As you may be aware, I value the process of diagnosing car faults to make an educated decision on what part to repair or replace. I do not appreciate a vague problem being commented by many as to replace this and that part. More often than not, these guesstimates lead to the replacement of parts that are perfectly good and do not lead to fixing the problem, while spending a lot of money. Worst case, the bad new part may introduce a new problem!

In today’s case, I’ll make an exception to that rule. A good friend had a problem with the AC in his Audi A2 not working anymore. A friend of his, a renowned specialist on these particular vehicles, had already diagnosed the problem and provided my friend with the part to be replaced, an AC temperature sensor.

This story is more about the replacement process and not so much about the diagnostic process to find that particular error.
