Funny story:
Some time ago (and I had forgotten this until recently) I bought a new fuel cap from Toyota/Lexus. Dug it out today to see if it would resolve management light issue (possible EVAP issue). A couple of days ago I spoke to the main dealer's twelve year old service-techie about the possible cap issue, after all it is a well known fault. Really, no never heard of that, so not a common fault to this highly trained tech sort.
Anyway I digress, hilariously as although the cap won't fit as they sold me a bayonet rather than a screw fitting, it has printed on it:
"NOTE: Tighten cap until clicks, or Malfunction Indicator Lamp may come on."
You couldn't make it up!
Anyway I have a brand new OEM cap, part number 77300-33070 going spare if anyone wants it for postage and an optional fiver to the RNIB.
UPDATE: Car's being trailered up north to a specialist next week. I refuse to scrap such a brilliant car without exploring every avenue
That's all folks..... 🙂
