fonzooorooo 10 Posted April 24, 2013 Our recently purchased 1994 2L 8V has been de-catted. As I understand things, last year that was an MOT advisory, and this year it'll be a fail. ... So I'll be in the market for a new cat. My Dad (an avid reader of Honest John's column in the Telegraaarrfff) has flagged up that a lot of cheap aftermarket cats are exhibiting VERY poor life expectancy (barely a year in some cases!) So... What have you got fitted? How long has it lasted? Who supplied? I obviously don't want to fork out for a cheapie cat that'll die before it's next MOT, and can't help but anticipate big bucks for a dealer item!

Stonejag 10 Posted April 24, 2013 Find a friendlier MOT garage? Mine digs Stevie Wonder up every year to look at my exhaust... :lol: Quote Share this post Link to post Share on other sites
fonzooorooo 10 Posted April 25, 2013 Wullie: Nice! I have considered just leaving it, seeing what my MOT guy says, (plead ignorance if he flags it up!) and if i need one, it looks like there're a couple on ebay with 2 year warranties... I use the same MOT place every time, for all the cars, he's (relatively) cheap, and seems totally fair... It's one of those things where I WANT an honest test - I want everything "right" and as a DIY spanner-er, it's easy to miss stuff that he'll spot easily on the ramp!

fonzooorooo 10 Posted June 22, 2013 So, I got hold of a 2nd hand (original) cat off a mate breaking a B3 passat. 'rado went for MOT yesterday - emissions of 1.6%. Dammit!!!! I'll whack it on the CO meter and see if I can get it down on the mixture (de-cat guy could've cranked the fuel up) Does anyone know the ideal CO% for these? (I know the MOT limit's 0.2%) ... Just handy to have a number to work to! At least the other 2 fail points weren't too bad - (1) wipers not clearing the screen (screen's warped - wipers are new - going to try old fashioned wipers and stronger springs in the wiper arm(!) and (2) Number plates too small - lettering and spacing correct, but 2 digit reg, so someone put shortened plates on.

davidwort 0 Posted June 23, 2013 I've a new cat on my 8v that was 45 quid! Trade price from ecp iirc, clearly smaller and cheaply made compared to a vw original but it's done two years mot with spot on emissions. Quote Share this post Link to post Share on other sites
fonzooorooo 10 Posted June 24, 2013 Sorted. As I hoped, whoever de-catted had adjusted the air flow sensor. Gave it a tweek back 3 notches to give a pre-cat CO of about 1% back for the re-test and got: CO limit: 0.2% 'rado: 0.02% HC: limit: 200 'rado: 16 Lambda needs to be between 0.97 and 1.03... 'rado is 1.022 So that's a pass. Job done! Cheers for the input! Quote Share this post Link to post Share on other sites
