Of course. It's a new battery, so I think it's okay. The workshop I decided (in the end) to not continue with discharged the battery as an additional "service". Jump started the car and got it home and this weekend I intended to to charge it.

Yes, the Audience sound system. This is also the reason I haven't got a Head Unit. I have tried to identify a seller that confirms that the Android unit works with av external amplifier. The unit I tried, did not work, even if I did the battery-trick. I only got sound in some speakers and lots of static. Any tips regarding units that work or resellers that have good price/performance and is can be trusted with questions/return policy, are greatly appreciated. I even looked up what it would cost to refurbish the unit I have, but the lowest price I got was 800€, with no guarantees of success. I can buy a old unit from junkyards for 350€, but that also feels quite expensive for legacy technology - even if I much prefer the analogue dials to digital soft buttons.

Hi, thanks for the tip, but I failed to include the information that I drove around with PIN screen on the Columbus for around a month, as the display was not responding. There was no change, before or after battery change.

Hi, Thanks for taking the time to read and answer. I had to wait for the new OBDII device. Battery had almost drained again the fault log is not useful, but I managed to get the version of the KESSY. System description: VWKESSYPQ35GP Software number: 5K0959434A Software version: 0802 Hardware number: 5K0959434A Hardware version: 085 Serial number: 0140690923 ODX name: EV_KESSY_PQ35GP ODX version: A01018 Long coding: 030C0C Seems it matches with your description.

Hi all, I've had some really strange behaviors that I'd like to have your advice on. It's s bit of a read because I'm not good at cars and it's hard to filter what is relevant. It's a Superb, 3.6l, 4x4 from 2011. First some history: 1. Three years ago, the trunk(!) started opening at engine start. It even opened by itself. Neighbour got in contact and told me I have had a car burglary. Turns out trunk had popped open and since I wasn't using the car for a couple of days, it was sitting open for a weekend. Had it in for repairs. Turns out rain water had leaked in through driver door window, corroding wiring in door. Replacement was around 1300 Euro. Painful to say the least, but at least things were back to normal. 2. Last year, my Columbus RNS541 display just died. Unfortunately battery died at the same time. I changed the AGM battery. I did no "battery parameterization" as I had no clue that you needed to do it. Things seemed to work fine, except the Columbus wanted a security code. As the display was dead, I couldn't really fix it Putting in a new Columbus was priced to 1500 Euro. Yeah, NO NO NO. I'm not paying that sum for ancient technology, I thought. 3. Summer -22. Did some research on retrofit Android units. Bought one that after a long email conversation where they guaranteed it would work in my particular variant. Yeah, NO. I have the amplifier under the seat, and I did the battery trick. But only the left side speakers started working. Even worse if I changed position in the driver seat the sound quality changed. Additionally, the seller tried to screw me and had sent an old model that didn't match the given specs. Alright I turned it and got a refund, but I DID NOT put in the old Columbus unit. I drove around without headunit for half a year. Idea was to get another Android unit, but life got in the way. 4. Noticed that the driver side capacitative handle intermittently did not work. 5. Winter -22. One of the first cold days. (-10). Drove to work without issues. When going home: + Cluster did not light up. Totally dead. + Engine didn't start + Lights inside car work. + Windows work and other electronics seemv to work. Disconnected battery. + Cluster starts up with lots of errors + Engine starts - ESP error, Adaptive lightning, Driver assist button error. On way home; key not found, steering column lock: workshop! - IGN off, IGN on did not work, battery disconnect, IGN on works. - Did E2E wheel turn and errors go away (specifically esp, adaptive, driver assist). Key not found did not reoccur. Steering column lock did not reoccur. Could drive 8-9km w/o issues. - IGN off. iGN on does not work. Battery disconnect. IGN on work. 6. I've done some obd logs, but either they're empty (except for issues due to missing HU) or really full of errors everywhere (after disconnect). I've ordered a odbeleven and hope to be able to take reasonable logs next week. Anyone have any ideas? Is it possible that it comes from missing headunit? Is it due to broken IGN button? (Apparently common failure) but would the cluster be dead then? Is it a continuation error from the KESSY problem? If anyone knows an Android unit that works with external amplifier (in a good way), i can spend money on that. It just feels strange that the HU would cause this. Can immobilizer+KESSY make cluster dead? Or is this a temperature + bad contact error? Where would this then be located? Ok sorry, for long post. I've read a bunch of stuff but i just have to face up to the fact that i don't have enough knowledge. I can't spend money on a new car right now, and i really don't want to either. I like my superb. I can replace the HU myself if I just need to have the name of a unit that works with external amplifier. I looked at YouTube videos for changing the IGN button/s.c lock but both seem complicated, but that's a limited cost. If it's the wiring I've understood it can be massively expensive. Cheers!

Sorry for the dirty state of things and the terrible exposure. This ECU was under the driver seat.

I read a bit on the forum to understand what you are asking. If I understood things correct, there are two versions. One with 8 speakers and one with 10? And the Columbus was delivered with both these configurations? And if you have the 10 speaker system there should be an amplifier under driver seat? Correct me if I misunderstood it. To tell you the truth, I don't remember what I bought back then. If I got it right, then I can check if I have anything that looks like an amp under the seat. Is there any other way identify the different versions?

Hi all, The Columbus unit of my trusty old superb died. The screen stopped working, other than that it seemed to still work. Tried resets add so on, but the screen is dead. A original replacement was terribly expensive here, so I opted for a cheaper solution and bought an aftermarket android unit for a fraction of the cost but on paper multiples better performance. Wasn't that difficult to install. And while more performant still crappy UI and integration. But well well... At first I had no sound at all. Not even noise on speakers. After disconnecting the battery for 30 minutes the left (driver side) speakers came to life, but after a number of firmware updates I still have no sound on the right side (front and rear). Does anyone here have any ideas what it could be? Does anyone know the wiring / fuses for a 2011 superb fitted with Columbus. It's a Conti unit. I can supply more information if there are variants that I don't know of. Any ideas would be appreciated. I don't think the speakers are dead or broken as they worked after the Columbus unit broke down. I triggered a call from the instrument cluster and the speakers worked fine. The mic did not. Different routing I assume. Hope anyone still bothers with these old versions. Thanks.
