Water leak or a/c condensation? 335i

[SR20_Guy]

Hey guys,


Noticed a small puddle under my car recently in the garage. Seems to be after I've used the a/c so I figured it may be condensation, but the water doesn't seem clear. Seems slightly green/clear and feels slightly different to plain water when you touch it. Also, it comes from the front right of the car right where the bolt for the under engine cover fastens. A/c condensation outlets are usually around the bellhousing on most rwd cars.

Any thoughts?

I made a booking with BMW Zambezi. Hopefully it's a decent dealership? Centurion is closer to me but I recall reading they are not that great?

Could be a radiator leak

Sounds to me like a coolant system leak.. Best let BMW check it out!

Its probably a radiator drain plug . Had the same issue on my 135i .

ok so small update...

car's been at the dealer for a week. No leak according to them. So possibly the A/C condensation tube not directed backwards and water ending up on the splash tray.

However, they claim I have a slightly unstable idle. I have noticed on cold mornings that the car sort of "blips" the throttle on it's own when I come to a stop.

So they've been running all sorts of diagnositcs and cant find any faults. Updated software etc. Eventually BMW SA techy recommended 6 new injectors. And apparently its still the same. Anyone else had this before? It's almost unnoticable to me but the service manager insists on trying to sort it out.

They've also removed the intake to check for carbon on the valves, which was also negative,
