This weekend we were down to -16 deg C.
The rear washer jet must have frozen despite having almost neat screenwash (good for -32 deg c apparently)
The pump pressure must have blown the hose connection appart, hence about 1/2 litre of screenwash has been pumped into the passenger footwell.
This is the second leak I have had...the other was more serious...rain water flooding into the car from the engine bulkhead.

Our allroad also suffered the problem of the leaking washer hose.... Come on audi!!!..either install a pressure relief valve that vents to outside the car or design a hose that can with stand the max pump pressure.

J,

I have the same problem with my BMW 5 Series. The hose is forced of the rear washer nipple and then soaks inside the tailgate. On this occasion it has caused the boot switch to frazzel itself, which stops the boot closing. Because of the snow BMW can't get the spare parts to my local dealer, thus my car is just a pretty statue in the snow.

Eagerly awaiting my Q5 though.

It may not have frozen - the rear jet on my Q5 stopped working in November, before the cold weather. Turned out it was just blocked by dirt... as I'm sure most of us already know the entire rear area has a tendency to become quite grimy in wet weather. A bit of cleaning and a little compressed air did the trick. Luckily the hoses held up, and I'll be cleaning on a regular basis on account of Johnny's misfortune...
