My 15 year old has saved his money and purchased a 2002 C230K for his first car. We picked it up at the dealer and drove 4 hours home. I watched and the car was started at least 20 different times without any problems. We got to a gas station and it would not start. He removed the key and reinserted several times and then it started. Got the car home and now it won;t start again. There is only one key and I changed the batteries in it. Cleaned the IR lenses. NOTHING! The car relays are all clicking when the key is turned but it will not start. Any help for a new young lad trying to get into the Mercedes world would be greatly appreciated.

Does it crank but the engine doesn't fire up or does it not turn over at all? I doubt that I can help you, but that info might prove useful to the many experts on here.

It does not turn over at all. There is a click and that is it. Like there is no signal getting to the EIS or something. I've tried everything I know. There are no fault codes on display or on a scanner (OBD II). Everything works electricall with the remote as it is suppose to. Thanks for they reply

I think you can safely rule out the key. That was good thinking to have the codes read because that would have been the next question someone asks you.

Are you sure the electrical system (difficult to check it all but you could test the fuses, relays) and battery are both OK? Some of the key-acticated functions involve vacuum pumps and maybe there is enough juice to power those but not to start the car. If those are good, the next place I would look is at the ignition switch. After that, the starter motor.

If the key would not be authorised by DAS, it would not turn in the slot at all. Your EIS should then be fine.

On an IR key with no flip metal key (just one inserted in a slot), key authorisation works through IR but actually neither one needs the key battery to make the car start. So the battery in the key is not the issue.

Where to you hear the relay click sound? It it is at the starter motor itself, it would be an issue with the starter solenoid contacts or even more likely the brushes. Would be useful to measure the voltage at the starter motor solenoid input.

How much has the car been driven? It could be low battery after all like mentioned above. But if it failed starting just after some driving, then there needs to be an alternator/charging issue.

or get it on a charger overnight at 10 amps and give it a start.
6 year old battery most likely not holding a charge anymore.
Roadside will also jump start it and if it starts will diagnose the charging system and give a pretty fair deal on replacement.

follow charging procedure in the manual

I must be a moron! Of course, your car is disabled and you do not have to be the original owner to qualify for this. Call them and please report back, some of us on here might learn something. Thanks OhLord.

Its a batttery issue, had this problem a couple of days ago. The battery only had 10-12 volts, you need at least 14 to turn the engine over.
