1999 Mercedes-Benz E320 4MATIC Q&A
1999 Mercedes-Benz E320 4MATIC Question: Car shut off while driving after problem with keys & ignition hard to turn over.
1. My 1st key stopped starting the car one day. 2. The 2nd key worked for a while. Then it kept getting harder & harder for the ignition to turn over taking 1 to 3 tries each time b4 starting but car would run smoothly. Then car just cut off while I was driving & won't start. I replaced key batteries, car still won't start. Keys do turn in ignition. All lights work. Battery fully charged. Can anyone give me some suggestions of here to start? - carcarecyber
A bad key will give a no start not a cut off.These cars are known for bad crank sensors.If its just a no start and a second key works its most likely a EIS module.You will need a xentry scan tool and a work shop key from Benz. - ambler
