Leaking Intake Hose = Bad emission values?

[Donker]

My intake hose (MAF - Turbo) is in pretty bad shape. Is it possible that this causes bad emission values? I have changed the lambda sensor, and the old one was all white.

Is the hose the problem, or is it my cat (only have one stock cat fitted on my car) that is bad?

Trying to get the car through the Swedish version of MOT tomorrow. I guess all I can do is keep my fingers crossed.

I would say yes

You say its in pretty bad shape so i would imagine it has a hole in it ??

If so it will be sucking in air after the MAF so its not metered so i would guess it would'nt be running right

There are no obvious holes in it, but it has marks and it's ruptured by the turbo connection. After changing the lambda, the car runs much better though, with the exception of running in limp-home mode with 0,4 bar boost.

Just to let you know, it passed the emissions test. Just a couple of bulbs, and the rear droplinks to replace and I can drive it!

Good news!
