i'd suggest taking it to the dealer and have them plug into it to have a better look.

SOURCE: BMW X5 Trans Fail Safe Program,

IT'S VERY EASY TO RESET THE TRANSMISION'S COMPUTER. HOLD GAS PEDAL DOWN. TURN THE KEY TO THE NUMBER TWO. CONTINUE TO HOLD THE GAS PEDAL DOWN FOR THIRTY SECONDS.RELEASE THE GAS PEDAL AND PRESS THE BRAKE PEDAL FOR TEN SECONDS. NOW YOU CAN TURN THE VEHICLE ON. THAT SHOULD TAKE IT OUT OF SAFE MODE

Transmission failsafe


from your brief description i would say your alternator has failed, which means the car can no longer recharge the battery or supply battery to the car itself.

The transmission has gone into limp mode. My Boomer done the same thing' if it wont reset itself i think the only option is a BMW dealer to faultfind. Very complicated computor controlled transmission beyond any novice im afraid.

Transmission sensor ( fail safe prog )


I have had to have my BMW X5 2004 transmission rebuilt TWICE in the last 2 years. First, @80K, it just stopped, though engine rev'd. When the trans place opened it up, they said the trans oil was burned, so they rebuilt it for $2,500. I had problems over the year and then it went again during the warranty and they repaired it, free. Lasted 14K Miles. I got ALOT of Trans Failsafe Prog lights. When I turned off the car, it reset, but ultimately came back on, and forewarned an impending trans failure. When the trans went the 2nd time, I bought a USED 40K trans from LKQ (I was lucky to find one with low mileage) for $2K and had the trans place put it in. NO PROBLEMS now. I got this advice from a BMW dealer parts guy out in PA - NO ONE can really rebuild BMW Trans well. Either go for a remanufactured one, or a low mileage used one. Getting them rebuilt at the local trans place will only give you heart aches and you'll end up doing the job again. ALSO: DO NOT WAIT FOR the BMW recommended 100K miles to replace the trans fluid. I suggest 60K. That's the #1 cause of trans failure. I'm out $6K on trannys now, but I'm about to take legal action. One more thing - I used K-Solv in my radiator, and the Trans guy told me that it clogged up the trans cooler. He took off the cooler lines and put a video tube camera up there, and yes, it showed cloggage. Jury is out on who's the real culprit here. Bottom line: Trans Program Failure is a pre-cursor to transmission failure. Get ready... Don't let a local shop rebuild it! Start shopping for a low mileage used one!

Need to know what "trans failsafe mode" message


Trans failsafe is "Limp" mode, it means a sensor has triggered due to a fault in OBC. You need to bring it to BMW or a competent shop to have a fault scan done to identify the actual cause. Limp mode allows you to drive short distance (so you're not stranded roadside)

BMW X5 2004 TRANS FAILSAFE PROG


Hi; If I get the 'Trans Failsafe Prog" message twice within about 2 hours, The SES light will go on automatically. Since I do not seem to have any real transmission problems, this SES message clears itself in about 24 hours. The "Trans Failsafe Prog" messageseems to be used to indicate other transmission problems as well, like loss of transmission fluid, so be careful. I have a 2002 X5. Cheers. Omer

It is a transmission related problem. It could be electrical, transmission or... nothing. The trans prog message cause the E34 to run in 3rd gear only, that is the reason wht you feel the car has no power. Check:
1) Turn the car off and wait 10min - 2) Main power relay, power to trans control module - 3) Gear selection switch - 4) Program switch (Manual or Auto) - 5) Computer box - 6) At last, the transmission.
