Hi all,
Samething happened to me over the weekend. ERR3!. Call lexus and enq about the 5yr/100,000miles warranty and as suspected it is 5yrs OR 100k whichever comes first. Not bad my car is an X plate 2000, although i've only clocked up 62k. Quoted me anywhere bet, 400-700 quid to repair. new one would cost 1k plus. I was looking to replace it from ebay/salvage yards etc but as someone pointed out that will eventually go. So it looks like an after market for me.
