Audi A5 Rear Main Seal Replacement DIY | Transmission Reinstall + First Start

In Part 2 of this 2-part series, I finish replacing the rear main seal (RMS) on my son's 2013 Audi A5 Quattro 2.0T. This job required removing the transmission, which sounds intimidating — but as a 100% Certified Amateur, I wanted to see if this repair could realistically be done in a home garage without professional training. In this video I show: • Installing the 034Motorsport rear main seal upgrade • Reinstalling the transmission and drivetrain components • Reinstalling the starter and torqueing everything to spec • Replacing the diverter valve while I'm in there • Tips for transmission cooler lines and reassembly pitfalls • The first startup after the repair Rear main seal leaks are a very common issue on Audi / VW 2.0 TFSI engines, and shops often quote $2,000+ because the transmission has to come out. The goal of this project was simple: Can a DIY amateur mechanic complete this repair at home and save thousands of dollars? By the end of this video, you'll see the results. If you're tackling a rear main seal replacement on a B8 or B8.5 Audi A4 / A5 / Q5, this video should give you the confidence to take on the job.
