Hi Guys,

I got a message in the car cluster, i think its about the battry low.

Note that i notice that the ignation and the lights are working very well and that signal appear once i stop the car for more than 12 houres, once i swtich on the car and turn it off then swtiched agine it removed!.

May i know what dose that mean? Do i need to change the battery? note that two batteries in the car in trunk and under the hode which one must be replaced?

Thanks

Only a battery/electrical system load test can determine which if any of the electrical components in the vehicle's charging/battery systems is going bad if any.

I have gotten so many erroneous warnings in the MFD that I tend to ignore them if they don't stay in memory after restarting... but if they randomly appear 2 times or more I pay attention to see if its really an intermittant problem or just bad advice.

Best bet is to call roadside assistance and they will come to your home and replace the battery for free if you are under warranty.(If not you pay the price of the batter). I am guessing it is the battery under your hood that has gone bad since the trunk one is used for accessories and you get a message that says all accessories are temporarily disabled.

tariq,

If your car is still under warranty, bring it in. If not, you can test both batteries easily with a voltmeter. I just recently had the same problem but it was due to the aux battery dying, so I replaced it (64K miles on the car).

More importantly, just because that message comes up, it is not just the battery that's the problem -- it could be other components in the battery/alternator/BCU system that could be faulty.

Thanks guys,,

My car it not under waranty any more...

well that msg i got only once i park the car for more than 12 houres, once i swtich on the car it appear as shows on the photo above. but after two menits once i turn on the car and swtiched on agine it go!!!

Still dont know what is the mattar....

Any one forced the same before ?

This message signifies under voltage. I assume by your AUG02 join date and that you’re out of warranty you have a 03. At this point in time given it happens only after laying for 12 hours or more and quickly clears, as Paul mentioned, you should check both batteries for proper voltage and replace if needed.

Have you had these two Service Campaigns performed?

Service Campaign 2005070017 FEB06
Inspect alternator, replace regulator if necessary
E / SL (2002-2005)

Service Campaign 2005060008 JAN06

E (2003-2006) / CLS

Wrong!!! The trunk battery is the main one used for starting and the heavy loads. The under hood battery is the smaller one used for some electronics.

Tariq

Well the problem solved, i change both front and rear battery and now its great , after changing the battry make sure that the DAS system connect to install the lost data for some systems like brake ,,,etc

paulv

That's surprising that both batteries needed to be replaced. Or did you replace both because you wanted to?

sosh

There is certainly nothing wrong with being proactive and replacing both. The second one would have failed eventually.

Tariq

well note that the problem was from the rear battery, but its advised by the agent that if you want to chage that one you need to change the front as well, well technically i have no idea about the reason but its highly recomended to change both in case if you have problem with one of the two...

paulv

Sosh,

You're right -- there is nothing wrong with that -- I just would have tested the aux battery to see what condition it was in before making a decision to replace it -- my $0.02 worth.

...on the other hand, they're both the same age & have been used the same amount of time... I'd figure I'd rather tie the car up in the service department once instead of twice. Also, if they are both replaced it eliminates a possible witch hunt if the problem reoccurs down the road a bit.

paulv

Barry,

You stated another good point. I tend to test and analyze the hell out of everything before I make a decision.

Where did you change them Tariq,

I had the same problem, I changed the rear battery myself and then I took it to Sharjah Gargash to change the small front one. The battery is for 100$original but not from the dealer, the dealer charged me with fixing it 400$.

Tariq

Well you dont need to go to gargash, i dont trust this dealer at all..

go to workshop called Shtotgard in the industrial area where old location of Othman Garage...

Thanks man, I know this guy, but I didn't have a nice experience with him. I had a 600 coupe he kept for two month at the garage coz he couldn't figure out the problem and wanted me to pay 4000 $ US but I tow it to another workshop and fixed it for 150$ US.
