possible stuck fan relay relay remove relay and test with a meter

Hi,normaly there are parts of cars that fit other models but if they do thay usealy have the same code numbers on them,so if the code number is different I would not try it as they will differ some what.
but if you realy want to be abserloutly shore ask a audi machanic.
hope this was some help all the best.

Alright it gets complicated...
I'm assuming you have a 4L (2005-2015) model.
It will be in the under bonnet (hood) relay panel.

It can be any two of five relays depending on engine and year!
For petrol engine models up to June 2009 it's relays A1 and A2.
For petrol engine models from June 2009 it's relays A5 and A6.
For diesel engine models (3.0 and 4.2) it's relays A5 and A6.
For diesel engine models (6.0 V12) it's relays A2 and A4.

For all fuse and relay information (RHD & LHD) see here:

No.# 31 fuse (25A - white colour) placed in the engine bay fuse box / relay plate, is for the front windscreen wipers for an Audi A3 2005 2.0 TDI. See pictures below:

i do not know but give these websites a try www.alldatadiy.com and www.autozone.com if all fails stop by your local library and get your hands on a Haynes auto repair manual for your car wish you the best of luck Michigan Man.

You mean the magic multipurpose relay or the multifunction magic realy ,diesel jaguar now that is sacriledge to us purists ,its a mondeo that changed shape .Anyway not sure which relay it is off hand but please describe the fault a bit more becuase as its a "jaguar" then the electrics are lucas and only good components are used not made in china .So if i knew a bit more of the problem i might be able to diagnose the fault a lot better

Go to this web site: http://www.genuineservice.com/genuineservice/en/default?page=genuineService Pick owner guide on the left task bar. Input your vehicle info then pick get owner guide. Pick owner guide 5th printing and your fuse info begins on page 176

do you mean how... or where is it located.... look under the hood for the fuse panel located there. basically you find the correct relay ... pull it out and replace it. there are more relays under the dash and i've heard the audi's also have them in the trunk.
