Battery OEM Volkswagen or OEM Mercedes
When you say, \u201ctwo new batteries\u201d are you speaking of the big ones? There is a small one that operate your convenience/comfort items. It looks like a small garage door battery.
Tdi Touareg (mid 2000s) battery fits, with posts recessed and in the right place. Dealer price used to be like $115 and they are solid 900cca performers.
My original vw battery made it 8 years and 170k miles, but 10 years is pretty damn good!
Just got off the phone with my dealer to check, just in case they had a different update. Turns out my VIN has a recall on the battery. He stated as long as it's under 3 yr/36k it's eligible for replacement. Something to do with the connection was the reason for recall. Needless to say I have an appt. next week for a free battery replacement. My 2016 is at 2 yr/22k. I've had no issues myself other than the time it died while I was fiddling around in VCDS in the garage with the light switch in Auto (clearly my fault) :banghead: Thanks for the free battery replacement VW :thumbup:
Took my car to the dealership last week for warranty work on a leaking water pump and they told me that there was a recall on my battery. Battery was replaced the same day, had no prior notice of the recall before the visit.
I've got a '13 R with KESSY and NAV. that had a weird slow start, which made me think the KESSY swt. was worn like another thread mentioned. So I tore it apart and it was dirty on the contacts so I cleaned them. After that it seemed better but the car had 30+K miles and I did get another weird slow start, so I tested the battery and it tested good/charge. I did end up replacing the battery. I haven't had any issues since then. Now at 52K miles.
Since the battery weighs ~40 lbs this isn't really a significant weight change from front to rear so I've no idea if the car handles any differently. Would I recommend this mod? Probably not as it's not cheap and has no real performance advantage and more crazy than anything.
I installed a new battery but now the car won't start or turn over.
The batteries Mercedes uses seem to be really poor quality. I have a daily class and it seems they are changing the battery every 1.5 years so far on average…
I've dealt with this issue on both of my newer AMG vehicles. My older ones never had this problem. From my understanding, this is caused by the new mbux system being a bit of a power hog. I eventually had to invest in a trickle charger, and I have to charge both of my AMGs 3-4 times per year. It gets worse as your battery gets toward the end of its lifespan.
