INSANE Battery Drain (VW Touareg TDI - Part 2)

Now that we have diagnosed the INSANE PARASITIC DRAW on this 2012 VW Touareg, we have to REPAIR the issue! Some parts will be required.
After installing and Coding the replacement Passenger Door Module (PDM), I try out a neat 2-channel portable oscilloscope to verify the repair.
This Crazy Euro Case Study definitely did not disappoint :)

Great job Ivan finding the problem but the curious part of me wanted to see if the door module coding change fixed the mirror functionality. I really wanted to see the mirrors fixed too. Almost a cliff hanger!

[@larrybe2900]

Since the problem began after the damaged mirror it probably still won't work BUT the damaged mirror might play havoc on the replacement module. Perhaps repairing or replacing the mirror could be the ultimate repair.

[@ecaparts]

I was wondering that also. The 'new" module was showing no DTCs but the mirror movement wasnt commanded. Would have been interesting to see what would happen during the special function test mode...

[@michaelgleason4791]

Coding in VWs (and Audis etc by extension) is pretty amazing. You want to install some heated mirrors? If you install the OEM stuff you don't need a new module. Just change the coding, and the car knows. Want to use a module from a car with different options? Also no problem, just change the coding to match your old module.

[@05c50]

Another great job Ivan. I was hoping that you would open up the module (I'll be that you did) so we could see if this was another module taken out by water intrusion.

[@Beni_777]

Hi Ivan! At the coding part, each octet or slot you were referring are actually just hexadecimal numbers for the binary digits, what you can edit. Each "slot" in the long code has 1 byte of space, that is 1111111 in binary or FF in hexadecimal. You can set each extra-option like heated mirrors and such with a single bit like 0 or 1, then it's convereted to a hexadecimal number, to fill the slot/ocetet in the long code. In this case it was 01011110 to 5E. Good video as always!

[@thephantom1492]

I will also add that for binary to hex, split it in 2 groups of 4 bits. 01011110 = 0101 1110 Now, each position is worth: 8 4 2 1, so you have 4 and 1, that make 5 And 8 4 2 = 14, for 10-15 you use letters, A B C D E F... 14 would therefore be E Which make 5E

[@leonardodavinci303]

Typically, each byte is 8 bits . you used 7 in the first example and 8 in the second. I know....but being a good programmer, or auto diagnostician, you have to be a bit obsessive compulsive OC.

[@dogsplantscarsneatstuff176]

Ivan I would like to make a request. You are a busy guy so this may be a bit much to ask. Would you consider doing a video on the Pico 4 channel (or some alternatives like you showed here) and the accessories that you find most useful. This could include the physical items you use with your scope as well as the best wiring diagrams be it Alldata or Mitchell. Many of us could save our cars from the junk yard as you do. Some people say a $4K scope is way over the small garage mechanic or the home mechanic. I would say if I can save a $40K to $70K car or truck from having to be purchased I have done my job. Also since many mechanics are parts changers some people could leverage this to a part time job. I am in Calif. so having my car towed to your house might be a tad pricey. Besides we have Gavin Newsom and he fixes everything. Thanks for your time.

[@renefuller9241]

Those Number are hex numbers (Base 16). Long coding lets you turn on and off different options. Some of those might not be installed, but you'll find out when you play with it. Do record everything though. One possibility mentioned in another comment is that the module was coded wrong which made the module behave erratically (not going to sleep). Definitely play with it, but maybe on a Golf, or other model with modules that are more accessible. We have a 2017 Golf. I read up on it and got myself an ODBCII reader to play with it. And being in IT helps a lot. Love your channel! I learn a lot; it's fascinating what electronics can do with cars. (Or cars can do with Electronics) 😊 Btw, did you ever find out what the "aftermarket" wiring was for?

Just got my scope, neat little thing. 1 small issue to report that might help folks. I turned it on when i got it and it seemed to work just fine but the batt indicator said low batt. Next day I turned it on, plugged in the cable to charge it and the battery must have been too weak to power the device and it sorta crashed. I could see a (very faint) big battery sign on the screen with a thin red line showing it was low, but there was no response from any buttons, even a long or super long press of the power button. I took out the 4 screws on the back and unplugged the battery and it is now working just fine. I know nothing about scopes, thats why I bought this lil fella, cheap education :)

Pico and probably others have a decoder for Can and probably more that may be able to get the address of the module(s) talking on the network. Not a typical DIYer tool but if you know who is who on the network you get the address and the data being sent. The cat man was looking into it.

[@volvo09]

@@volvo09 Pico website says included in ver 6 and 7 maybe more.

[@n124lp]

I don't think knowing the ID of the module that is sending a particular network packet would help in a 1-off diagnosis like this one. After decoding the ID (priority), you would still have to figure out which device uses that ID. It's not like a home computer network, where each device has known MAC and IP addresses that you can look up in the device configuration. I do think that feature could be very useful when diagnosing more complex CAN problems or building / modifying CAN-enabled devices.

[@GarnConstructionInc]

@@n124lp The id’s “addresses” are usually not published by the mfg but there is some info online. “OG” has a GM database started that was very detailed but may not be allowed on KZbin. I found a VW site also. One rule of thumb was that the lower the ID the higher the priority on the can bus.

The long code is the same for all cars it is actually referred to as variant config. Basically if you on a can bus request to read a data identifier e.g A1. A1 on Holdens are the variant configs for the module the Module will respond with what it has in that memory location 2E,7F,5A,4R. Changing 7F to 3E will enable tpms or 2E to AA will enable hsv mode (NOT ACCURATE HEX VALUE FOR HOLDEN JUST EXAMPLE)

The reason to put more modules into a car is that customer is forced to go back to the dealer network for diagnosis. You are lucky that you can replace the module.

That is very common in Europe, but I know is is coming to US also (Cadillac I think).
