2002 Volkswagen GTI Q&A
2002 Volkswagen GTI Question: catalytic converter damaged by ignition coils?
The check engine light came on this week. I took it to autozone to find out why. The codes point to engine efficiency. Means either vacuum hoses or the CC. My mechanic thinks the cc is damaged from the 2 ignition coils that failed about 2 years ago. Is it possible that a failed coil can damage the CC? - keving
Yes, failed coils could damage the CC, since raw, unburned fuel gets into the converter. Zee - ZeeTech
always clear the code and drive to see if it reappears before replacing cat very expensive and coil failure on vw s can cause cat damage but dont just replace it clear first - 25yrtech
