Hans Posted October 26, 2019 Share Posted October 26, 2019 My first Chausson semi integral had a proper wiring diagram. Including the cable loops. And their location. On a Van they do not exist.Very difficult to lay a cable anyway. I can only comment when i see a proper diagram in A4 at least.OR double.Who wiil understand above comments anyway.

BrianK Posted October 28, 2019 Author Share Posted October 28, 2019 Keithl - 2019-10-26 10:12 AM BrianK - 2019-10-25 7:58 PM Keith / Alan, Thanks once again both of you for all the help. Keith, I’m assuming the BMS scanning needs to be conducted by the likes of a VW garage? Am I likely to still need this in your opinions? Brian Brian, Unless you have access to a scanner significantly more powerful than an OBD engine scanner then a dealer visit may be the only option. I have an Autel MD802 hand held scanner and this seems to imply it can access the 'Battery Regul,' module on VW's 'before 2014'. I have used it on many newer cars (including VW, BMW, Audi, etc.) but never on a T5. http://download1.auteltech.net/Download/Veh/ELITE/Enhanced/VW/en_MaxiDiag_E_VW%20FUNCLIST.pdf The MD802 has now been replaced by the newer MD808 or possibly better still the BlueTooth AP200 dongle. It may be worth trying one if you are prepared to make the investment. Keith. Edit: The MD808 seems to be able to adapt ECU's for fitment of a new battery... http://download1.auteltech.net/Download/Veh/MD808/BMS/Vw/en_BMS_Vw%20FUNCLIST.pdf and 'Before 2014' now becomes 'Before 2015' for 'Battery Regul'. Thanks once again for the input Keith Are you sure these work with VAG vehicles? Brian Link to comment Share on other sites More sharing options...

Brian The pdf I linked to says they do and I have used my MD802 on several relatively new VW cars over the last four or five years and it 'talked' to all I tried it on Whereabouts are you located? .If anywhere near NE Birmingham you're welcome to come and try mine.

BrianK Posted October 28, 2019 Author Share Posted October 28, 2019 Sorry Keith I should have pointed out I was looking at the AP200 not the one you have which I would fins very hard to justify for the use it would get. Do you think this is something an ordinary garage (not main dealer) could do and could you guess what they would charge. A what specifically am I looking to find out?!?!

Keithl Posted October 28, 2019 Share Posted October 28, 2019 If your local garage has something like a professional Snap On scanner they may be able to interrogate the BMS. The garage I use for my MOT's only has a very basic OBD code reader and call in a specialist mobile technician if they need any deeper diagnosis. Try phoning round and see if any can help, or try Googling for a VW specialist as they are more likely to have a suitable scanner. Keith. Link to comment Share on other sites More sharing options...

Hans Posted October 29, 2019 Share Posted October 29, 2019 Brian my dealer Vanomobil sells your Van type. Can you put in simple Words what your problem is. And Iam sure it can be solved before you leave. I like this kind of puzzles, to learn about it. My fuse box is easy to enter. But i have to take them out to see it has blown. Have always spares in all voltage whit me. And i will seek Advice from my super friend their. We will go to the end of it . Never give up. Link to comment Share on other sites More sharing options...

Keith, As I said previously I wasn't really up for investing in excess of 200 quid on a scanner I might not get much use out of, so was pleasantly surprised with the cost of the BlueTooth AP200. I also thought you might find what I have pasted below 'from Autel’ interesting, although I am still waiting for confirmation from them that this is the case with my specific van! Brian "Thanks for your inquiry. Autel AP200 diagnostic tool supports BMS function, which means you can use it to carry out battery adaption. For further confirming if this function will work on your car, please kindly provide us detailed car makes and year info, we will help you to check” "Compared with MD808 scanner, AP200 Scanner provides more powerful functions, such as full system OBD diagnosis and 19 special features including OLS/EPB/BMS/SAS/TPMS/DPF /Injector Coding and IMMO" Link to comment Share on other sites More sharing options...
Keithl Posted October 30, 2019 Share Posted October 30, 2019 Thanks for that info Brian, it is very much what I had expected. The AP200 is far more capable than the older MD series and has 2-way capability over the 1-way of the MD's. The only one BIG downside of the AP200 over the MD802/808 is vehicle applicability. The MD802/808 will work on pretty much ALL and any vehicle after 1996 (2004 for some Diesels) straight out of the box whereas the AP 200 requires software downloading relevant to your individual make of vehicle (eg VW in your case). This initial software download does not have an expiry date. If you want to use it on any other additional make of vehicle you have to pay for new software which then has a twelve month expiry. For one vehicle the AP200 Bluetooth dongle is the way to go IMO. Keith. Link to comment Share on other sites More sharing options...
BrianK Posted October 31, 2019 Author Share Posted October 31, 2019 Keith, Thanks so much for the continued help. I have had the answer I wanted and have ordered the AP200 now. One thing that's confusing me already from the instructions is whether you use the unit with the key switched on/off or engine running? The instructions say: 6. Turn the vehicle ignition to Key On, Engine Off position :-S ? The LED on the tool will light solid green when connected. Brian Link to comment Share on other sites More sharing options...
Keithl Posted October 31, 2019 Share Posted October 31, 2019 Brian, They mean Key On, Engine Off. ie not running. This is typically referred to as KOEO in the trade. If the engine was required to be running this would be KOER, Key On Engine Running. Make sure you select the correct software option for your 'Free' choice as you only get one attempt to pick correctly. Once you have connected via BlueTooth then you can start the engine to watch live data. Finally it is recommended to ONLY delete fault codes with the engine NOT running and after you have saved them for reference. Keith. Link to comment Share on other sites More sharing options...

