I have had a warning light for 6 months now. The tyres are all newish and I do less than 3000 miles per annum. But the MOT is coming up and I've had to approach Lexus Poole. They want £216 just to tell me that the TPMS needed replacing. I told them that but they wanted £216 to diagnose the problem (when they know what it is) before they would start. I argued the point and they agreed to replace 3 sensors (one of the 4 is only 3 years old) without the £216 fee, and for the 3 they want nearly £900!!!!! £150 per hour for labour, which in itself is an assault on my intelligence. They want an hour to replace each one. Good lord, I'm 80 and I could replace a tyre valve in less than 30 minutes and even less with the right equipment. I wonder why Lexus, who make a great car, want to put me off buying another. If I'd paid the diagnosis fee I'd be looking at £1100, just to change 3 valves. It is without a doubt a stickup! I can do nothing but surrender with my hands up and pray they don't shoot me.
