Hi Guys,
I did a quick search before and found that the B1 S2 is the post CAT sensor. As I have a sports CAT am I best off just blocking it off with a plug you can get then getting it mapped out eventually? (I'm getting codes 16524, 17521, 17522, 17526 which all relate to lambda)
Any advice is always welcome :)
-
Could get it mapped out. Or slap a lambda in it and. Cure the codes.
-
Just trying to weigh it up because from what I have read all it measures is if the CAT is working or not, as mine is a sports CAT I was thinking is there any way to add one of the plugs to block it off and then add a resistor of some kind to stop the faults until its mapped out eventually?
-
Well from what I found out from the local mot tester is that eml isnt a fail. Or so he said. What my mate did on his s3 was leave the lambda in but have it mapped out.
Dont know if you cam put a resister in to stop it throwing a light.
Infact im sure my mums s3 doesnt throw a light dor second lambda. As hers isnt reading right but light only comes on when it picks up the knock sensor fault.
-
I'm not getting any lights, its just throwing the codes, I don't want to spend £40 on a new lambda when it doesn't actually do anything because I have a sports CAT, it doesn't appear to effect performance in any way just annoying with the codes. Think I will just leave it in and then eventually get it mapped out, I'm going water meth and bigger injectors soon (next 6m) and that's when it'll be getting mapped again
-
If you remove lamba you wont get a light then mate. So you could do that then as you say get it mapped out when water meth and injectors are fitted
