Volkswagen 1.8 TSI EA888 Engine Problems and Specs | Engineworks

1.8 TSI EA888 Engine

1.8 TSI/TFSI EA888 motor was first manufactured by Audi AG in 2007. EA888 1.8 TSI plus 2.0 TSI were constructed as alternatives to 1.8 and 2.0L motors from EA113 lineup. Being a 4-cylinder gasoline engine featuring turbocharger and direct fuel injection, this motor was modernized three times. So, let’s find out a bit more about its variations.

1.8 TSI EA888 Gen 1

Serving as a substitute to 2.0 TSI EA113 and being manufactured till 2010, the debut version of 1.8 TSI motor with BYT and BZB codes was built from scratch. Its only identical characteristic with its forerunner remains the 88 mm (3.46 inches) cylinder spacing.

Cylinder block and crankcase are made of grey cast iron, which is high-productive and enduring along with having outstanding acoustic dampening features. To decrease vibration, crankcase comprises 2 chain-driven counter-rotating balance shafts. Having 220 mm block height, 1.8 TSI Generation One gained steel crankshaft with 8 counterbalances, updated aluminum pistons plus connecting rods of 148 mm.

Motor keeps 16-valve cylinder head (having 2 intake and 2 exhaust valves for each cylinder) with chain-driven dual overhead camshafts while intake camshaft features a variable intake valve timing control system. Diameter of intake valve is 34 mm while the exhaust one is 28 mm and stem diameter for both of them is 6 mm. Low-friction roller finger cam followers, containing automatic hydraulic valve clearance compensation, operate valves.

Keeping variable length plastic intake manifold, the debut generation of motors gained BorgWarner KKK K03 turbocharger with water cooling, placed in cast iron exhaust manifold and having maximal boost pressure of 0.6 bar (8.7 psi). Gasoline is supplied via direct fuel injection system, having consistent fuel injectors with 6 holes run by solenoid. Electronic control unit is Bosch Motronic MED 17.5. Simultaneously, 1.8 TFSI motors, applied for Audi cars with CABA, CABB and CABD codes, got Fuel Stratified system along with variable oil pump.

1.8 TSI EA888 Gen 2

As the first generation wasn’t perfect, the brand continued to optimize this engine in 2008 and created TSI EA888 Generation Two, which was produced till 2015. Though this motor was manufactured along with its predecessor for two years, it turned into the most popular modification. With CDAA, CDHA and CDHB codes, motor gained updated steel crankshaft while main journals diameter decreased from 58 mm to 52 mm.

Besides, modernized pistons and piston rings were added, but served as the main reason for excessive oil consumption. Consequently, motors were built with variable oil pumps. But everything else, except some minor elements and Electronic Control Unit tuning, is similar to the 1st generation.

1.8 TSI EA888 Gen 3

Manufacture of the 3rd generation of 1.8 TSI EA888 was launched in 2011. Initially, these motors were utilized for Audi automobiles, but afterwards some other VW Group vehicles were supplied with them. Generation 3 motors appeared after numerous modifications and had a few similarities with the 2nd generation.

1.8 TSI EA888 Generation 3 features fresh lightweight cylinder block with thin walls, light but enduring camshaft with 4 counterbalances, redeveloped pistons plus rods. Upgraded cylinder head is a distinctive feature of motor. Aluminum cylinder head with dual overhead camshaft and 16 valves comprises integrated exhaust manifold. Intake and exhaust valves are operated by variable valve timing system. Additionally, 2-stage valve lift control turns on after 3,100 rpm. While no changes were made to timing chain, another chain tensioner was applied.

Fuel system contains direct fuel injection inside combustion chambers along with classic multipoint fuel injection before intake valves. Motor keeps IHI IS12 turbocharger with the maximum boost pressure of 1.3 bar (18.8 psi).

Motors with CJEB, CJEE and CJED codes are located longitudinally while CJSA is placed transversally. Nine times out of ten, 4-wheel drive automobiles feature CJSB engines. Meanwhile, CPKA and CPRA are the prevalent motors at the American and Canadian market.

VW 1.8 TSI Engine Problems and Reliability

All kinds of 1.8 TSI EA888 face the trouble with timing chain stretching after approximately 60,000 miles (100,000 kilometers) are run. Signs of this malfunction are noise and unsteady functioning while consequences may deal with serious motor breakdown. The 3rd generation keeps another tensioner and has fewer chances for such dysfunction.

Unlike Generation 1 and 3, the 2nd generation tends to have troubles with excessive oil use, induced by thin piston rings. Moreover, with time, motor starts to use more oil. It can consume about 2 liters by 1,000 kilometers after motor run around 100,000 kilometers (60,000 miles). It’s advisable to exchange pistons for the ones of the debut modification.

In Generation Three motors, turbocharger actuator must be regulated after motor runs more than 100,000 kilometers (60,000 miles).

Motors with direct injection often face trouble with charcoal, appearing on intake valves plus intake ports. Fuel gets straight to cylinder instead of being injected into the port and washed out carbon deposit. In consequence of that, airflow is restricted in addition to overloaded valves and inefficient closing gaps. The motor uses more fuel, producing less output. However, Generation 3 engines avoid this trouble thanks to keeping fuel injection into the ports along with direct injection.

On the whole, 1.8 TSI EA888 motors aren’t the most durable and can face many problems, including excessive oil use and timing chain malfunction. Basically, it’s the fault of Generation Two as it’s the most widespread engine of the series.

Nevertheless, motors of this series are pretty reliable. They have great output and torque, consuming less fuel than their rivals. Tuning can be made to all motors through easy Electronic Control Unit remap (Stage 1). After Stage 2 and 3, motors have more effective exhaust, output turbocharger and updated Electronic Control Unit. That leads to outstanding power and torque. Identical to other turbocharged motors with direct injection, this one demands oil and fuel of good quality, periodical and efficient service. If you take care of the motor, it will serve you for 150,000-200,000 miles (250,000-300,000 kilometers) and even more. However, Generation Two may need some adjustments or repairs after 60,000-80,000 miles run.
