The under bonnet cover is removable by hand, the ‘clips’ are plastic thumb clips. So no change there.

Possible ‘self tapper’ or ‘plastic rivet’ should form part of a pre check, refuse to test if you don’t feel comfortable with the ‘dismantling’ on the grounds there’s no screwdriver or trim removal tool on the tool board.

I do get that people are worried about mission creep.

The liability for any damage will be ours.

Like I said, I'd be happier removing a wheel trim. Politics controls the Fee sadly.

DVSA have always steered us away from dismantling for our sakes.

These changes are forced down from DfT as per

It’ll only be your liability if you broke it, same as anything else. But that’s another topic which I’ve no interest in debating.

3. Parking brakes on Porsche 911 (992) manufactured from November 2021
Some 911 (992) models manufactured from late 2021 are only fitted with one parking brake actuator on the nearside rear.

Check if the vehicle is fitted with a single parking brake actuator
Follow these steps to check if the vehicle has a single parking brake actuator.

Park the vehicle on a flat surface.
Select drive mode (‘D’) with the brake pedal pressed and the electronic parking brake (EPB) off.
Engage the parking brake by pulling the parking brake switch. The parking brake will operate regardless of the system fitted to the vehicle.
If the transmission shifts to ‘P’ (indicated on the central display), it means the vehicle is fitted with a single-actuator EPB.

What you need to do if the vehicle has a single parking brake actuator
If the vehicle is fitted with a single-actuator EPB, you must:

use a roller brake tester with applied brake test function to test the parking brake efficiency – you cannot use a roller or plate brake tester without this function
carry out a gradient test
You must not carry out a decelerometer test.

If the vehicle has an EPB that activates on both sides, you must test it in the normal way. Use a roller or plate tester at speeds of about 4mph.

Testing service brakes
Test the service brake on 2 wheel drive vehicles with a roller or plate brake tester.

You must not test the service brake on 4 wheel drive vehicles with a roller brake tester.


I had the misfortune of testing one of these today ,if you tested EV s like Tesla there's not much to test as you cant see much ,but this one it was a waste of time raising the thing or jacking ,so many covers so you won't spend much time under the vehicle.
As you know if ya have read the special notice section above regards testing the brakes , not entirely adequate as the way it reads it was wrote very quickly in a panic .
It would have great if they told us where and how to operate the EPB switch !!!!!!!!

We have always been told we test the park brake as an emergency brake in case of service brake failure. I wouldn't want do apply a park brake that only operates on one side at speed in any emergency.

I think the car is relying on ADAS for that scenario and a parking brake is literally that now.

I think we've gone full circle on this subject! I vaguely remember back in the early 1990s when testers advised VOSA about park brake efficiency results when one brake did not work and the other brake met the efficiency limit, and back then we didn't have a rfr for little or no effort in them days!

Now the manufacturers have done this and its now ok?

No matter how its dressed up or professionally talked through regulations and justifications, modern vehicle designs (some anyway) are just not safe!

Yep, dead true. Porsche are producing death traps, but that Dynamo guy, he’s got them sussed 👍. Thank god.
