Hi wipe the codes and see what re emerges, the dates look pretty old or is that a quirk of your computer, sometimes the modules become clogged with redundant info and need clearing but if you clear all codes only the ones that are relevant should reappear, the headlight range module is a bit strange as I am assuming your model will have levelling sensors on the front and rear.
Steve.
I individually cleared the fault codes from modules 01 (Engine) and 61 (Battery Regulation). I started the car (started smoothly without any hesitation) and let the engine idle for about 45 minutes and then ran an auto scan. I did not get any fault codes in any of the modules. I had noticed however that in Advanced Measuring Values Group 010 for Battery Regulation module 61, the Generator Interface was oscillating between OK and Not OK continuously. The battery state of charge showed 100% so the battery did get fully charged by the new alternator. The engine speed in the Engine module values was 640 so the sensor should be working. Looked at other measured values in the Engine module and they seem alright.
After stopping the engine, I restarted the engine after a few minutes. There was a slight hesitancy (cranking) but the engine started. I do not know however, if after driving the car and parking if I will have the crank-no-start issue again.
Thanks again and best regards.

Hi I don't know what the exchange rate is but you might be better off sourcing a replacement on eBay as I am sure it won't come to that!, I get my alternators done locally and a refurb with a three year guarantee is only about £350, do some research and find out if there is anyone that does reconditioning in your neck of the woods.
Steve.
Hi Steve
Thanks again. I followed your advice, got a remanufactured alternator shipped from the US and had it installed at an alternator workshop. Drove it home - everything looked OK. Next day I left for a long holiday and returned yesterday.
Went grocery shopping this morning and car started (cold engine?) without any problem. To return, the car only cranked and would not start. I had to wait quite some time (engine cooled down?) before the car would start.
On reaching home, suspecting starter or relay, I took a scan. Found several DTCs in the engine module showing no communication intermittently between it and other modules including the battery regulation module. That module itself had intermittent "No communication with Diagnostic Interface for Data Bus (J533)".
I also lost the Date/Time.
Best regards
Dawood

Hi Dawood I really think that changing the alternator would be best policy as they will have to check its charging correctly and if its not they will have to find out why, but I honestly think its the internal voltage regulator thats gone bad especially in view of its age.
Steve.
Hi Steve
When I went to collect the car, the auto electrician said that he really did check the continuity of the wire from the alternator. He mentioned that the output voltage was lower initially but increased later. I do not know if he did it back probe style. Looking around for alternator shops that can do the job. The closest in my area quoted $ 250 labour, $ 45 for coolant and $ 650 for refurbished alternator or $ 1500 for a new alternator. I know the voltage regulator can be replaced but I do not know if the guys here do it.
Thanks a lot again Steve for all your advice.
Best regards
Dawood

Hi let me know what you come up with, and if possible check the alternator output at the plug, back probe style.

Hi Steve
I was away outside the country in April/May and nowhere near my car. Returned 10 days ago. As the Q7 alternator is way down on the right in the engine bay, obviously I could not reach the connector by myself. I got an appointment with an auto electric shop for last Saturday, provided them written details along with the log showing that the Generator Interface shows Not OK at specified alternator voltage 14.5 volts and it becomes OK when specified alternator voltage is 14.6 volts or greater (does not show > 15 volts). I asked them to check the blue wire on both sides for continuity and check the output voltage using back probe.
He said they would do their own scan and charge me $ 160 for the scan. After a week he says I should replace the alternator which as it involves mechanical work, they would not do. I doubt he has checked the blue wire at all. I now have to collect the car today, pay him $ 160 and wonder if I replace the alternator at an alternator shop even though VCDS shows the alternator as OK.
Have a good weekend.

