Vacuum system diagnostics in Sumy
- Price
- from 500 UAH
We agree the cost with you before any work starts.
Engine vacuum operates many components: the brake booster, EGR valve, turbo and intake flaps. A cracked hose or faulty valve causes unstable idle, mixture faults and weak pulling power. We check the system for leaks and find exactly where the vacuum is being lost, and the repair cost is agreed before any work starts.
Scope
What’s included
- Leak check of the vacuum system and intake
- Inspection of vacuum hoses, lines and connections

Frequently asked questions
Is it dangerous to drive with a vacuum leak?
If the brake pedal has become hard — yes, braking distance increases, so don’t put it off. In other cases you can usually drive to the workshop, but the engine isn’t running as it should.
How is this different from computer diagnostics?
A scanner shows that there is an air leak or a boost problem, but not where exactly. Here we find the specific leak.
Do I need to book?
Yes, preferably — that way we set aside enough time for the search.
