Just spotted red fluid dripping from front passenger side wheel, I have attached a couple of pics, any ideas what this could be from?

 

Vehicle is Audi S5 (2020)

What colour is the Brake Fluid in the reservoir? 

Never seen red fluid personally. 

Red power steering oil or ATF maybe.

I have also seen red assembly oil and thread lock but that should not be used on wheel studs. 

How many miles has the car done - you state 2020 year on your profile - if it were me I would pop down to my local Audi Dealer and let them decide. 

Hello David, 

Thanks for being in touch. 

As Tom says, if your car is a 2020, then the last thing you want to do is to worry why it’s leaking any fluid. You need to arrange to get it back to a dealer as soon as possible. Brake fluid and red in colour? I don’t think so, but whatever, urgency and safety is of paramount importance. 

For what it’s worth, red fluid sounds if if it could ( in caps) be a coolant leak.

Perhaps you could let us know the outcome.

Kind regards,

Gareth.
