new mot
#21
All engines should be warm when doing the MOT as it's the 'running state' pollution they're interested in measuring, not 'cold startup' as it would be impossible to measure that correctly anyways. (Even drving an ice-cold car into the testing bay would invalidate the test. )

Broken front spring...
If the car has the retrofit 'sleeve' on the spring, it may be safe to drive at low speed. But cars without it will sooner or later rip their tire open. That's in the case where the end shifts towards the tire. It can also end up rubbing against the mount where the brake pipe connects to the flexible hose... (at least it can touch that on my M49. I saw that myself when my RH spring broke. Don't know if the sleeve will protect that also) and I don't need to tell anyone what could happen if that pipe is cracked...
Also, if one breaks, remember to swap the other one at the same time.

There seems to be some confusion as to 'MOT validity', that many thinks that just because a car got a 'clean slate' on the MOT, that the score is 'valid' for the next 2 years.
It's not. The MOT is a 'point in time' test, certifying that at THAT EXACT MOMENT the car is 'safe' to drive and without undue pollution.
for such a test to be for a period of time, they'd need to do a much more invasive examination, checking the internals of parts, possibly using ultrasound on others, checking the oil for traces that could indicate coming issues, doing the same to the coolant, brake fluid, servo oil, and comparing the results against local weather, your driving style and so on.
They'd also need to put on 'seals' on the wheel nuts, and the engine compartment, and require that the windshield viper filler spout be outside so that no tampering can be done to any vital systems.

The most you can hope for is to ask the mechanic if there's anything he would recommend that you do something about before the next MOT.

A bit of a rant, but...

Does anyone know for sure if the EML staying on means an MOT fail?
I looked through the testers manual but can't find any mention of it there.

Update:

Yes, seems that it does mean a major fault & so a fail on both Petrol & Diesel engines

Found this on the MSE web site

RFR 8.2.1.2.h for petrol, RFR 8.2.2.2.g for diesel in the manual that comes into effect on 20th:

"Engine MIL inoperative or indicating a fault"

Guess you're going to have to plug in your EGR valve before the MOT then. . .   Wink

I see you've been reading my other posts Smile

Yes, in fact I plugged it back in yesterday to see if things would be any different. The EML went out but straight into limp mode, took me about an hour to get it running 'normally' again. I think I'll need a new MAF before the MOT but may ask the testing station if they'll do the whole MOT first then the EML on a re-test in case it fails on something else first.

Yeah we've had a few discussions on the EGR subject.

What are the revs limited to when in limp mode?

You could take if for the test in limp mode with the light out, it may pass

It will rev up to 2750 in limp mode, it should be enough for part of the test which talks about '2500rpm or half the maximum whichever is the lower' but it's a bit unclear if they need to go past that for other parts of the test. I'll give them a call in 2 or 3 weeks to get their view. My MOT does not run out til 19 Aug, but would like to get it out of the way in late July.
