Hi guys so I'm new to this website and I'm new to the whole Mercedes world so forgive me in adavance . So I bought a very used 02 c320 with 160k miles (don't even ask ) And to top it off I'm on un employment and spent the last of my money I had been saving to buy some sort of reliable transportation and i totally got ripped off by a private seller. Anyways back to the point .. I bought the car less then 6 months ago and first thing the cluster light started to fade out .. u can still see it but barely .. then about 3 months later I started having battery issues I would jump start it every morning and then after about 3 days I call AAA they test the battery and it's dead .. I made it to Walmart got a new battery ... now 3 weeks later my battery starts to die again .. I jump start it every morning just like before but I noticed this time when I would go to manually unlock my trunk (because that's where the cables were) my key was turning but having a seriously hard time doing so and even then the latch wasn't unlocking .. I also had 2 faulty codes come up on the dash and one I believe was DTR ? And the other had something to do with stability control and tires not going at the same speed or something ? That might be the same thing as DTR I don't know .. oh and then it said something about a front left light but I checked the lights in the front and they were all fine .. so after 4 days of jump starting I went to do it the next morning and nothing ! Car was completely died it would turn over but absolutely nothing not even a crank or anything the lights would come back on but that was it . I call AAA and they come and check the battery and not only is the battery completely deAd ( mind u this was was brand new and only 3 weeeks old and it's already dead ... so the AAA guy is taking it out to replace it with his and he is ttaking it out He notices that not only is it not the right battery they Had Installed a battery that was too strong for my vehicle and it was leaking battery acid Walmart left this little plastic tube Attached to my battery and that is where the battery acid was leaking from. But here's where the real problem comes into play as AAA installs the brand new battery the right one the right size my car still doesn't start doesn't crank nothing just completely dead. I am beyond stressed Out I live in Mission Viejo and I'm in Lake Mathews visiting a friend and it's time for me to leave and I cannot leave because I cannot start my car I'm trying to do everything I can to figure out what is draining my battery so quickly and so heavily. Another thing that I forgot to mention and I don't know if this could be the possible reason it my battery is draining is that I think that there is a quarter stuck in the driveshaft I know this sounds crazy but at when I had taken apart the ashtray a quarter had fallen down there and I totally forgot to take it out and then I Put the ashtray back without taking out the quarter and now I noticed when I go to put my car in park it feels like it doesn't go completely into park because when I take The key out of the ignition And I shut the door and I see the cluster light on the dashboard is still on . so I don't know if that could be draining my battery but it does go into park at least enough where The P for park lights up when I put it in park but also when I take the key out I can move it from Park almost to reverse but it doesn't switch gears but it's loose . So I guess what I'm trying to say is it's not latched in the park I can still move it . I don't know if it's always been able to do that because like I said I just got the car but if someone can let me know if when they put their car in the park Position does it normally lock N position or can you move it from the park position to the right Well the key is out of the ignition. Sorry this is so long and it probably is so confusing I'm just trying to give as much information as I can because I need help or any advice I can get from anybody that knows anything about Mercedes because I know absolutely nothing and I'm stuck 50 miles away from home and I just need to do what I can to fix his car so I can get home . I already had AAA tow it to a shop and they wanted 280 just to diagnose it I spent $80 just telling it there because AAA only covered 7 miles but I can afford 280 to have them just tell me what was wrong with it they won't even take a look at it so I had to get it back to where I am now and I am trying to diagnose it on my own which I'm sure you guys were thinking is crazy by the way I'm talking because I have no idea what I'm saying but I honestly do you know somewhat what I'm doing so if anybody can just give me an idea of what they think it might be or what I can try to look for a check or whateverI have all the tools I have the time and I just need advice because I don't know what I'm doing so anybody that's willing to help me out I will love you for the rest of my life please somebody read this and help me. Oh and I swear this is the last thing I'm gonna say ..I don't know if this makes a difference or not but my key fob is like dead basically I check the battery and the battery was dead almost dead at least could that have anything to do with it?
