VW Bora Flashing CEL Points to EVAP System Failure

Had exactly this issue with a 2005 VW Golf 1.6L. The check engine light started flashing and the engine would stall at idle, classic symptoms of a tank ventilation system fault. The EVAP system had multiple clogged hoses and a failing purge valve. The emissions system diagnostic revealed carbon deposits blocking the ventilation lines between the fuel tank and engine. This creates pressure issues that affect engine performance. The full repair involved: Cleaning all EVAP system hoses, Replacing the purge valve, Checking fuel tank pressure sensor, Clearing fault codes It was a serious issue that needed immediate attention since it affects both emissions control and engine performance. Delayed repairs could lead to complete engine stalling and potential catalytic converter damage. The fix restored proper idle, eliminated the check engine light, and resolved the stalling. For a 2002 Bora, these symptoms strongly point to similar EVAP system problems. Would recommend finding a shop that specializes in VW fuel system repairs.

Thanks for sharing your experience. I had the same purge valve and EVAP system problems with my Bora last summer. Really glad to hear your automotive repair shop managed to fix it properly. Getting those fuel tank pressure issues resolved made such a difference to how the car runs. How much did the complete repair end up costing you? Just wondering if prices have changed since I had mine done. Also, has everything stayed working properly or have you noticed any other issues come up with the tank ventilation system since the fix?

Got good news to share since my last reply. The automotive repair was completely successful, no more engine light or ventilation issues since fixing those clogged hoses in the EVAP system. Total cost came to 175€, which covered both parts and labor. The purge valve replacement and thorough system cleaning really solved the problem. The tank ventilation is working perfectly now, no stalling, no warning lights, and the engine runs smoothly at idle. After six months, I havent noticed any related issues coming back. The shop did a thorough job checking all components of the EVAP system to prevent future problems. If your check engine light starts acting up again, having the ventilation lines inspected early can prevent bigger issues. Regular maintenance of the EVAP system components is key to avoiding those frustrating tank pressure problems we both experienced.

I finally decided to get my Bora fixed after getting this helpful advice. Found a certified VW specialist who really knew what they were doing with fuel tank ventilation systems. They diagnosed the exact same EVAP system issues, clogged lines and a bad purge valve. The repair cost came to 190€, slightly more than expected but worth every cent. The mechanic showed me all the carbon buildup they cleaned out of the system. My check engine light is now completely gone and the car runs perfectly at idle. Such a relief to have this fixed properly. The automotive repair shop did a complete pressure test afterward to confirm everything was working correctly. Really appreciate the advice here that helped me understand the problem before going in. Saved me from getting overcharged or having unnecessary work done.
