I have a GB270 Sport wagon and I took it in for an MOT today, well, it failed and I was given the results.



From what I read online people say the lambada is the cause of this problem but according to this sheet it passed. I'm not sure if the actual value numbers are too high or not. I don't fully understand this information tbh lol.

Is this just a simple Catalytic converter problem? Or is there something else that could cause this? I've read that the engine map could have slipped a bit but I am also not an expert on cars so hopefully someone here could help a brother out.

Lastly, does anyone know a good shop for Subarus around the Cambridge area to fix the problem and do a general tune up?

 

It is a fail the sheet shows you the min and max allowed and if you look at your CO content they are both outside the parameters on your fast idle tests.

 

Hi Mate.
I believe Zen Performance are out your way and have a pretty good rep.
Failing that you could contact Tim Farmer who is mobile and again has a very good rep.
You'll find both on FB.

 

Nice, I called Tim Farmer this morning and sent him this sheet. He says it could be as simple as a small leak. Thanks a lot for the information! I really appreciate it!

 

I understand that, I was just trying to see if anyone had any clue as to what specific components cause something like that. I appreciate the reply though.

 

But you said "From what I read online people say the lambada is the cause of this problem but according to this sheet it passed."
There are a number of things you can do and replace to help with emissions.

 

Happy to help bud. Hope you get it sorted out.

 

Yeah, hope you get it sorted OK.... let us know how you get on! 👍
