Dead battery issues

[IWMTom]

I'm wondering why most posts on this forum refer to the OBDII system as "OBD eleven". It is OBD two (II), the second version of the On-Board Diagnostic system. I have been on several automotive forums, and never seen it as eleven instead of two. Just curious.

They're not refering to OBD2.

Know it's a little late but... for anyone considering buying one of these LiPo battery jumpers, keep in mind LiPo are amongst if not the most volatile type of battery you can buy. When you're not using it, you should always keep it in a LiPo bag so if it explodes you aren't in the line of fire. Plenty of LiPo bags available on Amazon

dave: Hi. As a self confessed pedant for many years (perhaps a much bigger pedant than you?) - I really do understand your point. When I abbreviate "OBDeleven", I've tried to get into the habbit of using the short-hand "OBD11" (not OBDII). If this way of shortening the name is acceptable, I donate the suggestion to the forum (gratis)!!

I assume that (from a reply I got) that "OBDeleven" is a brand name of a device that attaches to the OBDII connector. I have a similar device, different brand.

I suspect it is someone originally reading/transcribing roman 2 "II" for eleven. Just like the EHI 01 helicopter, which became known as EH 101.

"the aircraft had been marketed under the designation EH101. The original designation was EHI 01, from the name given to the Anglo-Italian joint venture – European Helicopter Industries – but a transcription error changed this to EH101."

The problem is people read OBDII as eleven.

Comments welcome...

Last Friday I used my car, came home from work, locked it, it sat all Saturday, went to go out Sunday and found car wouldn't unlock. Popped the driver door handle cover off to expose the key hole and got in, key in ignition, and nothing coming alive. OK, dead battery??

I get my girlfriend's car in front, hook up the jumper cables, MFD and radio come alive with key in ignition. Start her car, go to start my car, and all I get is clicking noises. Then errors on the MFD screen : Tire pressure monitor system error, AFS lighting error, cruise control error, brake error... bunch of errors. Car won't start.

Use my free subscription to VW-connect to ask for tech help. They say that it's the immobilizer, and that if I didn't start the car within a certain amount of time from when I unlocked it, that I am locked out. Hmmm? They send a tow truck to bring to me a dealer.

Tow truck shows up, asks what the problem is. I tell him VW thinks its the immobilizer and I need to go to the dealership. He asks if the battery was dead, I tell him yes. He pulls this little unit out from his pocket, connects it to the battery, and jumps the car no problem. I'm baffled because 1) the booster battery is no bigger than my cell phone, and 2) why didn't the jump of the car work? He says new cars use too much power with the alarm, GPS, computers, etc and that if the other car was using the battery for it's own services, there wouldn't be enough power to jump my car. What??? Basically, I can't jump a modern car anymore. HUH?

Ok, whatever.... all week I'm thinking about this dead battery. The doors locked on Friday after work, so I didn't have a door open. No lights are set to be on in the car. No cell phone left plugged into 12V outlet... So what drained the power? No idea.

I plug in my OBDEleven and see I have a bunch of error codes for all modules in the car. I reset them all. All errors are gone.

Fast forward to end of the week. Come home Friday, park the car, lock it. On Saturday afternoon I go to start it, and get the same clicking sounds as before. This time no warning on the MFD, but all the idiot lights are flashing. Then on the radio I get a warning that the 12V battery is low and almost depleted. WTF? It's now hooked up to a battery charger. Charging at 12V 2.8A (1/10 the battery capacity of 280A --- why is this battery so small?), and battery voltage shows 11.73V.

I've had the car about 9 weeks, changes include a couple tweaks via OBDEleven (mirror dip in reverse, comfort open/close windows with remote, kencha tails, ignore bulb-out warning on license plate lights) and changed the glove box, backup, and license plate light bulbs for LEDs. I moved a fuse so the 12V outlet in the armrest is always active, but I didn't have anything plugged in except a USB adapter - it has a small LED on it. I also did leave my OBDEleven device plugged in, which emits a faint orange glow, so there is a small LED there. But I wouldn't think these two LEDs are draining the battery in 24 hours.

Nothing has changed in the last week to suggest why the battery is suddenly going dead. Annoyingly it only happens on weekends when the dealerships are closed. I called the local dealer about the last dead battery and he said he needs to diagnose the problem, and can't give a firm estimate on time, but I'd have to drop the car off and leave it. Hope this would be a warranty issue.

Has anyone else had similar problems, and what did you do to solve it?




TL;DR : 8-week old GTI, battery is going dead in 24-48 hours when car isn't being used. What to do?

So I just came across OBDII and have been considering a Vag COM cable for a while but the expense is astronomic (I could get it later but tbh, could do with it just now for various reasons).

Is it a suitable alternative to the Ross Tech cable people reference here a lot? I’m in the middle of checking an issue with my heater at the moment but my passenger mirror doesn’t dip in reverse correctly anymore and I’d rather spend the money on an OBD connector to investigate it than pay VW to use theirs!

Are you referring to OBD11?

 

[jimlloyd40]

OBDII and OBD11 look so much alike we should refer to them as OBD2 and OBD11. It's actually OBDeleven but people don't like typing that.

Yes to both, that’s the one.

OBD11 is easier and less expensive but I don't know if it has all of the capabilities of VCDS. But it should work fine for you.

So, that’s what I wanted to hear tbh! I have a Mac so the Ross Tech cable would come with additional expense to get it running with it (I need a VM running Windows 10 so there’s 2 additional software licenses needed).

My immediate need would be for diagnosing the heating system (I get no warm air from any outlet on my driver’s (RH) and my passenger door mirror; although it moves fully through the range-of-motion if I adjust it from inside the car, when placed in reverse the glass gets stuck on the way down, the way back up or it goes into the wrong position.

VW said it needs a scan.

Will OBD11 help me with that?

If all goes well, there’s an upgrade I want to do to the stereo to add Apple CarPlay which I found a guide for here. I believe some re-coding is needed for that - can OBD11 help with that too or do I need a Ross Tech cable for that?

You cannot add CarPlay with diagnostic equipment like OBD11 and VCDS.

Ok, ignore that part - I may be mistaken in what needs done with that and how. I know recoding is required, I probably made an incorrect assumption.

My main point is, OBD11 is a suitable alternative?
