MOT Failure...Gutted

[trotter]

Yep, the Lady "impressively" failed the MOT yesterday....

Most things were simple enough - a few electrical problems with the lights and so on. However on emissions.....

Wee quick summary:

Fast Idle Test:

CO Allowed = 0.3%vol CO Actual = 7.74%vol
HC Allowed = 200ppm HC Actual = 850ppm
Lambda Allowed 0.97 - 1.6 Lambda Actual = 0.8

Natural Idle Test:

CO Allowed = 0.5%vol CO Actual = 8.52%vol

Now methinks the MOT man put me through the wrong test, \'cos I thought a \'93 Import only had to do the 3.5% CO test?? (which I still would\'ve failed)

Anyhoo, theres no cat and/or lambda sensor so I need to get a hold of them...Any ideas???


PS: When talking about a pre \'95 import, I assume it means that the car was manufactured pre-95 not imported before then?? Sorry for thick question!!

[grinder]

you MUST have a lambda sensor - or surely your car would run mega rich all the time

[trotter]

thats what i said, but apparently its not there???

If you\'ve got a standalone ECU you can just run open loop all the time - so no Lambda required - but those emissions seem awfully high !

Prof T has apexi ecu

Reckon that\'s deffo the wrong test they\'ve given you, if yours is a \'93 import it should be the pre-cat test, 3.5%CO and 1200ppm HC. Is the Lambda sensor not on the downpipe?

Hi there

I failed mine yesterday also, mine is a 92 import and I got the 3.5% vol CO test.

My results:

CO %vol -     6.798 FAIL   LIMIT - 3.500
HC ppm vol - 2880 FAIL    LIMIT - 1200

Do my results from the Hydrocarbon test indicate anything? :xconfused

Also failed on lights and upper coil spring mounting is damaged and weakened.

Back to the drawing board!

lol, nice work mate. Fancy going out to celebrate single-handedly killing the world?? :driving :Hammer

Ummmm, if you have imports, then they are not part covered in the MOT Emissions test (version 8 or summat) that they use to check.  A UK car has a different VIN number, and that is what dictates the figures to use.  Certainly 5 years ago, they didn\'t list it in the book, and as such it\'s the higher figures quoted above - if you\'re friendly with them, I\'d get them to show you the entry in the book that they used, and show them the error of their ways...

Otherwise, new plugs and leads, take it for a right good spanking before, and get them to do the emissions on the hot engine - suddenly everything is right...

[CraigWWW]

I got my emissions sorted a different way... £50, back pocket....get it?

[peterwolds]

told T that i should still have a dunk megaphone exhaust buried in garage which i think is catted he could use to get through mot plus could borrow my commander for the day to reduce fueling for the day to pass mot - wont that help ?

[FDAsh]

There\'s a thread on FD:UK about adjusting Power FC settings, not sure how effective/safe for the engine it is...

T mine failed today same garage as yours,wife took it in for me they used wrong test - did you ring up to complain ? i intend to,passed last 2 years there no problem diferent person tested
Catalyst equiped vehicle with closed loop control
fast idle
co 0.3% vol did 0.35 fail
hc 200ppm did 31ppm pass
lambda 0.97 to 1.6 did 1.26 pass
passed 2nd idle test 0.23/15/1.25
natural idle test
co 0.5% did 1.39% fail
exhaust gas test not successful permission denied
comment:# engine speed measurement was by-passed
also failed the lights "nearside & offside (no beam pattern) headlamp not in good working order adversely affecting beam image
:Grrr:Grrr:Grrr

Mine runs n 850 injectors all round and no cat, always fails the emissions and comes up with the same 7% CO reading. The PFC has been adjusted by a mate to get it through last time.

I\'m not convinced it\'s possible to get it through without tweaking the Power FC or putting the cat back on.

Was thinking about changing back to standard primaries and larger secondaries to see if that makes a difference.

You guys need to find a garage that aint bothered about emissions.
