every day there is a puddle of fluid under the front of the car on 2003 Volkswagen Passat

after changing the oil the tech said said he saw fluid around the transmission but didn't explain further. This was an express service at the dealer

Have them show you?Get WRITTEN estimate. Get it fixed before it costs you a trans.
After the oil was changed there were no puddles for four days. On the fifth day there was a leak of at least two feet long. I touched the puddle and it was clearly the new oil. the next day there was only a dinner plate size puddle. I have an apt at the service dept for tomorrow. What's your guess.
