How Audi A4 Battery Replacement And Coding

Car model: Audi A4

 

Symptom: left my car in covered storage for 3 months, was in a rush and forgot to disconnect the battery before flying home. The car was running perfectly fine before leaving, when I got back, the battery was completely dead. It took two jumper boxes (battery and under the hood) to get the car running. Now, I need to jump it every time I drive.

 

Solution:

Option 1: Called Audi to inquire about replacing the battery, they quoted me a ridiculous $600 (apparently it takes them 2.5 hours of labor to replace and code a battery).

 

Option 2: AutoZone charges $150, but can’t code it. Sears said they could replace and “register” the battery for $280.

 

Option 3: I ditched my OEM (Varta) battery a month ago, installed an Odyssey PC-1350 and never looked back.
You can run different batteries in these vehicles. Don’t let the dealers b/s you.
If you really need to code the battery buy a foxwell NT530 scanner. Bang for the buck you can’t beat it for $200. It does battery coding, channel adaptation (used it for green menu access), and rear brake caliper functions (for pad changes)
As a mechanic, i have VCDS, a Snap-On Zeus, and the foxwell scanner. I wear the heck out of the foxwell scanner. It’s just cheap, and it works great.
My only caveat, some of the letters on the screen are a bit tiny. Hitting middle age, and going blind…. Ha!

 

Option 4:

Replaced my battery in my 2014 b8.5 last night. Had a 15% off coupon for battery and installation from the Audi dealer so I got the battery for $180 and I took it home and popped it in. Wasn’t sure I was gonna code it but it was actually really simple.

 

Everything you need is on the battery it’s self. The the part number is on the top and the serial number is visible if you use your smartphone camera to look at the square qr code on the back. I did the coding in my obdeleven app with my smart phone. I have yet to find a single think that my obdeleven can’t do compared to vag-com.

How to Solve 04 Toyota 4Runner 4.7l alternator issues?

Car model and year: 04 Toyota 4Runner 4.7l

 

Issue: have alternator issues

 

Details:

I went on a business trip for a week, got back home went to crank it and the famous click click click. Battery was under warranty took it to napa they tested it said it was just low they charged it and i brought it back installed and got her running. Here is where I think I have a problem, I let it run for about 15 minutes to warm up it was rather warm here in South Carolina over the weekend. I had to go to my shed and get something so I turned it off. when I returned I cranked it back up and now when it cranks if the tack gets below 1000 rpms the engine shuts off. After a couple of times of doing this not wanting to kill the battery it still does this when cranking and giving it gas, it will run but when I take my foot off the pedal it dies.

 

Optional method:

Option 1:

I’d start with Foxwell BT715 battery analyzer from:

http://www.foxwelltool.com/wholesale/foxwell-bt715-battery-analyzer.html

 

Foxwell BT715 will tell you that the alternator is “good” (or bad) and what the charging rate is, as well as if the battery is “good” (or bad).

 

Option 2:

If you can get the truck to most any auto part store they can test it for you for free. That way you don’t have to buy that tool unless you want to. Just get it started, and drive over to a store, keep it running and they should be able to do a load test on the battery and charging system. Its not 100 percent accurate but its pretty good.

 

Operability:

For the option 2 method, it was my first thought but when I go to put it into gear it shuts off…..

 

Option 3:

Use a meter… measure at battery while engine idles, you should have ~ 14VDC. If only 12VDC or lower, the alternator is not working properly.

 

Option 4:

I’m guessing it could possibly be something going on with the throttle body, in older models vehicles the TPS…Throttle Position Sensor is a separate/replaceable part attached to the throttle body and if bad can do what your’s is doing plus other issues, but on the 4th Gens 4Runners the TPS is integrated into the throttle body and can’t be replaced.

I have never had to test one but you can Google search “Symptoms of a Bad or Failing Throttle Position Sensor” , which may help you get started on how to test the sensor to see if it’s bad, you may have to do more research to be able to actually test it properly, such as the values mentioned to know if it’s within the correct range and the type of sensor it is.

 

Option 5:

I suspect a bad battery coupled with bad NAPA testing, it is possible. I have had batteries heat up and the plates touch. So If possible check voltage, find a ground inside the car, ground one side of the meter and CAREFULLY test the cigarette lighter voltage, I believe it is straight battery juice. Be careful not to short out the probe, protect it with tape if you have to.

 

Please try any of the above methods according to your actual situation.

 

Good luck!
