Check Engine Light Due to Catalytic Converter Fault on Volkswagen Passat

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.

my exhaust got very loud and I was told it's the catalytic converter and your system how much do you think that would run to get the repair done
Catalytic converter light came on after gassing up
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.
Engine jumps, EPC light flashes and light remains illuminated. Just got the car 4 months ago....
The worst car ever produced. Electrical problems and just now the catalytic converter. Stay away from this brand.
Engine light keeps coming on, car. Jumps when I break, this should be covered by Volkswagen, as is still new car, now they are trying to rip me of, I will never buy Volkswagen again, I should have listened to people! !
Covered under warranty...
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.
Check engine light came on. Vw dealership told me the cathartic converter needed to be replaced $2740!!! WTF!,
I couldn't pass the smog test due to the check engine light. I ordered a new catalytic converter from and paid a mechanic to install it. I passed the smog immediately after.
This started at 70,000 miles and the dealer did nothing to get the engine light off. At 80,500 the catalytic converter failed, car was stranded on the freeway! VW would do nothing about this. I purchased a 1,300.00 extended warranty for 5 yrs/100,000 miles. I was over 5 years and JUST over the 80,000 in warranty mark, however, I feel strongly that engine light should have been addressed prior to the 80,000 miles. It cost me 1,200.00 and my loyalty as a VW owner is gone forever!!
The light always comes on once Ive put gas in the car. I never want to get pass half due to this is when it happens. Also miles per full tank varies. Never sure how many miles I have per tank.
The check engine light goes on and off. Report shows it's the catalytic converter.
had re-flash. always comes back on eventually
I had to replace both at a very high cost
Check engine light on
Catalytic Converter not ready.
Check engine light on all the time indicating an issue with the catalytic converter. Will have the ECM reflashed at service.
