UK-POLOS.NET - THE VW Polo Forum

hi i was called to an adress with a broken lever to open the bonnet and a flat battery.

after opening the bonnet i put the battery on charge and while it was charging i stripped down the bonnet latch and lubricated it and checked opperation of the latch, after reassemble i removed the charger and started the vehicle. customer said all was working prior to battery dying. but after battery was recharged the following no longer works,

horn
electric windows
radio
front wipers
side lights
brake lights
interior lights
eps light on
front fog lights
central locking

the codes i am getting are

03435
03396
00920
03591
01304
00526
16955
b104129

i have tried terminal 30 reset and have cleared all codes i have removed all fuses and checked continuity and checked power in and out of all fuses. any help would be very appreciated.

polo is a 2011 and a 1.2

So all the fuses have power, or are only continuous? What is the voltage on them? 12V? Battery still alive? Car starts? Alternator OK?

yes power at all fuses, battery charged up, alternator works, and car starts, rear wipers work, indicators flash when central locking button on key pressed, front dip and high beam work, reverse light works, front screen wash jets work

Do you have a scan with vcds or something similar?

i have a scan with delphi and it is just giving code i have put on all relating to power from terminal 30 but all fuses are ok

I see. Indeed I googled your error codes and they all show problems related to terminal 30.

If the fuses are all fine, I'm wondering what else... Grounds fuses BCM all checked?

bcm is what im thinking possible groung issue, when i put computer on and check live data the computer is showing that the windows and wipers are working but they do not operate.
these are the 2 codes that wont clear
03435 interior light/ parking light
03396 central locking
