Have purchased relay 461 from Local Audi garage part number
y A03G 907 282 B. Initially all description numbers were supplied to Audi parts person, ie to 8A09512353, j179 and 461. First two printout descriptions did not satisfy me that it was the correct item that sensed ambient temperature. Requested parts person to concentrate on the item with 461 on its top. Cost was £99.12. Will pick up item in a couple of days but will not replace original 461 until colder weather is present, when I will compare both cars. I was aware that a 461 relay could have been purchased at half the price via e bay, but my 90 is worth it. To be continued....!
