Mercedes Turbo Actuator RepairsMercedes CLS Electronic Turbo Actuator Problems
Are you experiencing a loss of power in your Mercedes CLS? Have you been told you need a new turbocharger and have a repair bill in excess of £1500? One of the most common failures on the Mercedes CLS from 2004 – 2010 is the Electronic Turbo Actuator. The electronic turbo actuator (wastegate) is controlled by the engine ECU and has a rod connecting to the turbo vanes which is designed to regulate the flow of boost pressure from the turbocharger.

Below we’ve put together a shortlist of part numbers for the electronic turbo actuator:

Common Part NumbersCommon Part Numbers

When the electronic turbo actuator becomes faulty, you may experience loss of power, warning lights appearing on your dash, juddering on acceleration or a combination of faults depending on how the actuator has failed and whether the turbo vanes were open or closed when the actuator failed. Some of the most common symptoms we’ve seen from a failed turbo actuator on the Mercedes CLS include:

  • Loss of power under acceleration
  • Intermittent loss of power under acceleration
  • Smoking on acceleration
  • Fault codes pointing to turbo actuator
  • Fault Code: 2510 – Boost Pressure Control
  • Actuator arm not moving
  • Engine light on
  • Limp mode

Mercedes Turbo Actuator FaultsIf your local dealer has diagnosed a faulty turbo actuator, you will be quoted for a complete new turbo + actuator unit costing over £1500 to replace because the actuator itself is not a part that can be purchased separately. The alternative option would be to have Sinspeed remanufacture your actuator unit for much less and the remanufactured unit would be returned to you with a Lifetime warranty ready to fit.

Mercedes CLS Turbo Actuator Repairs – By Sinspeed
We have the facilities to fully bench test and rebuild the electronic turbo actuator and by using new genuine OEM components as well as uprating components that are known common weaknesses, we can ensure that each and every rebuilt turbo actuator meets & exceeds OE specifications. All of our repaired turbo actuators are retested before leaving the workshop and are returned to our customers with a Lifetime warranty. Your unit will be returned fully plug & play meaning no programming is required when refitting.

Professional diagnosis & fitting services available.

Sometimes the turbo failure can be due to carbon build up inside the turbocharger unit and in such cases, it is advised to have the turbocharger rebuilt at the same time to avoid damaging the newly rebuilt actuator unit. We can rebuild turbochargers with new seals, bearing and balancing at a fraction of the price of a new unit and all turbo rebuilds are covered by our 2-year warranty.

For more information on any of our services, please call us on 0203 815 9441.
