XUD Cat / Lambda - adamm306 - 01-08-2013
Hi guys more noob questions... god forbid when i start fiddling with the pump soon lol
Where is the cat located on the XUD is it in the manifold like the 106's i looked underneath and couldnt see anything only a middlebox
im pretty sure it is catted though as it has a lambda sensor but this isnt plugged in? is this a sign of a decat any negative effect having lambda unplugged?
be nice to me im new

A Xud doesn't have a lambda sensor. And the cat it on the down pipe as you look at it just back from the subframe. Though some early Xuds don't have cats.
Get some pics if you can
Re: XUD Cat / Lambda - vlj - 01-08-2013
Early XUDs don't actually have a cat, but if it does it will be coming out of the subframe area then joining onto the start of the centre pipe.
You'll also find a severe lack of a lambda sensor on an xud cat
RE: XUD Cat / Lambda - Midnightclub - 01-08-2013
1) It doesn't have a lambda
2) If it's a Phase 1 it probably doesn't have a 'cat', some came with a decat out the factory.. but if it does have a cat it'll be engine side after the centre box
EDIT: no replies then 3 at once haha
RE: XUD Cat / Lambda - adamm306 - 01-08-2013

Its not in the subframe, the cat itself is visible from under the car without looking up inside the subframe area.
RE: XUD Cat / Lambda - Midnightclub - 01-08-2013
Is the car modified? may possibly be an EGT probe?
RE: XUD Cat / Lambda - adamm306 - 01-08-2013
no its completely standard dont think the fuel pump or turbo have ever been touched its on a N p1 so it may not have a cat
ill take some pics on my break and report back lol
RE: XUD Cat / Lambda - adamm306 - 01-08-2013

RE: XUD Cat / Lambda - bigcheez2k3 - 01-08-2013
You're looking at the front of the engine, the exhaust comes out the back.
RE: XUD Cat / Lambda - DarkInferno - 01-08-2013
take a few steps back
your 'egr' is your glow plug relay.
RE: XUD Cat / Lambda - adamm306 - 02-08-2013
Haha whoops... My bad anyone know what that connector is for though? And cool thanks
RE: XUD Cat / Lambda - con67 - 02-08-2013
The first pic is the oil switch and the blank connector could be for aircon clutch
RE: XUD Cat / Lambda - adamm306 - 03-08-2013
hey guys didnt wanna start another new thread really quick question
was following this vid
http://www.youtube.com/watch?v=X4l5on3_IrA
he doesnt mention when screwing the boost compensator on the bosch if its between 1.5-2.5 screws in or screwed out? which one is it i ended up screwing it in as the max fuel one goes in aswell if its out ill have to go change it lol
nevermind sorted it
RE: XUD Cat / Lambda - adamm306 - 03-08-2013
Hey guys was adjusting the Bosch earlier screwed it in quite far and ended up having it idle at 2k rpm so turned it down a bit and was idling at 1.8k so turned it down again etc untill it idled correctly is that the right way to do it?
Feels faster now and smokes a little bit but don't know of I'm just feeling a placebo effect lol
Boost gauge comes Monday so can see what's its boosting and adjust to suit...
RE: XUD Cat / Lambda - DarkInferno - 03-08-2013
tur the fuel up... turn the idle down.... till you get more smoke then you want.... then turn the fuel down a bit and set the idle....
the lda should be wound out as much as possible.... the seat for the spring should be wound out slightly (if you want to bother with it)....
RE: XUD Cat / Lambda - adamm306 - 03-08-2013
Yeah lda is nice and far out ill try again in the morning and fiddle with the idle thanks for your help I feel a bit clueless
RE: XUD Cat / Lambda - adamm306 - 04-08-2013
tried to adjust the idle today but the hot idle screw is in a awkward place to get to how do you guys manage to get to it without removing the pump?
