Arg MOT fail! :-( - Lambda reading

Post by Scottd » Thu May 11, 2006 3:25 pm

It only failed on the Lambda reading, the CO and HC were fine. Do I need a new lambda sensor? :-? If so where's the cheapest, Rover in Dundee want over £100 :shock: Not entirely sure it's the right one tho.

My flexi section is bust tho (it failed on that too), could this be affecting the lambda reading?? :-/ Was planning on fitting a new fexi soon anyways.

cheers

yes the broken flexipipe will let in air and cause it to fail the emissions test.fix the flexipipe and get you car retested it should pass ok

To clarify, even though your car has a lambda sensor, the MOT tester is not checking your lambda sensor but rather the O2 content of the exhaust. As you have a hole in the exhaust the extra air that is drawing in is making the O2 content wrong. Having said that, I cannot see why it would fail on too much O2 ... as we discussed on the telephone, what's probably going to cause you to buy a new Lambda sensor is the fact that you'll end up changing in the exhaust manifold and the old one won't come out withough WMD ..

Cheers,
Robin

Out of interest, where are you getting your MOT done, Scott? The Arnold clark MG/rover place just off the Kingsway? I'm due an MOT in a month or two and would like a garage that won't destroy my beautiful beautiful car. :?

Scott how busted is your flexi? I have one with a knackered mesh bit that tizzes a bit, but it looks gas tight if you want it.

And you think AC is the best place to take it?
:ROFL
Avoid at all costs or you WILL regret it :thumbsup
I've said before about servicing and didn't know if they done any but I know that the Proton dealer has definately done MOTs on Elises. There's also the place that Lee recommended on Fairfield Road I think but dunno if they do MOTs. A guy at work also told me he saw an Elise in a garage near the Mosque down from the Globe, can't remember the name of the place tho.

Nah, I tend to avoid official dealerships like the plague, the only reason I asked about that place was because Scott mentioned they wanted £100 for the sensor, wasn't really sure if that implied he was getting the MOT there too. I'll bear the proton d****r & Fairfield Road place in mind tho, cheers!

If you are going to buy a sensor I got one from "Reid for Speed" Cotton St Aberdeen for £43 inc the vat.

Had the same problem with mine a few months back, Co2 high.
Got the new lambda for 40 bucks from a motor factors & also found holes in exhaust. Changed both just to be sure. Lambda is an interesting job, be prepared to bleed profusely. I think it was just the exhaust but I thought I'd best be sure as its a pain having to go back for the third time if it fails again!
got lambda from WD autofactors in Dunfermline. A bit of a treck from Dundee though.....

Dundee - Dunfermline = 30 mins, not that much of a trek ;)

Rich last time I looked at mine it was the same, but the Elise Parts exhaust has been vibrating the fek out of it. It certainly sounds much worse now anyways.

I've been talkin to Robin about it and he's given me a few options. I'm going to try the cheapest option first, and 'just' replace flexi down pipe w a st/st job.

Unfortunately cause I shouldn't really drive the car and don't want to pay anyone else to do it (an let em have all the fun!!! ;)) I'm gonna have to do all this under the car on me drive way. That'll be interesting on a 7 year old car heh!!! :shock: I'll be sure to let you know how it goes / what I've broke :)

Yea I wouldn't touch Arnold Clark. I'm going to a place that used to be very 'friendly' but now due to all the computer stuff they have to do, it's just like going anywhere else :roll: For the first time ever I had to pay for the MOT even tho it failed!! But at least I get to hang around / help with the test while he's doing it, so can keep en eye on things. For the re-test I might go somewhere more local tho. There's no where I'd particularly recommend but I think there's a place on fairfield road off clepington road where Lee used to go. So that'll be what... 6 Elises they've delt with!? :D
