After we had completed our Golf 5 TFSI (Audi A3 8P) project to a large extent, we continued of course with the next engine concept:
The EA888 series is the first 4 cylinder chain engine. So VW used a chain drive instead of a timing belt for the engine control. Especially the engine block was completely revised and reinforced. The EA888 is considered the second T(F)SI generation. Further information with the exact differences can be found HERE.
Unfortunately, the timing chain is also one of the biggest weaknesses of this engine concept. The picture on the right shows a timing chain after approx. 160,000 km. In comparison to a new chain you can clearly see the difference in length! The status of the control times and thus the already advanced elongation can be checked with VCDS while the engine is running. Measured value block 93 shows the phase position between the sensors crankshaft and camshaft. A value of 0° is ideal. It becomes critical from minus 3°. If no VCDS is available, you can also check the extended path of the chain tensioner. There is a round rubber plug in the front cover. If this is removed, you can see the chain tensioner and its already extended path. From 3 links we recommend the exchange of the entire chain drive. Unfortunately also the engine control light does not warn in time of a too strong chain elongation. If in doubt, simply have it checked in the workshop before engine damage can occur!

Stage 1 completed: 288 PS (212 kW) speak for themselves! Only changes so far: Change of chain and BAR-TEK® GTX Racing oil, Turbooutlet with our TÜV approved boost pressure tubes, nozzles cleaned incl. BEDI cleaning, RACE spark plugs with high performance coils and our carbon air intake. Final then tuned with only 1 bar boost pressure on our calibrated MAHA dyno.
More infos also in our 2.0L TSI Tuning Guide.
Stage 2 completed: In addition to stage 1 we installed a 3" downpipe, turbooutlet with our TÜV tested boost pipes and an exhaust system from catalytic converter with TÜV. The software was also modified.
More info can be found in our tuning guide.
Stage 3 completed: Strong 350 PS (257 kW) speak for themselves! At stage 3 the following parts were installed: an Upgrade Turbocharger Kit V1 and a Race Intercooler with TÜV. After these modifications, the software was adjusted for the new components to achieve the maximum performance.
Additionally the DSG software has to be adapted. With a manual transmission should be installed an upgrade clutch kit.

Here is a comparison between level 2 and level 3!
