Skoda Rapid Diesel Engine Issue

I am writing to inquire about a potential issue with my 2016 Skoda Rapid, diesel engine. The check engine light illuminated recently. Furthermore, I have noticed reduced engine power and some smoke when accelerating. I suspect a crankcase ventilation valve malfunction, but I would appreciate any advice or insights.

Summary of the thread

A 2016 Skoda Rapid diesel engine exhibited issues such as an illuminated check engine light, reduced power, and smoke during acceleration. These symptoms suggested a potential malfunction of the crankcase ventilation valve, which can disrupt the air-fuel mixture and affect engine performance. It was advised to check for a rough idle and seek professional diagnosis. The issue was confirmed and resolved at a repair shop, restoring the car's performance.

I encountered a similar problem with my Skoda Rapid. The symptoms you describe are quite indicative of a faulty crankcase ventilation valve. When this valve malfunctions, it can disrupt the air-fuel mixture, leading to reduced performance and increased emissions. Does the idle seem rough as well?

Thank you for your insights. Regarding the idle, I have not paid close attention to it, but I will check. Is there anything specific I should be looking for?

A rough idle would manifest as the engine shaking or fluctuating RPMs when stationary. Given the smoke and power loss, a defective crankcase ventilation is the most likely cause. Due to the complexity of the system and potential for further damage, I would recommend taking your vehicle to a qualified repair shop for diagnosis and maintenance.

Thank you for sharing your experience. I took the car to a trusted workshop, and they confirmed the crankcase ventilation valve malfunction. The repair cost was approximately 360€. The car runs smoothly now.