how old is the alternator as it can only realistically be that or the smart charge wiring, 13.5 volts is a good average and is this problem throwing a light up.
The alternator is as old as the car - 2007. There is no alternator/battery warning light showing on the dash. The two times it showed up was when I had the incompatible energy management module on and the car stopped on the road while idling. The battery voltage then was 11.2 volts.
4 hours ago, Stevey Y said:check the voltage from the alternator should be 14-14.5v on a multimeter
After I installed the compatible module, the voltage measured at the battery boost posts under the hood showed 14.0 volts constantly but with the DTCs 02254 (Interface to Generator 004 - No Signal/Communication) and 03041 (Energy Management Active 000). The earlier DTC with the incompatible module 02479 (Partial Consumer Shut-Off Active 000) has disappeared. The voltage goes down from 12.4 volts while cranking before it stabilizes to 14.0 volts.
4 hours ago, Stevey Y said:check the plug wring from the alternator for corrosion I have known it to be corroded under the insulation and the wire is brown and not copper coloured which causes a resistance especially on the pulse wire to the ECU, there is also a situation where the regulator in the alternator is going up the wall and sends a voltage spike
I will check the alternator plug wiring for corrosion and the voltage regulator for spikes. On the VCDS graph, the alternator specified voltage is a straight line while the battery actual voltage varies 0.1 volt.
Thank you again Steve and best regards

Hi what leads you to the conclusion that your alternator is not charging, the whole point of smart charging is that the alternator steps up the voltage when the battery is becoming drained to compensate for the loss of voltage, therefore it would be cheaper to buy an upgrade alternator rather than blow the electrics by feeding in power to a 60amp socket instead of out.
Steve.
Hi Steve
Nice to receive your response again.
Its a continuation from your responses to my earlier post of "Recommendation for AGM battery for Audi Q7 2007 4.2L FSI". I received the compatible Battery Mangement Module and installed it. It got registered but the DTC 02254 (Generator Interface not communicating/Not OK) is still generated when starting the car. After some time the Generator Interface shows OK and I am positive the battery is charging as the actual voltage is then 14 volts or more. When the Generator Interface is Not OK the voltage is about 13.5 volts and I am not sure the alternator is charging the battery adequately. In case of an extended idling situation I am worried the battery will run down if in a Generator Not OK state. Hence I was investigating the situation where I could manually insert the trickle charge (using CTEK) if that would not introduce excessive current.
At start, the alternator should be able to get 12 volts from the battery via the battery management module to create the magnetic field to start turning. Does the DTC 02254 imply that there is no continuity initially between the alternator and the connector on the battery management module. I would have to verify this continuity with a multimeter, Hence my other post "Continuity of wire from alternator to J644 in Q7" to figure out how I will go about doing it.
Thank you and best regards
-
In Audi 2007 Q7 4.2L there is a single wire from the alternator to the energy management control module J644. I have been asked to check for its continuity as part of diagnosing Generator to Interface fault (02254) when I start the car.
On the J644 side the end would be in the connector (pin 8?). Where would the wire be on the alternator side? Would there be an intermediate point too near the J644 module under the driver seat where I could check the continuity using a multimeter with the pin in the J644 connector?
-
Can car battery while engine is running be charged by a smart trickle charger powered by a portable power station if the alternator is not adequately charging the battery at lower RPMs?
The trickle charger would be charging via the cigarette lighter socket in the car during excessive idling periods in traffic.

Thanks again Steve. He has asked for VIN to check compatibility. Hope it will materalize.

The part arrived. I will replace on the weekend. Elsaweb says I need to re-encode the module after replacement. Is it necessary? VCDS does not allow coding for the energy management module. It only allows coding of battery.
Thanks and best regards.

Thanks again Steve. I had put this query on the North American forums without any response.
The new one from Audi is quite expensive. There is an eBay seller located in St. Albans UK who sells refurbished ones with three years warranty and seems to be reliable based on the feedback. Listed on 20 Oct 2022 with the generic part number 4L0 915 181. If in stock, I am asking for faster delivery. Hope he responds today.

