Saxo Diesel Exhaust - Cat Removed

[paul_smith30]

Hello there,

 

I have a Saxo 98 Diesel which my mechanic states has had the Cat removed at some point and replaced with a non-Cat exhaust system (I believe the early diesels did not have the Cat on)

 

What effect on the MOT will this have? As long as the emissions are lower than the specified level would it matter if the Cat has been replaced at any point?

 

Thanks in advance.

The MOT examiner tests the emissions of the engine and the general condition of the exhaust system from a leakage point of view. If the result is within limits, he's satisfied. But to my knowledge, the 1.5D never had a cat fitted, only egr.

hi again,

sorry for my lack of knowledge...whats egr?

 

there are two exhaust systems for a 1.5D, the early ones apparently did not have a Cat, but from sometime in 1997 a Cat was fitted?

 

This tallys also with things like Euro Car parts where there is a non Cat system and a Cat system.

 

Is there anything I can do to ensure that there is the best chance of the car passing its emission test? Thanks again

EGR -- Exhaust Gas Recirculation. It's a solenoid device which opens to put some of the exhaust gases back through the engine.
