Flat battery problem after installing 9000-1 - any suggestions ?

**vincent** · 30-07-2009, 07:28 PM

Hi

well all is not rosy...got the AVC 9000-1 installed professionally by FHRX, drove the car 500 kms each way in a weekend (no probs) and then parked it for 7 days - would not start - got VW assist to jump start it - drove 500kms in one trip (food stop etc though) parked it for 5 days and it would not start. Jump started it, drove 500kms home and turning it on each day is fine but leaving it 5 days clearly is not.

Dealer has been looking at it overnight ..rang to say the problem seems to be that the VW multiplexing system (?) is looking for the VW radio, cannot find it and hence the multiplexing system will not turn itself off and it is drawing 0.5 to 0.8 amps.

Has anyone heard of this problem or "explanation" before ? Dealer (Bill Buckle) said they did not know whether they could fix this or not.

cheers Vincent

I think I remember when BB only sold Toyota's - same time I used to go to Brooky oval and watch Manly kick arse (I was very young though!).

There is a problem, not common, it seems to be that the earlier version of the Canbus controller does not shut down properly and can cause a current drain issue.
The solution is to measure the current draw about 2 hours after shutdown compared with the OEM radio. There is a VW canbus controller update to solve this problem. but it could also be a faulty canbus in the AVC9000.
Sorry the solution is so technical, but I guess that's why you pay big $ for the OEM stereo.
There is a radio fuse under the bonnet you can pull if you know you are going to leave it sit

When I had that dreaded chip done (

), and had the car hooked up, the system threw up a fault saying it could not find the VW radio (I had the AVC installed). We disabled it so it would not report the fault. However, I then lost steering controls. So we switched it back on and ignored the fault code. Never had a problem with flat batteries or anything. Just a thought that maybe your dealer is disabling it which is allowing the unit to stay on. Maybe ask them if they are doing this, and if so, get them to re-enable it and allow it to report the "fault". It won't hurt anything other than reporting the error and may just fix your problem with any luck.

was thinking about a 9000-1, have contacted Auspack but they arent responding to phone calls or emails.

Is this a common problem?

thanks for the heads up
kind regards

Rob emailed me today so he is on email - no suggestions from him re the battery. Dealer still has the car. For those of you who have used an AVC 9000-1 or equivalent waywell or even an Alpine - was there anything special you had to do re the canbus - I was pretty sure it was just plug & play ?

thanks
