Ok.. i just bought a 2001 z3.Whhether this was a good dicision is debateable. The BMW dealer charges 135.00 for an oil change. Is this not robbery or do I need to learn some things. Also.. what services need to be done and how can I learn to take care of tthis car? Thanks for putting up with the ignorant.

go to BMW dealer. Show proof of ownership. They'll give you the code for free.

General advice:
Oil/filter replace.
Air filter replace.
Fuel filter replace.
Brakes/pads/oil/discs/dust proof sealers,
Timing /tension.
Valves adjust.
Wheels alignement/balance .
Tires condition/pressure.
Engine compartiment belts.
Battery/alternator condition/charge rate.
Lights alignement/hight ceck.
Thermostat open/thermoswitch triggers fan.
Coolant ceck/change.

I just did this yesterday for an M3...
pull the stereo out of the dash far enough to read the serial number... call the dealership and they will look it up free of charge and give you the code... write it on the radoi for future reference...

I agree with the previous expert.

Get the oil changed. Use what the manufacturer recommends. Your engine is designed for a specific viscosity, and you need to adhere to the manufacturer's specifications. Nowadays, oil does much more than 'lubricate the engine'. The oil moves the variable valve timing, and a host of other tasks.

Viscosity is important.

Too thin, too much volume. Too heavy, to little volume.

...Will it be OK? I would think so, but, you really need to get the right oil in it, Make Jiffy Lube change it for free. They screwed up. Not you.

Dealer thing just take the car down and they will run your vin number and door code to fix your security error code.

Greetings from Maryland. I have had issue with codes before myself, and it appears that ONLY dealers can provide proper coding, usually for free. Once they unlock and engage the radio for you they will give you a copy of the code for your use later. The odds are the NYC dealer provided a bad digit.

You can buy the filter from a dealer and buy the oil anywhere. Be carefull when installing the filter.

If the radio is displaying code wait, or wait, then the ignition and radio must remain on for 1hour. I would contact a dealer within the USA and provide them with your radio serial number. The serial number can be displayed in the radio by pressing and holding down the "M" button while turning on the ignition.

Yes. If it was bought in the US, it was coded for the US, so have a US dealer provide the code.
