Workshop or DIY repair? (Audi A4 B6)

A modern engine is an expensive design, amateurs are unlikely to be able to repair any units and parts of such an engine. Repair and adjustment of the engine in almost all cases should be carried out in a workshop. This requires special knowledge, control and measuring devices and other auxiliary means.

Even an incorrectly replaced timing belt can cause serious damage to pistons and valves. If you are not sure that you can competently carry out work inside the engine, then it is better to refuse to do the repair yourself! It is better to leave the repair of the cylinder head and valves to the workshop, as well as troubleshooting bearings and dismantling the crankshaft. However, there are still a number of works on checking and maintaining the engine that you can do yourself.



Often, it is simply impossible to do without the services of a specialized workshop. The workshop has a VAS 5051 diagnostic, measurement and information system for analyzing complex cases of malfunctions. This system has replaced the VAG 1551 defectoscope, which has been used for several years.
