VW Taigo Stalling: Rail Pressure Sensor Alert

I experienced identical symptoms on my 2020 VW T-Cross 1.0 TSI. The engine stalling and poor performance matched exactly what you describe, including the check engine light. The rail pressure sensor diagnosis proved correct in my case. These sensors monitor fuel pressure and when they fail, the engine management system receives incorrect readings, leading to the stalling and performance issues you mention. The repair required replacing both the fuel pressure sensor and cleaning the fuel rail system to ensure no contamination was present. This was necessary work as a faulty sensor can mask other developing fuel system problems. While the sensor itself is a relatively simple part, the overall fuel pressure regulation is critical for engine operation. Running the engine with a defective sensor risks additional damage to fuel injectors and other components. The symptoms cleared completely after repair and the check engine light has not returned. Make sure your mechanic also checks the wiring to the sensor and fuel system cleanliness, as these can cause similar symptoms but require different repairs. This is generally considered a serious issue that needs prompt attention to prevent potential engine damage or complete failure while driving.

Thanks for sharing that detailed experience with the T-Cross. Had very similar engine stalling and fuel injection problems with my Taigo last year. Good to hear the fuel pressure sensor fix worked for you, matches my experience perfectly. Quick question, do you remember roughly what the total repair cost was? And has everything been running smoothly since the fix? No more check engine lights or engine performance issues? Would be helpful to know since I am tracking these sensor-related problems to see how common they are in our engine type. The fuel pressure problems seem to be popping up more frequently in forum discussions lately.

Since fixing the rail pressure sensor signal issue on my T-Cross, the car has run flawlessly with no engine performance problems or warning lights. The total repair came to 240€, which covered the new pressure sensor installation and fuel system cleaning. The fuel rail and all related components have worked perfectly for the past year. The engine responsiveness improved significantly after the repair, and the stalling issues disappeared completely. The accurate sensor signal readings have kept the fuel delivery system working as intended. You make a good observation about these problems appearing more frequently in discussions. While the pressure sensor replacement solved the issue in my case, proper diagnosis is crucial since similar symptoms can stem from other fuel system components. The investment in fixing the sensor was worthwhile considering the potential damage a faulty signal could cause to the engine and injection system.

Thanks for the input. I finally took my Taigo to the mechanic last week. The fuel pressure sensor diagnosis was spot on, they found the sensor was sending erratic signals to the engine control unit. The repair cost came to 280€ including parts and labor. They also performed a thorough fuel system cleaning which helped restore proper engine performance. The mechanic showed me the old sensor and explained how its malfunction was causing the engine stalling issues. Been driving for a week now and the difference is night and day. No more check engine light, the engine runs smoothly, and the stalling problem is completely gone. Really glad I got this fixed before it could cause any damage to the fuel injectors or other engine components. Will keep monitoring and update if any issues return, but so far the diesel engine is performing exactly as it should. Good to know others had similar experiences and successful repairs with pressure sensor replacements.
