Battery for Audi A6 2006

[NickPicks]

Also I went to KwikFit to get a quote on battery replacement. They ran some test and said I need both battery and alternator replaced and will cost me £800!!!. I will go to another place and get a second opinion. But do you know if there is any way for me to tell if there is an alternator problem? I don't have any problems with the car which make me feel I need to replace alternator.

Go somewhere else and get a FIRST opinion, and resolve never to go anywhere near kwik fit ever again.

Hi Guys - just called Battery Megastore and they says that size 020 will not fit in my car as it is 393 mm in length. Their database only shows 315 as the maximum length for Audi A6 2006 Diesel 2.0. Can someone confirm the battery size for my car? Currently I have 017 size in there, but it might not be the right one. Also I cant find 110Ah in 017 size.

Just checked the battery in my car and see that there is gap for a larger battery to be installed. The currently installed battery is around 350mm. So 4 cm will not be a problem. Finally ordered this one.

Gupsterg - do I need to buy the plug which you mentioned below? or it comes with the battery? Also the vent tube is currently hanging out in my car. Wasn't sure where it needs to be connected. Will make sure I connect it correctly with the new battery.

Do connect the vent tube (item 3) and block one side off with cap (item 2) Link:- http://www.jimellisaudiparts.com/sho...String=battery.

Got the battery and installed it today. Didn't use any backup battery. So lost the time and trip counter. Rest all seems to be working fine. Thanks every one for helping out.

If your esp light is on you can fix it by doing a full lock to lock on the steering and go a short drive and it will clear.

You'll also have to re-do the one-touch on the windows but that's a 30 second job.

Hi Chris - Thanks for the info. I had to deal with ESP light coming on before, when I had to do jump starts. It went off by itself. So not worried that much. I checked all the windows but I have convenience open already enabled even after the battery change, just like before.

I have noticed one problem though which I didn't have before. When I put my keys in the ignition, I hear a quick cracking sound through the speakers, before the audio start. This wasn't there before the battery swap. Once the audio is running, I don't hear any strange noises.

I have again checked all the voltages with voltmeter while engine is off and running (with air con, lights, radio on). I see around 1V difference in the readings. According to some information I went through, if there is more than 0.5V increase, then the alternator is working fine. Not sure if this is the right way to check an issue with the Alternator, but for now, I am not going to bother about it. I will get a fault code check when I have a chance.

Yep, just sit back and enjoy the car. Clear all faults and then scan when you have the time.
