Sounds like you may have some ignition/O2 sensor or even cat issues , as these codes range from missfire to lean bank problems how many miles are on it? Whenwas the last tune up performed?

The transponder is not effective any longer sometimes the battery of the remote is very low which needs to be replaced

probably on google.

Could you post the actual codes please?

If you have a multimeter remove and test the fuses for continuity (OHMS) as fuses can look OK but they have blown. If your replacing fuses ONLY replace the with one of the Same colour and Amp rating.

Your car is run by computers, the computers have diagnostics and will tell you what's wrong. You can't guess faults like you have. A Professional Grade Scan Tool computer can diagnose all the computers, modules, sensors and systems in about 40 minutes. It can even record what happens and what goes wrong as you are driving! https://www.google.com/search?q=mobile+auto+electrician+near+me ..

To turn off HDC on a BMW, all you have to do is press the HDC button located on the center console. The button will have an image of a vehicle going downhill with a speedometer above it, and you'll know it's off if there are no lights illuminated above it. If you ever want to turn the system on again, just press the button again.

Since you fixed the fault by scan advice and was ok and on testdrive another limp mode came up, just check again with your scan to see what is the possible cause for it. Probably the crank sensor.

6 years different and a different series? If only life was that easy! Some BMW have a mechanical pump driven by the serpentine belt, and some have an totally electric powered pump. Just buy one for the model you have. https://www.google.com/search?q=2012+BMW+535i+water+pump or https://www.google.com/search?q=2006+BMW+330i+water+pump Rock Auto are a good suppliers, have images and different makers and 'qualities'. https://www.rockauto.com/en/catalog/bmw,2006,330i,3.0l+l6,1431850,cooling+system,water+pump,2208 ..

Check the basics first. Is battery fully charged? This is the most common reason for a no crank, no start. What exactly does it do when you turn the key? Nothing at all, no lights, no 'click' as you turn the key. A slow lazy crank?
