I had this getting gradually worse for months, it can come and go, in the end a new starter / solenoid from a breakers fixed it for £90 fitted.

What year is it? 1998, 152k miles How long have you owned it? 7 Years Did it come with Full Lexus History? Yes Have you had any problems with the ABS pump? No

Yep, mine is the same, always has been.

Does it surge forward when you switch it back to Petrol? Mine is noticably faster on petrol despite an expensive multipoint LPG system. I do have plenty of power on LPG though which you don't seem to.

Not much help, but my 1993 LS was similar, and its was also the case slightly with my GS before i changed to an iPod. Daniel.

The screen, the box in the boot recieves the button presses via the network - if that wasn't working the whole system won't boot up.

If your not sure - just disconnect the battery for 15 mins - that'll reset everything.

It runs from the radio (2?) fuse in the engine bay - i think its one at the end.

The emv is the "electro multivision screen", i.e. the touch screen monitor, sounds like yours is broken...

Sounds like the emv screen then, the LS400 looks the same but it doesn't have the temperature displays on the EMV they are on a seperate LCD.

I have 32k miles on my Prinz system with Flashlube, i had to change my plugs from the standard ones though as it started misfiring almost as soon as i had the conversion done. No problems since the new plugs. I think cars that do long motorway distances are more likely to be affected because they have a relatively short time running on Petrol, if your only doing 30 miles then the first mile is Petrol anyway. Daniel.

Does it beep when you touch it even when it doesn't work? Is the problem just in NAV mode or also in Audio / Menu?

Can anyone confirm if the model of the CD changer on the Mark 4 LS400 with the CD based satnav is 86270-30150 (same as the GS300)? Also, is there any instructions anywhere on how to remove the changer?
