1991 BMW 3 Series Questions & Answers
What cause brakes to fail and not responding at all ???
Brakes fail due to low fluid or air in the lines (usually from low fluid).
The airbags and coolant are not related to the brakes.
Have you hit some thing ?
A wiring problem could affect all three, possibly a common ground between the three ?
but you will need a "competent" tech to look at it.
Tapping noise
blown or clogged oil pump. The tapping noise may be a bearing or lifter, I would not run it until problem is fixed, you could blow a piston rod out the side of your engine. check the oil pump to see if is operating. if not, replace.

Went to start the car
Try jump starting, see if it starts then. Lights, radio, etc.. don't draw nearly the amps that your starter does. Batteries don't always give warning when then decide to "go south". If you can get it started by jump starting, stop by a local Autozone, Advance, etc.. auto parts store and have them do a charging system test and to load test your battery. They offer this service for FREE
Another Note: When was timing belt last replaced? If it's a 325 of that year it should be done every 60k (If it's 318 ignore the above belt issue)

Some idiot so called mechanic has forced the wrong
Likely, the plugs weren't cross threaded but I'll bet that anti-seize compound wasn't used. Plugs are not replaced as often as they once were and the dis-similar metals tend to corrode and bind so you end up tearing the threads out when you remove them. (doesn't matter now, result is the same). You can use heli-coils to do the repair...likely you can have them shipped if you buy them from an on-line source. Only problem is that you may not have enough room to actually do the install. As far as reliability, heli-coils will hold up indefinitely...Used them as routine on 7,000 hp fuel engines having very high cylinder pressures and never had one fail.
If you can get to them, you need to put a vacuum nozzle near the holes as you are drilling.(Removing them, they either will come out with the threads damaged or snap off....need to be drilled to accept the coil so that doesn't matter either) That should prevent most of the debris from entering the cylinders. Once drilled out and tapped, crank the engine over (ignition disabled) to blow any that did get in there out.
Other than removing / replacing the head, that's your only real option. And, of course, after making the repair, use anti seize compound so it dosen't happen again!!!
Good luck!!

1993 325I BMW LIMP MODE NEED HELP
Hi badboyf6,
Limp mode can be activated by many things to numerous to list here so, if possible can you get a local mechanic to hook up an OBD lead to the ECU (computer thingy!) of the car and read the fault code.
From this reading he/she will be able to determine what has caused limp mode activation and depending what it is reset/cancel limp mode.
Gettin a fault code reading is quick and cheap to do, (even from the dealership!) and at least you will have more information to determine what is best thing to do next...
Hope this helps and good luck.

BMW 3.18i - damaged electrics and now I've lost 1st gear.
go to salvage yard they are more than happy to sell you the parts you require and are more than willing to look at pics with you and identify the parts required
they will likely have the car unstriped there also so you can see the parts you need and can just point them out

I have 1991 vmw 325 the light are blinking
If you mean that all your lights are pulsing from their usual brightness to slightly dimmer then back, then this is usually a sign of bad voltage regulator in your alternator. Most alternators no longer have an external regulators so alternator needs to be replaced. To test this turn on your lights and pay attention to how fast your lights "pulse". Rev the engine and if the pulsing speeds up then its your voltage regulator.
If you meant that a specific light keeps blinking then please specify which and during what conditions, and we can try and get it figured out.
Hope this helped.
