After years of trouble free motoring and everything working as it should i leave the car while I'm away for four days and the aux battery dies, no biggy I order and fit the new one and now I'm at a dead end with lots of problems.
The radio works but has no sound, the parking sensors work but again no beeps, clock works but I can't adjust the time, Sat nav not working, half the dash info screens missing and the electric boot has stopped working.
I have looked at previous posts on the boot and tried several of the methods but nothing, I hoping some one knows a really simple fix before I start ripping the car apart as how a dead battery caused all this has me stumped.

First posts normally go in introductions else you could get a free fix and we never see you again!!!

Your car spec says 0. Can I suggest that you add your car spec to your signature as it will save users asking every time, if you know the engine code that will also be great? Oh you can't do this of a phone. Adding your car spec

Data Sticker/Options Sticker and Engine Codes

You need to get your motor scanned (preferably with VAG-COM\VCDS) for any error codes logged in the ecu and post them, that will save a lot of guessing and check systems out.

In which order did you disconnect the battery? You do realise that without suitable diagnostic equipment it is virtually impossible to work on this car, don’t you?

Hi

Hi all, another go as I seem to have lost my first into post. After years of being a Jag man when looking for a luxury car a friend and fellow Phaeton owner told me that one would be probably the one of the best cars i would ever own, and he's quite right. It's only the small engine and I did consider the V10 but I'm really quite happy with the small engine performance. My VW knowledge is a little limited but now I'm a member i hope to expand it so I can participate more. Obviously i have a problem which I find i need help with which is now in a thread but basically I parked the car up and 4 days later it's like it's been swapped for a completely different car, from a car that never missed a beat to one with more problems than brexit!

I see you've added you car spec. 2005 Phaeton 3.0 V6 TDI which I would say is:

Manufacturer: VW, Date(s) Used: 05/2004-05/2007, Model: Phaeton, Engine Code: BMK, 165Kw, 224PS, 3.0 Ltr, 6 Cyls, Remarks: Turbocharged Direct Injection (TDI) V6

Yes managed to loose my intro post and the vehicle details when I started, still got there in the end. The spec you put up sounds spot on even though I haven't checked the engine code.
Trying to see if anyone other than a main dealer can scan the car as my one only does the very basics.

hi everyone, hope you are all well. i thought i would add a quick update if anyone wishes to comment please, im not having much luck with the problem.

i took the car for some diagnosis that turned out to be non commital and is just a probably, i cant post the log from the scan as the email attachment was corrupt and there was nothing listed after the vehicle type everything else was just not there, told you i wasnt having any luck!

their diagnosis was that its probably the dash circuit board that has died but this is only a 60% chance of being right? the reasoning is as follows: the vehicle was throwing up an entertainment bus error, the nav unit dosent appear to be getting an off signal and is staying live, the possible cause of the flat battery. the amp isnt getting a wake up signal probably because of this bus error which is why there is no sound. the boot command also im told runs through this bus controller on the rear fo the dash circuit board therefore the common denominator is the dash board, plus they tell me that the tourag uses the same dash panel and these are well known for failing?

this is all well and good except a new dash panel fitted and programmed is well over a grand and thats a lot of cash for a 60% chance of being the issue, i can get second hand ones quite cheap but by the time i have one fitted and programmed it could only be then i find out that either the fault is elsewhere or the replacement dash is just as bad as the one already in the car, its the fitting and programming which costs the lions share!

so any one who is well experienced and willing to comment with some guidance i would be very grateful, oh and just to reinforce my run of bad luck, last night a stone flicked up and broke the windscreen so it now needs one of those two! smile and wave, smile and wave...........

What format is this log via email text or a picture? Ask the garage to send it again?

VAG-COM\VCDS log files are Ascii text which can be opened with NotePad.

You could take a flash drive to the garage and copy your log file over.

By the time I've paid dealer rates it would probably be cheaper to scrap the car and buy another, from what I'm being told so far it's probably going to be my best option. Dont want to as I love the car but I can really do without the hassle.

Modern car electrical problems can be very difficult to trace, the Phaeton just adds another whole level of complication as it is sophisticated but also a good two generations back. Even tough I say it myself, I have ODIS, VCDS and ELSA plus my best subject is electronics and wiring and still those things push my patience and skills to the limit. The Bentley Continental is very closely related and just as frustrating.
