VW Eos Diesel Stalls: Fuel Pressure Issues Explained

Having experienced similar symptoms on my Golf TDI, I can relate to those fuel system troubles. The rough running, jerking during acceleration, and stalling pointed to a faulty fuel pressure sensor in my case. The engine misfire and poor idle were classic signs of fuel delivery issues. The main problem turned out to be corroded wiring connections at the fuel pressure sensor plug. When the connection is compromised, the engine control unit receives incorrect readings, causing the fuel pump to deliver inconsistent pressure. This creates the erratic performance you described. The repair involved: Testing the fuel system pressure, Cleaning connector terminals, Replacing the wiring harness section, Reprogramming the fuel system parameters It was a serious issue that needed immediate attention since bad fuel pressure readings can lead to engine damage over time. After the fix, the fuel economy improved significantly and all drivability issues disappeared. Consider getting a second opinion from another shop that specializes in VW diesel engines. The symptoms align closely with fuel pressure sensor problems, which is a known weak point in these engines around the 130000-150000km mark.

Thanks for sharing those details about the fuel system repair. You mentioned corroded wiring as the root cause, definitely good to know since my Eos shows similar engine misfire symptoms. The stalling issues are really concerning me. Did you track any other problems after getting it fixed? Also curious about the total repair cost since fuel system work can get expensive. My local shop quoted quite high but I want to compare prices before deciding.

Thanks for asking about the follow-up. Since getting the fuel pressure sensor issue resolved, my car has been running perfectly with no engine misfire or stalling problems. The repair actually turned out simpler than expected, it was indeed just a faulty cable connection that needed fixing. Total cost came to 95€ for the wiring repair work. The fuel delivery is now consistent and smooth, with none of the previous jerky acceleration or rough idle issues. I track fuel consumption regularly and noticed it has improved quite a bit since the repair. No other fuel system problems have surfaced in the months since. If your symptoms match what I experienced, you might want to specifically ask them to check the sensor connections before replacing any major components. Sometimes these fuel delivery issues have simple fixes rather than requiring expensive parts replacement.

I finally took my Eos to a different mechanic who actually listened to my concerns about the fuel system problems. They diagnosed it properly, turns out the fuel pressure sensor wiring was damaged, just like you mentioned. The rough idle and stalling were definitely from inconsistent fuel delivery. The repair cost was reasonable at 120€, much less than the 500€ quote from the first shop. They cleaned the connections, replaced a section of wiring, and recalibrated the system. The engine runs smooth now with no jerking during acceleration. Fuel economy is back to normal too. Really glad I got that second opinion instead of paying for unnecessary repairs. The car has been running great for the past two weeks with no signs of the previous issues. Thanks for helping me understand what to look for, saved me both time and money.
