my battery die last night bc I left the lights on. I got a jump and the car started up. However it had the "red battery visit workshop" message. I drove the car home with no issues. This morning I started the car and the red message. Poped up on the display. So I got my multimeter to charging voltage and it was 11.97v so I wait a few mins and it droped to 11.90. I drove the car around for 20min hoping it will charge. However when I check again it was at 11.69. I remember with my other cars it was like 14v when the charging.

Any one else knows what's up?

 

replace the battery?

 

Shouldn't it come up, perhaps 13.7 V even if the battery was bad, when the engine is running? Could be the alternator, the charge regulator?

 

I'm going to take the battery to an auto parts store to test the battery to see if its jack up.

 

I'm on my 4th battery, all warranty.

 

Well i could the battery to autozone and after 45 mins of testing the battery showed good. but for a piece of mind I bought a duralast battery. however i get the same red visit workshop. however I get a extra message it displays " battery protection convn functions are disable. I'm going to take the car first time in the morning to the dealer with out appointment.

 

If I remember correctly there was a TSB in regards to the voltage regulator on that MY E. HTH

 

I hope there is and I hope the dealer won't screw be to hard....

 

I believe that at the time I found out about it it was a freebie. Too lazy to STFF. But I do remember posts about it on here. HTH

 

Service Campaign 2005070017 APR06 Inspect alternator, replace regulator; The VIN range as it pertains to your vehicle (211.083) is X108399 – X178599. The alternator regulator fails to prevent voltage values ranging beyond the specified tolerance limits. As a result, the battery may be insufficiently recharged and the convenience systems may be shut off due to a resulting under voltage condition. All 113 (i.e.: e500, e55, and e500 4matic) engines are equipped with Bosch alternators and require regulator replacement. Note: unlike DTBs, Service Campaigns do not expire.

 

Thanx for jumping in and posting the details konigstiger.

 

once again you have all the answers... I dropping car off early in the morning. Hopefully they won't be to mad that I dont have an appointment.

 

Oh by the way my vin is with in that ranger. . which I'm at it I'm going for the windshield wiper nut covers that you mention a while back.

 

well the dealer changed the voltage regulator. so the problem with the alternator. since my car is out to factory warranty i told the SA to call my aftermarket warranty company. I guess this is a good time to see how well continental warranty works..
