Had to pull up carpets and squeezed at least 2 gallons of water out of foam under floors, and kept in the sunlight every day for a week or so to dry it all out. Convertible top failed. Previous repair included resetting brushes on electric motor attached to hydraulic pump, but that did not work this time. Bought a new electric top pump motor from Audi dealership and self-installed.

I still had it taken to the garage but aside from resetting the CEL they could not find any problem. It had been quite cold (-20C) so they think that had something to do with it. I always run synthetic oil so it shouldn't have been an oil flow problem. They don't think it was actually low oil pressure as the CEL was unrelated but the engine noise to me seemed to point to it.

Audi A4 in British Columbia, Canada May 2016 - May 2019
Jul 2018 95480 mi C $350	Replaced front ROTORs and PADs. Pads had 6mm material left, but brakes pulsated. Rotors were worn unevenly. Suspect that car dealer where vehicle was purchased 2 years ago replaced pads only without replacing the rotors (which wear out together in every VW/Audi built in the last couple decades, and need to be replaced together)
Aug 2018 99200 mi C $390	Replaced passenger side XENON HID BULB of type D1S. Bought for $99.99 @ Canadian Tire. Because low-beam was burnt out. Original said "Philips". Replacement came in a Sylvania box, but lamp is OSRAM. Is so identical to Philips that I'm sure that both came out of the same factory. The window regulator was shot, as indicated by "crunchy sounds" when operating the power window. rnThe regulator for the Audi includes the entire window frame, mechanism, stainless-steel cables, and plastic pulleys. rnThe parts are pricey (CAD$341 from Audi -- there are no cheap Chinese knock-offs) but labour is very low, because its all one, pre-assembled unit. rnKelly and team at Sun Creek did it for around $400 plus tax. rnAt an Audi dealership it would have been double that price.

Jun 2017 157000 mi US $240	Replace fuel filter and fuel pump. Fuel filter had never been changed, after changing a CEL came on for too low of duty cycle on fuel pump. It was only because of the filter change, but researched it more and found out how to read the duty cycle in VAGCOM and it was actually reading around 76% at idle. Deciding to preventatively change the pump although it appeared to work fine. New fuel pump is around 50%. I believe the pump had premature wear due to the fuel filter never being changed.

Jun 2016 108500 mi	Rear window wiper was not functional due to water leaking into bearing. The wiper motor assembly was removed and modified so oil could be injected into bushing/shaft assembly. The motor was operated until it ran smoothly.
Apr 2017 122760 mi C $250	Front end developed noise over the winter. Worst noise was from driver's side front bearing. Required replacement but took a long time due to seized and corroded fasteners and components. After the drivers side was repaired, it was apparent that the passenger side front was defective as well. Once parts were obtained, that side was replaced.
Jul 2017 122760 mi C $2000	Flex pipe on RHS is broken. Estimated parts cost is $1500 alone plus $500 labour. Yikes. Intake flaps on one bank are stuck closed. Need to dismantle intake assembly to check problem repair-ability, which at the least requires $100 in gaskets, even if nothing is done. Valve cover gaskets are leaking oil again. The leak is bad enough to fill the spark plug wells causing misfires.
