BOOST
Turbo System Faults
Underboost & Lost Power
Find split boost hoses, leaking joints, intercooler leaks and pressure loss that can leave the vehicle flat or inconsistent.
Professional smoke testing in Newtownards to find hidden turbo, intake, intercooler and vacuum leaks. Ideal for power loss, underboost faults, poor response, excess smoke and vehicles where parts have already been guessed at.
Find split boost hoses, leaking joints, intercooler leaks and pressure loss that can leave the vehicle flat or inconsistent.
Smoke testing makes hidden air leaks visible, helping confirm the fault before time and money are wasted on parts.
Vacuum leaks can affect boost control, idle quality, actuator operation and general drivability.
Small leaks can cause big symptoms. A split hose, loose clamp, cracked intercooler, failed seal or vacuum leak may not be obvious during a normal visual inspection, but it can still trigger faults and ruin how the vehicle drives.
We connect diagnostic smoke equipment to the relevant system so leaks show themselves quickly and clearly.
A controlled smoke test gives a clear fault-finding route instead of replacing sensors, valves and pipework blindly.
We look at the symptoms, fault codes and system being tested so the correct area is checked first.
Smoke testing equipment is connected to the intake, boost or vacuum system depending on the fault path.
Controlled smoke is introduced so escaping smoke shows the leak point clearly.
Once the fault is found, we explain the issue and advise the next correct repair route.

Yes. Smoke testing is one of the best ways to find leaks in boost hoses, intercoolers, pipework and air system joints that can cause underboost faults.
Yes. Vacuum lines and control circuits can be checked where access and system design allow, helping diagnose boost control and drivability issues.
No. It identifies the leak or helps rule leaks out. Any repair work, parts or follow-up diagnostics are separate.
Yes. The workshop is based in Newtownards and serves customers from Bangor, Comber, Belfast, County Down and wider Northern Ireland.
