Upgrading 2nd generation radios (RCD 300, RCD 500) to 3rd generation (RCD 210, RCD 310, RNS 310, RCD 510) power drain issue

Early build Volkswagen cars can experience a power drain issue after upgrading their 2nd generation headunit from a RCD 300 or RCD 500 to a 3rd generation headunit like the RCD 210, RCD 310, RNS 310 and RCD 510.

The problem is the CAN bus Gateway is too old and an updated version 1k0907530 (1k0 907 530) of L revision or higher is required – CAN bus gateway removing, installing and upgrading – Volkswagen Golf.

in vehicles belonging to the model series PQ35/PQ46 from
model year 2008 as well as the Tiguan,

Vehicles belonging to the model series PQ35/PQ46 from model year 2008 (MY08) as well as the Tiguan have gateways that are updated. Earlier models may require the updated CAN bus gateway to be installed. See Volkswagen Model Year Information for more details on the week of manufacture however generally Volkswagen change over Model Years around Week 22.

This problem does not* affect retrofits of the RNS 510 which is a 3rd generation head unit as this unit was in the production in 2007 whereas the RCD 210, RCD 310, RNS 310 and RCD 510 are recent additions.

Check the ‘Skoda Parts’ link (right hand menu) for a reasonably priced gateway. Revisions that will work after the 1K0 907 530 S (1K0907530S) revision include 1K0 907 530 AA (1K0907530AA), 1K0 907 530 AB (1K0907530AB) and 1K0 907 530 AC (1K0907530AC).

* This problem does now affect the RNS 510 if the firmware is upgraded to 2660 or higher. The RNS 510 will exhibit the same problems as the RCD 210, RCD 310, RNS 310 and RCD 510 and requires the CAN bus gateway to be upgraded.

  8. hi all, ive gathered that a new can bus is the fix to this problem, but was wondering if there is any adaptors on the market to fix this issue like a anti battery drain or something also can you upgrade the firmware on the rns 510 c version to bypass this problem and what is the latest firmware that can be installed on it, is it possiblle to update the can bus via vagacom to the 0178 software for the module or does it have to be changed physically end of story ?

  10. Hi

    I have few questions. My car is 2005 VW Passat 3C. I think i have old CAN bus gateway, and my radio is RC D300. I have now bought an RCD 510 radio and i was wondering two options. Does same firmware versions work ro RCD 510 and RNS 510? Beaucose i haven’t found any firmwares directly to RCD510. And what would be the right firmware version for my radio so i don’t have to change my CAN bus gateway and still have no battery drain issues? If i end up changing my CAN bus gateway, what are the codes for suitable gateways that i have to search?

  19. Hy there, i have an golf 5 1k from 08.2005 and i want to replace my rcd300mp3 with an rns510. is it possible? I have read this forum a lot, what things should i know before doing this, do I need an other CAN gateway or not?

  20. Hi can enybody help me Iv got a 08 plate Jetta with a normal radio but want to up grade to a gps one but it looks like it’s came with a cambus and don’t no were it goes does this have to be fitted or is it optional and were is it fitted as there no wire for it on the loom that came with radio thanks

  21. I just installed an aftermarket unit on my Jetta 2007 MK5. Its got bluetooth, GPS, DVD, iPod, USB, MIcroSD and A/V Inputs. It’s a very fine unit and sounds great. At first I got the infamous battery drain issue and was told that a canbus gateway upgrade was the way to fix the problem. After looking at the wiring schematics for the unit however I noticed that the harness have two 12V power leads, one for always on feed (yellow cable) and one for switched feed (red cable). So I ran an additional cable and installed a fuse tap on an available switched slot on my fuse box. I then cut the red cable on the harness (the one that came with my unit, NOT the factory one). That lead is marked ACC+ in my case, but test before cutting though. Finally after connecting the red wire to the new line, the problem was fixed. No need to change my canbus gateway. Everything works fine, no messages on my screen, wheel controls work fine and no battery drain issue.

    1. disregard. Missed it being an aftermarket unit. Though I had this same issue with a porsche. So im thinking of applying this fix to the RNS 510 and seeing if it does the trick.

  22. I have had this issue when I bought an RCD310 for my 07 plate Passat. But are you saying the RNS510 would work and NOT drain the battery. I really need to upgrade as my rcd300 doesn’t play mp3s

  23. wonder if someone could clarify something for me, does this battery drain issue only occur when upgrading to a 3rd generation VW headunit ? or can it happen with any new replacement headunit ? I currently have a 2005 Golf Plus that I want to install a new Sony head unit in and don’t know if this will cause the battery drain issue everyone keeps mentioning ? thanks

  24. I’ve a December 2008 Golf 2.0 TDi and have removed the RCD300 and fitted an aftermarket PURE DAB radio. My CAN BUS is IKO 907 530L and yet I still have battery drain after one day? What am I doing wrong? I thought my Can Bus was ‘new’ enough to be Ok? Thanks
