paul_james09 Posted September 16, 2023 Share Posted September 16, 2023 Hello, friday morning I has these errors all come on at the same time whilst starting up. I just wanted to check if they're all likely to be related to each other/a fault with the ABS sensor? Ive seen a few posts about the ABS and stop start being related but i dont see how the headlight range control could be? It looks like a pretty cheap/easy part to replace if thats what is causing the issues. Or is there anything else i should check first? Many thanks in advance Quote Link to comment Share on other sites More sharing options...
Magnet Posted September 16, 2023 Share Posted September 16, 2023 Hello Paul, I think you will find that such issues could be linked to an inefficient battery, so my first port of call would be to eliminate or confirm that possibility. I would take the car for a 15 to 20 mile run, then get the battery efficiency check - Halfords can do this. Buying a necessary replacement from Halfords- ? Perhaps you could let us know how you get on. Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
paul_james09 Posted September 16, 2023 Author Share Posted September 16, 2023 I’d hope not it’s only a year old and supplied by my local Audi specialist. But thanks Ill do that first thing in the morning Quote Link to comment Share on other sites More sharing options...
Magnet Posted September 17, 2023 Share Posted September 17, 2023 Thanks Paul, Even if it does turn out to be sub-standard, then it should be under warranty. If it’s serviceable then obviously you have at least eliminated it. What make is the battery by the way? Worth getting Halfords to do an alternator test at the same time. Kind regards, Gareth.

Magnet Posted September 17, 2023 Share Posted September 17, 2023 Can’t/ don’t want to download your link. Alternator output checked? I wouldn’t have thought an ABS fault would knock off the Stop/start, but I guess stranger bits of Audi logic have occurred. Your car is probably too old to have the additional ‘small battery’ as well as the main battery -? Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
cliffcoggin Posted September 17, 2023 Share Posted September 17, 2023 When a series of apparently unrelated electrical faults appear simultaneously my first suspect is always the battery. It does not matter if the static voltage is fine, it does not matter if the starter can crank the engine over normally, it can still have a fault that interferes with the car's electronics. Sorry, but too I will not download links from unknown sources. Can you attach the file to a reply? 1 Quote Link to comment Share on other sites More sharing options...
paul_james09 Posted September 17, 2023 Author Share Posted September 17, 2023 It was just a photo of the battery. Looks like like the terminals have crusted over a bit. Alternator seems to be fine. I’ll get it to my local mechanic in the new few days IMG_5356.dng Quote Link to comment Share on other sites More sharing options...
paul_james09 Posted September 18, 2023 Author Share Posted September 18, 2023 Here’s a list of trouble codes I’d that helps 03841 - RPM Sensor Rear Left: Incorrect Signal. 00290 - ABS Wheel Speed Sensor Rear Left (G46) 01316 - ABS Control Module below is directly copied from carista. After googling some of these seem to be displaying incorrectly I believe… CAN network gateway: 01304 - Radio ABS: 00290 - Left rear ABS wheel speed sensor 03841 - Hybrid/high-voltage battery group 2: Performance Power steering: 01316 - Engine Oil Pressure Too Low Steering wheel: 01304 - Radio Telephone: 01304 - Radio 02503 - Output wire to radio Headlight aiming: 01316 - Engine Oil Pressure Too Low Heater & air conditionina 01592 - Throttle Actuator control (bank1) Range/Performance Quote Link to comment Share on other sites More sharing options...
Azharul Posted September 18, 2023 Share Posted September 18, 2023 Hi, I am having the same issues as well on my Audi A6, incorrect fault codes have been coming up. I assume it will be the battery as I am getting mine changed on Wednesday Quote Link to comment Share on other sites More sharing options...
Magnet Posted September 18, 2023 Share Posted September 18, 2023 Hello Azharul, I wouldn’t assume anything. You could find it isn’t the battery after you have unnecessarily spent money. I would simply get it tested and depend on the result to inform you it is/isn’t serviceable. Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
Magnet Posted September 18, 2023 Share Posted September 18, 2023 Heel Paul, ‘Alternator seems to be fine’. Have you actually had its output checked? Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
Azharul Posted September 18, 2023 Share Posted September 18, 2023 Hello Mganet, I got my battery tested yesterday RAC they said it serviceable/rechargeable, the Votage it is currently at is 12.47. They said this is too low. They tested the alternator out as well, reported back saying all is fine with the alternator. Quote Link to comment Share on other sites More sharing options...

paul_james09 Posted September 23, 2023 Author Share Posted September 23, 2023 Battery voltage is 12.6v with engine off and 14.2 with engine on. No blown fuses either. It'll be in the garage Thursday so we’ll find out what’s the crack Quote Link to comment Share on other sites More sharing options...
paul_james09 Posted October 2, 2023 Author Share Posted October 2, 2023 Been in to the garage and all these faults were caused by a faulty ABS sensor at the rear it was given false readings compared to the rest Quote Link to comment Share on other sites More sharing options...
cliffcoggin Posted October 2, 2023 Share Posted October 2, 2023 Thanks for letting us know. It just goes to show you can not take all your error codes at face value. Quote Link to comment Share on other sites More sharing options...
