This is my S3 thread. There are many like it, but this one is mine.

Car is getting Opti-coated but while it's away some other toys showed up. Rear sway, pulley kit, and KW delete kit. Just waiting on the coil overs and end links now. Also decided I'd get a whole new detail kit for my whole new car. Always been a big fan of Adam's Polishes but over the last year I tried a few things from Chemical Guys and really liked them. Decided to go a bit nuts and buy a bunch of stuff from them.

Had my car opti coated and added the plus last weekend, I couldn't be any happier

Post pics of the car once you pick it up.

I would highly recommend not installing the crankshaft pulley. The stock damper absorbs vibrations from the crankshaft and reduces stresses on your motor. The Neuspeed pulley does not have the damper and will actually cause harmonic vibrations in your motor and can cause issues down the road. If anything I would do a Fluidampr, but I don't believe they are available for our cars yet.

Interesting. I had the Eurocode pulley installed for 40,000+ miles on my B8 A4 with no issues nor have I seen anyone with any, at least not on that platform. The only way you should end up having problems is if you let the crankshaft move out of TDC during the removal/installation. From Eurocode's introduction of the pulley:

There is a common misconception that the factory crank pulley is a harmonic balancer which is not the case. The Volkswagen/Audi TSI engine's rotating section is fully balanced from the factory prior to the accessory drive pulley being installed.

I realize it's a different platform and technically different engine but the install process is very similar to the Eurocode one and neither mention anything about dampers.
