A2 3L / Lupo 3L door switch

Hi,
I am looking for the switch that allows the hydraulic pump to start as soon as you turn the key of the door or open the door ( that is the case with my wife's A2 3L).
Whereas my Lupo takes forever to build pressure.

I have also bought the universal remote opener with the hope that the pump could start even remotely before even opening the door.

Any suggestion is welcome.

Thank you
Nader.
 
Hi
If the pump takes a long time to build up pressure it’s usually caused by a failing accumulator and/or low oil level. Or the pump itself has internal leaks.

How old is the accumulator? It’s stamped on the top.

If the pump doesn’t start when you open the door the switch in the door lock is faulty.

Hello Thomas,
Thank you for your reply.
I can't see any other marking on the accumulator than this : M2WC20012.7

Definitely the switch in the door does not work.

I wanted to double check the specs to order the right one.

Also it would be so great to get the accumulator to start with a universal remote opening. So it starts pumping even before you open the door!

Wonder if this is possible...
 
for remote opening are you saying that the car unlocks by remote or the doors physically open? Asking this because the door has to be physically open for the door open microswitch to start the pump.
 
I agree. This would be the normal function.

Wondering if it is possible to install a relay or so to simulate door opening or turning the switch to start the pump...
