DAF diesels are very popular in the world due to their efficiency and reliability. The basic design requirement is smooth, trouble-free operation, together with low fuel consumption, and a low noise level. The power characteristics of the engines can be chosen according to the area of application.

DAF diesel employs the most advanced production techniques to build its engines. The computer-controlled machining centres serve for production of the engines. All the crucial engine components such as cylinder head, cylinder block, camshaft, connecting rods and valve gear are machined in-house. DAF Diesel is extremely critical of its own quality and it devotes much attention to the smallest details. Its quality standards are very high.

A good reputation can be maintained by paying constant attention to a very high quality level. The same standards apply to components such as fuel injection pumps, and alternators, which DAF obtains from specialized outside suppliers. Every device is tested and inspected before it is found worthy of DAF.

If your car doesn't start, you should check 3 things first: the battery, the fuel level and the spark plugs. It is easy to repair these faults. If the battery is dead, you should recharge it. If this doesn't work, you should replace it. If the petrol tank is empty, fill it up. If the spark plugs are dirty, clean them, and if the gap in the spark plug is too narrow or too wide, adjust it to the correct width. If your car still doesn't start, the petrol pump may be broken or the fuel pump may be blocked. If there is a loud CLICK! when you turn the key, the starter motor may be jammed. In this case you can try to release it by pushing the car forwards and backwards. If the car still doesn't start, the starter motor should be repaired or replaced.
