1993 BMW 3 Series - Page 7 - Answered Questions & Fixed issues

If all windows stopped workin at once it's a relay ... You can usually find them under your steering wheel ... You more than likely have to remove the panel under the steering wheel and you'll see them... I forgot which one it was but call a BMW dealership ... And let them know what relay you need...

In your owners manual it will tell !

BMW CUTS OUT

A few things to check.

1. Is fuel pump delivering enough fuel.
2. Is injectors clean. Perhaps dirt in fuel. replace fuel filter
3. Air leakage at top air intake of manifold at ICV idle control valve. Two hoses inside this housing prone to perishing.
4. Throttle position sensor faulty.
5. Mass air flow sensor faulty.
6. ICV faulty or dirty. comon fault on older e36.

Havent done it yet but ICV is easy to clean according to internet. instruction available at bmw e36 blog. All off above can be tested by yourself according to manual.

if you go to the dealer they will copy the mech manule it you ask them as they want you to get frustrated and take it to them
so go on and ask and if all else fails take it to them or goto local parts store like auto zone they can preint it off too
dealer is best bet though

in any good librairy you can loan them

This could be fuel filter clogged and/or impurities in the fuel system, fuel injection not adjusted properly or faulty coil. Hope this helps.

YOU NEED TO REPLACE THAT COPLETE HOSE ASSYMBLY ABOVE RADIATOR

look for a fusable link strap or a big fuse burned or a burned wire under the box

You just pop it out, use a screwdriver with a tape on the end of it so you wont damage or put any notches in it

Latch under the hood, Drivers side of the BMW emblem. Lift it up and voila!

When the car has cooled down, check antifreeze level. Check fan belt and fan blade clutch. Check if it has the proper thermometer installed.Check the fan belt tension.

Richard, a 93 BMW 325i has timing chain and not a belt. Unless it has been absolutely neglected in terms of oil changes, the chain should last 2-300k miles

Check the alternator.

I would first check the back pressure of the exhaust system to make sure the system isn't restricted. If the engine is not misfiring, and you have changed the plugs and fuel filter, I would suspect an exhaust restriction. if the exhaust is ok, I would check the fuel pressure next.

Yes, it might be a fuse problem or it may be a short in the wiring in the driver's door...the wiring you can see by the door hinge when you open the door or you might have a bad window switch on the driver's door which is causing a short that is effecting your speakers.

Try checking the drivers master switch it may be bad and needs to be replaced...if it's bad none of the other door switches will work...the sunroof problem is most likely a fuse problem caused by your son when checking the fuses and either shorted one out or he wasn't looking when he was pulling it out and put it back into the wrong place next to where it's suppose to be.

simply changing the pressure regulator solves the problem , and change of mechanics

You cannot retro fit a late engine with vanos to an early model that uses the non vanos set up .There simply is too much else that needs to be changed as well. You best bet is hang in there and find the correct type of engine for your car.

checked the motorblock gasket?
if there is a little bit of water coming out of your exhaustpipe, that is the problem

what colour is the smoke. white or blue
