Mercedes C220 CDI – AdBlue and Performance

Can a little Mercedes C220 CDI hide some extra power from you? Yes – it can and it does. It hides at least +50HP and +60Nm of torque.

Small diesel engines have traditionally been the staple of VW, but Mercedes has their own answer now. Their small, efficient and well-rounded 2200CC diesel unit can be found in the W205 C220 CDI (or C250 CDI as it’s known in Europe) – the same power plant is spread between a few different shapes.

When you get to drive one, you get a feeling that it’s nice. However there are no other words that come to mind. Just…nice. Not exciting, not quick. Just…nice. The sort of feeling you get from a plain rice cracker – it lacks a topping. Any topping!

Let’s take a look at the Mercedes C220 CDI we had in the workshop. This car got delivered as a non-runner after sitting for two years outside. The poor rice cracker grew some mould and became home for little spider family.

Why AdBlue Doesn’t Work…

One of the major issues with cars that are equipped with the AdBlue additive system? – The fluid is highly corrosive and dries out. Dried out AdBlue turns into strong crystallized mesh. In turn, this jams the AdBlue tank level sensor, and because the sensor is a non-serviceable item welded to the tank itself, the repair is usually north of $6,000+GST. As an option, we can switch it off and the car will not have it any longer.

Mercedes A45 Performance and CLA45 Tuning

A45 Performance Tuning

Merc’s Go-cart from Hell!

Mercedes A45 Performance to match the title? Need extra 40hp and 60nm for that.

With an amazing amount of hot hatches on the market here, one may get lost in all the choices. Mercedes was ignoring the hot hatch category until 2014, but once they entered the market, boy did they get it right.

Spacious, nimble, maneuverable and well… somewhat underwhelming. When we drove one many years ago the response was – “Is that all? Really?”

This German idea felt a bit unfinished. Looking at the hardware, everything was there. Decent engine, decent size turbo, only minor restrictions. Excitement? Not quite there. Yes, it had power, but only when up at the redline. Apart from that there was not a lot happening until 5000RPM.

The solution came after a year of development – an A45 and CLA45 tune that would improve the dreaded midrange.

Here are before and after Dyno graphs of Mercedes A45 Performance. Green is stock car, purple is tuned with a catless downpipe and BMC air filter.

Tuned A45 Cla45
CLA45 A45 Dyno Stock vs Tuned WHP (Wheel Horse Power)
A45 Stock vs Tuned Derived Torque LB/FT (torque at wheels)

From the graphs you can spot where the excitement comes from. The difference is 92Nm of torque at the wheels and closer to 110Nm at the engine.

Mercedes-Benz C63 AMG ECU Performance Tune

Let’s examine one conspiracy theory. It is a popular held belief that ‘special release’ models are faster and for that you need to fork out another $50k. Let’s call it a ‘marketing ploy’.

What is it going to take for your C63 to go from being stock to achieving the power produced by that of the 507 Special Edition? An ECU remap by EuroSurgeon is the answer! You didn’t buy a C63 to drive it to Pak’nSave and back – you got it to enjoy that chill-inducing V8 rumble and to genuinely love the driving experience. So why not add another 55HP and 53Nm to it?

Mercedes-Benz C200 CDI ECU Performance Tune

Keeping it simple, nimble and comfortable is a well balanced act found in each Mercedes-Benz Diesel. Most of the time, no one will actually pick up that you drive a diesel. Feel like somebody robbed you of a bit of excitement from driving it? The cure for that comes from fixing the accelerator response and adding around 64HP and 90Nm of torque to it.
