How to Reset Your W210 ECU
Do you know that you can breathe life into your W210s again, for free? Try this out on your car now to give it a shot.
- Turn the ignition key to the “ON” (not start) position
- Press the gas pedal to the floor and hold for five seconds
- Turn the ignition key to the “OFF” position (do not remove the key), then release the gas pedal
- Wait for at least two minutes for your ECU (Electronic Control Unit) to reset
After you have performed the above, start your car and drive around for a bit. You will notice any or all of the following:
- Less effort need to get your car on the move (extra power)
- Smoother upshift and downshift
- Better fuel consumption
How is that possible? The above procedure resets or erases the ECU’s memory on the adaptive transmission and throttle settings. When you drive over a period of time, your car remembers your driving style and adapts to it. When you perform the reset procedures, that’s akin to breathing new life to it.
Have a go and let me know if this works for you.

I just changed my W210 faulty cluster (fuel level stuck at max regardless of the amount in the fuel tank) to a new one, all meters work fine, however the Cummulative mileage is blinking and does not record any mileage, please advise how to solve the problem.

Hmm, I wonder if this works on an E300D (1999/W210)?
