But, in bringing my ride in for its A service at 100K mile tuneup, they quoted me $352 to change sparkplugs. Yes, friggin plugs, 6 of them, for $350. So, unless the dealer is beyond a complete racket, and into criminally insane territory, there has to be something more to changing these out, right? Or is this the price of a 3 pointed star on your hood? I'd guess pop the plastic tupperware engine topper, disconnect the battery, unplug the plug wires and have a go at the plugs, 3 per bank. Dunno the torque to use, maybe the parts guy at the counter would offer?

Also, dealer gave $149 for the engine intake filters. WTF?

Anyway, next up is a check engine light the ***** threw about a month or month and a half ago. I figured it was a thermostat by the way the temp gauge got nervous in the days afterwards. Luckily, it was February in Jersey so little chance of any damage. But now with the weather increasing...... Dealer confirmed it was a thermostat when I brought it in but won't tell me the OBD code. Not sure if Mercedes parses out their codes well enough to tell the location if I could get the code? Anyway, does anyone know where the thermostats are on these things. I reckon like most others there'd be one at the radiator and one at the engine block? But, I've never wrenched on German cars before. Only Swedish, Jap and Amerikan cars. Any tricks to a mercedes thermostat?

much thanks for any help

Any luck on this topic? I also saw someone asking about replacing the down facing courtesy lights on the side mirrors. Ultimately this is my goal.

Thank you in advance!

From the inside to outside, run a cable tie into the channel. Tape wire to the cable tie, and pull it back through. Replace the side-view mirror cover.


Unplug the (6) connector and lift the clip to slide off the connector lock.


Use a small flathead to push these pins in and back, so you can solder into the wire connector.


Tin the ends of the connector wires and the connectors using a very small amount of solder.


Hold the ends together and apply heat from the soldering iron to solder wire onto connector.


Push the pins forward again, and slide the connector lock back on.

Run it in reverse to reassemble.


I fail, someone tell me how to resize images in the post.
