Thats you MAF (Mass Air Flow) sensor
Replace it and car will be fine.

Gauge temperature
Your description of the problem is not very clear. It seems as if your temp gauge does not work, or does not indicate the correct temperature.
If you disconnect the wire from the sensor unit and put it to battery negative (ground), the gauge should move to the full hot position. If this does not happen the best chance is that the gauge does not work. If it does work, the sensor is faulty. In a very unlikely situation, the wire could be faulty..
Rpm and acceleration problem
throttle sensor fault. might be cleanable if removed. also could be a damaged idle valve, might be staying open this cal also give high revs. and tap and it will go down as its sticking. acceleration is the throttle sensor i may have blank spots. removing it and spraying in the switch breather hole and shake the cleaner around and turning it at the same time should clean the sensor. then shake and leave to drain out the cleaner. idle valve you will need to remove it and clean ti with some carb cleaner and a brush like toothbrush, clean it thorley out push the pin in and out to make sure its not sticking at same time spray it. then when clean leave to dry. then refit them. hope this helps
Bmw 320d e 90 wont start but it cranks
Hi Mushi, Your BMW is fitted with an anti theft system (EWS) which controls the common rail injection. I suggest having a diagnostic scan carried out and pin pointing any possible problem, which could also be related to a defective crank or cam shaft sensor. Regards John
CAR WONT START
CKP sensor or cam sensor. one goes bad and causes other to go bad. easy fix and not too expensive.
