Technical characteristics of the 1.8 TSI engine (EA888 Gen.1) for the Škoda Superb A7

Engine 1.8 TSI (index CDAA or CDAB) belongs to the first generation of the family EA888 and installed on Škoda Superb A7 from 2008 to 2015. This four-cylinder turbocharged petrol engine with direct fuel injection, which became the answer VW Group to the growing demand for economical yet powerful engines.

Main parameters:

  • 🔧 Volume: 1.798 cm³
  • 💨 Turbine: BorgWarner KP35 (on earlier versions) or IHI IS20 (after facelift 2013)
  • ⚡ Power: 160 hp (118 kW) at 4500–6200 rpm
  • 🌀 Torque: 250 Nm at 1500–4500 rpm
  • ⛽ Fuel consumption (combined cycle): 7.2–8.1 l/100 km (depending on gearbox)
  • 🔄 Transmission: 6-speed DSG-6 (DQ250) or 6-speed mechanics (MQ350)

The special feature of this motor is combined injection system: fuel is supplied directly to the cylinders (FSI), and into the intake manifold (MPI). This solution reduced fuel consumption and improved environmental performance, but at the same time complicated the design. For example, dual injection requires more frequent injector cleaningthan the classic ones TSI second generation.

If you buy Superb A7 with mileage, be sure to check the service history - especially timing chain replacement. On motors EA888 Gen.1 it can stretch after 100–120 thousand km, which leads to engine malfunctions.

Weaknesses and typical problems of the 1.8 TSI on the Škoda Superb A7

Despite the reliability by the standards VW Group, engine 1.8 TSI has several "diseases", which appear with runs over 100 thousand km. Here are the most common:

  1. Timing chain stretch. The problem is typical for all engines of the family EA888 Gen.1. Signs: metallic knocking on a cold engine, floating speed, error P0016 (camshaft misalignment). Solution: replacement of chains, tensioners and shoes (cost of work - from 30 thousand rubles).
  2. Oily appetite. After 150 thousand km, the engine may begin to “eat” oil (up to 1 liter per 1000 km). Culprits: worn oil rings or stuck piston rings. Solution: decarbonization or major repairs.
  3. Problems with the turbine. Turbine BorgWarner KP35 on early versions it is prone to oil leakage through the seals. Signs: blue smoke from the exhaust, loss of power. Solution: replacement of the turbine (from 50 thousand rubles) or repair with replacement of the cartridge.
  4. Malfunctions of the injection system. Injectors FSI become clogged with deposits, which leads to uneven engine operation. Signs: tripping, errors P0300–P0304. Solution: ultrasonic cleaning (from 10 thousand rubles per set).
  5. Overheating and thermostat problems. On Superb A7 The thermostat often fails, which leads to overheating or, conversely, a long warm-up of the engine. Solution: replacement of the thermostat (from 8 thousand rubles).

Deserves special attention gearbox DSG-6. Paired with 1.8 TSI it often jerks when switching, especially on runs over 120 thousand km. This is due to wear of clutches and mechatronics. Solution: changing the oil in DSG every 60 thousand km (officially - “for the entire service life”, but this is marketing).

📊 What is the mileage of your Škoda Superb A7 with 1.8 TSI?
  • Less than 100 thousand km

Owner reviews: pros and cons of the 1.8 TSI in practice

To form an objective opinion about the engine, we analyzed reviews from owners Škoda Superb A7 on the forums (Drive2, Skoda-Club, Drom). Here's what they note:

Pros Cons
🚀 Acceleration dynamics: 0–100 km/h in 8.5–9.0 sec (s DSG). 🛢️ Oily appetite: after 150 thousand km, oil consumption can reach 1 l/1000 km.
⛽ Economical: actual highway consumption is 6.5–7.0 l/100 km. 🔧 Expensive repairs: Replacing a turbine or timing chain costs 50+ thousand rubles.
🎵 Quiet operation: vibrations and noise are less than diesel versions. ⚠️ Fuel Sensitivity: bad gasoline quickly kills injectors.
🔄 Reliable box DSG: with timely maintenance, it runs 200+ thousand km. 🔥 Overheating: weak point - thermostat and pump (change every 100 thousand km).

Fun fact: the owners Superb A7 with 1.8 TSI they often complain about problems with electronics (for example, glitches of the on-board computer or throttle position sensor) than about mechanical breakdowns. This is due to complex engine control system, which is sensitive to power surges and low-quality spare parts.

⚠️ Attention: If you buy Superb A7 with mileage, be sure to check the history VIN on the website Škoda. Motors 1.8 TSI, manufactured before 2012, are more likely to suffer from timing chain problems than later versions.

Maintenance and operating recommendations

To extend engine life 1.8 TSI, follow these rules:

Change the oil every 10–12 thousand km (use 5W-30 or 5W-40 according to VW 502.00/505.00)|Check the oil level once a month (especially after 150 thousand km)|Change the timing chain and tensioners every 120–150 thousand km|Clean the injectors FSI every 60–80 thousand km|Flush the cooling system every 2 years-->

Pay special attention choice of oil. For 1.8 TSI It is critical to use only original or certified oils (for example, Castrol Edge 5W-30, Liqui Moly Top Tec 4200). Cheap analogues lead to coking of rings and accelerated wear of the turbine.

Also don't forget about:

  • 🔥 Spark plugs: change every 30-40 thousand km (original - NGK PFR7S8EG or Bosch FR7DPX).
  • 💧 Antifreeze: complete replacement every 5 years (use VW G12++ or G13).
  • 🔋 Battery: on Superb A7 with 1.8 TSI a capacity of at least 70 Ah is recommended (for example, Varta Silver Dynamic E44).
What happens if you don't change the timing chain?

If the chain breaks or is strongly stretched, the pistons hit the valves, which leads to bending of the valves and major engine overhaul (cost - from 200 thousand rubles). On EA888 Gen.1 this happens more often than on newer engines due to the design features of the tensioners.

Tuning and modifications: how to increase the power of the 1.8 TSI

Engine 1.8 TSI has good tuning potential. Without major modifications you can get 190–210 hp, and with replacement of the turbine and piston - up to 250+ hp. Here are the main directions:

  1. Chip tuning (Stage 1). ECU firmware for euro+gasoline (for example, from Revo or APR) gives +20–30 hp. no mechanical changes. Cost: 15–25 thousand rubles.
  2. Turbine replacement (Stage 2). Installation IHI IS20 or Garrett GT22 allows you to increase power to 220–240 hp. The intercooler and exhaust will also need to be replaced. Cost: 100–150 thousand rubles.
  3. Piston reinforcement (Stage 3). For power above 250 hp. Forged pistons, connecting rods and block boring are needed. This is already “deep” tuning with a budget of 300 thousand rubles.

Important: after any tuning necessarily strengthen the braking system (for example, install brakes from Superb RS or Audi S4) and update the suspension. Also note that The engine warranty will be reset, and the resource will be reduced by 20–30%.

💡

Chip tuning for 1.8 TSI without upgrading the turbine and intercooler leads to engine overheating and a reduction in turbine life by 30–50%.
