ENGINE FAMILY

About the Mercedes-Benz OM651 2.1 CDI (200 / 220 / 250 CDI, 2008–2018)

The OM651 is the 2.1-litre four-cylinder diesel of the post-2008 C, E, GLK, GLC, ML, Vito and Sprinter, offered from 136 to 204 hp. Most versions are twin-turbocharged and the hardware is largely shared across outputs.

How a Stage 1 remap works on the Mercedes-Benz CLS C218 250 CDI 204hp

Stage 1 recalibrates injection, rail pressure, boost and the torque limiter. The gain is especially clear on the 200 and 220 CDI outputs. A full low-rev torque curve results, matched to the 7G-Tronic or 9G-Tronic gearbox.

Pre-remap checklist

Injectors and injector seals (Delphi injector issue on early production).
Timing chain noise and tensioner condition.
DPF load and, where fitted, the AdBlue system.
EGR valve and swirl flap mechanism.

This section is based on Prime Chiptuning workshop experience; the power and torque figures come from the catalogue measurement above.

Frequently asked questions

How much bhp does Mercedes-Benz CLS C218 250 CDI 204hp chip tuning add?

Catalog reference: power 204 → 240 bhp, difference +36 bhp (18%); torque 500 → 550 Nm. Actual results depend on vehicle condition and measurement.

Will chip tuning damage the engine?

No. Values stay inside the safety margin the manufacturer leaves; engine, gearbox and turbo limits are not exceeded. Every file is verified with a road test and data logging. If the car needs maintenance first (worn injectors, blocked filter, weak clutch) we tell you before starting.

Will my fuel consumption go up?

With the same driving style it usually drops, because you hold the same speed at lower revs and less throttle. If you use the extra power, consumption naturally rises. It is down to your right foot.

How long does it take? Do I leave the car?

Most cars take 1–2 hours and you get the car back the same day; no need to leave it. Some models need the ECU removed, which takes longer — we tell you when booking.

Can I go back to stock later?

Yes. The original file is read and archived before any work. We restore the factory software free of charge whenever you ask.

Does it void my warranty?

Changing engine software can affect the manufacturer warranty. If a dealer finds a fault to be software related, they may refuse that claim. We want you to decide knowing this. Your original file stays with us and can be restored before a dealer visit.

Will it pass the roadworthiness test?

Stage 1 power software does not touch emission hardware. Work on emission systems is offered only for uses permitted by law; road use and inspection compliance remain the owner's responsibility.

How much does Mercedes-Benz CLS C218 250 CDI 204hp chip tuning cost?

Price depends on the vehicle, the ECU and the solution chosen. Send us your vehicle details on WhatsApp and we will quote straight away. Inspection and measurement are free.

How is the work done?

We scan for faults and read the original software first. The file is adapted to your car's hardware, written, and verified on a road test. The original is archived.

Is DPF Delete possible on the Mercedes-Benz CLS C218 250 CDI 204hp?

Yes. Our library contains a verified DPF Delete solution for the Mercedes-Benz CLS C218 250 CDI 204hp. Once your original file is read, compatibility is checked and the job is applied.

What is checked on the Mercedes-Benz CLS C218 250 CDI 204hp before remapping?

Before working on the Mercedes-Benz OM651 2.1 CDI (200 / 220 / 250 CDI, 2008–2018) we check: Injectors and injector seals (Delphi injector issue on early production). Timing chain noise and tensioner condition. DPF load and, where fitted, the AdBlue system. EGR valve and swirl flap mechanism. If something needs attention, maintenance comes first; the remap is applied to a healthy engine.

⚠ Software work on emission systems is offered only for uses permitted by applicable law (motorsport, off-road use, export, fault diagnosis, etc.). Road use and inspection compliance of the vehicle remain the owner's responsibility.
