Audi A4 Electrical Wiring Diagrams?

[Pauls898]

Hi

I have an Audi A4 3.0L TDI QSE on an 09 plate, I can't seen to be able to purchase a Haynes Manual for this car? all the A4 manuals I've found says it does not cover the 3.0L Diesel version.

The problem I'm having is an intermittent problem with the wash wipe action, sometimes it just refused to function? if after several flicks of the wiper stork then it will decide to functions flawlessly soI can't see it being the switch itself? I have also found the washer pump, removed that and that seems to test out just fine.

It's also related to the rain senor wipers to as while the washer system is down the rain wiper action is also defective? Once the get the washers working again with many flips of the stork the Rain wipers will also start to function normally again too? So the things are related?

My question is I need to find a wiring diagram so I can track what controls this function? Is there a wiper / rain sensor module I can simply replace?

This all seems to of happened after I replaced the Car Battery myself? Could this be related in some way?

Thanks

Any b8 repair manual will be ok, regardless of engine, wiper system is same, so go to erwin website or ebay etc etc...
