the resister should be inside the blower fan housing

A lot of times you are talking about a little piece of plastic that will act as a guide or a bushing to allow for a more tight feel when shifting. This is a pic of some of the fixes that you can use to eliminate this issue. If I remember correctly, you should be able to do this from inside the car. Look for bmw z3 shifter bushings on the internet or call your nearest BMW dealer and they should have them in stock.

Most times the button is wore out. There are ways to take it apart and bend the contacts in an emergency or temporay fix. Best to replace it.

It is a vent for the battery and needs to be hooked to it.
Hopefully your new battery was the right application and has that provision.
Don't use one that doesn't

time to change the ignition relay.
it sounds like it has failed in the closed position.


Thanks!!

Remove and test the thermostat, then test the radiator for blockages.

This is usually a symptom seen when a latch mechanism has worn out. I would replace the door latch with a used one. This is the unit that actually holds the door shut. You will see it on the side of the door. The door panel will need to be removed to gain access. Let me know if you need anything further.

could be pressure switch. When the guy put 134a in...find out what the pressure readings were on the suction line to find out if the compressor was working. May as well hook up the high side as well to get both readings. If there's a decent separation between the two....the compressor works. The evaporator is just a radiator, there's a metering device for the refrigerant into the evaporator, but the only thing that goes wrong with an evaporator is a leak.

It doesn't take anything special for today's plastic radiators to crack. You didn't say what model year it was but it's not unusual after 10 years or so for it to develop a split. Of course higher than normal temp and excessive vibration or knocks could attribute to it also. A radiator shop can replace the plastic part using the fins from the old one.

A drive belt routing diagram is needed when replacing a drive belt to help simplify the installation process. The problem arises as there are many different ways a drive belt can be configured. In this configuration the belt length will vary not allowing the belt to be installed. Also alternative configurations could turn a particular accessory the wrong direction, creating more problems. Always reinstall the drive belt in the exact configuration as the previous belt to prevent these problems. Always use high quality replacement products to avoid premature drive belt failure. If a multi rib drive belt fails it must be replaced immediately to avoid such situations such as engine overheating and loss of the power steering system. Whenever a belt replacement is required inspect the pulley condition to ensure there are no sharp edges on any of the pulleys, this will cause the belt to shred and fail. Confirm that all pulleys are free from debris such as small pebbles, these pebbles will cause the belt to pit and significantly impair the belt performance. The belt tensioner plays an important role to the drive belt performance, if this tensioner is weak it can allow the belt to lose tension allowing the belt to jump and skip. This condition will result in noises such as squeaking, chirping and ticking.

Hope this help.

what year is your Z3 and what engine?
what accessories and do you have a serpentine belt or v-belts?

I took a guess
this is for a 2002 Z3 with the M43

P0301 is a misfire on number one cylinder that is the rough running, as to what the source of that is will require a thorough diagnosis, it is not cut and dry and it can be a multitude of things causing the miss, start with the ignition system, poss causes are in order of how common it is
1. Defective spark plug
2. Defective ignition coil for #1 cylinder
3. Intake manifold vacuum
4. Defective fuel injector cylinder #1
5..Defective #1 fuel injector driver circuit of Powertrain control module
6.. Engine mechanical problems, low compression due to scoured cylinder or burnt valve or flat cam shaft lobe etc..

P0170
Fuel trim lean, the unburned fuel from #1 cylinder misfire going out the exhaust is causing this problem I think, but it could be be the MAF (mass airflow sensor) sensor, I suggest u isolate the problem with the #1 cylinder and repair it then clear the codes and drive it, if the light comes back on and the code P170 comes back try cleaning the MAF sensor, many times that cures the problem.

GREAT question
However, I searched both my BMW component locator and wiring diagram and it appears the parts store may have mislead you...

Often their parts list will show every part ever made for all vehicle even if said part is not on your car

as you can see here... no shut off switch

Did you check the fuel pump relay?

Is this a factory installed alarm - or aftermarket?
Thanks!!

you need to do a cmp/ckp relearn
however, you will need a scan tool to do this
look in your yellow pages for a mobile technician
this is someone who will come to you house
this might cost a few dollars more than a regular garage but you'll save the $50 in towing fees
