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.

The worst car ever produced. Electrical problems and just now the catalytic converter. Stay away from this brand.
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
Covered under warranty...
Engine jumps, EPC light flashes and light remains illuminated. Just got the car 4 months ago....
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.
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.
The malfunction light in on and the engine makes a loud noise
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! !
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!!
engine malfunction light on
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.
First the ignition coil and spark plugs failed. Very soon after that my check engine light comes on and I take it to a certified vw mechanic and he informed me that the catalytic converter is faulty and is making my emissions high.
Check engine light keep coming up for Cadillac converter And Air temp sensor and i changed the air temp sensor
light appears 2 weeks ago after sitting for 4 days. Now light re-appears and stays on. This is a CC not Passat.
