Hi folks

Installed a new battery into our 2010 A5 2.0TDI Cabriolet, and started up VCDS to update the details of the new battery. However VCDS is reporting "no response from controller". This is the 61 Battery Regulator controller. No error lights on the dash or anything, I would have expected the battery light to be lit if there was a problem with the charging circuit.

There were a lot of historical low-voltage errors which I cleared (due I guess to the old battery which didn't hold a charge well). However controller 61 still not responding.

Any ideas ? VCDS problem or car problem ?

Thanks
Frank

obviously, you don't have module 61.
my A5 does not have one either.

from the Ross-Tech manual: (http://www.ross-tech.com/vcds/tour/main_screen.html)

On some new vehicles like the 8T0 (Audi B8 platform), the Gateway Installation is not accessible via Long Coding. In such cases, use the [Installation List] button in the Open Controller screen for CAN Gateway to access this screen. This function is available in all Gateways that support an Installation list and is explained on the Installation List Page.

Long Coding. This function is needed to Code some control modules in the newest cars which use CAN for diagnostics. Due to the complexity of Long Coding strings (up to 255 bytes of hexadecimal data) we've accommodated (and urge) the use of Copy & Paste in this function and usage of the Long Coding Helper.

Here is the link to the control modules present / available to VCDS in the A5/S5... no #61.

Ross-Tech: VAG-COM: Audi A5/S5 Applications

I'd suspect you are in good shape as-is if everything works, you can do an autoscan and look for any codes if you like. Battery voltage can be checked through several (maybe all) of the controllers. Should be readily available in 01 engine for example. If the car doesn't have a separate battery reg module, there isn't any coding needed as i understand.

Thanks lads. There is a black box on the boot floor just beside the battery, but I haven't had a close look to see what it is yet. I always presumed it was the battery controller.

I cleared some historical low-voltage codes from VCDS (the car had a history of flat battery) and it all seems nice and happy with its new battery.

However there are two codes popping up that refuse to go away, see below. Nothing apparent on the dash, no warning lights or anything. I would at least have expected the red battery light to be glowing, but no.

Here's the report from the CAN gateway - what do you make of this ?

Seems the CAN gateway isn't hearing from the battery circuit (J367) or the voltage reg. Apparently if the car doesn't have a separate CAN module (#61) then the CAN Gateway itself reads the battery data directly from the J367 box. I suspect this is the box near the battery that you are seeing. You can take a look and see if any of the connections were disturbed or not re-connected in that area when the battery was replaced.

Also, you can check the following: {if they work}
19-CAN gateway > Measuring Blocks > Groups 18,19 and 20
and compare to the battery percentage shown by MMI {if equipped}

and:
19-CAN Gateway _> Long Adaptation -> Channel 4 -> Battery identification

This is where you could re-code for the new battery. Not always required, but it might help to solve this issue.

Hi there,

I had this issue apparently for years without knowing until I did a VCDS report.
Both Battery and Voltage Regulator Modules unreachable.

This must be a flaw in the A5 (or more) and likely a bad join on B698.
I solved it today by placing a correcting wire. See my article and resolution below.


Side effect was that start/stop wasn't working. The car had no idea about the battery load.

Working now perfect again.

This is really helpful thank you.

Hi ssmith,

You can sign-up for free and browse through Google translate to the pages.
It contains explenation of the issue, documents and photo's.

I solved it today and all errors are gone.
Now battery on display also indicates the correct value instead of 100%

Regards,
Ferry

Hi.
sorry for my English. It is talked more than once here (about 00458 and 03705). I found where the mistake was! There is a clutch in the wiring harness in the right rear corner of the vehicle where oxidation acts!!!
