The MGF and MG TF instrument cluster exists in two fundamental specifications split at VIN XD511058/XD511059. Early MGF cars up to XD511058 use a cream-faced cluster with the traditional MGF interior colour palette. From XD511059 onwards, as part of the Mk1/Mk2 facelift that carried through to the MG TF, the cluster changed to a silver-faced design with revised graphics, redesigned illumination, and in some positions LED indicator bulbs replacing incandescent ones. The two cluster eras are not interchangeable, mountings, connectors, printed circuit boards, and warning lamp layouts all changed with the face colour.
Ordering any cluster component requires establishing which era the car sits in.
Speedometer, MPH or KPH, and Matched to the Car
Every speedometer assembly is catalogued in both MPH and KPH variants, critical for ex-European-market cars or UK cars that may have been imported at some point in their history. For silver-face cars, speedometers further split by manual versus automatic transmission, and for MGF specifically by non-VVC versus VVC (total of six silver-face MGF speedometer part numbers plus six more for MG TF). A speedometer from a different transmission or engine variant will not calibrate correctly, the signal processing within the cluster is matched to the expected sensor input and gearing. A trip reset knob is catalogued as a small part for owners whose original has broken off or been lost.
Tachometer, Calibrated to Engine Variant
Tachometer assemblies are engine-specific, reflecting the different rev limits and normal operating ranges across the MGF/TF variants. Redlines are 6,800 rpm for 1.8 non-VVC and TF 135, approximately 7,100 rpm for VVC engines (Trophy 160 and TF 160 rev somewhat higher still), and 6,000 rpm for the CVT automatic. Fitting a tachometer from a different variant produces incorrect redline marking and occasionally incorrect needle response across the range. Silver-face tachometers are catalogued separately for MGF manual non-VVC, MGF manual VVC, MGF automatic, MG TF manual non-TF160, MG TF 160, and MG TF automatic, six distinct part numbers for the later era alone.
Fuel Gauge, Temperature Gauge and Complete Instrument Packs
Fuel and coolant temperature gauges are catalogued separately from the speedometer and tachometer, and split by face colour (cream or silver) and by model (different fuel gauge for MGF silver face versus MG TF silver face, despite both being silver). Complete silver-face instrument pack assemblies are catalogued for MG TF variants, six complete packs covering manual non-TF160, TF 160 manual, and automatic specifications in both MPH and KPH, for owners preferring a single-part replacement over swapping individual gauges into an existing housing. The coolant temperature gauge should be monitored carefully on these cars: the mid-engine cooling system's long pipe runs mean a rising gauge can indicate developing trouble before catastrophic failure, and intervention at the first sign of temperature rise is always cheaper than intervention after boil-over.
Cowl Assembly, Case, Circuit Boards and Brackets
The cowl assembly is the binnacle housing that surrounds the cluster and sits directly in the driver's line of sight. Three cowl variants are catalogued in black PMP finish: MGF non-VVC to XD511058, MGF VVC to XD511058, and a common cowl for MGF from XD511059 and all MG TF. Inside the cowl, the illuminated case and instrument case assemblies are catalogued separately, each era with its own printed circuit board, pre-XD511058 cars use different PCBs for MPH versus KPH and for non-VVC versus VVC (four PCB variants total), reflecting the warning lamp differences associated with VVC-specific fault reporting. Post-XD511059 cars use a common PCB.
Handed LH and RH mounting brackets carry the cluster in the dashboard, along with M4 and self-tapping screws.
Bulbs and Illumination
Cluster illumination uses several bulb types. The 1.4-watt bulb is the main illumination item, used in quantities of 8 to 10 depending on era. A blue 2-watt bulb covers the main-beam indicator, and 1.12-watt grey bulbs cover specific warning functions. The silver-face era introduced a single LED bulb and holder for an indicator that was found to be prone to incandescent-bulb failure.
When removing the cluster for bulb replacement, the bulb holders twist out from behind, the cluster does not need complete dismantling for this straightforward service task. Stepper motor failure, producing stuck or erratic needle movement on one or more gauges, is repairable by instrument specialists as an alternative to complete cluster replacement, which typically costs substantially more.
