Doug phillips Posted July 7, 2016 Share Posted July 7, 2016 I cannot offer you any help, but just to say that my year 2000 1.8 VVC has never had to have one. I even had to change the place I normal use this year, and it was not even mentioned Link to comment Share on other sites More sharing options...

john milner Posted July 7, 2016 Share Posted July 7, 2016 What did it fail on? For example lambda is probably an air leak so is unlikely to be fixed by a new cat. Link to comment Share on other sites More sharing options...
Dorset7 Posted July 7, 2016 Share Posted July 7, 2016 I just had this on my MOT this week. Failed due to a leak on the end cap - taped it up and retested and it went through just fine.The location of the Lambda sensor doesn't help, they struggle to get really hot enough on the cat pipe.

Titanium7 Posted July 7, 2016 Share Posted July 7, 2016 Nothing wrong with the car it's something wrong with the MOT centre not being friendly enough Someone should be along with some help shortly ........... Link to comment Share on other sites More sharing options...
