Sounds like thermostat went bad. That would explain cold one side/hot other. I'd start there. Good parts sources - BavAuto.com or PelicanParts.com

You need to get hold of a tool to read your supplemental restraint system (SRS) codes. Fortunately, for 2002 models, tools are commercially available for a fairly reasonable price, or you can visit a shop that works on BMWs and have them check it.
Often times, airbag codes result from someone abusing a seat belt buckle or from something heavy bouncing on the passenger seat, confusing the occupant sensor. If you just reset the light (which the code reader will do) it often will not recur. If the light comes right back, you have a problem and you need to get it fixed. If the light is lit, they air bags may fail to deploy in an accident, or they may all deploy in an accident (which would total the car and be really hard on your eardrums) The code should give a clue as to where the problem is.

Look up your car on RealOEM.com. It shows the belt position and shape when installed.

most likely its the thrust bearing noisy but it could also be the layshaft bearings in the gearbox as well ,check the gearbox oil level and check its ok if ok then its a thrust bearing ,these modern motors with a nylon bearing holder are not very good to say the least ,now if oil level is low in gearbox then before you top level up use a grease gun and remove the nipple thing on the end and then pump a good grease gun full of LM grease into gearbox and then top up with EP90 as this will help seal any leaks and stop a lot of the noise ,you cannot hurt anything by putting the grease in the gearbox i do it lot to stop a leaky gearbox from leaking as the grease gets hot and sinks to the bottom and solidifies stopping a lot of the leaks from gear linkages and around the drive shafts although this is a rear wheel drive vehicle so that is less of a problem

Sometimes (as weird as this sounds) trunk actuator will knock sync out if whack. (I used to work for BMW and encountered this once before) Try working locks from trunk actuator. Can also try from passenger front door.

The first thing to do is clean the crankcase ventilation system. That may not turn out to be your problem, but you don't want to pursue other diagnostics until you are sure that the crankcase ventilation system is clear.
I am not familiar with the 316 so I cannot tell you how much work it is to get the plumbing off to clean it. I recently did my '04 325 and it was a real PITA. I have done clutch jobs that were easier than that.

Sounds like a VANOS problem. If you have $70.00 (American Dollars) and about 8 hours of time (at most) you can replace the VANOS seals. Here's a place to buy them:


You might as well change the valve cover gasket as well since you have to take the valve cover off to access the VANOS.

Hope this helps!

I am having a difficult time interpreting your question, but there are instructions on my website for repairing an e36 climate control that show you what it is supposed to look like inside and outside. Perhaps that will help. http://www.frontiernet.net/~papi/Clim_Ctrl.html

I'm not sure about the BMW, But most cars I've done is to turn on the ignition, push the gas pedal slowly down to the floor three times within five seconds. And this will reset the oil light. Good luck

It's very likely the air filter. if you haven't changed it recently, that would be the first thing I would start with.

If you have recently changed the air filter, my next guess would be for you to have the, " idle air control sensor " checked.

Both of these are very common for the isuue you are having.

I hope this helps you.

The most common causes are:
1) Something bouncing around on the passenger seat confusing the occupancy sensor. 2) Someone jambing the seat belt buckle together at an odd angle. The older e36s were notoriously sensitive to that. 3) Someone has been working on the seats or the doors and turned the key on while something was unplugged. 4) Something is actually wrong in the system (rare).
The normal response is to read the code, reset the SRS system, and see if the light returns. Usually, it won't.
The bad news is that BMW changed their SRS system in the 2004 model year, and the aftermarket scanners won't reset a 2005. The dealer may gouge you to reset the light. A well-equipped independent shop can do it.
When I foolishly turned on the key to test my work on a window regulator on the wife's 2004 330, the BMW dealer wanted $180 to reset the SRS light. My favorite independent mechanic reset it for free. I took him a box of pastries from my favorite bakery.

Wow this I recently delt with, there is a weird way to reset what bmw calls the lockdown mode or something like that, you use the key in the passeger door in a certain way. find a shop with michell1 or call the dealer and they should be able to tell you. but this is only if you particular car has entered this manuel lockdown mode. I found this strange as the bmw i was dealing with according to mitchell1 actually manually takes the door lock linkage apart in the lock assembly so that the alarm computer must be reset for the locks to function even manually!!

your asking me something now ,havent seen one in years but the cables can be connected over with time and patience and a bit of solder is good as it doesnt corrode ,now the ballast resistor fitted with the siemans was a different type of circuit and as it was a bosch then wire it as the bosch was wired ,because the ballast resistor was used in conjuction with a 9v coil and when you cranked the engine it allowed full 12v voltage to the coil to give an increased spark under crank load ,never did work that well to be honest and the resistors often packed up so use it as the bosch system .On the siemans you had a wire from starter connection on ignition switch to coil and the ignition feed went through the resistor to the coil ,Simple enough but them resistors were a right pain in all honesty
