Mercedes SLC diesel engine cylinder pressure issue

Engine acting up Cylinder pressure woes in my SLC I have a 2017 Mercedes SLC diesel with nearly 186000 km on the clock and the engine's throwing a fit I'm experiencing some serious cylinder pressure fluctuation Fuel consumption is through the roof power's down and that dreaded check engine light is mocking me Any ideas I did not hear engine knocking or see problems with spark plug or timing belt Also no idea on fuel injector and turbocharger status

Your predicament with the Mercedes SLC diesel is not unfamiliar I too possess an SLC and encountered similar tribulations that resonate with your depiction The confluence of elevated fuel consumption diminished engine power and the illumination of the check engine light intimate a potential anomaly within the engine's intricate architecture The cylinder pressure fluctuation could stem from several origins including but not limited to a compromised fuel injector a malfunctioning turbocharger or even issues pertaining to the engine timing belt Have you discerned any unusual auditory phenomena emanating from the engine such as engine knocking or perceived any irregularities in the vehicle's acceleration profile

That's useful information What did you mean by 'irregularities in the vehicle's acceleration profile' and what was the cause of your problem

By 'irregularities in the vehicle's acceleration profile' I am alluding to any deviations from the vehicle's customary responsiveness when you depress the accelerator pedal This could manifest as a hesitation a sluggishness or an uneven surge in power delivery In my case the root cause was not what I expected It was a consequential error another error triggered it It would be prudent to seek counsel from a qualified Mercedes-Benz technician They possess the requisite diagnostic acumen to pinpoint the genesis of the cylinder pressure fluctuation and prescribe an efficacious remedy

You were right a visit to the workshop confirmed your suspicion It was indeed a consequential error Another faulty sensor caused all these symptoms Got it sorted for free as it was a minor fix Thanks for the advice
