Skoda Yeti Diesel Stalling Issue Resolved

My 2015 Skoda Yeti diesel stalls at idle, engine power is down, and the check engine light is on. Diagnostics say it's a bad fuel pressure regulator. It started right after changing the fuel filter. I think there's a pressure drop in the fuel rail. Any ideas?

That sounds frustrating. I had something similar with my Fiat Punto diesel. Check engine light, rough idle. It was a faulty fuel pressure sensor. See if your Skoda's fuel pump is giving consistent pressure to the fuel rail. Is there a pressure drop when the engine stumbles? When did you change the fuel filter, and was it the right one?

You mentioned a fuel pressure sensor. Is that the same as the fuel pressure regulator, or are they different? The fuel filter was changed right before this started. Could a bad install or a faulty filter be the problem?

My bad, I was too quick. It was the fuel pressure regulator on the fuel rail, not just the sensor. And yes, a badly installed or wrong fuel filter could cause fuel pressure problems. Check the filter housing for leaks or damage and make sure the filter is right for your Yeti. If unsure, take it to a workshop.

Replacing the fuel pressure regulator fixed it. The error is gone and fuel efficiency is back. The cost was about 45€. Thanks for the help.
