Thanks for replying, appreciated. Tbh, Lexus garages are my choice of last resort (Lexus quote for loose heatshield repair: £185 + VAT + parts. Indi: free. Effect: same). My garage is an indi and anything he can't fix, he sends me to another indi (electrics specialist, also fully booked) who can. This is going totally off topic, but I came across a post about changing batteries in key fob and any suggestion to me about using a Lexus dealer to do this.... it seemed OK with some and i found that weird. My 8 year old niece worked out how to do it on my fob without prompting. As I say, that's all off topic, but I hatevthat car manufacturers tie you in to their brand. As a saying might go... Its not because I love Lexus repairers, its because I've got no bloody choice but to use the buggers! Anyways, that's all besides the point and I don't want this thread to go off topic. So, anyone have ideas about the misfires?
