Problem Finally Solved

[gareth1902]

So the longstanding issue of the tyre pressure warning on the dash telling me to check system has been sorted by Lexus. Wee fingers crossed this time anyway. Turns out it was indeed related to the installation of the rear DVD system I had installed by a car audio firm. Below is what Lexus wrote on the job note and it is quite worrying.....

"Disconnected DVD system. Found live wire wrapped around a fuse and pushed into fuse board for boot release. System earth wire wrapped around a bolt. Advise wiring to be fitted correctly from a direct power supply".

Oddly the boot release had no issue at all and worked fine, but somehow all of this affected the tyre pressure system somehow.

So a fuse and the ECU were damaged due to this poor installation. Obviously cost recovery from the firm is the next step but just wanted to say case closed.

Thanks for all help and advice and support over the last few months.

No doubt you will be having a deep and meaningful conversation with the "professional" car audio installers ??.

Very worrying that a so called professional installer would use such a bodge to wire in the system. I don't know about the mk3 gs but my mk2 has a power socket in the center arm rest and if the dvd system is a headrest install then this would be the ideal ignition controlled feed required. soldered and not just wrapped round conections of course!.
