Code P0420 Catalytic Converter Replacement
The orange engine malfunction light has been coming on for a some time now and I've been erasing it, but it started coming on more frequently, so I did some research and tried a few things to correct it. The temp of the exhaust at the inlet of the converter was twice as hot as the outlet, so the problem was there. The engine idle was also starting to hunt. In gear, with the A/C on and foot on the brakes, the engine was almost at the point of stalling.
I tried the Lacquer Thinners solution as seen on youtube, but that didn't work. So I tried the Oxygen Sensor Spacer also from youtube, but that brought up another code, P0139, which is the "Sensor Circuit Slow Response" even more frequently than the P0420 code, so I removed it. I bought 2 new Oxygen Sensors and installed them, but the P0420 code was still illuminating the orange engine light on the dash.
I called Hitech Exhaust at Darlinghurst and spoke to Lambros, and he booked my car in to have the Catalytic Converter replaced the next day. I dropped it off to him at 7am and once it cooled they started working on it. They replaced the original Converter with a Stainless Steel one, and their price was the best price I could get anywhere. Some places around my area were charging twice as much. It was a good experience from booking it in, right through to picking it up, and the workmanship is great. I highly recommend them. The P0420 code and the orange engine light have not come back since. Also, the engine idle rpm is now perfect again, so all in all it was a great result.

Re: Code P0420 Catalytic Converter Replacement
Hi Dave,
The first time the engine light came on was at 138,000 K's nearly 2 years ago, but that was infrequently. I'm now on 176,000 K's, and the light was coming on after an hour of driving. I was told that E10 fuel (very rarely do I use it) can cause this problem even if the engine is designed to run on this fuel. Here's hoping you have a lot of K's left in yours.
Edit.... 187,000 K's and the engine light hasn't come on.
Cheers

From memory it was around $750 and took a few hours to change.
Was that the factory cat converter near the engine or the Hitech one installed underneath the Xtrail in the new exhaust ?
