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
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 came on. Vw dealership told me the cathartic converter needed to be replaced $2740!!! WTF!,
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! !
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.
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.
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!!
Check Engine Light came on. Visit to VW Service Center claims that catalytic converter must be replaced at $3500. Car 3 years old with 87k miles. Not covered under my expensive extended warranty.
Burnt out motor and turbo...still has issue..I sold the car with this issues..didnt know it had this problem until the motor blew out and afrer I paid 2k plus in motor repair was told thos was thw problem..
engine fault on along with frequent EPC light. Power is reduced to a maximum 3000 rpm when the EPC light is.
also the TPM (Tire Pressure Monitor) light is on.
Car was driven to friends house with no issues or codes. Once done after fire xs house to head home our VW didn't start. i bought a cheap car reader and it bought up catylist, O2 sensor, misfire, and heater.
