Rx 300 Problem

[Scully91]

Hi there, i have a problem with a Lexus RX 300 thats i am currently selling. I had the car valetted (which may be connected - water!!) and ever since then the engine management light is on and the VCS light is also illuminated too, to make matters worse the sat-nav wont work either, it says it is not connected to the exterior source or something. I had it put on a tester thing and it says there is a VSS fault or something like that which i believe is the vehicle speed sensor. The mechanic cant understand why how the VSS is faulty but the speedo still works but anyway does anybody have any ideas what to do to try and rectify matters.

I must say the car has run perfectly before this. Thanks in advance for any assistance. :D

try find out if the valeters used a jet wash / steam cleaner on the engine - may well be that u have water in the connectors and its causing the fault

Yes, they did, now what !!

disconnect each connector and check for water, spray in a little WD-40

wd-40 will do but if you can get hold of some electro cleaner from maplins etc that would be better as it will orce out any moisture then also evaporates within a minute

Done my best with the connectors and done 500 mile so plenty oif heat got round them parts so what next coz its still doing it....or not doing it as the case maybe

Think you need to take it to dealer and let them track down where the water has gotten in.... they should be able to trace all the connections and work out what the issue is..

...cant see it being cheap ! Never a good idea to get engines cleaned, way to much electronic in there these days to get water into...
