Wouldn't be the first time the dealership was telling customer complete BS assuming that they don't have a clue in order to either get out of a warranty repair or to inflate an invoice.
Also dealerships not having a clue is not rare either. Many garages these days only connect a computer to the diagnostics port, download whatever error codes are shown and tell the shocked driver that half of their car is kaputt with the repair likely going to be several thousands of euro.
All the while the real problem is a blown fuse for one of the control units or a wire has chaffed and broke somewhere - and the diagnostic codes come only because the ECU can't talk to some sensors because part of the vehicle's CAN bus is down.
As another commenter mentioned, this is actually expected behaviour [1]. Because it’s precedented, it’s treated as okay [2].
To me, the car broke. Plainly and simply. And had Tesla had a similar fuckup, I don’t think they’d find sympathy. (Reasonably.) That’s something that comes with a longevity.
Yes it should be better documented. I ran into this as well on my Subaru, but once the cap is on proper it -should- turn off within ~1hr of driving (constant or short trips)
To wit; if you don't put AdBlue in a diesel it will eventually outright stop working altogether even though it's only there for emissions.
Yes but by saying those particular words, thousands of dollars left your bank account and entered theirs. Is it possible that is the only reason they said them?
I wouldn’t have linked the two had the dealership not told me that was what caused it.
