VW/Audi 1.8 TSI/TFSI EA888 Gen 1/2/3 Engine Specs, Problems, Reliability. The 1.8 TSI/ TFSI engine of the EA888 family was made as well as established by AUDI AG and introduced in 2007. It is a 1.8-liter four-cylinder gas turbocharged engine with direct fuel shot. The EA888 1.8 TSI as well as 2.0 TSI engines replaced the EA113 collection 1.8-liter and also 2.0-liter engines. The 1.8 TSI EA888 is continually refined as well as currently has actually 3 generation described listed below.

1.8 TSI EA888 Gen1
The 1.8 TSI Gen 1 by Volkswagen’s codes BYT and also BZB was a substitute for the 2.0 TSI EA113 engine. This engine was created from scratch; the 88 mm (3.46 in) cylinder spacing is the only usual function with the precursor.
The engine is built around a grey cast iron cylinder block as well as crankcase. This is the strong and also reputable material which also has good acoustic moistening properties. For vibration decrease, the crankcase was geared up with two chain-driven counter-rotating balance shafts. The engine block height is 220 mm currently. The engine got steel crankshaft with 8 weights, brand-new light weight aluminum alloy pistons, and also 148 mm long linking poles. The 1.8 TSI Gen 1 has an aluminum 16-valve cylinder head with chain-driven double overhanging camshafts.
The intake camshaft has a variable intake shutoff timing adjustment system. There are 4 shutoffs per cyndrical tube (2 intake as well as two exhaust shutoffs). The consumption valve size is the 34.0 mm; the exhaust shutoff diameter – 28.0 mm; stem size for both valves is 6 mm. The shutoffs are actuated by low-friction roller finger webcam followers equipped with automatic hydraulic shutoff clearance compensation.
The engine has a variable length intake manifold made of plastic as well as BorgWarner KKK K03 water-cooled turbocharger incorporated right into actors iron exhaust manifold. The turbocharger offers limit pressure of 0.6 bar (8.7 psi). The fuel is supplied by a straight fuel injection system with sequential solenoid-controlled six-hole fuel injectors. The ECU for 1.8 TSI EA888 Gen1 is Bosch Motronic MED 17.5. The 1.8 TFSI engines for Audi applications (CABA, CABB, as well as CABD engines) feature the Gas Stratified Shot (FSI) system and also variable oil pump. The first generation of 1.8 TSI EA888 was generated up until 2010, however the 2nd generation showed up currently in 2008 (a year later after Gen1 was launched).
1.8 TSI EA888 Gen2
The designers quickly made deal with bugs and also launched the second generation in 2008. The Gen 2 of the 1.8 TSI engine for a long time was produced together with Gen1, however the Gen2 became one of the most widespread variation. It has the following engine codes: CDHB, cdha, as well as cdaa. The engine got the new steel crankshaft with the decreased diameter of the major journals (from 58 mm to 52 mm). There are brand-new pistons as well as piston rings triggered the major trouble with high oil consumption. All engines now are equipped with the variable oil pump. In the remainder, it is the same Gen1 engine with minor modifications in small details and also ECU tuning. The production of 1.8 TSI Gen3 continued up until 2015.
1.8 TSI EA888 Gen3
The 1.8 TSI EA888/3 or Gen 3 was released in 2011. This engine was offered at first for Audi cars and also later on for other brands of VW Team. The 3rd generation is a deeply redeveloped previous generation as well as virtually the new 1.8-liter engine in the EA888 household.
The engine has a brand-new light-weight cyndrical tube block with thin wall surfaces. The new long lasting and light crankshaft now has just 4 weights. The pistons and also attaching poles also were upgraded. The most obvious distinction is the new cylinder head. It is a 16-valve aluminum DOHC cyndrical tube head with an integrated exhaust manifold. Both camshafts include variable valve timing system. Along with that, there is a two-stage shutoff lift control changed after 3,100 rpm. The timing chain stays untouched, yet the chain tensioner was replaced with a new one. The gas system consists of the combination of the direct gas shot inside burning chambers and also traditional multipoint gas injection prior to the intake valves. The 1.8 TSI EA888/3 is outfitted with IHI IS12 turbocharger. The max increase stress of the brand-new system is 1.3 bar (18.8 psi).
The auto version with longitudinal engine area has the following engine codes – CJEB, CJEE, CJED; CJSA is a transverse engine. Four-wheel drive lorries usually have the CJSB engine version. The most typical 1.8 TSI Gen3 engines for the North American market are CPKA and CPRA.

VW/Audi 1.8 TSI/TFSI EA888 Gen 1/2/3 Engine Problems and Reliability
The Gen 1, 2 and also Gen 3 have the problems with a stretched out timing chain. It typically takes place nearly after 60,000 miles (100,000 kilometres). The issue is accompanied by a high engine noise and also unstable operation and can lead to severe engine problems. The Gen3 has a new tensioner and these engines are less vulnerable to such breakdown.
The Gen2 is popular as a result of its love to consume a lot of oil. That usual issue is triggered by too slim piston rings. The oil consumption is very dynamic as well as rises to 2 liters by 1,000 kilometres at gas mileage around 100,000 km (60,000 miles). The solution is changing the stock Gen2 pistons by pistons and piston rings from the Gen1 engine. The Gen1 as well as Gen3 don’t have that concern in troubles checklist.
Approximately on the mileage ranges of about 100,000 km (60,000 miles) or earlier, the modification of the turbocharger actuator is required for Gen3 engines.
The straight shot engine has an inescapable problems with carbon build up on the intake ports and the consumption shutoffs. The gas is included directly right into the cylinder as opposed to injected right into the port and rinsed carbon down payment. That leads to limited airflow, extra weight on shutoffs as well as poor closing gaps. The engine will create much less power and take in even more gas. The Gen3 engines have fuel injection right into the ports along with the direct injection; in this situation, the last generation stays away from that issue and keeps the consumption parts reasonably tidy.
Unsteady long life, high oil consumption, timing chain problem made a bad credibility for the 1.8 TSI EA888 amongst automobile proprietors all over the world. Unfortunately, one of the most prominent engine 1.8 TSI Gen2 has identified not just itself however the all 1.8 TSI EA888 family members as undependable engines.
Despite the above problems and problem, these engines are quite excellent. They produced a lot of power as well as torque at the same time takes in much less fuel than rivals. All generations are simple to tune by basic ECU remap (Stage 1). Engines after Phase 2 and also 3 (extra effective exhaust, performance turbocharger, and also ECU upgrade) reveal impressive numbers in power as well as torque. Like all turbocharged engines with direct injection, the 1.8 TSI EA888 engine needs the top quality oil and also gas, appropriate and also regular maintenance. With minimized maintenance periods and a good treatment, the supply Gen1/Gen3 engine life is about 150,000-200,000 miles (250,000-300,000 km); uncertain costly repair service at 60-80k miles for Gen2 engines is very potential.
