Mercedes-Benz ignition switch (often referred as immobilizer module) can become faulty and in some cases due to user error. For example, some common reasons why the ignition module failed are:

  • Low battery voltage
  • Power surge due
  • Connecting jump starting cables while key is in the ignition.

During any of the above scenarios, the EIS-EZS may lose its memory. While it can be diagnosed with Start Diagnostic Scanner used at dealerships, it can’t be repaired with this scanner. Mercedes dealers don’t repairer a bad EIS-EZS module. They will recommend that the module be replaced. That’s not necessarily the only solution, see alternatives below.


We will repair your issue and mail out the ignition switch within 48-72 hours of receiving your
1) Ignition switch,
2) Existing keys for the ignition switch.

    It is heavy
    Size: 58.3mm, Color: Black
    Item was as described and shipped promptly. It is heavy and works well with my portafilter. I haven't had it long enough to really evaluate how helpful it is.

    Great little temper
    Size: 53mm, Color: Silver
    Works great! Only problem is that it doesn’t have that feel of tamping. Wish I had more feedback. It just goes down very easily and doesn’t have that feeling of solid tamping. Now that doesn’t mean it’s not doing its job. Works fine but would like some manual feedback.

    Take the guess work out of the flow!
    Size: 58.3mm, Color: Black
    I got this because when my wife makes espresso, it's watery. When i make it, it's fine. We needed a controlled Tampering method so we both do the same job. This is heavy, and being able to use the whole hand instead of fingers, not much effort is needed. Since we purchased this, we were able to make consistent espresso shots for sure.
