Lots of great info, thanks guys! Actually, our Jeep came with two keys...
You're the first one I've heard that got a Chrysler with 2 keys that was NOT brand new on the Dealer Lot. Chrylser has made the key system so expensive and/or PIA to get spares, no one replaces a lost key, including the dealer trying to sell it.
The spare key issue is something you need to plan ahead about, like I said, Chyrsler saw too it, that only the Dealer can make the key and they are ripping off customers with outrageous prices for the spare keys. A little PIA work ahead of time, getting some replacement keys off e-bay will save you from the Dealer having you over a barrellel in the future if you loose your keys. Call around to your local dealers, in my case, some wouldn't do the starscan cloning of keys for less than $100, I found one that would do it for $50.
I read about the mercedes transmission thing, We bought this for my wife to drive so she'll probably take it to the dealership for service since I'm out of town a lot for business. I just found it a bit strange that ours is missing the cap too. Hoping it was carelessly left behind at the dealership. Additionally, they cant just order the cap, it has to be the entire dipstick assy
Something is NOT right here, because the DipStick Assy for the Mercedes W5A580 is a special tool that does NOT cap or fit the top of the tube, it can NOT be used like regular dipsticks that stay in the vehicle. The dipstick tool for the W5A580 will stick out of the end of the tube another foot and half, flopping around and NOT seal the top of the tube at all.
You want the plastic cap, if they are making you pay for it, you shouldn't be paying more than $3, sure some dealers that might mean $10. Don't let them charge you $85 for a plastic cap, because it comes with the special tool. If they do, then insist you recieve the special tool with the cap, and don't let them keep the dip stick for the service department.
Changing the Fluid, this one of the few things that can be done without the Dealer Starscan tool, it does need some special tools, the dip stick and an electronic scan tool for transmissions, so NOT all shops will be able to do it, but there are likely more than just the dealer. I'd comparison shop and make sure the Dealer doesn't rip you off. If the Dealer wants more than $100 to change the trans fluid and filter, he's overcharging. More than $150 would be outrageous and I'd go somewhere else and have them do it.
Don't let them flush the trans, tell them you just want the pan dropped and filter changed and refilled, that is what Chrysler Recommends, even though the Dealer will tell you otherwise, because they want you to pay tons of extra cash for procedures that Chrysler even recommends against you doing.
