If there are problems with Mercedes, and other service stations cannot even diagnose the cause, then you need to contact these guys. They specialize in mercs, they know them inside and out. Repairs are always carried out promptly and efficiently. And just nice and tactful people in communication. I recommend it to everyone.
Mercedes, Iveco, Ford beads will be repaired. All kinds of jobs, good motorists and diagnosticians. For passenger cars, powerful Mercedes specialists. The latest diagnostic equipment, and there is no bureaucracy, as in some newfangled "services in a beautiful wrapper"
