Stop vehicle shift to P message and what it means!

Hello!
If you see this message SHIFT TO P LEAVE ENGINE RUNNING you either need a battery replacement or you need yours charged when car is not in use.
Scanning with a Mercedes Benz scanner will show you the codes in the sam control unit. Also a battery test with a good digital tester .
I hope this helps!

THANKS LOU! Very informative- I'm dumping Mercedes-Benz for a new Tesla. No need to buy an expensive new DieHard battery (or three) every 2 years. I'd rather spend $10-15K on a custom replacement battery-pack just once in the life of the car. The peace of mind alone make this a sound financial transaction! See you at your next video!

Did not know that he wants to charge the battery with this message in the dash. Nice to know. With todays big electronics in the cars a good quality battery becomes more and more important. In my 2007 s-class i have the first battery in the front and the 2nd in the rear. I do not drive that often so i have connected a battery maintainer to it. I think that's why they last so long. And i choosed a Varta AGM for replacment like the original was before. Have a nice weekend Lou!

Very useful tip, as always Lou. Great job! Thanks a lot!

[@billmcquitty719]

Thanks Lou. A quick question. Do I need to provide electrical input to car so all systems stay active or can I assume the loss of electrical from battery is not important?

I'm old now! I had an Opel GT = used = back in the 1970s!. It was used! Great car! But! I had an battery problem! Either I'd have to get 1 special ordered from Germany or gang 2 12v together! Because it was so high compression and such a small starter motor! Next! It got extremely good gas mileage! But! It got almost impossible to find a gas station that sold " high octane gas like Ethanol or Hightest " and with each tank of gas = put it in and open hood & put tack meter on and adjust the carburetor! Ran Great! In the snow = it would crawl up and run on top of it!

Can I just charge the battery so no need for replacement?

[@mueckenhoeffer]

Nice to know. That must be a Benz/German unique thing, though I get some notifications on my newer domestic vehicles which surprise me. Have you done a video on the whole battery registration process I've heard is on some of these high end European models? You have to program the car's computer to accept the new battery? I'm scratching my head over that one.

[@MasterTechLou]

All the battery registers process entails is it learns the internal resistance of the new battery so it knows when its the battery is degrading by how much the resistance changes. At the moment im still catching up with that one after being gone from dealer for 10 years and now back. Not sure if its excessive resistance or too little resistance that sets the warning off. I think its less resistance, but ill do an update video on that one soon. Currently have a battery that made every one I talk to scratch their head. Wait till you see that one.

Why does my 2018 dodge Durango say that to shift to P but it doesn’t when I’m driving the car and it flashes the D on the handle and the flashes the den the dashboard I took it to dealership and they cannot find the problem. Can you please help me?

[@MasterTechLou]

Most likely a gear position issue or communications issue. Not sure why the dealer cant figure it out. If the fault is consistent then the diagnosis should be easy . Best of luck 🤞🏻

[@inanahmad7411]

Hi having this same issue now do I replace the main battery or the auxiliary battery ?

[@MasterTechLou]

Both depends on age. But that message is for the main. The aux will say aux.

[@ElizabethHernandez-oe4fb]

I’ve left mine running for 45 minutes and the message doesn’t go away 🙄

[@MasterTechLou]

@@ElizabethHernandez-oe4fb you will need a new battery

[@phinaboateng7308]

How long does it take to charge the battery

[@MasterTechLou]

There is no answer. It takes what it takes depending on how low it is and how many accessories you have on. Also if you use a battery charger it depends on the charger’s specs

[@ozziekls2271]

I have that message on my dash so when i change the battery do i need to coding? Also is that message will go a way after changed the battery? Do you know any thing about please?

[@MasterTechLou]

Message should go away once it’s replaced but you still need to have a scanner hooked up to reset the battery values in the “front sam” module

[@ozziekls2271]

Thank you so much for information 😊

[@Redskinno1]

Great video … does voltage reducer have anything to do with this issue and also my alternator charges 14.89 v .. is this considered over charging??? 2017 Benz GLC300 Thanks in advance

[@MasterTechLou]

Hi sir

[@BaljitSingh-dl1yw]

Sir I need suggestion mercedes Benz cla250 battery change after gear not working park stuck 051300 code fult pls

[@SGTECH-di9df]

@@BaljitSingh-dl1yw There is a Technical Service Bulletin for this concern [LI54.21-P-064054]. Either the transmission control unit requires a software update or replacement if the software does not fix the issue. After replacing any of the batteries in a Mercedes-Benz a "Battery Exchange" function through the scan tool must be performed. Hope this helps!

Thanks sir
