Having a car in property is an important cost, because of the insurance payments, usual maintenance -wheels, oil, etc …- or the money that disappears in fuel, we must add the breakdowns that originate. Therefore, it is essential that you know what elements you should ‘pamper’ especially your vehicle to try to avoid some of the most common.

But what are the most expensive repairs? According to the opinion of our mechanical department of Sanchez i Morello, the faults in the timing belt, the injectors or the turbo are postulated as repairs more

expensive , whose price starts at 1,000 euros and can reach 5,000 euros, depending on the vehicle.

Turbo: In this case, the repair is an outlay for the customer between 1,000 and 5,000 euros, depending on the brand and model of the car. This piece is responsible for granting that extra power to your car, and does so by injecting air at high pressure into the engine thanks to a turbine.

How to take care of it? Avoid cold accelerations – even more in a vacuum – and, if you can, wait a couple of minutes with the engine running when you finish your route to lower the temperature before turning it off.


Injectors: In this case, the problems are usually caused by its use and sometimes by the poor quality of the fuel or dirt chips lodged in the circuit, which causes its obstruction. Its repair translates into a payment of 2,000 euros.

Preventing this is more complex since in most cases its deterioration responds to mere wear.

The timing belt: can range between 250 euros and 2,000, making it the third most expensive car when it comes to repair. Its function is to synchronize the movement of valves, pistons, camshafts and sprockets that make possible the operation of the engine.

To avoid breaking, it is advisable to follow the recommendations that the manufacturer reflects in the maintenance book and change it when indicated. Usually, its duration ranges between 80,000 and 130,000 kilometers or five years, depending on the brand.


Engine control module: is responsible for managing all the information of the sensors and actuators of an engine in both diesel and gasoline. The fault can be produced by a general failure in the voltage of the vehicle, as well as a general failure of an independent system, which can involve an outlay of between 650 euros and 2,500 euros.

Avoid exposing the car to high temperatures or humidity to favor its good condition.

Gearbox: </ strong> is less frequent, but can also break. It usually happens due to neglecting the maintenance of the vehicle or due to bad practice when changing gears. The cost of repair or replacement of damaged items ranges between 1,000 and 3,000 euros,

To keep it in good condition it is essential to change gears without ‘scratching’, as well as not to rest your hand on the lever to avoid friction with other elements as a result of weight.

The figures presented are approximate but they do account for the high cost in this type of repair.
