The smell of all the new parts, mainly plastic ones, coming up to operating temperature is normal. Having said that, it should only happen the first few times that you drive the car.
I know what smell you mean. I had that too, but now it's actually gone.
The clutch... I can't help with that as wherever I've driven so far, including steep hills and underground garages, didn't have any problems with slipping or smells.
I did not have a slipping clutch when the pedal was not stepped on.
Going down the entrance you'd be in first gear and on the brakes, so no clutch grinding /slipping there. Going up you should be also in first gear approaching the exit, no throttle, just rolling, and go up with as much throttle required. You shouldn't be on the clutch, or I didn't understand exactly what you mean.![]()
Sure going down the entrance is no problem
I have to park at the hill and wait until the garage gate is open. Then I have to start at hill and drive slowly into the garage. Therefore I let the clutch come up to the biting point and give some throttle. Without throttle it would go out, because it is too steep. Then it smells a bit like clutch in the closed garage. I never noticed it like that with any other car.
