Flashing coolant light vw jetta3/19/2024 ![]() Production changes and updates were made to keep the system current with the changing California and federal emissions requirements. Nearly exclusive to the European market, Volkswagen AG subsidiary Audi AG also used the Digifant system, namely in its 2.0 E variants of the Audi 80 and Audi 100.ĭigifant is an engine management system designed originally to take advantage of the first generation of newly developed digital signal processing circuits. Lower-power versions (without a knock sensor), supercharged, and 16-valve variants were produced. Other versions of Digifant appeared on the Volkswagen Fox, Corrado, Volkswagen Transporter (T4) (known as the Eurovan in North America), as well as 1993 and later production versions of the rear-engined Volkswagen Beetle, sold only in Mexico. Digifant as used in Volkswagen Golf and Volkswagen Jetta models simplified several functions, and added knock sensor control to the ignition system. Subsequently, Digifant II was introduced, adding ECU integrated knock control and idle stabilization, while externalizing an Ignition Control Unit (ICU). This system combined digital fuel control as used in the earlier Digijet systems with a new map controlled digital ignition system. Digifant was designed by Volkswagen Group, in cooperation with Robert Bosch GmbH.ĭigifant is the outgrowth of the Digijet fuel injection system first used on water-cooled Volkswagen A2 platform-based models.ĭigifant was introduced in 1986 on the 2.1 litre Volkswagen Type 2 (T3) ( Vanagon in the US) engine.

Have taken to VW dealership twice now for the problem and every time they have said there is no fault code when scanned so they don't know what the problem is. I have once checked the engine cold and the level was fine only to have the warning when I started the engine so I don't believe it's an issue with coolant expanding/contracting from below min to above after starting. I have even started checking the coolant level before starting the engine incase I can catch the level being low prior to starting the engine and the fault appearing. To clear the problem I simply turn off the ignition and restart the engine and it goes away however it's quite nerve racking and frustrating that it happens ~ twice a week. Every time I open the bonnet and check the coolant level it is well above the minimum line, around where the middle of the reservoir is. The MFD also displays "Check coolant level". ![]() ![]() Since my last service 45k, I have started to get a flashing/beeping coolant light on startup first thing in the morning after a long drive (45 mins +) the day before. Just seeing if anyone has experienced a problem similar to me and what they did to fix it. ![]()
