Mercedes 1975 ~ 1998


Mercedes / ford vdo 83.601VDO 76.501 Mercedes W114 W115 etc


Mercedes has two different type of cruise control systems. The oldest system uses a vacuum regulator with analog amplifiers which have 10 or 12 pins (1975 ~ 1980). The more “modern” system (1980 ~ 1998) uses a digital amplifier which has 14 pins and an electrical motor. For these systems many different cruise control amplifiers are designed, for all the different car models that exist. However the amplifiers can be divided into 6 groups, amplifier started with numbers:

Group 1: 412.203.. (10-pin amplifiers, 12 Volt)

Group 2: 412.216.. (10-pin amplifiers, 12 Volt)
Group 3: 412.205.. (14-pin amplifiers, 12 Volt)
Group 4: 412.212.. (14-pin amplifiers, 12 Volt)
Group 5: 412.405.. (14-pin amplifiers, 24 Volt)
Group 6: 412.412.. (14-pin amplifiers, 24 Volt

The above mentioned cruise control amplifiers fails quite often. Common failures are: cruise control doesn't work, falls off during use, can not hold the speed properly, doesn't stop accelerating, etc. Some of these problems (cruise doesn't work or falls off during use) can also be caused by bad switches (brake, clutch, on/off) or regulator, the best is to check this first.
