It is nothing to do with the pick up or filter. I tried all these things with NO success. The French service manager has had this problem a dozen times and told me straight away it was the valves.
Thanks for pointing out the other post but I hope I can stop anyone else wasting the hours and money I spent with new filters etc.
There is another post about stalling which I answered and turned to be the same problem.

Thanks Again


Hi Scotspea,

after the scv valve replacement, did you experienced any other problem?
Thanks

Hi, The car has run perfectly since and the power increase was amazing. It had obviously been gradually worsening until getting to the limp stage. I had even pulled the connectors off the valves to clean them and now wish I had changed them myself (just four little allen screws and everything comes in a kit so it is simple and would have saved me a bit of dosh.

Bit of a late add to this post. But needed help.

Only just bought my LC 120. 2003. Thought it would be an problem free car. But noticed when I drove it on the motorway the engine light came on after about 8miles of driving, light would turn off but would come up again on the way home, again after about 8 miles.
AA came and checked, they said it's injectors. Took it to a diesel specialist, they've said it's fuel pump related. Low pressure.
So this is a Bosch garage and his logged in the fault with Bosch technicians. Some have replied that it's the red green valves. I would probably think it too, theres no start issue or rough idling, just engine light and possible lack of power.
Cause I have AA brc, I'm wanting to make sure it's covered the right bit. Is it worth me putting in a reconditioned Lucas pump from Europarts or stick in the red green valves.

Also would like to add that I've spoken to Toyota UK about this issue. Of the red green valves. They responded by saying very carefully that this is NOT a known or common or recall fault, but ' room for improvement from Toyota' so basically saying it's a known issue.
Also these valves cannot be bought separately from Toyota. Toyota only sell the whole pump unit, £1700+
So where is the best place to pick them up from?
