Hi

I posted this also on the SL55 AMG forum...

I am getting an error Electrical Consumers Offline causing most functions to cease working (including roof operation) for about 15 minutes every time I start my SL55 AMG. I have only had the car for 2 weeks and this problem started this week. This is a 2002 car. Has anyone experienced this? Seems the second battery is not charging enough or perhaps it is analternator problem. Please let me know if you have seen this and what the soltuion turned out to be.

Thanks in advance

I've seen this before. I think the solution was to take it to the dealership and have them fix it. It happened on my friend's SL55.

According to WIS, when the battery control unit detects low voltage, it goes to STAGE 1 SHUTOFF. All basic electrical consumers are turned off to save power automatically. Your heated seats should also stop working. When the dealer hooks the star daig system to your car, it will show the mechanic what the exact problem is. Could be a low battery, bad battery control module or other device sucking too much power.

First answer is, of course, to go back to the dealer and tell them to fix it without you having to worry about it. Get it logged in as a service visit so you can start the Lemon Law counter ticking.

Read once somebody had a problem where their Comand unit kept spinning the Nav disk after they turned off their engine. Screen was blank, but disk was still spinning. But I am not sure that burns enough watts to drain the battery in one night.

How much time passes between when you shut off the car and when you come back to find this condition?

Do you have a cell phone plugged in over night?

Any type of antitheft devices like LoJack? They have their own small battery, but they tap into your car's battery to get a charge.

How far is/has the car been driven on a daily basis? A friend only lived 5 miles from his business and all his cars have/had battery going low problems. MB told him he did not drive it far enough to recharge sufficiently.

Thanks for the replies... I use the car twice a day... half an hour drive each time... perhaps that is not long enought but even if I restart the car after few minutes, there is no charge and the car takes another 15 minutes to charge... should not be the case? Kind of makes having a convertable pointless if you can not open the roof vertually everytime you drive! I am scheduled to take it in in a couple of days; will let you know what they say.

Turns out a cable that controls the lock on the glove compartment was leaking power causing a drain on the battery. A new cable and a new battery later and it seems the problem is solved.

Wow, would never have suspected that. Leaking?
