Hi folks,
first post,
I bought a 2007 IS220D in April 2013 and have struggled with VSC Faults until the present day. I first googled it but not too much and discovered it could be anything at all. The important part I found was that that disconnecting the battery clears the fault. You will however have to re-set your clock and your windows. The fast open close won't work on the Windows. To re-set the Windows you have to fully open and fully close each window on its own door respectively. Only then will the master control on the drivers door work again.
Things that caused my VSC Faults included
1-Hitting a pot hole
2-drifting round roundabouts...
3-not changing the oil in a long while
mostly of course the fault came on during normal driving and mostly it went into limp mode but not always. I have discovered that the car is dead in low revs (below 2000) a few weeks before a VSC fault will appear.
I no longer fear the VSC fault as I know it can be quickly cleared by the good old battery off and on technique.
I'm one of those idiots that drives too fast most of the time and this will probably lead to my untimely demise though with age and a family I am driving less like an idiot. I only say this as this differing driving style has had a noticeable affect on the frequency of my VSC faults.
maniac driver-2 VSC faults a year
normal driver-8 VSC fault a year.
i got one today and straight away went and got the oil changed as it had been a while. The fault cleared.
so I came on here to finally Google this VSC Saga once and for all. To my amusement it's a common thing and reading all the comments on this thread about cleaning the Cars system either the DPF, Air sensors, driving at high revs etc all makes sense to me and to my own experience.
In conclusion I belive the VSC faults are created by a blocked up exhaust system probably from supermarket diesel as we all know it's not refined as much as top quality brands, same with petrol. I had a friend who had terrible performance instantly with his BMW Z4 from Supermarket fuel. All the cleaning sensors and burn outs seems like good advice.
Feel sorry for for the guy who lost £13k selling his Lexus. Do not fear the VSC, disconnect the battery to get home, then proceed with the 3 or 4 cleaning methods and you should be fine.
