my golf 4 says stop check coolant then service manual
2 Answers
Did you check the coolant level ? If so, it may be a reminder to flush the system and fill with new fluid

Hi I also have a MK 4 GTI AGU. I have replaced the expansion tank and the temp sensor but still the warning shows on the dash. The car is running at normal temp. I have had it diagnosed on VAG and no faults picked up. I am beyond frustrated. Any help will be welcomed. Quinton Cape Town ZA
