Slightly hacked off that the tweaks that are just coming in/just came in to the MOT mean that my dead check engine light is now a fail...So the search for a new ECU continues. Or if it comes down to it, I get more inventive. A single failed transistor is not keeping my car off the road!
There is a fairly major overhaul of MOT coming on 20 May 2018.
Jim picked this up from Pistonheads:

I must look carefully at these MoT 'tweaks' and see how they might affect my fleet...
According to those august fellows across on Pistonheads, these are the main changes...
The 'Minor' is an interesting new category...
How exactly will the brake pad warning lights be tested? And what about many Xantias where the wiring has broken and has been removed?So...
Advisories are being replaced with minor fails. These are all pre written & approved by DVSA. You will still get a pass but they will be noted on your test certificate. Manual advisories are still being worked out but may disappear completely.
Those of you who have changed your standard headlight bulbs for HID's will now get a major fail even if the aim is correct. It has always been an offence to fit HID bulbs to halogen headlamps so the MOT is now in line with that.
Reverse lights are now part of the MOT for any car registered from 1st September 2009 (59 plate onwards). Daytime running lamps (DRL's) & front fog lamps must work on vehicles registered from March 2018 (18 plate onwards).
Engine Management Light is now a major fail. It must come on with the ignition and then turn off when the engine is started.
Brake pad warning lights are a major fail
Handbrake with excessive travel is now a major fail. Before it would only a fail if there was no reserve travel.
Contaminated (dirty) brake fluid is a major fail. Not sure how that will work as the MOT tester isn't allowed to remove the fluid cap.
Oil leaks (engine, gearbox etc.) can be a major failure if they are deemed large enough.
It seems they have removed the failure for tyres not being fitted according to sidewall instructions. Inner/outer or rotation incorrect.
Any modifications/removal to emissions related devices, this includes DPF'S and EGR's is now a major fail.
Where a DPF canister has clearly been cut open and re-welded, it will now fail.
A vehicle fitted with a DPF that emits any kind of visible smoke during the metered test will now fail
Emissions limits for diesels registered on or after 1st of January 2014 have been reduced. All diesels will now need to pass the limit that was set by the manufacturer when the car was new. This can be found on the VIN plate. For example the current limit for your diesel car may be 1.50. That could change to as low as 0.30 with the new rules.
In the Xantia at least, it's not a light that's tested at 'POST'-time like the Engine Management or Airbag light.. In more moderns do the pad warning lights self-test like that?
Draft manual is here
Ref Jim's comment on the brake pad warning light - it's only a fail if the lamp is lit indicating pad wear (or wire failure!).
I'll need to get some new bulbs for the 307 to replace the HIDs.... Interestingly fitting LEDs is not specifically noted (whereas HIDs is) although the fail is Light source and lamp not compatible - which could cover LEDs.
DPF equipped diesels not only have to pass the smoke opacity test, but also 'emit no visible smoke'
I expect though that those who have done the mod will substitute standard lights for the MoT and then swap them back as soon as they have the pass...
