Audi A3 2.0 BKD 2006 - Will not start unless boot is open #
Posted by Jon Morgan on January 26, 2013, 9:26 am
Year of Manufacture *: 2006 ( Optional ) Engine Code or CC: 2.0 BKD
Morning folks, I have in a 2006 A3 with the customer complaint, "it won't start unless I open the boot & the dash display is dead until I open the boot". The fault is sporadic.
When I first looked at the vehicle the dash display worked & the engine started. I scanned the vehicle & had no comm's with any control unit on the Covenience CAN & had a total of 26 faults logged largely to do with the loss of the Convenience bus.
Opening the boot allowed comms with the previously defunct convenience ecu's & now I have 46 faults logged across the vehicle. I also found that when the vehicle is playing up with the boot shut, if I release the handbrake the dash panel functions all completely disappear (it visibly drops dead) and the engine cranks but refuses to fire. However I can still access the dash panel in 17 & read all data & power supply info & it tells me in immobiliser it has authorised the start conditions.
In Gateway I find that releasing the handbrake switches the convenience bus status's from 1 to 0 - so there is a link between the 2 x earth switches in boot & handbrake affecting the bus comm's.
I found a TPI in work relating to convenience functions messing around when the boot release & handbrake are operated, it usefully advises that changing the convenience ECU doesn't cure the fault - But doesn't go on to say what does :shock:
There is another tpi which advises changing the power supply control unit is largely justified based on returns of units to Audi, but doesn't advise why they were changed.
As yet I haven't been able to get some quality time on it - I intend scoping the convenience bus & power supplies while operating the handbrake & boot contact switches, but when I brought the vehicle in on Thursday to scope the car, it was in a good mood & refused to play up.
Ideas gratefully accepted

Hi Mate, press trip button(left hand one as you look at it) on dash with ignition on and see if lights come on. Press same button again and hold. I fit lights the dash and allows it to start then you have a wake up wire fault. It comes from J533 to j285. HTH Jim
Re: Audi A3 2.0 BKD 2006 - Will not start unless boot is open #
Thats what I was going to say Sean! Check for broken and shorting wiring loom by boot hinge.If not , what if the boot is open but the latch is clicked shut(so the car thinks the boot is shut?).
Excellent tip regards the wake up line James, thanks for that, very handy info. I knew about the wake up line from the J533, but didn't know it could be "hotwired" with a button bash.
Thanks Sean & Colin, wiring checked out okay.
The car hasn't played up for the last few days but I think I may have found the fault - the J393 Central Convenience module at the base of the O/S C- Pillar was full of screenwash from a half detached rear washer pipe union.
