black_widow87 Posted March 10, 2011 Share Posted March 10, 2011 Took my car for an emmissions test only to find out its kicking out double what it should. I had the second cat put back in and run for about 30miles thinking it would help, obviously not! What does this mean? Any suggestions on what i can do as iv got my MOT at end of the month. Cheers guys Link to comment Share on other sites More sharing options...

It is expensive, but you might find your fuel economy improves significantly if the O2 sensor is shot. In fact, it might pay for itself over a few thousand miles. How about trying to clean it?

Yes they're expensive, but with the price of fuel as it is, a new one will pay for itself in fuel saving quite quickly. Link to comment Share on other sites More sharing options...
Nic Posted March 10, 2011 Share Posted March 10, 2011 How much for a new O2 sensor dude? Is it a simple job or am i gonna have to fork out alot of ££££'s? Is yours NA or TT? They are easy to fit either way, if you have a J-spec TT there is just one oxygen sensor, if you have an NA there are 2 oxygen sensors. Link to comment Share on other sites More sharing options...

black_widow87 Posted March 10, 2011 Author Share Posted March 10, 2011 Its a TT/Single, where abouts is it located? Think i might try give it a clean first to see if it makes any difference, if emissions are still sky high am i right in saying its the CAT that is knackered?

pezzler Posted March 11, 2011 Share Posted March 11, 2011 I replaced my o2 sensor last week, £132 from Steve Manley at Inchape Toyota in Kidlington. It must just be me, but I found £130 inc VAT quite reasonable for a brand new genuine sensor - especially considering the car its for Would recommend replacing the o2 sensor, my car has been running so much sweeter since replacing it Link to comment Share on other sites More sharing options...
