Error code and catalytic converter

YorksMG2013 · 16th June 2014, 18:22

Dear All

I had a 'check engine' dashboard warning end of last week, so car went to my local garage. The computer diagnostic has come back with - "P0420 cat malfunction."

Garage managed to clear the error code, but I imagine it may well come back.
In the experience of other owners, is this likely to be the cat or the sensor?

Emissions are a little over what is expected.

I had heard somewhere that the cats on sale from XPart are not as good as original MGR parts. Can anyone comment and/or suggest best source of replacement cats?

Thanks

Andrew

You can get a obd scanner that plugs in to the socket under the dash for around £ 20 then down load the free torque app to your phone. This is all you need to scan, identify and clear fault codes. But best of all you can use it as an accurate real time temp gauge...
