Said the cost to change the Rotary Switch & the TDC Sensor is £390 + £88 diagnostic charge (£478). Also had the nerve to tell me i should replace my wipers as they were smudging the screen, i only replaced them in March!

Told him i couldn't afford to do any of that at the moment as heading on Hols next wk.... he said he would recommend getting the rotary switch done and told me he could do it for £280 all in, including the sh1tty diagnostic charge! how can he just drop £40 like that?!!
So just wondering if someone can tell me,
How much they've paid to have a TDC Sensor replaced?
Is it a job that i could possibly do myself? (like the igination coils)
How much for Timing belt change? Guy told me it would be (£370) through them.
