So my recently acquired 2001 tip allroad has a battery drain that prevents it from starting after 24-48 hours.

I pulled every fuse in the car with an ammeter in between the battery and ground. Battery had a fresh charge. I was getting a draw from fuse 17 (Navigation) of .25 amps. I also got a drain from fuse 37 (Radio/Telephone) of .24 amps.

With the door open and all fuses in place: 1.75 amps total
With door closed and all fuses in place: .83 amps
With door closed and fuse 17 and 34 pulled: .20amps

With these 2 fuses pulled I have no radio (duh) and no ability to adjust traction control or the air suspension (warning light on dash also).

I had a local scan the car with a VAG-COM and will post the link in my next post.

What is the normal drain for this car?
What is the best source for a wiring diagram?
What would you suggest I try next?
The driver's side memory seat does not work and either does the heated seat. Related? The VAG-COM report mentions this but my fuse pulling test would not indicate this as a problem.

Thanks!

Did you get the battery load tested??

Re: Battery is newish, unrelated

Rally_nutcase_1982

every new part can always have a manufacturing fault, listen to Ex-PZKW, he knows this stuff.

samm

Did you VAG the car after you pulled fuses? If so then there is no way of telling which codes are a result of pulling fuses and which are real faults. There seem to be way too many faults related to voltage so I suspect you VAG after pulling fuses. If this is the case, clear the codes then re-scan.

paulroad

Then after an hour or so of driving, scan it again and see the 'fresh codes'.
What you showed on the post is a history of prev. faults.

I will have the battery load tested but it doesn't seem to answer the large draw from two of my fuses.

The report I posted was the second report done. First we scanned it, then cleared it, then I drove around the block and rescanned it. All of this was done before any fuses had been pulled.
