You have a ticking time bomb under the hood!
Reduced engine oil pressure is used in all Volkswagen Touareg and Audi A4, A5, A6, A7, A8, Q5, Q7, Q8 with 3.0 TDI V6 EA897evo generation engines.
The problem affects hundreds of thousands of Audis and Volkswagens produced after 2013.
It was not until March 2020 that the VW group changed the engine settings by raising the oil pressure.
Unfortunately, ecology won over common sense, and the oil pressure in cars after 2020 is still too low. In our opinion, the oil pressure should be increased much more than the VW programmers have done.
Besides low oil pressure, dilution of oil with fuel can also be a cause of engine seizure.
The reduction of oil pressure at low engine speeds was intended to decrease the energy required to generate this pressure. The way to reduce the power needed to drive the oil pump is by using a pump with adjustable output controlled by the engine computer.
Less energy consumed by the oil pump was supposed to translate into improved emissions.
This entire solution was introduced to meet the EURO 6 emission standards.
It works like this: the engine control computer receives data from the sensor measuring oil pressure and then controls a solenoid valve to achieve values consistent with those recorded in the map, which specifies oil pressure based on its temperature and engine speed.
This is probably self-explanatory.
Volkswagens and Audis 3.0 TDI equipped with a variable output oil pump, in which engines seized after tens of thousands of kilometers, come to our service!
Engines in these vehicles are often so severely seized that repairing them is not cost-effective.
Check if your car has such an engine. Read the engine code from the sticker.
If you have the EA897evo engine and no one has previously adjusted the oil pressure settings, your engine is certainly at risk of seizure due to too low oil pressure.
Check what the oil pressure is in your engine.
You can read this with any diagnostic tester.
Raising the oil pressure is done while you wait (it takes about half an hour).
The above video shows how we do it.
By raising the oil pressure, you will save your engine from seizure and huge repair costs.
The horizontal axis represents the engine speed in revolutions per minute.
On the vertical axis is the oil pressure (for simplicity, I provide it in Bars and after subtracting atmospheric pressure)
If you have a car manufactured between 2014 and 2021 and no one has previously adjusted the oil pressure settings, the oil pressure in your engine will rise according to the red line shown in this chart.
The orange line represents the pressure readings in cars produced after 2021.
The green line represents the pressure readings in cars after our software modification.
