Help! strange behaviour after disconnecting the battery

V8000 · 12-08-2008, 08:12 PM

Hi all, I need your help!

I completed a retrofit BT install in my B7 RS4 yesterday. In doing so I disconnected the car battery for around 3 hours and every since I have reconnected the battery my drivers seat has stopped inflating when I hit the ‘s’ button. My boot release button in the door has also stopped working while everything else in the car is ok!

I ran an auto scan after reconnecting the battery. The strange thing is although it did throw up a few faults (low voltage etc/open mic etc) on a number of channels none were related to either 1) the drivers seat 2) the steering wheel 3) anything related to the boot release button.

Rightly or wrongly (?!) i then cleared all DTC's, ran another autoscan and the car has come back with no fault codes whatsoever and still hasn't 24 hours later.

I've compared scan logs from pre/post mods and all coding etc is the same.

Does anyone have any ideas on why this would happen and more importantly how to solve both problems?

Any help greatly appreciated!!

I take it you've checked all the fuses. Just a thought.

V8000 has posted elsewhere that both problems are now sorted.

The seat bolsters needed re-enabling using the DIS.

The boot release button had stopped working because he had turned the lock to the position that disables the button while opening it with the key.
