BTS Turbo Diagnostic Tool

The BTS Turbo Diagnostic Tool offers the possibility of conducting three easy and quick tests to give you a quick overview of the turbocharger surroundings withouth using the OBD tester. The BTS Turbo Diagnostic Tool was developed to measure the crankcase ventilation pessure, the exhaust backpressure and pneumatic actuators. If there are any problems with the engine charging system, the fault does not always lie with the turbocharger. In a lot of cases, the turbocharger falls victim to other problems in the surroundings. Therefore, the turbocharger surroundings always have to be taken into account in the diagnostic process.

The BTS Turbo Diagnostic Tool is available directly through BTS or your wholesale partner with the following partnumber: MESS01

Tube Level Test

The BTS Tube Level Test enables you to easily measure the crankcase ventilation pressure. The construction is independent from the vehicle manufacturer, therefore, the Tube Level Test can be used on almost all passenger cars. 

Problems with the pressure inside the engine often lead to an oil leakage on the turbocharger. The increased pressure causes a blockage in the oil outlet of the turbocharger. Therefore, the oil cannot flow into the oil pan freely. The oil is thus pressed through the turbocharger and into the exhaust system and / or air inlet system - even if all the sealings are unimpaired. Blocked filters may lead to oil mist reaching the the air inlet of the turbocharger through the exhaust air pipe of the crankcase ventilation.




Measuring Device for Exhaust Backpressure:

A device to measure the exhaust backpressure is also included in the BTS Diagnostic Tool. Too high exhaust back pressure will sooner or later cause problems for the turbocharger and will consequently lead to a failure. 

Increased exhaust backpressure harbors different risks. For example temperatures inside the turbocharger increase, leading to a higher thermal strain and thus increasing the risk of coking oil on the bearings. 

Moreoever, an increased exhaust backpressure will cause an axial thrust on the turbine shaft. This leads to an increased wear on the axial bearing and thus to a bearing damage and / or complete failure of the turbocharger. 

It may also cause oil leakages on the compressor side due to the imbalance of the pressure ratio. A strongly smoking engine and unclean combustion are the consequence.

Checking the pneumatic actuator

You cannot only measue the exhaust back pressure with the BTS measuring device but also check if the pneumatic actuator is working correctly.

You just remove the control pipe from the actuator of the turbocharger and insert a the manometer by using a t-connector. With this method you can check the pressure on the actuator as well as the vacuumpump or the magnetic valve - even when driving.
