Will this be an MOT failure (re dash)?

I have tried two sets of 5JJ R1 clocks:

Original set: Doesn't display correct speed (always 0mph) on the LCD display. But no error codes.
Newer set: Displays speed, but has an 8000rpm self diagnostic needle bounce every few seconds (relates to fuel sensor issue - first set of clocks suggests the fuel sensor is fine).

Will either or both be an MOT failure? I'd rather get the car on the road asap so I can have a few more days driving the damn thing, and I can live with the needle bounce for the time being.

Speedometer and rev counter are not part of class 4 MOT test





How long can i resist the temptation to drop a V8 in?

Oh jeez that's annoying, I had assumed the speedo not working was a certain fail - I hadn't gone for an MOT for that very reason! Time to book an MOT on a dry day.

Speedo not working was brought into the MOT in 2012. Tacho isn't part of it though.

"Reason for Rejection:
1. Speedometer not fitted.
2. Speedometer incomplete, clearly inoperative or the dial glass broken or missing.
3. The speedometer cannot be illuminated."

The broken glass only applies if it is a danger, could foul the pointer or could be misread as the pointer.

Interestingly:
"A Tachograph is an acceptable alternative to a speedometer providing it satisfies the requirements of this inspection."

Realistically, a tester won't ever move the car quickly enough to know whether the speedo is working or not anyway. Or at least they shouldn't.

They may well do with a kit-car. My local place decided that the low ground clearance was a risk with their brake rollers, so took it out on the road with a deceleration (Tapley?) meter.


Also commonly used for permanent 4-wheel drive vehicles that should not be tested on normal brake rollers.

Wrong, with a kit car even if the weight is known it is not on the MOT database so roller readings are not acceptable.

I'll put the clocks in with the working speedo just in case.

My thoughts were that often something which is fitted to a car must be working. I do get the correct rpm for about 2 seconds every 5 seconds or so, so that's kind of working? And the error relates to a fuel level sensor which I highly doubt is tested anyway.
