Scotty, my 2002 BMW X5 3.0i with 149000 is back again with a new problem! While driving home from work, it gave the "Trans. Failsafe Prog" limp mode message with a loss of power before shutting off. The engine turns over and wants to start, but can't. I've checked the fuses (I didn't check the Motor Sicherungen fuses yet) and they all came back good, and MAF Sensor and Air filter were good. I also tested the fuel compression which had no pressure, however, a bit of fuel came out the valve (tested twice). Despite my "Service Engine Soon" light being on, my OBD-II code reader (Zurich ZR-13 from HFT) came back with no codes. I should also note the following repairs done prior:
- New Fuel Pump
- Fuel Filter
- Spark Plugs
- Coil Packs
All these were done a couple months ago.
I have now come to the conclusion that my car has become self-aware and doesn't want to run. Anyway, has my fuel pump gone bad, or be another problem all together? Also, should I check my Spark Plugs? Thanks again!
Check the FAQ section.
Lot of things can happen. It could be your battery, vacuum leaks, starter, or ignition system . So start with checking vacumm leaks first. Second, you test the battery. Last, put starting fluid. If it works, change the ignition system. I don't know if it's right. Maybe @Mod_Man can help you a little more with your BMW.
Most likely a lot of sensors fail on these types of BMWs with high mileage.

That does not help the OP.
That didn't the answer the question.
