I need the wiring diagram of pump it has 5 pins coming out of pump

What is the fault code?

You may have two separate issues here. First as for the brake lights not working I'm guessing they all went out at once. If so there is stop lamp switch located on the arm of the brake pedal. If this switch stopped working then you will not have any brake lights. The panel underneath the dash has to be pulled out in order to see the switch. As for the locks not working the pnuematic pump which supplies vacuum for the central locking to work may have either quit working or shut down due to a vacuum leak in one of the vacuum elements. To check this go to the fuse panel in the trunk and look for the fuse for central locking and remove it for a few seconds and re insert. This will reset the pump and allow it to work again. Try the locks a few times to see if they are working. If they don't work right away then you may have a bad vacuum pump for the central locking. The central locking pump is located under the rear seat cushion on the passenger side. Hope this info helps you out if not let me know and I will try to do what I can to assist you.

Pump under passenger rear seat. But if your having issue its the first thing to check and replace.

hello,140 model the centraling pump is in rear seat,220 model in truck,you can replaced the pump,but be sure,no leak in the system,you can use vacuum tester to check all vacuum line,ty

car electrics are a nightmare. the car lights up when a door is open i presume. and by bypassing the central locking. the electric computer says there is a fault. and will not start. that i think is programed in. best thing to do is. go to phone VW dealer ask about diagnostic test without repair. about £35 then fix it yourself. they garentee it right I think. the dealers have come into line better with that kind of thing phone and ask anyway.

Hi, It is not a problem with the pump. Your door lock/latch assembly need to be replaced. Very common on these vehicles.

Hello again, You could now have a driver authorization problem.
1. Plug your central locking pump back in.
2. Make sure that your remote batteries are good.
3. Lock and unlock the car with the remote.
4. Try to start car.
5. If no start you may have to synchronize the anti-theft system.
6. Point remote at the interior rear view mirror, press button on remote twice and turn ignition key key on within 30 seconds.
7. Turn key off and then back on and try to start car.
If car starts, you will need to find out why the pump won't shut off.
You may be able to unplug the pump after you are able to start the car but this I am not sure of.

There is a central door locking pump under the back seat, the motor has gone in it, cheap way to repair is to strip it down and put a motor in it from a tyre compreser from argos for under £10 very easy to fit just two wires
