Skoda Superb engine trouble

I'm at my wit's end! My 2013 Skoda Superb with a gasoline engine is giving me grief. The check engine light is on, and the engine performance is terrible. I've got reduced engine power, the engine response is sluggish, and my fuel consumption has gone up. A friend suggested it might be the manifold pressure sensor, possibly caused by a large vacuum leakage. Anyone else had this issue?

Sounds like a classic case of a failing manifold pressure sensor, especially with those symptoms on your 2013 Skoda Superb. The sensor, sometimes called a MAP sensor, measures the pressure inside the intake manifold. That data helps the ECU (engine control unit) determine the correct air/fuel mixture. When it goes bad, the ECU gets incorrect data, leading to all sorts of engine performance issues. A large vacuum leak would definitely cause the readings to be off. Have you checked for any obvious cracks or loose hoses around the intake manifold?

Thanks for the quick reply! I'm not really a mechanic, so I'm not sure how to check for vacuum leaks. What exactly should I be looking for, and where on the intake manifold?

Okay, given your limited experience, probably best not to mess with it yourself. A vacuum leak isn't always easy to spot without the right tools and knowledge. It's very likely a faulty manifold pressure sensor because that would explain all your symptoms perfectly. Sensor replacement is usually straightforward. I'd recommend taking it to a trusted mechanic for diagnosis and sensor replacement. It will save you a lot of headache in the long run.

Big thanks for the help! Took it to a local garage and they confirmed it was a faulty manifold pressure sensor. They replaced it, and the engine performance is back to normal. Cost me about 235€, all in. Glad it's sorted!
