Low N' Slow Posted October 18, 2017 Report Share Posted October 18, 2017 Hi guys, I have a 1ltr Arosa. I squished my cat on a speed bump ages ago, I've not been able to afford a new cat so I put a straight pipe in it's place. I therefore had the 02 sensor cut out for the time being. As my car has an engine management light because of it, I was hoping having that deleted would help it through MoT (lol). It just wont go through emissions by literally 1 or 2 numbers! Anyone have any ideas how to sort or if anyone has had a straight pipe in place with no issues? I'm thinking I may have to replace it with a new cat with the 02 sensor back in it, and maybe remove centre box and have the straight pipe there (for noise, otherwise I over rev then hear the car LOL) But this is obviously a more costly way. I wanted a sports cat but couldn't find one for it! Had sports cats before with no issues. It's currently waiting to go back in for re-test soon as I can think of the cheapest way for me (unfortunately). Thanks Quote Link to comment Share on other sites More sharing options...
Sausage Posted October 18, 2017 Report Share Posted October 18, 2017 Couldnt you fool the ecu just with resistors on the lambda? Dont know, only dealt with diesels for years now tbh. Quote Link to comment Share on other sites More sharing options...

Pete Posted October 19, 2017 Report Share Posted October 19, 2017 As above, mine failed once so the tester hooked up his bosses brand new jag. Still failed...? 1 Quote Link to comment Share on other sites More sharing options...

Rich Posted October 19, 2017 Report Share Posted October 19, 2017 you have to weld one in or find an independent friendly tester. Quote Link to comment Share on other sites More sharing options...

Low N' Slow Posted October 20, 2017 Author Report Share Posted October 20, 2017 Thank you for your replies everyone ?I will see what I can do! The fact it's only just failing by a smidge is a pain lol. No other holes in my exhaust system either ? Quote Link to comment Share on other sites More sharing options...
Rich Posted October 21, 2017 Report Share Posted October 21, 2017 chuck a rag over the end! I've seen some magic rags on emissions testers. Quote Link to comment Share on other sites More sharing options...
JoeyEunos Posted October 21, 2017 Report Share Posted October 21, 2017 @Rich We clearly use the same MOT tester. I too have seen the 'magic rag' on more than one occasion Quote Link to comment Share on other sites More sharing options...
Rich Posted October 21, 2017 Report Share Posted October 21, 2017 you travel for yours? i wouldn't use anywhere else. Quote Link to comment Share on other sites More sharing options...
JoeyEunos Posted October 21, 2017 Report Share Posted October 21, 2017 Certainly do. I share similar sentiments. Quote Link to comment Share on other sites More sharing options...
Rich Posted October 21, 2017 Report Share Posted October 21, 2017 you know of the tip jar ? Quote Link to comment Share on other sites More sharing options...
JoeyEunos Posted October 21, 2017 Report Share Posted October 21, 2017 I'm conscious of the tip jar and always round up to £40 (£5 tip). Pretty much the done thing isn't it? Quote Link to comment Share on other sites More sharing options...
Rich Posted October 21, 2017 Report Share Posted October 21, 2017 £40 is standard. Jinner likes to holiday in the Algarve. Quote Link to comment Share on other sites More sharing options...

Doesn't surprise me in the least, he has the air of a cosmopolitan well traveled type. Ever used the workshop round the corner? I get them to fit tyres when needed, very affordable (£6 a corner). The other chap who works in there's a real character too. Quote Link to comment Share on other sites More sharing options...

I've been told it's due to the 02 sensor. So adding it back in to the straight pipe still may not work... and also been advised a rag won't work in my situ (due to the fact it's the main 02 sensor being absent, not the one by manifold). I may bite the bullet and replace with a new cat - and have the straight pipe replace the centre box instead. I'm used to louder cars, the Arosa has a very quiet engine so I stall as can't hear the revs ?? I usually claim it's because I'm a woman driver though, I can use that to my advantage sometimes lol ?

Rich Posted October 23, 2017 Report Share Posted October 23, 2017 All of a sudden I'm more interested. age? Stats? More details in general. back to the car, yes you should probably just buy a cat and a lambda, sling it back in and delete the backbox for the same noise.

Low N' Slow Posted October 25, 2017 Author Report Share Posted October 25, 2017 Hahaha! In my 20s...nearing the end of them anyway ? Yes I've decided to do just that Rich! I thought maybe chuck the straight pipe in place of the centre box. Would that make enough noise too? I am tempted to replace the back box. Though only had a new one 6 months ago ?

Low N' Slow Posted October 25, 2017 Author Report Share Posted October 25, 2017 After 2 years of ownership I should really know my car better.. but this is my little cheap runner whilst saving to work on another car ? Quote Link to comment Share on other sites More sharing options...
