Is your Freelander not idling nicely? Poor idling is generally caused by a mixture of problems. Here are the things you should be checking: 1. Check the Idle Air Control Valve (IAC). The position of the IAC is calculated from the readings of many sensors – the Coolant temperature, Air temperature, MAP/MAF sensor, O2 sensor, […]
Do you have a leak from your Freelander? Are you finding it difficult to identify what type of fluid is leaking? Engine oil is usually brown or amber. The older it gets, the blacker it seems to turn. If you see a blackish fluid under your vehicle, it’s likely to be engine oil. Engine oil […]
If your MAF (mass air flow sensor) is faulty and you see a significant improvement when you disconnect the MAF why can you not just leave it disconnected? Disconnecting the MAF forces your ECU to use a default MAF value. This may result in a much more responsive engine if the MAF is faulty however, […]
Does your Freelander 1 TD4 appear to be over or under fuelling? Does it not seem to have the power, fuel economy or smoothness that it used to? You may have a problem with your MAF sensor (the original sensors are Bosch sensors). To test this, unplug the MAF and see if things improve. If […]
Does your Freelander 1 TD4 have turbo lag? This can be made worse by the EGR (Exhaust Gas Recirculation) valve being clogged up. The EGR valve is there to reduce emissions. However, on the Freelander TD4 the vacuum valve, which controls the rate at which exhaust gases enter the intake, obstructs the intake airflow by […]
Do you understand oil viscosity? Most oils nowadays are a multigrade, such as SAE 10W40, which simply means they fall into two viscosity grades. (Multigrades were developed about 50 years ago to avoid you having to use thinner oil in winter and thicker oil in summer). SAE = Society of Automotive Engineers.The SAE designation describes […]
Have you ever put petrol in your diesel Freelander? Diesel is a lubricant and petrol in diesel acts as a solvent, reducing lubrication. This means a petrol / diesel mix can cause damage to the fuel pumps through metal to metal contact – giving you metal particles in the fuel canister, as seen in the […]
Ever wondered when a cut in a tyre will be considered an MOT failure? If the cord is visible then it is automatically a fail for the MOT. If, however, the cord is not visible then it depends how big the cut is. If it is less than 25mm long or 10% of the section […]
Have you replaced an ABS sensor and found the warning light is still illuminated, even after resetting the code? This is because the ABS sensor will not generate a reading until the Freelander is travelling between 2-5 mph. So to get the new sensor to register the wheel will need to be spun by hand. […]
Causes of Brake Noise: Low frequency vibration: Judder Low frequency vibration is a deep noise and is often described as judder. Common reasons for this kind of noise are poor fitment of the disc brake onto the hub, “runout”, excessive disc thickness variation or general disc damage. Medium frequency vibration: Squeal Medium frequency vibrations […]
