decat, 16804, 16795, 17705

After changing hoses and pcv pipes the 17705 has retyrned... Next step tb clean and reset.
Fitted 3" downpipe and a 2 1/2" toyosport stainless exhaust with decat last week. Car feels loads better but chucked eml on today with 16804.
I did use the lambda sensors that came with the exhaust is it worth leaving see if it returns or just put my old "known good sensors" back on.

Did you fit a O2 spacer on the decat?

 

[mill5y]

It was fitted as it came, taken from a leon..
Couple of pics if these help,

Not sure if you can make it out or not. Its had some welding around the decat part..

You can buy a spacer to space out the post car lambda sensor which should cure the EML coming on.

Lovely.. by spacer you mean like an extra piece if pipe to insert in front if sensor??

Yes it's a little bracket. I bought mine from Awsome GTI, but if you search eBay you'll find them there also.
