Recently acquired 2011 135I DCT with 97K. Already found a few things that need to be addressed.

Wondering what service/repair manual do you guys use? I've used Bentley for my E36 M3/4/5 but couldn't find one for this E82 platform. Do you guys just do E90 Bentley then? Have you had any experience with this.

Planning to do:
1. Coolant level sensor.
2. DCT complete service with gasket (leak).
3. Rear Diff service (sweating).
4. Refreshed all rubbers and bushings.

Thanks
