Hi guys,
Just wondering if someone can confirm that I'm on the right track here.
Keep getting fault code 16804: catalyst system below threshold and the engine light comes on each time I clear the code.
Now, from the information I've gathered from a search, it's either........
a) Dodgy oxygen sensor.
I've replaced both of these recently. I did the post cat sensor at the back
end of last year and the pre cat sensor was replaced last night, so I'm ruling
these out.
b) Knackered cat.
What's the symptons of this? Is there any loss of perfomance when this
happens? The car still flies so I'm unsure if this is the problem.
c) Possible leak from joins on exhaust.
This is something I'm going to check and make sure all clamps are tight.
Would even a small leak be audible? Any other side effects from this?
d) Use a spacer on the post cat sensor.
Anyone know where to find one of these?
Is there anything else I may have missed that could be causing this?
Sorry for all the questions but this is something that's been going on for the last 2 years (yes 2 years) and cost me a small fortune in the process. Lots of stuff has been replaced like MAF sensor, oxygen sensors, coilpacks, sparkplugs etc etc (all done this year). All vaccuum piping has been replaced with silicon pipework and is leak free.
The car is a Jabba mapped Ibiza with K03S, 3"dp with 100cel cat bought from AM Motorsport.
