Title: Canbus Version for Mk5 Headunit Swap
Post by: RichL on April 23, 2016, 10:04:59 pm
I've got a RCD510 headunit on order for my '07 GTi (to replace existing RCD300).  The canbus part number is 1K0 907 530K and from what I've read I'll suffer the battery drain issue unless I update this.

Am I right in thinking that the last letter of this part no. is the revision number, and that what I need is a canbus numbered 1K0 907 530L (or higher final letter)?

I realise that after fitting I'll need someone to access it electronically and tick the boxes as needed for my specific car, if anyone knows a well regarded independent in Surrey that can do this for sensible money that would be good!

There are members here who sell them pre-coded, so you can replace it yourself without needing a VCDS cable. You need a L or from Q to above.

Excellent thanks that would make it 5 minute job!  Have posted in the wanted section.  Couldn't find anything in either the shop or the 'for sale' forum, probably just didn't see it.

Ok, interesting...think it's supposed to be quite a low level of drain.  Have you ever left car for a good few days without driving (maybe while on holiday), and still found no problem?

Have been thinking that I should just check the drain with my meter with the RCD300 still in place, and measure again after fitting the RCD510.  I can then decide from there whether I need the later canbus.

Not all revision firmwares are compatible. We'd have to see the VCDS scan of the Can Gateway to know.

If your CAN gateway is in the same place as my Edition 30's is (above the pedals), it's a bit more than a 5 min job  :smiley:    I couldn't get my hands up there.  Too much crap in the way.  I had to attack it from above via the access panel under the wiper mechanism, so it's wipers off, wiper mech out....all of it! 

I thought it was just the older RNS units that caused the battery drain?   Didn't know RCDs did it as well!

Could just get my hand through the gap, right pain though, could either see it or get my hand to it but not both at the same time, lots of sharp edges too!

Think I'll get the RCD510 in over the w/e, check the drain situation (I have a meter) then sort the canbus if it turns out to be necessary.

Thanks for the replies!

Does anyone know what sort of amperage I can expect to see on the meter IF the RCD510 does result in battery drain?

so, my number is 1K0 907 530H, it has to be changed?

i replaced it when i upgraded ro RNS, with 7N0 907 530AN
but was thinking of putting it back

Yeap, unless you are going to put 2nd generation unit like RCD300, but if keeping RNS - you must change it.
Title: Re: Canbus Version for Mk5 Headunit Swap
Post by: pudding on April 28, 2016, 01:01:52 pm
It depends on the RNS version as the newer ones can solve the battery drain issue with software tweaks.   I have the original CAN gateway in my ED30 and an RNS510 'Q' and I don't have battery drain problems.   Well, I left the car at Gatwick for 2 weeks and it fired right up when I got back  :smiley:

Post by: Pashka on April 29, 2016, 12:11:23 pm
RNS version doesnt matter, you have to write gateway part of rns firmware to old one from A version. Drain can't be more than 50mA. Rich just measure amperage, if you see battery drain - take the radio fuse out and if its gone - you need to change it.

Indeed the modified firmwares can solve the battery drain without upgrading the CAN Gateway in most cars. Just in a few cases that firmware tweak doesn't work. :smiley:

After installing my RCD510, measured the current draw and found that after a couple of minutes it settled to a reading of zero (on a meter that reads down to 1 milliamp).  Assuming on this basis moment that my version K gateway module is not going to cause me a problem...unless anything kicks back in and starts drawing current after the car has been off for a while?

That's quick to settle normally a higher value - how and where have you introduced your meter I to the circuit?

Disconnected negative battery lead, put meter between the lead's clamp and the -ve battery terminal, meter set to read current across its high-current capacity terminals.  Meter was definitely working - we had readings that reduced in three steps before eventually settling to zero.

Well your values don't match the TSB guidelines but if your meter is working and calibrated then your results say you've got nothing to worry about but that not close to the last reading I had when looking for a fault. :driver:

Have to say (albeit with my limited knowledge), I was surprised to see it absolutely at zero, was fully expecting to see some nominal low draw.  Not counting my chickens just yet!

From recollection (should have written it down when testing on Saturday for accurate account); upon connection got about an amp of draw for a few secs, then fell to 130mA, then to 80mA then after a minute (maybe two from connecting) reading fell to naff all.

I find a twenty minute test gagging the doors and set the alarm so it goes to sleep correctly and 30ish MA  reading if I remember correctly.

So if you have hassle do another test and see what real values you do have. :happy2:

You can check this list of CAN Gateways that are compatible with the 3rd generation radios: http://wiki.ross-tech.com/wiki/index.php/Navigation_System_(RNS510)_Retrofitting (http://wiki.ross-tech.com/wiki/index.php/Navigation_System_(RNS510)_Retrofitting).

You'll need VCDS to know which software version your K CAN has.

Yeah I saw that and mine is not on the list which seems to point to it being compatible although someone said there were only 3 versions of the K which mine is slightly different

0020 not compatible pal, simple thing - numbers shows sw number, higher number higher soft, compatible is only 0178, 0020 is the lowest sw available. if would be option with 02xx it would be compatible.

That CAN-BUS will work with your car and RNS-510. 7N0 is newer than necessary and easy to code accordingly to your car. You'll need VCDS to do it. On ebay 7N0 CAN-BUS are cheaper than on TPS, I bet. :wink:

Look around the For Sale section to check if someone is selling them atm.

You can get a 7N0 CAN-BUS for less than £50 on ebay. There are guides online. For that version is even easier than with late 1K0. :wink:

It depends on the RNS version as the newer ones can solve the battery drain issue with software tweaks.   I have the original CAN gateway in my ED30 and an RNS510 'Q' and I don't have battery drain problems.   Well, I left the car at Gatwick for 2 weeks and it fired right up when I got back  :smiley:
Indeed the modified firmwares can solve the battery drain without upgrading the CAN Gateway in most cars. Just in a few cases that firmware tweak doesn't work. :smiley:

^Interesting, sorry to bump an old thread but could anyone elaborate on what is meant by modified firmware? I have just purchased a version C RNS 510 and changing the canbus on mine sounds like massive hassle, so if there is a way around the battery drain issue without upgrading the canbus that would be great.

If you search online for RNS-510 firmware, I'm sure you'll find many versions available. Josi is one of the RNS-510 gurus who has modified factory versions to be compatible with older radios and with the battery drain fix included (also VIM and secret menu  unlocked). It's not allowed to share in this forum the forums where you can get the firmwares.

Couple of people on here do a service for installing the software such as @Pashka (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=5723) and @Eddie-NL (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=2345) , I can do canbus change in about 10-15 minutes, although the first time it feels like an hour, but it's about as complicated as a radio swap.
Note the canbus in mine and the other car were both at the firewall the worst place lol

Yeah from what I've read mine is above the accelerator pedal and there's no way I'm getting to it with my shovel hands lol!
