MG MGF Common Problems and Solutions

Squealing From Engine

Problem:

When the engine is running, you can hear a high-pitched squealing noise.

Models affected:

Solution:

The alternator’s 8mm adjuster bolt for the auxiliary drive belt is very prone to seizure and can even snap. The squealing sound is coming from the auxiliary belt itself, but you won’t be able to resolve the issue by simply tightening the belt. You’re going to need to remove the engine cover, locate the alternator on the exhaust manifold side of the engine, and unscrew the alternator’s mounting bolts. Remove the alternator and replace the adjuster bolt if it’s broken. You will find the bolts that you need on our parts page for the MGF.

Stuck Handbrake

Problem:

The handbrake is stuck in the on position.

Models affected:

Solution:

Your rear brake callipers have likely seized, usually due to corrosion. Have new callipers delivered when you order directly from our parts list and install the new ones easily.

Stiff Clutch Pedal

Problem:

The clutch pedal is stiff and difficult to engage.

Models affected:

Solution:

It’s likely that you have a seized clutch release arm, which is a fairly common problem for the MGF. You’ll need to remove the gearbox to install the new clutch release arm that you order from BreakerYard, which is quite a challenging job but usually easier than most people think.

Spongy Brake Pedal

Problem:

The brake pedal feels spongy, and the braking time is too long.

Models affected:

Solution:

This could be a case of simply changing your brake fluid, which does need to be done every couple of years. However, a spongy brake pedal can also be a sign that your brake callipers have seized or that you have corroded or worn brake discs. Check your callipers and discs, and order replacements from our parts list as needed. Don’t forget to check your brake pads, as these too may have suffered excessive wear as a result of the above issues.

Not Driving Straight

Problem:

The car drags to one side when you're driving on a straight.

Models affected:

Solution:

If you're lucky, then this will be nothing more than a faulty steering column torque sensor, which you’ll find easily on our parts list. If replacing the sensor doesn’t resolve the issue, then you have a problem with your tracking, which is going to mean a big repair job and some specialist tools.

Rattling Noise From Exhaust

Problem:

You can hear either a rattling sound or a blowing sound coming from the exhaust when the engine is running.

Models affected:

Solution:

The flexible pipe union on the MGF is pretty durable, but it will need to be replaced when it wears out. You'll find the pipe union underneath the engine’s sump, and it’s a fairly easy job to install a replacement. You can order a new pipe union from BreakerYard for quick delivery.

Difficulty level

2

Alarm problem

Problem:

Does your alarm keep going off? The interior protection sensor is the most likely cause. It is usually set to sensitive.

Models affected:

Solution:

You will need to make an adjustment to the interior sensor, in order to de-sensitise the sensor.

3

Cylinder head gasket failure

Problem:

The cylinder head gasket is known for failing on the MGF. The K-Series engines are prone to head gasket failure. If the head gasket fails, it will lead to over-heating. You might also find a white creamy substance underneath the oil filler cap and/or a mixture of oil and water in the water reservoir. Watch the video below:

Models affected:

Solution:

You will need to replace the cylinder head gasket as quickly as possible, so as to avoid any further damage to the engine.

Wet front footwells

Problem:

Have you got wet carpets in the front foot well area? If so, this is most likely caused by a problem with the heater intake box, leaking. This seems to be more of an issue with earlier versions of the MGF.

Models affected:

Solution:

You will need to replace the heater intake box to stop the leak. You will also need to dry out the carpets, so as to avoid any dampness setting in.

Electric window problems

Problem:

Are you having problems with the windows not opening/closing as smoothly as they once did? The MGF is known for having problems with the electric window motor. The teeth on the motors are prone to becoming stripped, causing problems with moving the glass up or down. It seems to mainly affect moving the window up.

Models affected:

Solution:

You will need to fit a replacement electric window motor to fix the problem. However, these can be expensive to replace, but we can help you to find a replacement motor, at a very low price.