BrianK Posted November 9, 2019 Author Share Posted November 9, 2019 Keithl - 2019-10-25 7:48 AM Can you get the vehicles Battery Management System (BMS) scanned for codes as this may give a clue as to why the charging voltage is remaining 'high'. For info I would expect to see the voltage drop to below 13 V every time you accelerate and only exceed 14 V when you decelerate (at least this is my experience form testing cars at work). Keith. Keith, Having got the AP200 and at last found some time to give it a try I'm after some more help :$ The attached came up as a fault when I scanned the battery regulation area. The summary page before this page says 02252 - Generator-No signal/Comunication. As I'm mostly staggering around in the dark here of course please say if there is a recommended way to look for what I want so far as the battery is concerned and of course anyone else who can chip in with any feedback too. Probably best to leave for another day (mentioning in case has a bearing on battery) but I also had 6 faults with the engine control module which I must admit is a little worrying! This is on the Can gateway Scan not the automatic choice from the menu. Brian Link to comment Share on other sites More sharing options...
Keithl Posted November 17, 2019 Share Posted November 17, 2019 Hi Brian and apologies for not replying sooner, I missed your last post :$ I'm not familiar with VW fault codes but 02252 definitely seems to be alternator related... https://www.google.co.uk/search?source=hp&ei=G4DRXeTZJKmUlwTVj5OwAQ&q=vw+fault+code+02252 All I can suggest here is possibly read some of the links in Google, eg the VW forums or possibly join a VW forum and ask the question. I'll try reading up a bit more and see what I can find. The bottom line appears to be that someone or something has messed up your smart alternator! Keith.

onecal Posted November 17, 2019 Share Posted November 17, 2019 VCDS Vag Com will do the trick,,, Perform an alternator test with VCDS if necessary you may need to replace the voltage regulator or alternator In the BEM (Battery Energy Managment) the following fault code may be displayed: 02254 - interface to the alternator. Check the wiring and connections between the alternator and BEM. It may be necessary to route an overlay harness for diagnosing. Repair any damaged wires and / or connections as required. If there are no fault codes in the BEM, but there are communication fault codes for the BEM in other control modules: Reset terminal 30 on the BEM (disrupt the power supply at terminal 30). If this does not resolve the complaint, replace the BEM. Link to comment Share on other sites More sharing options...
BrianK Posted November 17, 2019 Author Share Posted November 17, 2019 Keith & One Cal, Very many thanks. As i'm sure you can already tell I know nothing about vehicle diagnostics but as I have other faults as well (see pic below)and I’m wondering if there’s a chance they could be linked. I will take the advice and try the VW/vag specific websites but any suggestions/comments in the meantime would be appreciated. Another thing I’m wondering is if there is any chance the split charge relay (which I’m fairly sure doesn’t do anything) could;d be causing this/these faults. onecal - 2019-11-17 5:47 PM If there are no fault codes in the BEM, but there are communication fault codes for the BEM in other control modules: Reset terminal 30 on the BEM (disrupt the power supply at terminal 30).

onecal Posted November 18, 2019 Share Posted November 18, 2019 If you are not up to speed with using the VCDS then it may be prudent to bring it to a good tech' who is used to VW protocol if you fear your problem is VW related Link to comment Share on other sites More sharing options...

Keith. Thanks I think this must be worth at least a look. Would you happen to know if there is a way to clear all faults so as to ascertain if problems still exist? I seem to remember reading this could be done on the unit but all I can find in the manual is specifics such as how to clear all emission related data. Yes I hadn’t remembered that VCDS Vag Com was specific to VW but I obviously purchased the Autel MaxiAP AP200 to try and avoid such a high cost as I see the VCDS Vag start at about £500!

BrianK Posted November 20, 2019 Author Share Posted November 20, 2019 Unbelievably it looks like clearing the list of faults I had above has left me with no faults at all! This being the case I now have to now make a decision on how to proceed with the original issue/s Link to comment Share on other sites More sharing options...
