KIA Recall Rip Off

 You appear to have ignored that the garage stated that an MOT was only 'visual'. I assume you know it isn't? At the end of the day, folk can pay out good money if they like, their choice.

MOT tests are only visual. A MOT tester is not allowed to remove the wheels to inspect the brakes. If they cannot see the brake shoes or pads because of the wheels fitted they cannot fail them. On some older Vauxhalls even though they had rear disc brakes the that disc also contained a small drum that was used for the handbrake. You couldn't see the brake shoes in this drum without removing the disc so it was possible for a car to pass a MOT with the handbrake shoes worn down to bare metal.

Yes, they are tested for efficiency on rollers (assuming the Kia in question is not something like a Sportage with permanent 4wd). And the standard for efficiency is laughably low.

Just a heads up.
Sportage does not have permanent 4 wheel drive.
It simply directs power to the rear wheels when the fronts are spinning a certain % over the rears. Which is why they have some issues with tyre tread difference between front & rear.

Why did the garage say it needed 2 new tyres? What tread is left ? Is there any cracks/splits etc?  What does , brakes need renewing, mean and did  they tell you why.  What garage is it. how did they rip her off

A viscous centre diff is permanent 4wd. The driver can't select to put it in 2wd.

If you spin one end on the rolling road, the viscous coupling will think that end's simply got wheelspin, and try to lock up to put drive to the other end.

hahahaha  I see a simple piece of advice, that is not compulsary, gives the forum trolls entertainment. Well, carry on kids, and have fun. Be seeing you.

Yes Lewie, the self appointed so-called experts can't wait to nit pick and pull someone's post to pieces. Of course, the forum police will tell you to post elsewhere.

Remember they are home schooling at the moment!

Kia use a "direct electro hydraulic actuator coupling"- their version of the later Haldex unit, stuck on the front of the rear diff.

There is a "wearout-o-matic" pump permanently spinning and keeping an accumulator full of fluid. As soon as the front wheels go faster than the back (in theory because one is spinning, in reality because the front tyres are more worn than the back) a solenoid valve opens and the spring in the accumulator pushes out enough fluid to lock a multi plate clutch and engage the rear.

Keeping it locked and subsequent unlocking is no doubt down to some flaky software (what stops it engaging when going round a tight bend? why would it stay locked?), and I dare say they never thought of it being roller tested either so don't disable the system in neutral

They usually don't work anyway as the pump wears out at anything between 30 and 60K miles if you believe the interweb.
