EB Boch now called Nucar is were I get all my oem parts from also. I'm in CT and I can say that the hard shift with high idle is always present 1st thing on a cold morning. Never a issue in the warmer months.
In the last couple of weeks, I have done the following to my '15 LC with 200k miles.
- Replaced the original water pump! (finally gave out at 200,885 miles)
- Alternator (bc I was in there and had the radiator removed)
- Fan clutch, pulley, and...
Not sure I have more to add as I posted a bunch on the other thread.
Short version. I had the leak, it would be random, I tried new foam, weather stripping, a “hood”. None of it worked until I just replaced the cowl. I’m due another windshield...
