The bumper does not need to be removed. I replace my compressor with a new one and also replaced the dryer which gets overlooked on my driveway without issue.
I had a friend empty prior to work and then refill with gas after.
This is the CONDENSER not the COMPRESSOR.
Indeed. Not that bad a job tbh. Bumper skin comes off pretty easily and then it's just bolts and screws.
FWIW, the OEM condensor is a lot better than the aftermarket ones.
And for the compressor for anyone who needs one: P/N 1K0820808F, made by SANDEN. £800ish from VW.
Worth changing the receiver/drier whilst you're there and also the prone to failure pressure switch.
Not a cheap game keeping cool.
