These last 30 days we had 4 April 2 0T FSI cars back to back with cam failure to our store While the technicians were working on them, I took a bunch of pictures and wanted to set up a simple writing, to show you guys how this failure happens, what are the consequences, the scale repair and preventive measures.
This failure is not specific for modified cars with fuel pumps aftermarket high pressure or other performance enhancing add ons such as software, exhaust, intake, bigger turbos 2 cars on 4, were completely stock regularly maintained by dealers until their warranty has expired.
Check the low pressure engine light in the fuel rail code.
Very simple handset to normal wear on the cam follower surface and the pressure of the high pressure fuel pump, the surface of the follower to one point in this case, the cam follower has been completely damaged.
It clearly shows the high pressure fuel pump punctured by the cam follower This requires further inspection This is the worst health care in general, we see excessive wear on the cam surface and minor scratches on the tip of the 'intake camshaft that can be easily seen if wear on the cam follower, we recommend a visual inspection of the high pressure fuel pump, cam shaft lobe and replacement of damaged parts.
Back to our particular case is how the high pressure fuel pump like.
As you can see the piston contact area is very worn and follower parts are present between the piston and spring You can kiss goodbye to the high pressure fuel pump replacement is necessary.
Further inspection continues with the shaft lobe intake cam.
The stripes on the tip of the camshaft are obvious is the disturbing part, see the cam-pieces against it.
This image shows here the wear on the lobe of the camshaft and the intake camshaft is outside the cylinder head.
In a serious situation where metal parts are in the engine, there are 3 options.
2 complete disassemble and rebuild with new parts replacing the engine is about the same price.
3 Carefully replace the pieces and try to extract the metal parts of the car.
Option 3 is always the least preferred method, because there is so that the technician can do to flush chips of metal car parts.
This is one reason why we see the failures of the oil pump premature on FSI engines leading to catastrophic engine failures Unfortunately, VW and Audi recognizes the problem, but even in severe cases would guess enough replacement parts to maintain in operational state engine in its estimated life.
We have chosen to give the best of our knowledge to our customers and ask them to make a decision based on their financial situation, and schedule.
Note If the cam follower is not disintegrated, but there is normal wear and tear, it is quite well to replace the parts, followed by motor flushing.
We decided to take a little down work, and removed the oil pan this way, we could see where pieces of metal shavings in the oil pan.
It is not part of the procedure recommended by the factory, but it gives us the opportunity to determine the severity of damage in this case, the car came very quickly after we check engine light was, and began running bad.
Cleaning the engine oil sump picture whole oil pump.
Remove the screen on the oil tube to inspect metal shaving accumulation and clean.
Assembly process is tedious This car was in the city where he needed a timing belt service We proceeded to replace the timing belt, tensioner, idler rollers, serpentine belt and the water pump.
New stretch bolts and all up and down is the factory torque specifications.
Finally, all the fluids are on the vehicle, prepaid codes and Test We invited the customer back after some time for a check, and gave the additional oil change including treatment products oil BG motor After 30 days, the car is running very well.
Simple frequent oil changes and replacement cam follower inspection any other oil change or 10,000 miles, we use specific Motul 502 00 505 00 5W40 oil on FSI engines is a bit more expensive than outside the Castrol or Mobil 1 night, but our customers reports back with less engine noise, smoother operation and less engine burning oil is another case study material on B8 Audi A4s, come.

My 2010 Jetta Turbo 2 0l currently 110,000 miles 109250 A oil pressure light came only in city traffic as 25 mph took to the dealer who did all the work on the car myself Tells metal shavings in oil 475 diagnostic fee plus taxes 8700 But as I was so well told -do include a new turbo Yay I have a lead foot, but follow the interview provided to the letter that I see this problem happens around the same time in several vehicles hummm owners.
Such a shame I had the same problems, and the engine eventually became junk I also made contact with VW and the same thing was said before all the problems, it was by far the best car I ever owned 4 cylinder, turbocharged, 6 shift I was getting 42mpg on the highway in this asshole before everything went south and the leather packing, 6 CD changer and sunroof LOL I felt incredible demolishing road, I returned to GM and pleasant, but it was not as beautiful as my Jetta I hope they do the new models much better.
Am have the same problem too sad for my Passat I grew to love this car very well, I already spend 600 on the fuel pump and follower of the camshaft and now my mechanic told me that I could need a new engine Am very upset with vw.
