Symptoms we can diagnose and repair are:

  • Turn The Key Nothing Happens no Dash Lights
  • Unable To Start The Vehicle
  • Turn The Key – But Vehicle Won’t Start
  • Intermittent Ignition Key Faults
  • Vehicle not responding to remote

If the EIS unit becomes faulty, the key will turn but no dash lights will illuminate and the engine will not start, also the steering lock will not release. This will stop the engine from starting.

It is very unfortunate but also a very common problem with the w447 vito electronic ignition switch. There are many reasons as to why these units fail. Some of the most common reasons are listed below:

  • Jump Starting Whilst Key Is Inserted
  • Power Surge
  • Low Battery Voltage
  • Damage to key
  • Damage to eis

All of the above can cause memory loss or corruption of the EIS module and it cannot be repaired or re-flashed using the usual Mercedes diagnostic systems.

At this point most mechanics will advise you to purchase a new ignition unit direct from Mercedes which can work out extremely expensive and will need programming and coding before it will work
