What a rip off! I asked how much it would be to change the headlamp sensor to clear a fault. They could have answerd the question on the phone, but instead they asked me to bring the car in and have a look. They kept me waiting for two hours and then told me that the headlamp sensor needed replacing. Yes, I know!! Then they charged me £80 for telling me what I already know.
When they did finally give me a quote it was nearly £300 for a sensor I can buy on EBay for £30 and what Snows told me was half an hour of labour. Still, I suppose if you walk into a main dealer they assume you are an idiot.

Snow's reply below is awful! I didn't ask for a diagnosis, I asked how much it would cost for a new sensor. What possible liability is there in saying "a new sensor (if required) would be £300?" That would have saved me a lot of time and money. ..... And no, I was not told that Snow's charge £80 for estimates. I am happy to continue this discussion on Google, or you can talk to me privately. Service like this belongs in the 1970s.
