I agree this will come down to good will.
The dealer works on the car, not the owner.
In a way this is no different to wife taking the car in first time, and husband taking it back to say it's not been fixed.
Even if we assume both parties are male, they could be partners, or the car could be owned by a small business with several users, or any number of other scenarios.
The change of ownership is much less important than the timescale.
If the first work was done some time ago, the dealer may claim it's a new fault.
Garages are known to make best guesses at changing bits and charging the customer each time until the problem is fixed.
The OP's case is stronger the more recently the original work was done.
I would take the car back, present the old bill and simply say the problem is still present.
The first task is to get the problem fixed.
From then it's a matter of negotiation.
I think the OP can reasonably expect a discount off the bill for the new repair.
But proving the original diagnosis was wholly incorrect is impossible, so it will come down to good will.
