I have a bmw 316i compact and my key will not turn the ignition no more any answers

Get the code from the OBDII. Without it there are about 1000 answers.

Not familiar with the 316i but have had 97 M3 which exhibited similar trait. If the car is manual transmission try to gently pull the steering wheel to each direction while trying the key. If the vehicle is an automatic make sure the shift lever is all the way into the park position. In both cases it could be the safety interlock is causing the problem.
Depending on the mileage of the car - and for a 98 at an average yearly rate of 12K per year - I'm guessing the miles are up there, the ignition switch iteself could need replacing. If you have a good shop manual (Bentley) and posses mechanical abilities it is not too difficult.

These can be bought at most discount parts huses, e.g. Autozone, Advanced Auto, O'Reilly's, and Pep Boys for about $20.00. Haynes Service Manual:

Should be a 318i, what is the year? Have you checked relays, and depending on the year, these cars have ews modules that is a bit tricky to bypass. Unless your experienced at this on BMWs do not bypass ignition system. Hook the system back up using the factory key and try again.

i am driving a bmw316i 1997model on my dashboord showing this (!)when i am driving could u tell me what does it mean

The ignition is controlled by the motronic control unit its mounted on the passenger side of the dash above the glove compartment.

on the edge of the ignition barrel there is a little hole, you must turn the ignition to the first click and insert i 1.2 mm rod (drill bit)about an inch down into the lock and puch back the ident then pull the key and barrel out together.

it may be possible that your heater core was faulty and some has by passed it. open hood and check for incoming and outgoing heater hoses into firewall(dash of car). it is also possible that the heater core is plugged, try getting your cooling system flushed

hook up the fan striaght see if it helps

hi markjones, the ignition switch can usually be removed without too much disassembly. First you will need to remove a plastic screw in the upper and lower trim covers. Seperate the covers. You should see a black plastic ring around the mechanical switch. gentley remove the ring. Next remove the rubber o-ring/band. With the key in the iginition and turned to almost to position 1, insert a heavy duty paper clip, or bmw special tool (about $30 from the dealer) into the small hole in the switch. There is a cam in the hole that needs to be twisted clockwise so the cylinder can be removed. When installing a new switch make sure to remove the little tab pice of metal that usually breaks off in the housing. Also be sure to make sure and reinstall the rubber ring/band because they are part of the ews system. If you key turns continuously, or is not able to be removed, the ignition housing and cylinder both will need replaced. Replacing the lock housing is about a 2 hour sequence and can be challenging. I would recommend a shop for that kind of repair.
