This year we visited Automechanika Frankfurt 2026 , one of the most important automotive, repair, spare parts and technology exhibitions in Europe. For TECH4S, such exhibitions are not just an opportunity to see the latest technologies or get acquainted with market innovations. They are a place where we meet people and companies with whom we have many years of joint work.
One of such meetings is with our long-time partners DAG .
Our cooperation with DAG began back in 2014. For 12 years, they have been repairing and restoring diesel fuel injection pumps for us, and we do what we do best – repairing heavy equipment diesel engines .
There has been everything over the years. Hundreds of different engines, complex failures, non-standard situations, and cases where simply replacing a part is not enough; you need to understand the entire system and find the real cause of the failure.
That is why it is important for us to have partners whose work we can trust.
DAG has over 30 years of experience in the field of diesel fuel injection systems . Fuel pumps, high-pressure pumps, Common Rail systems and other components of diesel injection systems are their daily work.
We, in turn, have been living in the world of engines for decades. We diagnose, repair and restore engines , search for spare parts and solve technical problems for agricultural, construction, road construction, industrial and other heavy machinery.
Therefore, this partnership works very naturally.
We know engines. DAG knows fuel injection pumps.
And the most important thing for the customer is that they don’t have to look for several different specialists and try to understand where the engine problem ends and the fuel system failure begins. We can assess the problem comprehensively and offer a professional solution from diagnostics to repair.
Why is it important for us to visit partners?
During Automechanika Frankfurt 2026, we not only examined the latest repair equipment, technologies and solutions. We visited our long-standing partners with whom we collaborate every day, even though we are separated by hundreds or even thousands of kilometers.
Emails, orders, and invoices are part of everyday business. However, after many years of collaboration, it feels completely different to be able to meet in person, shake hands, discuss market developments, new technical solutions, and simply chat with people whose work you’ve known for years.
Over the course of 12 years, business relationships naturally become more than orders.
A good partner is someone you can call when you encounter a complex problem. Someone you can consult with. Someone who understands that sometimes you don’t need a standard answer from a catalog, but a real technical solution.
It is this kind of cooperation that we value the most.
Fuel pump repair and engine repair – one system
Engine performance is directly dependent on the condition of the fuel injection system. Difficult starting, lack of power, uneven engine operation, increased fuel consumption or other symptoms do not always mean that the problem lies in the engine itself.
The cause may lie in the fuel pump, high-pressure pump, Common Rail system or other fuel injection components .
Therefore, it is important for us not to guess, but to accurately determine the fault.
In cooperation with specialized partners, we can offer inspection, repair and restoration of diesel fuel pumps , and if necessary, also perform engine diagnostics and repair.
We work with diesel engines and equipment from various manufacturers: Perkins, Deutz, Cummins, John Deere, Iveco, MAN, Fendt, Claas, Case, New Holland, Volvo, Caterpillar and many others.
12 years together
The cooperation, which began in 2014, continues to this day.
Over the years, engines, technologies, fuel injection systems and the market itself have changed. But one thing has remained the same – trust in each other’s work .
We repair engines.
DAG repairs our fuel injection pumps.
And between us – 12 years of experience, shared technical solutions, trust, and friendship.
We are glad that at Automechanika Frankfurt 2026 we had the opportunity to meet again in person, visit our partners, and talk not only about what we do today, but also about what we can do together in the future.
We are proud of our work, but we value the people and companies with whom we can grow year after year just as much.
