I have a 2010 Audi S5 V8, which is developing some weird issues.
Issue number one,
- When starting the car, we have to press the clutch very hard so it starts, if I do not do that, it will display message to press the clutch to start engine.
My mechanic has been working on the car, we already replaced the master cylinder, slave cylinder and it got a little bit better but now is the same again and most of the times the car will not start at all.
Clutch seems to be okay, no slipping and goes through gears with no issues at all.
Issue number two.
- One day I took the car out and when arriving to the car it wouldn't start, I thought the issue was related with the clutch issue but sometimes, you could hear the engine kind if cranking and stoping before the engine start.
I've called AA, they tested the battery and said I needed to replace it, we end up starting the car by pushing it with his van and then drove the car home.
When I driving home, I've noticed radiator fan was on all the time (which it didn't before the car ran out of battery).
Spoke with my mechanic, replaced the battery for a new one, cleared codes and still the fan was always on (fan on the right side of the car).
He has now been with the car for a few weeks and had an auto spark looking at it, which could not find any issue, they replaced the radiator fans resistance, made no difference, no DTC codes, nothing that could lead us to a solution.
Because I needed the car, he decided to disconnect the fan which was causing the drain and connected a temporary switch so I could start the car.
Did anyone had a similar experience and can lead me anywhere?
This S5 is driving me insane
