Check engine light on but engine is running sweet
Posted 12 January 2017 - 12:03 AM
Same story, light came on and has stayed on ever since, but the car is running sweet. I know that there is a raft of different possibilities as to what it could be, but what I'd like to know is if there is anyone else with the same vehicle that has had the same/similar problem? If so, do you have any advice or tips on solving the problem or what to look for first? Thanks in advance.

Have the code read. In the us many auto parts chains readncodes for free. You can get a cheap OBD11 scanner on eBay as well and do it yourself for.

In the US people routinely clear the code before those inspections. if you don't pass, you have to fix it and come back, no big deal. sometimes you can just go to work, clear the code again, drive back tomorrow and pass again.
P0420 code is the most common. Shops will quote rather large repair bills for catalytic converter.
Make sure you have no exhaust leaks, plugs, wires, air filter, PCV valve are up to date or not problematic (they usually aren't). Some people try seafoam treatments, etc before going with a catalytic converter replacement.

Need the CEL code/s to be sure where to go next.
I had a 0420 code caused by a very small exhaust leak.
