Check Engine Light illumination can be related to a catalytic converter fault. Our technicians tell us a re-flash of the ECM may correct the concern. If not, replacement of the catalytic converter may be required.

Volkswagen Passat Check Engine Light Due to Catalytic Converter Fault
Volkswagen Passat Problem
Exhaust & Emissions Affected: 2.0L 4 Cylinder Turbo
Average Mileage: 100,638 mi (35,000 mi - 175,000 mi)
My check engine light has been on for sometime now. I had the vehicle look at and they said from the codes I need a catalytic converter. I had a left catalytic converter repair and days later my engine light is on again. I took my car back to the shop you replace the left converter and the guy said I may still have a leak somewhere in my exhaute system. I feel that if this was the problem why wasn't this mention when I first came to the shop three days prior. I'm starting to feel like these repair people are just trying to make money off me me but without really fixing the problem.
Check engine light on all the time indicating an issue with the catalytic converter. Will have the ECM reflashed at service.

I had my exhaust manifold blow of the connection to the pipe - you could see it from the top of looking into engine compartment. LUCKILY - i had a friend who tack-welded the piece back together.
That was over a year ago & i am now having the check engine light re-appear. but i have a code reader - so i just clear the code.
