Vehicle: Mercedes-Benz CLA 200 Sport D

Year: 2016

Engine: 2.1L Diesel

Service: Stage 1 ECU Remap

The Customer’s Complaint

The owner of this CLA 200 Sport D came to us looking for more real-world performance, not headline figures like many modern diesel Mercedes models, the car felt:

Sluggish in the mid-range
Hesitant when overtaking
Overly conservative in factory throttle and torque delivery

The car was mechanically sound, serviced correctly, and fault-free — making it a perfect candidate for a safe Stage 1 remap.

Our Assessment

Before any tuning work, we carried out a full pre-tune health check, including:

Diagnostic scan (no fault codes present)
Live data review
Boost, torque and limiter analysis
ECU software version verification

This engine is well known for being heavily restricted from factory, primarily to suit emissions targets rather than drivability. No hardware modifications were required.

The Stage 1 Remap

This was a custom Stage 1 calibration, written specifically for this vehicle — not a generic file.

We focused on:

Optimising torque delivery through the mid-range
Improving throttle response
Maintaining safe exhaust gas temperatures
Preserving DPF and emissions system integrity

Results

Factory vs Tuned Figures

Power: 136hp ➜ 170hp (+34hp)
Torque: 300Nm ➜ 380Nm (+80Nm)

The difference on the road is immediate.

Driving Impressions

After the remap, the CLA now delivers:

✔️ Strong, smooth mid-range pull

✔️ Easier overtaking with less throttle input

✔️ Improved drivability in everyday traffic

✔️ More relaxed motorway cruising

Importantly, this isn’t about chasing maximum numbers — it’s about usable performance where you actually drive.

Many customers also report improved fuel economy when driving normally, thanks to the extra torque reducing the need to rev the engine.

Reliability & Safety

Every remap we carry out stays well within the safe limits of the engine and drivetrain.

No aggressive boost spikes
No unnecessary limiter removal
No stress on the turbo, clutch, or gearbox

This car remains fully road-friendly and daily-drivable.

The Takeaway

The Mercedes-Benz CLA 200 Sport D is a great example of how much potential is hidden by factory software.

A proper Stage 1 remap transforms the car from feeling restrained to feeling confident, responsive, and far more enjoyable — without compromising reliability.
