Speedo.

 

Does it have to be fully functional for the MOT or will having a GPS speedo in place of kippered OE one suffice?

[HillmanImp]

Do they test the speedo? I have not had a functioning one on several cars and they have passed. How will they check it, they dont drive anywhere?

[Albert Ross]

Make sure the light works and that the glass is not broken. Agreed, it should fail if inop.... but like said, the only way it MIGHT work on test is on the brake rollers. You'd be unlucky to see it fail. Also, if the mileometer is knacked, then leave the old certificate at home. The only way the tester will find out then if it's been fucked for a year, is when the new certificate is printed, and that's too late. (Also not a fail, because that's a mileometer, not a speedometer.)_

Speedo just has to be present, illuminated and not "clearly inoperative".

There was a story years back that an MOT garage used what they thought was the speedo on a Lotus XI to check the brakes.   Banged 'em on at 30 (3000rpm) by which time the car was probably doing nearer 70... Certainly, my Cowley passed with a floppy speedo so I  guess they don't bother that much.   Mind you the Minor passed  with a shagged chassis leg so you do have to wonder.....

We had a great thread started by SOC back in the day; very helpful:

I call 'balls' on the Lotus story seeing as the tester doesn't accelerate on the rollers. The rollers do the turning.

Cheers chaps.

 

Looking at a B series Frontera and one of its faults is a kippered speedo ( they all do that sir) but the present owner has and is including a GPS speedo.

 

That said, there is a nicer looking one on the bay for less money and less miles so Im considering that too (linky)

You can fix the speedo relatively easily if it's the usual - 'only works with sidelights on' fault.

For the last couple of years my older cars have been taken for a drive with a Tapley meter to test brake efficiency for the MoT. Before then they were always tested on the rollers. Is there a reason for this, or just because the testers fancy a spin in the vintage cars?

If the tester cannot determine a vehicle weight for the brake test then section 3.7 of the manual gives them the routine to follow.

 

Firstly do a brake test in the rollers and if more than 50% of the wheels on a given brake (service and parking) lock out then it passes. If this doesn't happen then the tester should use the decelerometer to complete the test and gain the efficiencies.
