The BAR-TEK® roller tappet for 2.0L TFSI engines
You're probably familiar with the problem of defective pump tappets on the 2.0L TFSI engine. We didn't want to put up with it anymore and developed a solution: the 2.0L TFSI roller tappet. We managed to drastically reduce the enormous load on the camshaft! Here you can find out what the problem is and how our roller tappet works.
No more need for defective pump tappets with the 2.0L TFSI?
Affected vehicles: all VAG vehicles with 2.0L TFSI EA113 and K03 or K04 turbochargers.
Engine codes: AXX, BGB, BPG, BPJ, BPY, BUL, BWA, BWE, BWT, BYK, BHZ, BYD, BZC, CDLA, CDLB, CDLC, CDLF, CDLG, CDLMA and CDZA.
The problem with the pump tappet
The known problem of the pump tappet is punctual friction and shear force. If the pump tappet is worn, the camshaft is irreparably damaged. The damaged surface must result in a complete replacement of the camshaft. In the worst case, chips can result from this defect and fall into the oil pan. This is where the oil pump and the balance shaft module are located. Any resulting damage to these components will result in major engine damage. In addition, the guide of the pump piston wears out and leakages can occur in the high-pressure pump. If this is the case, fuel enters the oil circuit and the oil loses its lubricating properties. Higher fuel consumption and the smell of fuel in the oil are the first symptoms and can even lead to bearing damage to the connecting rods.
Here's the perfect solution for you so this doesn't happen.
The solution: The roller tappet
We offer you a conversion kit for high-pressure pumps. Here the pump tappet is replaced by a roller tappet. The advantage lies in the fact that the force is better distributed on the ram presses and thus the wear is reduced. The camshaft is protected by lower friction and the improved guidance of the pump piston prevents leaks. For the conversion, the housing is precisely milled and the adapter flange inserted. The spring is replaced by a version with adapted spring rate. The ferrate is important for a smooth flow of the pump mechanics and was also successfully used by us at the 24-hour race at the Nürburgring. You can see what came out of this in our Test-Audi A3.
We also developed a kill kit for your vulnerable intermediate shafts. This kit uses an older but more proven technique. A 1.8T 06A oil pump with a higher flow rate is installed using an adapter plate and chain tensioner.
