Hello all
The car is is250, RWD, MY2008, 130,000 KM, owned it 4 months

Today the Check Engine light + Check VSC appears together.
Yesterday i drove the car and i have nothiced that it drives regular, but one thing is wrong - there is a little strange noise like "KCHCHCH" when you slow the speed before stopping the car. (at 20 KM/h~)

Tomorrow when i wil go home i will check the error codes with OBD scan and let you know the exact error codes.
I checked the gas cap and its tighten, so its not the problem.
The battery is 5 months old.
The alternator is 1 year old.
The car has a fully maintenance history from the Lexux dealer.

What do you think that the problem is?

hi
the noise appears for only 1 second and then disappear, and you can really "feel" it like a little vibration.
the traction control light is on, you can see it (the orange light) in the right-bottom corner in the dashboard.

*UPDATE*

Earlier today i connected an OBD scanner and it showed error number P2714 Pressure Control Solenoid "D" Performance/Stuck Off.
I cleared the code and disconnected the battery for 10 minutes.

The situation now, after 20 miles (=~30km) driving, is that the car drives ok without any visible problem (knock on wood), smooth shifts between all of the 6 gears, good and silent drive in town and on highway, no idleing problems visible, and no Check Engine/Check VSC lights. Im hoping this will last and the code will never show.

So what is this code means? i've read some posts here and saw that some people replaced the specific solenoid and it solved the problem.

What is the part number and where can i find it for sale on Ebay/Amazon?, i dont care that i will have it untill it will be need a replacement.

In addition, according to the dealer's record, the transmission has never changed ATF so for now, I'm planning to do a partial transmission fluid change about 7 times by draining the drain plug and fill the same amount (about 1.5L for each change from what i've read) back to the transmission with new Toyota-WS.

So today the car popped up again Code P2714 Pressure Control Solenoid "D" Performance/Stuck Off + the transmission stuck on 3rd gear.
I talked with the dealer here and asked about any Updade available for the transmission, he said to come over and check the car and connect it do Lexus-iagnostic-tools and Update the software to see if it will solve the problem.

I will let you know in any update.

*Update*

(2nd time) The Error Code P2714 Pressure Control Solenoid "D" Performance/Stuck Off + Check VSC appeared agein 2 weeks ago, I cleared it and the car back to normal.

(3rd time) Today it happened again: P2714+Check VSC + the transmission stuck on 3rd gear and the rpm accelerated, I cleared it and the car back to normal.

Now im going to the dealer to check if there is any Update for the transmission and check if the problem is in the Solenoid itself.

(4th time) Today it happened again: P2714+P0751 Shift Solenoid "A" Performance/Stuck Off + Check VSC + the transmission stuck on 3rd gear and the rpm accelerated, I cleared it and the car back to normal.

Is ther anyone knows what Solenoid is "Shift Solenoid "A"?

There are 9 Solenoids, which one of them is "Shift Solenoid "A"?
S1
S2
S3
S4
Sr
SLU
SLT
SL1
SL2

So I went to the dealer, they did some software update to the transmission (A960E transmission), the vehicle works normally in the meantime.
They charged me for 100$ for the diagnistic+Update.
