About the Mercedes-Benz OM654 2.0 diesel (post-2016 180d / 200d / 220d / 300d)

The OM654 is Mercedes' aluminium-block diesel introduced with the E-Class in 2016 and used in the C, E, GLC, CLS, Vito and Sprinter from 150 to 265 hp. It is equipped with AdBlue and a DPF.

How a Stage 1 remap works on the Mercedes-Benz C W205 300d 245hp

Stage 1 recalibrates rail pressure, injection, boost and the torque limiter. Together with the 9G-Tronic gearbox, a full torque delivery from low revs results; overtaking and long-distance comfort improve clearly. Emissions systems are preserved.

Pre-remap checklist

AdBlue system and NOx sensor health.
DPF load.
Oil service and the correct oil specification.
Gearbox oil service.

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 C W205 300d 245hp chip tuning add?

Catalog reference: power 245 → 270 bhp, difference +25 bhp (10%); torque 500 → 560 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 C W205 300d 245hp 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.

What is checked on the Mercedes-Benz C W205 300d 245hp before remapping?

Before working on the Mercedes-Benz OM654 2.0 diesel (post-2016 180d / 200d / 220d / 300d) we check: AdBlue system and NOx sensor health. DPF load. Oil service and the correct oil specification. Gearbox oil service. 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.
