CLK stuck in low gear
My CLK went into "limp home" mode a few days ago, right after going through an automatic car wash followed by a thorough hand-wash. It showed various alerts on the electronic display, including the "check engine" light. I was able to get it home by driving slowly (it would not go above 25 mph), and I let it sit without driving or starting it the rest of that day. The next day, after reading about this kind of thing online, I decided to disconnect the battery for 24 hours and then recharge and reconnect it. I also added some oil since I had gotten a couple of display alerts about low oil recently. But then when I started it up and took it for a quick test drive today, it still wouldn't shift out of low gear. The check-engine light is no longer illuminated, but now I'm getting alerts about the BAS and the ESP. Looking for any ideas about possible causes and solutions before I take it into the repair shop. I'd hate to spend a bunch of money on a costly repair, considering I was only planning to keep this car another 3-4 months before replacing it with something newer.