Thanks again Steve. Again very informative. I will make it a point to read your responses on the forum whenever I am free. That should improve my knowledge of these cars.
Any idea why the status (OK or Not OK) of the Generator Interface between the alternator and the battery management module is dependent on the alternator voltage (Generator Voltage being 15 volts or 14.5 volts respectively)?
Best regards

Thanks Steve (Stevey Y) for a very informative response. I registered to this forum today as I see while browsing that in the UK and the European continent you people have much more experience with German vehicles than here in North America.
The Audi dealers here try to sell AGM batteries when one goes to them for a battery purchase. They charge nearly twice the other shops do.
Temperatures here are quite low in the winter. When I look at Measuring Blocks using VCDS (Ross Tech) for Battery Regulation 61, I find that Group 001 Generator (Alternator) Voltage Specified does go to 15 volts. In fact the Output Tests in the module 61 work only for Generator Specified Voltage of 15 volts and not for the other choices of 13.5 volts and 0 volts. Generator Voltage Specified is also measured in Group 010. When the Group 001 Generator Voltage is !5 Volts then Group 010 Generator Voltage is also 15 Volts.
However when the Group 001 voltage is lower such as 14.5 volts immediately after starting the car then Group 010 Generator Voltage is 0 volts and the Generator Interface to the module 61 is lost (Not OK). The Generator is OK as shown in Group 010 whether the voltage is 14.5 or higher. When the Generator Interface is not OK I get the DTC 02254.
In time the Group 001 Generator Voltage rises to 15 volts, the Generator Interface becomes OK and Group 010 Generator Voltage also shows 15 volts.
My mechanic says the alternator and battery are both fine. However some time ago he had replaced the Battery Management Module J644 with one for A6 C6 as the Q7 version was not available. I was wondering if an AGM battery with specs 110AH, 950 CCA and 1000 CA would rectify the problem.
Sorry for the long post.

Thanks Gareth.
Always used the regular lead acid battery. Want to switch to AGM as they are supposed to be longer lasting especially considering the difficulty of replacing under the driver seat by myself.
As for availability - Varta with Audi dealer but no local retailer for Bosch. We get Energizer, Exide and Interstate among others. More availability in the US.
Have a good week and best regards.

Thanks Steve. Will get one for Q7 and replace. Have a good day!

Looking to purchase AGM battery for Audi Q7 2007 4.2L FSI. Any recommendations?

I have two cars – an Audi A6 C6 2005 V6 3.2L and a Q7 2007 V8 4.2L.
Quite some time ago, my mechanic had replaced the battery management module in the Q7 with an additional one that I had lying around for the A6. Is the A6 module compatible for the Q7. The part number for the A6 is 4F0 915 181A/0 199 000 013 while the one originally in the Q7 was 4L0 915 181/0 199 000 017.
I am asking the question about compatibility because lately I am having a problem in the Q7. Whenever I start the Q7 engine, the battery management module gets the DTCs 02254 – “Interface to Generator 004 - No Signal/Communication” and 02479 – “Partial Consumer Shut-Off Active 000”.
Previously in the autumn of 2022, the Q7 had stopped twice while driving. As I could not immediately restart the car, while waiting, I had measured the battery voltage and found it to be around 11.2 volts. The DTCs would appear then. I had to wait for the voltage to rise above 12.5 volts before the car would start. I assumed therefore the battery was weak. I do not want to replace until I am sure that its not the battery management module nor the alternator. What causes this temporary loss of interface to the generator? Bad alternator? Weak battery? Connection problem between alternator and J644? Or the J644 module itself? I measured actual voltages with multimeter and they seem ok except when the car had stopped and the voltage was 11.2 volts but that has not happened again.
In attempting to analyze the reason for the DTCs, I used VCDS Advanced Measuring Values for Battery Regulation 61 and noticed that whenever Generator Interface was Not OK then the Generator Voltage was 14.5 volts and when the Generator Voltage would rise higher that 14.5 volts e.g. 14.7 or 15.0, the Generator Interface became OK. Additionally, I tried to find out from Ross Tech Forums for VCDS where the Generator Voltages (Group 1 and Group 10) are measured to understand why both are not the same. No success from there. Obviously, they are measured at differed points for their values to be different.
