€4000 euros plus tax to replace the module that contains the fuse. Insane.

The ford transit custom PHEV costs £4500 to replace the timing belt. Access issues mean dropping the hybrid battery and parts of the sub frame. Compare with the mk8 transit, i've done the wet belt myself on that and it requires no special tools (well, i bought a specific crank pulley puller for £20) and can be done in a day on the driveway. I believe in some markets the replacement schedule is down to 6 years for the new phev due to all the wet belt failures on older models.

So far my favourite brand to work on has been Mazda, the engineering is very thoughtfully done with consideration for repairs.

I hear a lot of praise for toyota but it's from people who haven't worked on a car themselves rather than mechanics and they must be talking about toyotas from a bygone era because i'm not impressed with a 2019 corolla engineering at all, specifically various parts of the electrical system. I believe that was the most popular car in the world at that time.

Tesla is remarkably well done. Simplicity is under rated. So much so i bought one with the intention to keep for a looooong time.

Is it insane? I'm working in this field, and I know how quickly you can come up with such a number if you are BMW and you are deathly afraid that someone will get electrocuted while working on your car, driving it or rescuing someone in a crash. It's a safety and liability issue, where they go to great lengths to actually re-certify a battery after crash. The whole thing is setup so, that even the dummy electricians in an average BMW shop can safely certify that this battery is still safe. It's a lot easier to kill yourself (or someone else) when working on a EV Battery than wet belt. Also a lot harder to repair said battery than wet belt. And that goes for all EVs and manufacturers that actually care about people (Tesla, demonstrably does not).

Yes, it is insane. It's a fuse. They must have some stats on how often those things need replacing and it should have been accessible. The customer has - when they buy the car - absolutely no way of knowing what kind of surprises like this there are hidden in the vehicle and besides, it kills the second hand market so you can only trade your vehicle to a BMW dealership where they can absorb those costs for a fraction of what it will cost an end user. BMW is a crap brand in spite of their reputation, we've had one leased Mini in our company and it is the very last time we do business with BMW, that thing was more in the shop than out of it with electrical issues. A friend had pretty much every BMW ever made since he got wealthy enough to afford them (car enthusiast) and his experience is much the same, but he keeps buying them.

Fuses are not items that should be replaced normally - they are self-destroying emergency protections for the electrical system.

If it is protecting that end users can plug arbitrary loads into, that is one thing - but this doesn’t sound like that?

Why did that fuse blow? Because if that is not addressed, it’s likely to just blow again.

Yep, might be there was a known issue that was addressed, at which put in a new one. But just replacing a fuse (or, simultaneously worse and better, just resetting a breaker) without further investigation is just kicking a very spicy can down the road.

I had a doozy of a trip issue on one project, a motor would occasionally (not always, no real pattern, hot/cold/etc. didn’t matter) trip the breaker, requiring a sparky to come out and open up the panel to reset it. We tried a bunch of things, megger-ing the motor, testing peak startup current on each phase with a fancy meter, checking phase-to-neutral current (Larger than you’d think! But this was normal, apparently.)

Everything was normal. In the end all we could think something was weird about the contactor. They took it out (I was off site at the time) and took it down to the substation to test it out.

With three phases connected to the contactor (and nothing connected on the other side) they energised the coil, and with an almighty bang it tripped the main incomer and took the entire sub offline.

Turns out there was a manufacturing defect in the contactor and sometimes for a millisecond, if the phase of the moon was right, it dead shorted two phases.

So there, even when you know everything, you don’t know everything.
