This afternoon i thought i would fit my new thermostat,got the bolts out without too much pain!then i went to put the new one in but there was no O ring with the new part come to think of it i couldnt see a old O ring so i went to audi for it.So im back on the job but could not get the new thermostat to sit right after half hour of messing about i got a torch plus its getting dark.the old O ring was behind the thermostat so pulled that out and put the thermostat in then the O ring on top!got that nipped back up!pitch black by this point so i thought i would just put the connector i took off side of the alternator but cannot find anywhere had a good look with the torch still cant see it anybody knows where it runs frommay be i will just find it when its light also tried tracing back to the battery but still no joy!
