Hello Everyone I will be taking my 335i in for service at the local dealer Reeves for the first time. I have JB4 G4 and was going to leave it on Map 0 for the service. The reason for my service is a Transmission leak it's either the gasket, sleeve, cracked pan (which I doubt), or mecatronic device. I have warranty for the car under a 3rd party where the transmission is covered. My question is will they find the JB4?
