MG TF problems (2002–2011)

The only engine of the MG TF that we have documented, the Rover K-Series, has high or critical severity faults in the versions it is fitted to. Our verdict for the versions it is fitted to: «With caution».[1][2][3][4]

Outside the engine: Outside the engine, Parkers mainly flags rust in the underbody, roof, electrics and suspension knocks. These are typical faults for a 2002-2011 car, not serious problems; the TF's big weak point is the engine's cylinder head gasket, which is not covered here.[5]

MG TF rating: acceptable reliability

Calculated using only 8 documented faults and their sources: the most serious and frequent faults weigh more. Limited evidence: it is based on few sources or few documented faults, so it is not included in the rankings. Having few documented faults does not mean it is reliable: it may simply be little studied. How it is calculated

Documented engine

The first label is the most serious fault affecting that engine in this car; the second, our verdict for the versions it is fitted to. Each engine's risk index is calculated only from the faults that affect this car (how we calculate it).

Verdict for the versions it uses

  • 1.6 16V 109-116 hp (16K4F, 1995-2005)1995–2005 · 109–116 hp · 16K4F

    With caution

    This is one of the versions where technical sources place the change to "damp" liners, with less coolant between cylinders; Diariomotor recommends checking whether the gasket is already the reinforced one.[1][2]

  • 1.8 16V 117-136 hp (18K4F, 1995-2005)1995–2005 · 117–136 hp · 18K4F

    With caution

    This is the version most cited in head gasket failures; it is worth buying if it already has the multi-layer (MLS) gasket with the liners measured, and Diariomotor considers its absence a good argument for negotiating the price.[1][2][3]

  • 1.8 VVC 145-160 hp (18K4K, 1995-2005)1995–2005 · 145–160 hp · 18K4K

    With caution

    It shares the 1.8's head gasket problem (suppliers sell specific multi-layer kits for the VVC); we have not found faults specific to the VVC mechanism in open sources.[3][4]

Faults that affect the TF

  1. High severityFrequency: CommonCylinder head and blockHead gasket failureThe K-Series' big problem is the head gasket, which can fail even below 100,000 km because of a mix of gasket design, cooling and overheating. The usual repair uses the multi-layer steel (MLS) gasket that was developed for the Freelander.
  2. High severityFrequency: OccasionalCylinder head and blockSunken cylinder liners and warped head after overheatingAfter overheating, the K-Series liners can end up below the surface of the block and the aluminium head can be marked or warped; then no gasket seals properly and the liner height has to be measured and restored.
  3. Medium severityFrequency: OccasionalCoolingCoolant leaks: expansion tank cap, rear block rail and hosesThe K-Series circuit holds about 5.5 litres, so a slow leak empties the expansion tank and causes localised overheating. The points cited are the tank cap, the metal rail at the rear of the block (corrosion), the hoses and the coolant passages of the inlet manifold gasket.

Frequently asked questions

Is the MG TF reliable?

The only engine of the MG TF that we have documented, the Rover K-Series, has high or critical severity faults in the versions it is fitted to. Our verdict for the versions it is fitted to: «With caution». Outside the engine, Parkers mainly flags rust in the underbody, roof, electrics and suspension knocks. These are typical faults for a 2002-2011 car, not serious problems; the TF's big weak point is the engine's cylinder head gasket, which is not covered here.

What problems does the MG TF have apart from the engine?

Outside the engine, Parkers mainly flags rust in the underbody, roof, electrics and suspension knocks. These are typical faults for a 2002-2011 car, not serious problems; the TF's big weak point is the engine's cylinder head gasket, which is not covered here. The most important documented faults are: rust on the subframe, sills and wheel arches (bodywork and interior, medium severity), plastic rear window and deteriorating hood (bodywork and interior, low severity), electric windows, central locking and hood wiring (electrical system, low severity) and suspension knocks from shock absorbers and bushes (suspension, low severity).[5]

What faults does the MG TF have?

The most important by severity and frequency, on the engines we have documented, are: head gasket failure (Rover K-Series, high severity), sunken cylinder liners and warped head after overheating (Rover K-Series, high severity) and coolant leaks: expansion tank cap, rear block rail and hoses (Rover K-Series, medium severity).

What is the best year to buy a MG TF?

According to our rating by year, the best are 2011, 2010, 2009 and 3 other years with the same rating (8.1/10); the worst rated is 2002 (6.7/10). Each year's rating counts only the engines sold that year and the faults that affect those units: open each year to see what changes.
