failed mot on emissons

(1/2) > >>

landroverkeith:
:evil:  lindas freebie failed the mot on emissions as they were wayyyyyyy above the limit. we had a new cat put on few months back surely a new cat shouldnt fail this high?

the garage we used says they need to test the cat/ lambda sensor as its not working they dont have the disc needed or summat. asked us to try landrover for diagnosis (if thats how its spelt) erm noooo luckly a local expert says he has this disc so ill be going over there tuesday after my mot  :roll:

if this new cat is at fault i presume i can return to fitting garage and demand a new one fitted under the warrenty etc??

carbore:
Hi,

Why did the old cat die, if its not expected then perhaps your engine is kicking out too many nasties that killed the cat (an maybe have again)

Anyway its better to start at the front, with the engine, rather than the cat which is at the end.  I wold look for a sensonr failure, lamda, tps, Idle air controll or even ECU.  IS it a 1.8petrol?

Try taking it to an independant rover dealer as they can run diags on it no problem.

Also make sur the vehicle is serviced, air filter, plugs, oil etc. I ahd a golf tat had a cracked aibox and that maid the engine fail on emissions

landroverkeith:
serviced every year i know thats prob not enough but the car drives like a dream

and according to the guys test machine yes he does suspect a lamda sensor has failed im sure he said it was the 2nd one as the first one moves up and down to suit the "nastys" and the 2nd one should read pretty level as it comes through and out??? lol i dunno

not sure if he was just slagging off other garage but he was pretty adiment that they should have suggested fitting a new sensor with the cat? is the right or just grease monkey bitchness lol

fudge:
Depends again on how the cat failed..... as a trader it's really dificult with this stuff, your damned if you do and damned if you don't.... if you suggest the car needs a new sensor 10 others will say not to bother, they're just legging you up!

Get the sensor out and clean it, run an injector cleaner through the system stick a tank of Super Unleaded in it and take the car for a damned good thrashing up a dual carriage way.... no a propper hiding not a trot...

bet it passes with the old sensor.

Minotaur:
Keith

did you get the emissions sorted?
If so what was the diagnosis, and cure?

If not, try contacting the Forte Technical Helpdesk - they deal direct with hundreds of Land Rover Dealers, independents and the manufacturer.
Phil or Dave on the helpdesk are both very technically knowledgeable - they should be able to recommend acure and probably a competent local garage.

Let us know what happens
