[Benziner] Polo 9N AZQ lässt das Gas beim Schalten stehen | Posts 16+

Hello Ulf,

I've only tried it without using much force so far, but that didn't work.
The black, round part is minimally rotatable within the blue casing, and that's all it does. Sure, I will.

Currently, I'm troubleshooting an issue with the brake pedal switch on a Golf. It's a sporadic fault on sensor G201, with the additional code 008, which, according to the error database, indicates a problem with the brake light switch. However, it is currently not being produced anymore, so the switch (~8 €) is only available in limited stock.

There's a lot of switch failure happening right now ...

//edit: Or are you only referring to the removal of the pedal bracket? That's easily done. According to the repair manual, however, the switch should not be used after that, because it will no longer provide a secure connection. The newcomer was already very well-fed.

Yes, that's exactly what I meant: it seems that some kind of locking mechanisms or similar components wear out or become damaged after just one or two assembly and disassembly cycles?

That's quite possible, I haven't tried mounting a second derailleur on the pedal bracket. However, removing the old part was easier than installing the new one...

Do you have a crafting activity planned for ?

No, much simpler.

Safety-critical components must only be installed once.
The brake light switch is defined as such.



There's also a "great" part in the Phaeton.
The hazard light switch.
It belongs to the multimedia unit and should not be installed again.
These components are called DMBA parts. All assembly work performed on them must be fully documented and (permanently) archived. Therefore, the name: Documents with Special Archiving.

No, I'm just asking as a precaution.

Okay... could you summarize in a few (general) words which other parts of the entire vehicle are included?

And since when / from which model year does this apply?

All parts that the repair manual specifies. These components are already defined as such during the approval process with the KBA (German Federal Motor Transport Authority).
The brake light switch is always included. There are similar regulations for almost all parts related to safety (seatbelts, airbags, etc.). If a DMBA part is explicitly designed for disassembly and reassembly, this will be mentioned. In the past, brake light switches weren't made of easily damaged plastic and were more robust, so they could be reused after being cleaned.

1937... Since the introduction of vehicle type approval.
However, it is only in recent times that this has been paid very close attention to. Particularly with components that can suffer "imperceptible" damage during disassembly, such as plastic brake light switches.

Aha, thank you for the clarification, on my part as well .
But does that also apply to clutch monitoring - surely it wasn't installed in 1937 ?
