Characteristics of the 2.0 TSI CAWA engine
The 2.0 TSI CAWA engine was produced by Volkswagen between 2008 and 2010. This engine is part of the EA888 family and is characterized by high reliability and performance. The main characteristics include an in-line layout with four cylinders and four valves per cylinder.
Cylinder block material
The engine’s cylinder block is made of cast iron for a strong and durable design. The power system utilizes direct fuel injection, which promotes more efficient combustion and improves overall engine economy.
Dimensions and Parameters
The piston stroke is 92.8 mm and the cylinder diameter is 82.5 mm. The compression ratio is 9.6, which strikes an optimal balance between power and economy. The engine displacement is 1984 cubic centimeters.
Power and torque
Engine power varies depending on the modification: 170 horsepower at 4,300-6,000 rpm and 200 horsepower at 5,100-6,000 rpm. Torque is also the same for both versions and is 280 Nm at 1700-5000 rpm.
Fuel and oil consumption
Fuel consumption for the Volkswagen Tiguan with the 2.0 TSI CAWA engine is 13.5 l/100 km in urban conditions, 7.7 l/100 km on the highway and 9.9 l/100 km in the mixed cycle. Oil consumption can reach up to 500 grams per 1000 km of mileage. It is recommended to use oils with viscosity 0W-30, 0W-40, 5W-30 or 5W-40. The volume of oil in the engine is 4.6 liters. The oil is changed every 15000 km, although for maximum life it is better to change it every 7500 km.
Resource and tuning
According to the factory, the engine resource is not specified, but in practice it is 250-300 thousand kilometers with proper care and timely maintenance. The engine has a great potential for tuning, and with the right approach its power can be increased up to 350+ horsepower without significant reduction of resource. However, it is recommended to increase the output to around 250 horsepower without loss of life.
Installation on vehicles
The 2.0 TSI CAWA engine has been installed in a wide range of Volkswagen, Audi and Skoda vehicles, including the Volkswagen Golf 5 GTI, Volkswagen Jetta, VW Passat B6, VW Passat CC, VW Tiguan, Audi A3, Audi Q3, Skoda Octavia RS, VW Eos, VW New Beetle, VW Scirocco and Audi TT. These cars have benefited from a powerful and reliable engine that provides excellent dynamics and high performance.
Reliability and repair of 2.0 TSI engines
In early 2008, Volkswagen 2.0 TSI engines of the same 1st generation were created based on the EA888 1.8 TSI of the 1st generation. These included the CAWA, CAWB, CBFA, CCTA and CCTB motors. They were to replace the past generation 2.0 TFSI of the EA113 series. It uses a 220 mm high cast iron cylinder block with a 92.8 mm stroke crankshaft, 144 mm long connecting rods, 29.6 mm high pistons and a compression ratio of 9.6. The result was 2 liters of displacement.
On top is a 2-shaft 16-valve head made of aluminum. The intake valves are 34mm in diameter, the exhaust valves are 28mm and the stem diameter is 6mm. The intake utilizes a variable valve timing system, and the camshafts rotate via a timing chain.
The 2.0 TSI engines use direct fuel injection (homogeneous mixture). This has an intake manifold with swirl flaps and new injectors (compared to the 2.0 TFSI).
The turbine on the 2.0 TSI is KKK K03, boost pressure is 0.6 bar, and everything is controlled by Bosch Motronic MED 17.5 ECU. CAWB and CAWA engines comply with Euro 4 emission standards, and their direct analogs CCTA and CCTB – ULEV 2 and have 2 lambda probes. There was also CBFA, which was an analog of CCTA, but for California, under SULEV standards. It has already 3 lambda probes and secondary air system.
CAWB, CBFA and CCTA engines develop 200 hp at 5100-6000 rpm, 280 Nm of torque at 1700-5000 rpm. CAWA and CCTB engines differ in firmware and have 170 hp at 4300-6000 rpm, 280 Nm of torque at 1700-5000 rpm.
The 2.0 TSI 1st generation was produced until 2010, but it was gradually replaced by the 2.0 TSI 2nd generation from mid-2008. Despite this, in North America even today you can buy an Audi Q3 with a CCTA engine.
Disadvantages, breakdowns and problems of the CAWA
- The weak point of this motor is the timing chain, it is pulled out already by 100,000 km
- The oil separator also clogs very quickly, which leads to the consumption of lubricant
- Pistons often crack from detonation, but there are alternatives forged
- The cause of floating engine speeds is usually carbon deposits on the intake valves
- The intake manifold swirl flaps also become fouled and then seize up
- If you wait too long to replace the plugs, you will have to spend money on ignition coils
Tuning of engines 2.0 TSI CAWA
Chip tuning
Want to make 260 horses? Go to any tuning office, you will make a firmware Stage 1 and only this will give +60 hp. To use the potential of the motor more effectively, buy a catless exhaust, APR intake, S3 intercooler and fill the firmware Stage 2. This will give the motor a chance to breathe on full, and it will be able to develop up to 280-290 hp, and torque will reach 450-470 Nm, depending on the specific company and under what gasoline the motor is configured.
This is the optimal configuration for active driving, but if you are not enough such figures, then there are turbo kits based on K04, where everything is put from S3: turbine, intercooler, injectors. Also buy APR intake, NGK BKR8EIX plugs, full exhaust on 76 mm pipe and it will be left to flash the control unit. This will give up to 370hp, over 550Nm of torque and very serious dynamics. Building 2.0 TSI on the turbine K04 is included in the list of standard services of many tuning organizations, all this has long been worked out and tested.
Even more can be obtained with a turbo kit based on Garrett GTX2867R, such a turbine has no problem inflating up to 450 hp, depending on fuel and tuning.
