Fix your Mercedes Benz "Start Error"

Does your Mercedes Sprinter, Vito or other model show a ‘Start Error’ message on the dashboard? MercKeys have dealt with these issues on many Mercedes commercial vehicles.

The main cause of the START ERROR being displayed on the dash is due to corruption of data in two of the vehicles main units, one is the Temic Immobiliser box (also known as the WSP) and the main Engine Control Unit.

We recommend trying a few things prior to giving us a call.

  • Test the vehicles battery
  • Try a different key
  • Try your original key on its own with no other keys near the ignition

If you have done this and you still have the START ERROR message there could be a number of issues, we recommend having a diagnosis by our team to pinpoint where the fault lies.

We will get as much information over the phone as we can to give you a rough diagnosis then move forward with fixing the fault.

Common problems leading to START ERROR on a Mercedes include:

  • Jump starting
  • Battery running low
  • The transponder in your key is faulty or missing
  • Antenna coil on ignition faulty
  • ECU fault
  • Fuel pump fault

Some words from our customers

    I required a secondary key for a Mercedes Benz import I had just purchased, after researching for this service via trademe and MercKeys I came across Dale. Top man, expert knowledge and truly fantastic service. He was simply a breeze to deal with and was very quick and on point. He took all the stress out of the situation for me. Dale, thank you very much Sir!

    Dale from Merckeys is an absolute legend!! A MASTER technician and a stand up bloke!! Dale from Merckeys went above and beyond to accommodate for my situation. Dale worked fast and explained what he was doing step by step for my simple mind. I saved ALOT of money as I was going to get charged an arm and a leg then some from an aftermarket workshop. I give Dale 10 out of 10 rating and will most definitely be recommending Merckeys. Thanks Dale and Merckeys simply the best!!? From a Mercedes owner on a low budget much appreciated.

    Being a Merc owner with a W202 97 C class c230, my old key was beginning to die a slow death until it packed up 2 days ago, at a shopping center. Not able to get back into the car, i asked the Merc dealership down the road to assist, and they told me a new key would cost 3900 and 3 weeks to arrive. With no such time on my hands, I found Merc keys and had such great customer service and assistance from them. 2 hours later my car was up and running with a new key. Thanks again.
