Function and location
The instrument cluster displays the speed as well as the total and trip odometer reading; it is driven mechanically via the speedometer cable from the transmission output. The same housing also holds the combined gauge for fuel level, coolant temperature and oil pressure, as well as the analogue clock. The displays are backlit and adjustable via the instrument dimmer. The speedometer's scale end value is 180 km/h, the oil pressure gauge is scaled in bar.
The instrument cluster sits in the dashboard directly in front of the driver and is inserted from the front into the instrument carrier. It is connected via the speedometer cable at the transmission output as well as the plug contacts on the back.

⚠ Important: compare the part number before buying
What matters is the speedometer ratio: the factory sticker with the speedometer ratio is no longer legible on this unit. The speedometer ratio depends on the rear axle ratio and tire size, not on engine size – a speedometer with a different value will permanently read incorrectly despite having the same scale. Please compare the part number of your old instrument with the one stated above before buying, and contact us with any questions.
The scale must match: this instrument has 180 km/h. Instruments with a different scale carry a different part number and are not directly interchangeable.
Does not fit:
- W123 with 220 km/h scale (280, 280 E, 280 CE, 280 TE)
- W123 diesel with 160 km/h scale (200 D, 220 D, 240 D)
- Versions in miles (mph) for the US and UK market
- Instruments with a tachometer instead of the clock
- other model series such as W114/W115, W116, W124 or W126
