I have a 2012 and I'm going to sell it buying another Honda pilot

@@coreyknox3969lol I have both a gl550 and a Honda Pilot. Run from both of those cars.

I believe all cars have the ability to be hit or miss with reliability. However, the gamble is greater with German cars. I had an 03 bmw 325 that over the course of 5 years of ownership I spent around $2k on maintenance and repairs. On the other hand, an 07 mini cooper S I bought just last year, I have spent more money in maintenance and repairs than I paid for it a year ago.

Compressor replacement

Mercedes has made MILLIONS in profit because they put the battery where it is.

From my experience, issues with the auxiliary battery normally show up as issues with locking and unlocking and the alarm. If you aren't having issues with that, I wouldn't worry about it

where u can find the second aux battery ??

My 2015 GL450 said on instrument panel that Aux Battery is Low. Changed it after message appeared a second time. Located in the back right side of trunk.

Thermostat change

Its possible but very difficult my wife has gl450 . Took awhile getting the battery out

Battery is charged by the alternator during normal driving. If the battery is going dead after a few days, even tho you are driving it regularly, it would most likely have a failing alternator. This usually will cause a battery light to come on while driving. However, if it has a large battery draw and you have a short commute, it would not be enough time for the alternator to restore what is being used while it is sitting.

Napa battery should be okay. Haven't ever really noticed any difference between them.

Did you find out if the battery needs to be programmed? After replacing it ?

The only way to move the seat if the battery is completely dead would be to connect jumper cables from another vehicle to the jump point in the engine bay. I have never encountered a vehicle needing the key reprogrammed after the battery dies.

Hmm, that's an interesting one. I've never heard of that one. Would likely be a transmission fault with that warning. Could've done something weird when reconnecting the battery. Would definitely have it looked at.

​@@MunkysGarageif i replace battery and my gl doesn't start and show a.lot of errors and my gl doesn't start anymore best thinh that i can do

2008

How much was the battery?

Which programming are you worried about losing? And I don't know if there is a way to get the auxiliary battery out without taking the main battery out.

@@MunkysGarage my small aux battery is in the back the main is under the passenger seat.

@@michelnadon6243 Hmm that is interesting. I have only seen them in front of the main battery. Maybe different years or models they moved them around.

I'm getting a big red battery signal on my dash board of my 2007 mercedes gl450. Help please.

You can replace the battery without needing a computer.

Yes, it should be the same procedure.

Hopefully not to late of a reply to help. What do you mean by deprogrammed?

I have only ever had to replace that auxiliary battery on mercedes in my career. It was having issues where intermittently it wouldn't unlock with the remote. Turns out the auxiliary battery supplied power to the alarm module when the rest of the vehicle was asleep. I wouldn't worry about it if you aren't having any other issues other than it needing jump started.

@@MunkysGarage thank you so much for your timely and knowledgeable response. I enjoy your channel

Received it cut like that. But my mini has them too, and they are useless.

Eh its not so bad. I've had cars where you have to cut the dash frame to remove the cabin filter. Engineering at its finest

Thas proof that a mechanic or tech was banging engineers wife and that's whis way getting back at all mechanics n techs

Agree with you that the battery should be someplace easier to reach. Most German cars put them in tough to reach areas. One of the upsides of putting them inside the vehicle is they are less prone to the temperature swings of the outside of the vehicle and the batteries tend to last longer. I've replaced a battery in a BMW that was 11 years old when it finally gave out. You won't normally see that life out of one placed in the engine compartment.

Also on the slow reacting starter, I had the same issue with this vehicle. Thought it was just battery or cable issues. It had the issue for about 5 years, then the starter went out. After replacing the starter that issue was no longer present. Just something to think about.

@@MunkysGarage thanks for the reply. We just got home from the Mercedes-Benz repair shop. They said the starter wasn't the issue, it was the 10 year old original batteries. Found it it has a main battery and an auxiliary battery!!! I have no clue where that 2nd battery is! I hope they're right that it was just the old batteries..

It amazes me that people actually take time out of their day to be rude to others.

It also amazes me that anyone will watch a video with no audio explanation. Your’s is a very informative vid and I appreciate you replying to all of the comments.
