Parking system error

[dsolds]

HI All, 

Wondering if anyone can help please?

Optical parking system, Superb 2014 Estate / Combi.

The parking system throws a fault at start up. I get a long error beep. What isn't clear is where the parking sounder is. VCDS shows the below but I'm confused as to where the long beep comes from if the parking aid speaker is supposedly dead? Or is the error beep coming from a different sounder?

Thanks for any pointers.

Dom

Speaker is dead and its under the dashboard on the passenger side buried in the centre console.

Cool, thanks for this.

 

Are there any diagrams to help? Got half the car in bits but can't see it. I found the one up behind the instrument pod and that works OK. Just can't seem to find diagrams for the estate. Thanks.

OK, found it up behind the headliner at the back. Awkward to get out but it’s definitely duff. The front one measures 49 ohms, the back one is open circuit.

Just to add, in case it helps someone out, it was quite a bit of a mission finding the parts on the car, not a lot of diagrams out there for the estate version and some erroneous information as well. Where the car has front and rear sensors it also has front and rear beep speakers. Front is behind the instrument cluster and well documented. Rear is above the headliner at the rear of the car and can't be seen by just pulling the headliner down a bit. The main rear box section supporting the roof has it mounted on the forward facing surface towards the right side of the car (driver's side in the UK) so it's quite hard to get at without removing the headliner. Same 2 plastic rivets as the front one which you can push the centre right through with a small straight Torx driver or similar, at least that's what I did. Refitting was done with a double-sided sticky pad.

remove the 2 D pillar trims by pulling off (away from the D post)

gently pull the headliner down enough to get your hands in and feel for the speaker. If you prop the headliner down a bit with a torch or similar you can look in the side window to see the speaker. Don't pull the liner down too much or you will crease it.

I used a T10 Torx driver (nice and thin) and used it to push the centre of the rivets right through. This means the rivets are then no good as the centre bit will be lost in the box section forever. You are effectively pulling the driver towards you unless you really do want to take the headliner out. 

One of those mirror mount pads for the windscreen was used to attach the replacement speaker.
