Title: sudden drain battery drain(HELP)
Post by: eltel on September 25, 2013, 10:49:26 am
hi
I have had my 57 plate eddie for about a year now I bought it from a former member on here, it came with a rns510 fitted by him and all has been well,
about 2 weeks ago the battery was flat it was the original so I replaced the battery, now if I don't use the car on a regular basis it's as flat as a pancake
I had 2 auto elec look at it and both of them concluded it was the rns 510, can this just happen all of a sudden, as it has been problem free for a year.
Is it a gateway problem or firmware. I wish I knew more about cars. :ashamed:
can anyone shed some light please :happy2:

Have your circumstances changed lately, so you aren't driving the car every day or for shorter distances?

It is easy to point the finger at the HU, it could be the CAN gateway, the only way is to physically check the part humber on it or with a VCDS scan. If so you can revert the firmware to a non battery drain one but they are old now.
Would be better off with a new gateway from Eddie-NL really if that is the issue.

I am sire there was a guide for. Temporary fix, by swapping fuses in the engine bay. May have been jedi-knight83 that did the post if you search?

Did they check your alternator?

Sounds like you have to correlate the link between current gateway part nmber and installed firmware.

Post up your location and hopefully someone close wi VCDS can do all this for you with a quick scan.

Has the stereo had any odd behaviours that show it could be failing?

If youve had the rns for a year and never touched the firmware then it must be something else.

Surely you would of had battery drain since day 1.

Get it scanned anyway with vcds just.to confirm what canbus and fw you have. Thats a starting point

Cheers

Hello, I'm quite certain that your car would have the revised canbus gateway, which is at least a 'K' version.  Therefore the RNS 510 shouldn't be causing the battery drain.  Sometimes its the battery that has died and will no longer take a charge!

I've recently had to replace my battery as it wouldn't recharge any longer, even with a donor car attached for half an hour, the charge dropped straightaway after disconnecting the booster cables.  The car wouldn't even fire up with the cables attached!

from what I deduce its the alternator that's at fault
Title: Re: sudden drain battery drain(HELP)
Post by: Llew on September 25, 2013, 05:21:51 pm
Or a dud battery but its easy to find out which with a multimeter
Title: Re: sudden drain battery drain(HELP)
Post by: Llew on September 25, 2013, 05:32:27 pm
If both are sound then look to the starter motor
Title: Re: sudden drain battery drain(HELP)
Post by: eltel on September 25, 2013, 06:57:10 pm
starter motor is ok,it is roughly draining by 3 amps when i take out fuse f19 the loss is 0.5 amps so it is still draining from somewhere?????

I am down your way on Saturday (airport pickup) if you want and can wait I can put it on vcds and if no joy I can lend you my rcd300 for awhile so you can at least be certain wether it's the rns or not
Title: Re: sudden drain battery drain(HELP)
Post by: Llew on September 25, 2013, 07:58:31 pm
Or you can unplug the rns for a while and see what happens

Terry came to me today and I can add more info

Gateway is not the Problem as his Gateway was a 1K0907530L and  the RNS doesn't go into sleep mode

I tried a newer AF gateway, different RNS and new ignition switch all made no difference to the draw on the RNS

There were several faults with the locking system and one in the steering ignition switch (why I tried a new switch)

I'm thinking it is to do with the locking system why the RNS doesn't shutdown

Eddie

How did you check if the RNS was going to sleep or not?
Title: Re: sudden drain battery drain(HELP)
Post by: Eddie-NL on October 05, 2013, 03:06:54 pm
by locking the car with the remote (switching the bonnet catch before)

then using a Multimeter on mV setting and checking the fuse for the RNS

I tested it on my car and after around 10mins would show 0.00mv

on this car it stayed the same even after nearly half an hour

I'd like to test my car out for this but I don't know how to do the bonnet catch trick  :ashamed:on a Seat Leon.

simple

use a screwdriver to push the lever till it locks

check the dash so that it shows as closed

I then release it with the lever before closing it when finished
