I took it in to the dealership for an inspection before purchase and I mentioned that the A&amp;#x2F;C wasn’t working before inspection. They charged me what you’d expect (plus extra to diagnose _just_ the A&amp;#x2F;C) but gave the car a completely clean bill of health aside from the A&amp;#x2F;C, which they attributed to a bad blower motor.&lt;p&gt;I asked the seller to have that fixed before sale, and they took it to another shop who replaced the blower…and still nothing. That shop kept the car for 2 more weeks and came up with nothing for answers. They took it to another BMW dealership who inspected it for another week and came up with nothing.&lt;p&gt;So I turned to Google. Found a likely problem, but needed BMW dealership to confirm with proprietary tools. The BMW dealership had &lt;i&gt;no idea&lt;/i&gt; what I was talking about. I had to literally tell them “can you plug in the foo widget and go to the bar screen and check the baz value shown there? Now can you hit Reset in the corner?” Magically, the A&amp;#x2F;C started working.&lt;p&gt;I’m not sure how “right to repair” plays into my story. My real point is that technicians are human and imperfect; troubleshooting is hard. It’s not necessarily a conspiracy that they make mistakes, nor is it personal that they believe the diagnostic data in front of them over some random person _convinced_ it’s a specific problem—even when it seems completely obvious once the problem is fixed.</text><parent_chain></parent_chain></comment><story><title>Sometimes it is just a bad battery</title><url>https://rachelbythebay.com/w/2021/08/19/batt/</url></story>

Sometimes when I gave it the beans it would pop up a flurry of scary error messages about the engine, that I had to take it to the mechanic to have it checked out and so on.&lt;p&gt;500 € later and the mechanic could not fix the issue.&lt;p&gt;Other times, just turning on the engine it would complain that some filter was almost full. And once, on a longer than usual trip, it gave up on me in a pretty steep incline and I had to stop on the side of the road, let it cool down a while, and turn it on again and it worked mostly fine if I didn&amp;#x27;t accelerate too much.&lt;p&gt;Then a few weeks ago it did not start at all. So I measured the battery and it turned out it was toast. I had a friend bring me to buy a new one and swapped it in.&lt;p&gt;The car started fine. But incredibly, it never again displayed any error messages and seems to be completely fixed!&lt;p&gt;Not really phone related, but yeah, sometimes it can be (surprisingly) just the battery...</text><parent_chain></parent_chain></comment><story><title>Sometimes it is just a bad battery</title><url>https://rachelbythebay.com/w/2021/08/19/batt/</url></story>
