The MGF and MG TF use the term "auxiliary gauges" narrowly. On these cars it refers specifically to the factory centre-pod gauge pair, the analogue clock and the oil temperature gauge, that sits between the speedometer and tachometer in the instrument binnacle.
This is a single small pod containing two gauges, one above the other, or in some trim specifications one gauge with the other position blanked. The items catalogued here are original-equipment replacements for these specific factory positions. Dashboard-mounted aftermarket gauges for boost pressure, oil pressure, voltage, air-fuel ratio, and so on are not catalogued on this page; those are the domain of specialist aftermarket suppliers rather than the original MG parts range.
The Analogue Clock, Three Face Variants
The analogue clock changed face colour alongside the main instrument cluster, producing three distinct variants. Pre-XD511058 MGFs use the cream-face clock that matches the original MGF instrument set. MGFs from VIN XD511059 onwards use a silver-face clock matching the MY2000 facelift cluster. MG TF uses a separate silver-face clock, visually similar to the MGF silver-face variant but catalogued as a different part, reflecting minor mounting or calibration differences between the two bodyshells.
A 2-watt BA7s clear bulb illuminates the clock face whenever the ignition is on; because the bulb runs continuously with ignition, it is typically the first illumination item to fail and is an owner-level replacement without cluster removal.
The Oil Temperature Gauge, Five Production Variants and a Safety-Relevant Upgrade
The oil temperature gauge occupies the other centre-pod position on cars fitted with the gauge (some early trim specifications used a blanking plate where the oil temp gauge would otherwise sit). Five variants are catalogued.
Early MGFs to VIN AD001017 have a 150°C-scale cream-face gauge. From VIN AD001018 through XD511058, the gauge scale increased to 170°C (still cream-face). This scale change matters in practice: the K-series can exceed 150°C oil temperature under enthusiastic driving on a hot day, so original 150°C gauges can show red in perfectly normal enthusiastic use. Upgrading to the 170°C scale gives a more realistic reading range and removes false-alarm stress.
From XD511059 onwards, three silver-face 170°C variants are catalogued, for MGF non-VVC, MGF VVC, and MG TF, reflecting different sender calibrations across these engine variants. The oil temperature gauge bulb (1.2-watt capless) is catalogued separately, along with a common mounting kit (O-rings, clamp ring, and four mounting screws) that serves both the clock and the oil temperature gauge.
Fitting and Maintenance
Both gauges are retained by the same mounting hardware, a rubber O-ring seats the gauge body against the pod aperture, a clamp ring and four small screws hold it in place from behind. The gauges are removable from the pod as a pair or individually from the back of the instrument cluster, which must be partially withdrawn from the dashboard to access. Bulb replacement is possible without cluster removal for the clock; the oil temperature gauge bulb is less accessible but still straightforward with patience. The mounting kit components, O-rings, clamp ring, screws, are catalogued individually for owners whose originals have perished or been lost.
