2014 A5 Premium Plus Cabriolet Quattro 2.0T
Any bets whether I've got an issue still to deal with, or just had mechanics leave a little too much mess behind? Read on... I had my radiator coolant changed yesterday in my 2014 A5 Q 2.0T Cab (68,000 miles) by an independent shop new to me but apparently well-respected. Today, after driving about 15-20 miles total after the service, I noticed about 1-2 teaspoons of coolant (pink) in two separate little puddles on my garage floor, corresponding to the two different parking placements I had used for the car. I took off the belly pan and clearly saw earlier this afternoon that the drip location is at the radiator drain valve (lower left front corner of the car). There was a bunch of wet slippery looking stuff all around the lower left corner of the radiator. I quickly returned to the same shop today, leaving the belly pan at home. They hoisted the car on the rack and did a pressure test, reporting no loss of pressure. They ascribed the slippery wet look also to the silicone lube used for hose reinstallation. Of course I will continue to monitor my coolant level, and watch my garage floor. But is it possible to sling around too much coolant while doing a change, never getting it inside the radiator to being with, that it would spill out later while driving? Or get "burps" after coolant servicing, that spill fluid even though the system is tightly sealed? I am positive that my car's coolant level was steady for months and months at a time, up until yesterday.
