Depends why the Failsafe was triggered. Read the codes would be a good way to start. Anyway, since the car wont start, it may be the crankshaft position sensor, which will cause a trans failsafe and prevent the car from starting.

Check for other codes. A crank position sensor failure will cause a Trans fail and could prevent the engine from starting.

Have to have the transmission problem diagnosed

Best not to use it or you may ruin the trans in as little
a ten miles & may have already, using it in failsafe

Fail Safe is there to protect the trans, but only if you stop
using it almost when the light comes on.

It will cut injector pulse,ignition spark & such, to let you
know your have a problem & lock the trans in a specific
gear,BUT folks still continue to cycle the ignition key &
drive on, to the tune of $5.000 leaving their bank account

Run the fault codes and check for TCM failure. Check transmission fluid levels

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!

Check for codes and you may need to replace trans Input/Output sensors.

That is a pretty robust transmission but its computer is very sensitive the quality of the electrical supply. If you take it to a shop, they will probably put a known good battery in the car and check and clean the electrical grounds before they even look at the transmission. If this is your original battery, you will probably save yourself some money (and perhaps a trip to the transmission shop) if you replace the battery yourself and clean any ground connections you can find. Sorry, but other than the one near the battery, I am not familiar with the ground locations on this model, though there should be a ground strap around one of the engine mounts that should be inspected/cleaned.

2003 X5 bmw the trans. fail safe program comes on when driving, I was told that the trans needs to clean out and put new sensors. Is that true it gives the code 055

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.
