Hello. I have a 2010 Landcruiser 200. Last March a "VSC system inspection needed" message appeared. I was told by Toyota dealer that It is a common signal when some failures need to be checked and also that engine loses power as a warning. 2 Air blowers were replaced and paid 1,500 dlls. Now, again same message appeared (same synthoms: lights on the dashboard and lose of engine power) and now valves must be replaced. I will appreciate any thoughts on the above as I don't understand how the message (which by tje way relates to loss of traction issues) relates to the couple of answers received from the dealer. Now the quotation is of 1,000 dlls.
