Vsc Warning 2008 Gs300

[SiWall]

Hello all, hoping you can help. After months and months of trouble free and happy motoring, yesterday I let the wife use my Lexus while I used her BMW X3 to take the kids to the beach! Obvious reasons. I hate sand in the car!

For some inexplicable and less obvious reasons, she returned the car back with 17 miles in the tank. My son turned the car around on the drive to make room for his car to park and there it sat u tip this morning.

The car is now lumpy on idle and the VSC light is on along with the engine sign and the warning exclamation sign as well. I'll get some 98ron in her in the morning (the car not the wife).

Any ideas apart from...

1. Divorce

2. Don't lend her my car again

fill the car up and make sure gas tank cap fully on

for some unexplained reason this happens if you run it low on fuel

it will go off after a few restarts

I have also had my GS300 sounding lumpy when starting it when it is low on fuel and been sat for a few days. 200 yards down the road and it is fine again.

I also had the VSC light a few months ago, probably because I added Redex to a tank of super unleaded. The VSC light seems to show when there is an issue with the O2 sensor. Simply refueling removed the light very quickly.

You should never leave a car on reserve fuel, all the rubbish gets into the engine causing eml to come on, and always use good fuel, not the supermarket rubbish

Ok thanks I've put £30 and some redex in as I suspected the dregs of the tank would upset the engine. VSC still on for now but I'll keep using and see what happens. I've read about resetting the fault using a paper clip to short the circuit on the board...or disconnecting the Battery. If it doesn't go by tomorrow I'll try this. I didn't fancy a trip one hour up the coast to see my nearest Lexus dealer and hand over £150 for the pleasure of connecting a diagnostic reader!

£60 seems to be a standard code reading fee.

If the fault has cleared then the warning light should go out after three journeys (engine start cycles).

[Mike Hartland]

Just to clarify - the VSC came on with my car (I suspect) because I put Redex in the tank. I am not sure that it is a way to clear the fault.

[SiWall]

Lol I realise hat but given the fact that the tank had probably dredged up the mucky stuff in the bottom I figured it could do with a bit of a clean as it ran.

I too had this problem, vsc, stability control, abs and engine management lights ll on, coincidentally after refueling on two occassions. Took to Lexus Wolverhampton, and the super highly trained technicians decided on a £2500 fix for Ecu and 2 oxygen sensors. I declined and following searches on this site and US sites, replaced the petrol cap for £26, problems solved. It appears that the rubber seal on the petrol cap weakens, when you start the engine, the tank pressurises, but sucks air into the system and sets off the christmas tree lights.

Perhaps I should have been a Lexus technician!

After that lost faith in marque and dealers, had VW Touareg V6 for last 2 years, and I must admit I do miss the creaky dashboard.. Not!
