6 in for mot - Billyjames1987 - 05-06-2013
My 6 is away in for mot. I know ill need the airbag light sorted which I know can be a pain. But I also has a slight leak in my inlet manifold gasket. Does anyone know if it will fail mot for that as iv never had inlet manifold gasket leak. Will get it sorted soon as but mot is due this week
RE: 6 in for mot - puglove - 05-06-2013
Shouldn't fail on either of them
RE: 6 in for mot - Frosty - 05-06-2013
Air bag light will fail but inlet manifold leak shouldn't
RE: 6 in for mot - miles - 05-06-2013
Inlet might, It depends on what it does to the emissions
RE: 6 in for mot - Billyjames1987 - 05-06-2013
I know airbag lights a fail nowadays but I know a car sparky that can make it work
for £80.
RE: 6 in for mot - Frosty - 05-06-2013
Do you have any idea why the air bag light is on? You got an after market steering wheel? Cuz its usally just the connections under the seats that play up

This. Any air being take in after the map sensor isnt accounted for by the ecu so may put your fuelling right out depending on the size of the leak.
RE: 6 in for mot - Billyjames1987 - 06-06-2013
Airbag light is on because car was involved in accident with previous owner

Put the XSI in for MOT last month and it was only an advisory
If yours was involoved in an accident prob just wants the airbag control box replacing
Re: 6 in for mot - MartinL - 06-06-2013
Yeah airbag light is a fail, cant even take the bulb out anymore because they need to see it light up when the ignition is switched on :/ and what niall said about your manifold leak
RE: 6 in for mot - Curt - 06-06-2013
It's still down to discretion so no one can say it will fail on it... but as said the air leak could screw the emissions

I work in an mot centre and all cars that come in with a warning light on the dashboard, fail straight away :p sorrry haha
RE: 6 in for mot - Curt - 06-06-2013
Yes... because your MOT station has decided so. It's still down to discretion of the tester!

It is in the MOT rules now. If the air bag light is on it fails. If a tester passes it then they aren't doing their job right
RE: 6 in for mot - Curt - 06-06-2013
Yes, there are many things in the "rules". But it is still down to the tester to decide! It's also in the rules that an exhaust can't be too loud... how is that decided? Discretion!
Also, I'd much rather have a tester "not do their job" and pass my car with an air bag light than mr pedantic. I know my car well enough to know it's safe, just need it legal.
6 in for mot - Frosty - 06-06-2013
But if the light is on it fails. The tester can pass itifI they want but like I said there not doing it right. Comparing it to an exhaust being loud that is more like something the tester can decide on cuz I duno if there is any way to test it apart from what the tester decides.
But I agree with you at the end of the day it is all down to the tester
RE: 6 in for mot - Curt - 06-06-2013
That was my point
RE: 6 in for mot - Billyjames1987 - 06-06-2013
Well will find out tomorrow if it failed or not
RE: 6 in for mot - miles - 06-06-2013
Dead easy to get around light's, Just rig up some veroboard (PCB) and a small timer circuit, Cost's a few pence
RE: 6 in for mot - Billyjames1987 - 07-06-2013
Well failed quite badly. Need some welding, new cat, new lambda sensor, airbag light, inner cv boot and a few bulbs
RE: 6 in for mot - Niall - 07-06-2013
What needs welding? Chassis rail near the subframe mounting?
RE: 6 in for mot - Billyjames1987 - 07-06-2013
Yes. How you guess that
RE: 6 in for mot - Niall - 07-06-2013
Because they all go there. People think its a good jacking point but it splits the weld and lets water in and hey presto, rust! Thats what my last 306 died of!
RE: 6 in for mot - Billyjames1987 - 07-06-2013
Well car won't be moving again until it welded. Just need to source a cat and lambda sensor
RE: 6 in for mot - Tom - 07-06-2013
Sure its cat and lambda? Could be that air leak throwing off the emissions as said above?
RE: 6 in for mot - Billyjames1987 - 08-06-2013
My friend is a mechanic. He fixes up old cars and he said he pretty sure it cat due to how bad if failed emissions test
RE: 6 in for mot - Billyjames1987 - 08-06-2013
Here is my emissions fail results
Co level at o rpm = 3.62% vol fail
Hc level at 0 rpm = 237 ppm fail
Co2 level at 0 rpm = 9.41% vol
02 level at 0 rpm = 4.83% vol
Lambda at 0 rpm = 1.12 fail
Oil temp at 0rpm = 19 degree
N0x level at 0 rpm = --- ppm
Anyone know what throwing emissions out?
RE: 6 in for mot - miles - 08-06-2013
even de-cat'd the emission's are well below that, try the sensor and air leak first

This.
Mine had a test with the decat last week and was well under your figures

Its 100% part of the mot, No discretion at all

How do you know its safe with an airbag light on ? How do you know the airbag will inflate in an accident ?
Legal.... If the police pulled a car over and noticed an airbag light on would they then give the driver a producer ?
