as i thought <MB are usually very competitive battery wise and on tyres too
Deffo Oe is the right choice
No coding required, level sensors are quite cheap also, Febi do them,
Think mb number A2115427717
Yep, I think you are right.
Does anyone know if the new level sensor needs to be coded or anything like that? I’m going to refit the original otherwise as I don’t understand why an intermittent dash warning has progressed to a permanent one if the new sensor is correct/working.
Is there a date stamp on the terminal as well ?I confirmed the battery is indeed from 2011. I made it out as 18-04-11 on the label but it was mega-faint, I had to tear it off and pass it through light to make it out. The extensive history does however show a battery fitted at the dealer in May-11, so it ties up.
I know someone else mentioned it, but I’ve only just looked properly. It’s stamped 0411, so likely April 2011, or could be the forth week of 2011 if they do it like tyres. Either way, triple confirmation that its a 2011 battery.Is there a date stamp on the terminal as well ?
error in serial communication to rear lamps and interior motion sensor. No response from component N70/2b1 (interior protection sensor) - The interior motion sensor is also listed as 'not activated.'
Thanks that is very useful information. I though I read that the alarm siren had been replaced on mine, but checking back, I have no record of it - I'll pull off the arch liner and check the date on it at the weekend. I remember AMGmeister did the siren on his car - I may go back and rewatch that video.I had this fault on my S211, and mine was parasitically draining the battery every 48 hours - would be down to 10v after this length of time.
Root cause was the alarm siren located within the inner front wing, driver's side, behind the plastic wheel arch liner. It has a rechargeable battery that is long since toast at c. 13 years old. Because the car is constantly trying (and failing) to charge that battery, it keeps the CAN network awake and drains the battery.
I posted about it here, perhaps it helps.
These cars throw up lots of spurious errors when the batteries are weak, mainly because (I think) the battery voltage drops so low after cranking that the sensor readings go outside of programmed tolerances. I would solve the parasitic drain (assuming yours has one too), and fit a new battery first.
Martin.
2004 S211 E55 AMGB33 is in rear cargo are, right side under trims.
B31 is engine bay, under windshield depending on engine (you have not specified on avatar more car info) which side. Use google search, might find it, difficult to explain without picture
Thanks for that. I must have missed post #8.Like said #8, passenger side mirror WONT dim in any Mercedes.
Acceleration sensor fault will put aimatic to 'limp' mode where it is at hardest set, or sometimes even drives all struts to upper end position.
Check rear sam for water damages, some of the faults are driven by rear sam.
