Since the spring my SMT pump has emitted a high pitched whine upon first priming (after opening driver's door).
The noise has gotten a little deeper now, but the actual system is working fine - and no fault codes/EML light.
Likely cause - low fluid? Worn out bearing/pump? It doesn't seem to be as noisy in use (although it's difficult to hear much over the engine anyways).
Any further advice willingly sought - I can probably upload a recording if necessary.
Toyota Tunbridge Wells are quoting £85 for a litre can, although the parts manager had never ordered it (in 15 years)...
Give this thread a read.... probably helpful.

Thanks, but it doesn't say much about noises...any ideas?
I suggest you send a private message to cyclehead, as he seems to have the expertise on the SMT.
Well, a quick top up of fluid and it's back to the usual priming noise.
Result!
Anyone want to buy a 90% full tin of Toyota SMT fluid?
