With the ignition in position 1 you are using the battery terminal voltage to operate it. With the engine running this voltage will increase by approximately 2-2.5 volts which may be enough to push the current draw over the 10 amp rating of Fuse 10 which is the rear wash wipe. Door card off and disconnect the rear wipers and see if this makes a difference or disconnect M154 rear pump washer to see what it is that is causing the excess current, component or wiring, and replace or fix accordingly. If you go through life with your head in the sand....all people will see is an ar5e!!

Check the motor spindle hasn't seized. That's quite common.

Ok SO after a short while I really need to get this fixed.
I have isolated/disconnected the rear wash wipe and the fuse didn't blow when using the washer jets, so I guess I am to assume something is going on with the Wash wipe. Reconnected everything and its blown the fuse. Its moving ok so im thinking its probably not seized. Any thoughts on what to look for before I have to order a new one? Approaching MOT no need to fix. Thanks |

Lubricate the whole drive, especially where the spindle comes through the door..
It's putting an overload on the motor.  |

Ok I haven't entirely removed the unit to lubricate but will do
How ever playing at blowing fuses today if I open or close the door while the wash wipe is running it stops and has blown the fuse. I'm thinking a faulty earth but wanted any other opinions to point me in the right direction I'm getting through a few fuses Thanks |

I take it by "wash wipe" you mean rear wiper? If so, remove the rear door card and pull on the wires inside the rubber boot between the offside quarter panel and the door. I had problems in there with three broken wires and one bare wire. I pulled the rubber boot back and soldered all together and had no problem since. 2008 RS4 gone, 123d M Sport, and a Puma 90 XS..

Faulty earths don't blow fuses.
Excess current draw does. Motors having to work too hard because of seized or tight components draw excess current. A seized or sticky spindle is the most common cause of blown fuses and burned out rear wiper motors. Resolve this and you'll resolve your blowing fuses.

Solved! Its a bit random, but my swingaway wheel carrier has a small plate on the inside which is a bit loose and moves when you open and close the door.
Anyways its been rubbing on the wire at the top of the wiper motor relay and I guess caused it to short when the door was moved etc.. repaired it and all is well. Thanks for the nod in the right direction DOT |
