My oil sensor started blinking while I am driving. I stoped and added oil to the car because the level was in low level. Went to the dealership to check my car in if I do have leakage or if my engine did start to burn oil. They did suggest to come visit them after 600 miles which I did. And after check up they did end up saying yes your car did burn oil around 0.25 quart. And I suggest you to come after 600 miles again. I need that issue to be fixed and they are wasting my time in this unnecessary procedure. It was confirmed that my engine burn oil and I have got extended warranty plus my car was always been serviced by the vw dealership.
I received a check engine light and my mechanic diagnosed the problem and attributed it to an the air pump control valve which was connected to primary engine water pump. A slight leak in the air system was noticed since the check valve failed. The primary engine water pump began to lose pressure over time causing increased tail pipe emissions. I tried to report this issue to VW but fell on deaf years. Since the primary engine water pump was part of a recall i was explaining that the air pump control valve also had to be replaced because the open/close relay stopped working. I spent 820 $ parts + labor to get this fixed and VW does not even want to accept it as a problem. I have been constantly encountering these problems with my VW car. This is a safety issue and hence wanted to report this to NHTSA.
Intake Manifold Runner is failing. This could suddenly put the vehicle in limp mode on the open highways, resulting in a hazardous situation due to sudden slowing. MIL light is illuminating and diagnostics from Meineke Car Care Center confirms failure of the Intake Manifold Runner. Similar issues have been noted with past VW models, with Intake Manifold warranty extension to 10 years, 120,000 miles for 2006-2008, 2008-2012, and 2013-2017 model years. It seems the problem continues through 2018 as I reached 90,000 miles with a failure. Volkswagen service specialists was quoted as "that sounds about right" so the problem clearly lingers for the 2018 model years and beyond.
Intermittent stalling. Typically at stop, when vehicle has been running a short time. Vehicle restarts. Occurs frequently, every week, but not every trip. Started in spring 2021, recurring issue. Mechanic unable to replicate.
MY CAR IS UNDER 7000 MILES, DON'T EVEN HAVE THE FIRST SCHEDULE OIL CHANGE AND EXPERIENCE EXCESSIVE OIL CONSUMPTION. I HAVE TAKEN IT TO THE CAR DEALER AND JUST TOP OFF THE OIL. SOMETHING IS WRONG WITH THE ENGINE.
