Mercedes Benz EIS / EZS Repair and EIS testing 

 

The Mercedes Benz DAS system mainly works around the EIS Electronic Ignition Switch so any malfunction or  a fault may cause the system to not work as intended

 

The Electronic ignition Switch holds vital Key data and links to the ECU and ESL Electronic Steering Lock and also acts as a central gateway to other vehicle electrics, Meaning Electronic Steering Lock and key faults could seem to cause other problems in the system.

 

Some symptoms of a malfunctioning EIS Electronic Ignition Switch include

Not allowing the key to turn in the ignition switch
Not releasing the ESL Electronic Steering Lock when the key is Inserted
Intermittent failure of internal components causing intermittent faults
Complete failure of internal components
DATA corruption
Dirt ingress
Incorrect programming by an incompetent garage/mechanic
 

Many Electronic Steering Switch's can be easily fixed, with replacement parts or a service exchange unit - If a unit cannot be repaired or replaced we can supply a new unit which is fully plug and play requiring no other programming.
