Hi all,
I drive a 55 plate is250, it has been bombproof since i got it 4 years ago all i have done is mot and service the car and do the things required etc brakes tyres those sort of things. Before my last service however, the engine management light came on followed by a warning triangle saying check vsc then the traction control light. I intended to to get it checked at the service but all lights went off. About a week after they all came back on again so i booked it into lexus but by the time i waited to take it to lexus they were off again. This happened a third time but on this occasion i told lexus to run my car until the lights came on again so they could run the diagnostic, which they did and found the fault code and fixed the problem. Shortly afterwards the lights came on again and this time i was told it was because my exhaust system was leaking gas where the downpipes meet the cat and the flanges would need replaced. I found a dealer who did this for me and since then everything has been fine (about 2 months). When i was out yesterday however i was doing about 35 in a 40 zone just cruising when all the lights came on again. I have no idea what is causing it but i drove the car all day yesterday with the lights on, everything works perfectly well. I got up this morning turned car on and all the lights were out.
I am clueless as to what the problem is. Sorry for the long rant, just wanted thoughts as so many have the same issue with the lights but different fixes.
P.s i had low tyre pressure on front right which i thought might have been the reason but when i put the tyre to the correct pressure the lights remained on.
