Nice DIY write up...just a reminder for those who might not pick-up on the LHD/RHD aspect...using driver/passenger side can confuse some owners if they're not paying attention to the country of origin & the possibility of the poster having a LHD or RHD vehicle.
But if the terms left/right are used instead (with the understanding that left side/right side of the car is determined by the perspective of the driver behind the steering wheel) then it doesn't matter if the instructions are based on the vehicle being LHD/RHD.
But if driver's side/passenger's side is used...then one most be cognizant if the writer has a right had drive vehicle or a left hand drive vehicle to determine which side is passenger & which side is driver.
I really like the e70's REAR wiper...it has a sleeker more aerodynamic appearance vs the e53's rear wiper.
