Hi all
i recently had the same problem with my Lux. 3.0 D4d 2010 Vigo. everytime i speed up to 160km/hr, check engine light came on and vsc off indicator goes on and vsc light blinks, car goes to limp mode. I dont have chip installed, yet. I only get rid off my cat and muffler, got it replaced with a straight through pipe.
as from what others experience, i thought it could be the MAF sensor being dirty. so got the CRC MAF cleaner and cleaned my MAF. but the problem still exist. so when i did a lot of researching, i just realised that people who had this same problem had done something with the exhaust as the check engine light is something to do with emission thing.
Im currently away from home for a week so cant do anything bout it at the moment. but once im back home, i might want to install back my cat and take it from there. Hope this will solve the problem
