I have a new GLC AMG PREMIUM PLUS and the Parking assistactive does work. I discovered that all ZHLC from September 2020 have been disabled. However it can re-enabled by a company in London and they can even do it remotely. They are called RJ Auto. They have a website.

Doesn’t work

I was going to say that :D

Welcome.

Sadly, the deactivated active parking assist can not be reinstated.
 
Good luck OP. Do post back the results

Since the feature is available on other markets, MB would not have removed the software but disabled it simply by coding. Most likely the feature cannot be activated by an MB dealer, they are not allowed to change the related VeDoc settings which would be needed for on-line coding.

Some hackers however use development tools and can change the coding. It just needs pretty good understanding of "poorly documented" parameters on multiple control units. The car should neither visit a dealer for service on related control units, they would revert the car back to previous. Nothing serious harm other than the hacker would need to perform his magic again.

I essence they produce a hacked version of ECU software, it is then uploaded to the car via the OBDII dongle they send you by post, and it overwrites the original ECU software.

I am aware of the process, however I would have thought that MB are aware of this practice (is has been around since OBDII ports became standard over 20 years ago) and ensure that the removal of this feature includes a change in hardware as well.

And, what about potentially invalidating the insurance? I can't see how you can declare a modification that contravenes a mandatory directive (technically rending the car unroadworthy). But then, people also remove cats and PDFs, so I guess that the risk of being found out when running a car that may technically be uninsured, is small.

ISTR that in another post, @richard mentioned that online coding of any of the Driver Assistance systems is now impossible thus preventing retrofits / enabling of disabled functionality.

Prevents retrofits by official dealers, not for everyone (I'm not able to do these but I've got enough understanding how it is done). Since comandonline moved to official tools, they would not admit doing unofficial tricks, I assume they don't do it (some official workshop do).

Can’t think why anyone would want Parkassist, it’s bluddy terrifying. I have it on mine, it snatched the steering wheel out of my hand quite violently and proceeded to park the car, couldn’t get my foot on the brakes quick enough :eek:

Most of the very tricky retrofits and modifications are only done by the experts themselves, not remotely.

I bet the majority of special OBD activation tools do not upload any new software but behave like a factory development tool and send a sequence of commands to the relevant control units via the OBD port to change version coding of these units. This approach does not work if the new feature asks for new control units to be installed.

In case of engine tuning or similar tasks the control unit SW is actually updated. Quite a complicated task to create a file that the existing control unit accepts (obviously even more complicated to define SW changes to gain performance).

I don't have to be concerned about insurance, the features that are claimed to be not allowed by the UN directive are active in my country in the most recent models and my country is a member of UN (and EU).

Generally our dealers have a very reasonable position towards retrofits, equally our insurance companies. If a specific feature is allowed in one car, it would not invalidate insurance or warranty on my car if it was retrofitted. Most often these features increase safety, a properly implemented parking assist would. I understand that drawing the line may become difficult but common sense makes more sense than ruling out all changes for the sake of simplicity.

You should never sit at the driver's seat if you are not prepared to apply brakes "quick enough". Control the car speed if you want to avoid the steering wheel spinning too fast. If you (and me) cannot master it, it doesn't mean the feature should not exist.
 
I thought the directive came from the UN, so would be global?

I guess it only applies to those countries that have agreed to make all UN directives mandatory? Not sure if being a UN member state means that you automatically accept all UN directive, but if this is the case, then I can see a UN Brexit referendum coming up 😱

As for MB... the issue is easily resolved with minor adaptations, perhpas MB chose to apply the required adaptations to certain markets only.

At the very least you'll need to declare it, because you'll be modifying the car from how it came from the factory. If you do not declare a modification, you are opening the door to a legal dispute with your insurer if a claim is made against the policy and they discover that the car had an undeclared modification.

If you do declare it, and there's a claim against the policy, then your in the same situation again if the insurer discovers that the mod was banned by a UN directive.

You might be prepared to have a long drawn legal battle with your insurer, and you might even win, but most people will just give the whole thing a wide berth.

Of course, if there's no claim, and/or the insurer doesn't find out about the mod, then there's no problem. It's only a question of how risk averse you are.

Personally, having been in IT for over 40 years, my appetite for risk is zero, and I have on several occasions bored to death the call handlers at Aviva with the full details of every minor modification I've made, including retrofitting puddle lights to the front doors, retrofitting a boot relase button on the drivers door, etc etc (the list is long :D ) ........

But, ultimately, it's the OP's car, and his choice. That said, I am still not convinced it's actually possible.... I will be watching this space ;)

It may be active in the most recent models because they are specified with the 'upgraded' sensors compliant with the UN directive. That doesn't mean older models, or those supplied with the function deactivated, are therefore compliant

When I say 'I couldn't get my foot on the brake quick enough' I meant my foot hit the brake instantly, not what you are implying :rolleyes:

Sounds a bit like me when Mrs S is driving :eek:
Only kidding........😆

My understanding is that active parking assist is disabled in the UK on a similar car (same model, same MY, same equipment) as my wife's (non-UK) car that has it enabled. Difficult to be sure though.

As I said, your wife's car may have had the required adjustments to make it compliant, but MB chose not to do this in all markets, for whatever reason.
