MOT scam?

MOT failure on two tubeless tyre valve stems!



Refit tyres and re-balance plus £2.00 each valve. No air loss, no visible perish damage. Not projecting far enough for kerb damage.



Not expensive but provides work for their tyre dept. who might be having a quiet day.



I know faulty pressure sender valves are a fail but not found any reference to this on a simple search.

Not come across that one.

A few years back, two years running, I had bulbs fail between the car leaving home and the test taking place.

What are your tyre pressures?

High pressure tyres need a reinforced valve stem.

The only time my motorcycle failed an MoT - and I’ve owned it for 35 years

- was due to a headlight bulb failure between leaving home and racking up at the testing station.

I received a response, but to my email account. Which, surprisingly, is a valid address.

From a thunderbird user? MZLA have put out a feeler on whether people would like the "second" reply button removing, which is basically what confuses people intodoing that ...

I had a rear seat belt extended, twisted and put back into the reel housing, effectively jamming it

I had to buy some weird pointy socket thingy to remove the panel to untwist it...

I seem to be running an addon that removes it from the news client

I once had a rear middle seat belt MOT fail. It turned out that if the rear seat back wasn't correctly in the locating clips the seat belt couldn't be extended (locked up). Prior to the MOT i had been running with the rear seat folded down in order to carry a large load. A quick tap on the seat back and it fully clipped in to the locating lugs and the seat belt worked correctly again.

Oops. Holidayitis!

Diesel Fiesta. 33psi front rear depends on the load 27-33 perhaps.

Coincedentally I had a headlight bulb go on the way back from an MOT which the car had just passed.

So. Has anyone had a threatened failure due to aged tubeless tyre pressure valves?

You can appeal the MOT fail to the DVSA if you think they playing silly buggers.

Hmm. I needed the vehicle to get home plus, it is the wife's car and we have a visiting friend to cart about.>

Right. Further searching produced this:

Under section J it says: A tyre valve seriously damaged or misaligned likely to cause sudden deflation.

I should have asked to be shown the problem as they seemed OK when I checked the pressures before the test!

Oh well.>

Exactly the same issue I had with my 59 reg astra estate.

The centre belt was interlocked to the seat back retaining clips, preventing middle seat usage if the seat back was not fully clicked back. Over time, the heat of sitting in the sun with the seat backs down, dried up the grease in the ?bowden cables connecting seat locating clips with the centre reel, which duly locked itself full retracted.

Expensive MOT failure, even though I never carry back seat passengers !.

+1. And I did once, and they got a rap on the knuckles too
