A leaky thermostat housing is a common issue on Mini Coopers of that era. When mine began dripping in December, the first thing I did was check the do-it-yourself repair videos on YouTube to see if this was a job that fell within my decent repair skill set and one that I had the proper tools to carry out. The part could be purchased for as little as $34 on eBay. But the thermostat housing is buried in the engine bay, requiring the removal of many components, several of which have multiple electrical connections. That combined with cold weather — I have an unheated garage — convinced me to let the Mini dealer tackle this one. Even though the total bill was $620, there was good value there, and I was happy with the service and price. Let me explain.
To get a taxi ride home from the dealership and back again (I don't use Uber or Lyft) would have cost about $50. The dealer's shuttle saved me from spending that. The new, genuine BMW thermostat housing has a 2-year/unlimited-mileage warranty. If it breaks, BMW replaces it and covers the entire repair. If an aftermarket thermostat housing fails within a year, you might be able to return it for a replacement, but you'll pay again for the labor to install it. Finally, as with many dealers, my Mini store treated my car to a free full inspection.
The dealer uses the Hunter Quick Check system, so as the car was driven into the bay, the alignment and tire depth were checked. It was disappointing to learn that three of the four new Michelin tires I had installed in 2018 were wearing out after just 16,000 miles. I never would have thought of checking the tread so soon after installing new tires, but after this winter, they'll be replaced.
Since I bought the car used, I had concerns about the health of the battery, but it checked out. So did all the other fluids and, of course, the brakes. That inspection added value to the repair. So did a coupon for $50 off an oil service, another job I am loath to do in the driveway during a Detroit winter. Even though I could have done the thermostat housing job myself or paid an independent garage to do it for less, this experience shows how the dollar figure on the repair order doesn't always tell the whole story.
