I was with my friend at Skoda to make a test drive of new Fabia.
When I opened to see new TSI engine with 5 extra horses (110 total) from prev version I saw this
This is VW Polo but make doesn't matter, it's all VW after all
Did anyone noticed that exhaust side moved to the back to the firewall??? WTF?
May be there is some magic engineering involved, but how it could be better from when it was in front of grill and better cooled with air flow and less heating front cabine part?
Again. Exhaust part (turbine + catalytic converter + pipes) with all high temperature (above 300C) moved to less ventilated part. Let's burn more oil! :-) And more to add, it has AC hoses there not heat protected.
I don't get it... It has programmed potential issues to owners and more profit for garages...
Old setup was much better in terms of logical and physical thinking.
Update (2015-10-21)
I have to note that I talked with owner of SEAT Leon Cupra R after this post.
He also has the same layout with exhaust and turbine near firewall. That's not crappy 1.2 TSI :-) that's 2.0L TSI in stock 265 PS and 340 Nm but now with stage 2 - 335 HP and 450 Nm! No issues. He suggested me that it makes sence in terms of getting exhaust closer to tailpipe, no need to run under the engine block.
Last few month I hear a lot about this VW fuckup. I knew this before but recently a lot of TSI owners bring this up.
If you happen to hear same sound like on video when you cold starting your TSI car, keep reading.
The reason is chain lengthened. As consequences: chain can jump few teeth and valves can meet pistons.
If owner come to dealer with this strange sound, they replace to new improved chain, tension and chain cover with protection from jumping. Even if guarantee is over they do it for free upto 3 or 5 years, I don't remember.
How to avoid it or to delay this issue? Yes, it will happen if your engine was build upto 2011-11-01, see attached TPI below to check your engine serial number if it has upgraded chain set. Always use hand brake when parking! Do not park your car with gearbox only.
Person, who works in VW dealership, advised about these life time of chain:
1.2 TSI - 30'000 km
1.4 TSI - 80'000 km
1.8 TSI - 120'000 km
2.0 TSI - 120'000 km
I can add only that I drove a little more than 30'000 km on my Fabia and I have no issue with it. New owner came yesterday at 53kkm - no issue yet.
Now, I found some assumption that chain condition can be diagnosed with VCDS.
ECU continuously adapting to chain length checking valve open/closed angles. If they exceeds limits - check engine will light up with error "P150D00 chain elongation".
After replacement you should erase adaptation values. There is a message from VAS tool that confirm this: "If the adaptation values are not erased after the timing chain has been replaced and/or worked on, damage to the engine can result. It is absolutely essential that you follow and observe the instructions and notes in the Repair Manual!".
Another interesting information I found that on new 1.2 TSI engines (code CJZB), they will use... toothed belt! :-) VW commented: "replacing the original timing chain mass given argument is that the belt drive is quieter, noise when driving is more quiet."
And we did some research. Params to watch: Address 01 - Engine (J623-CBZB)

Case 1 - Skoda Yeti, 1.2 TSI, DSG
1. Before chain change - angels are huge!
2. After chain change
3. 600km after chain change
Case 2 - Skoda Fabia (Mk2), 1.2 TSI (CBZB), Manual gearbox, 53'301 km
This is mine Fabia, the I did yesterday oil change service for him and we took readings. No rattling, normal values.
Case 3 - Skoda Fabia (Mk2), 1.2 TSI (CBZB), Manual gearbox, 46'606 km.
Friend from Haifa. No rattling, normal values.
Case 4 - Skoda Octavia (Mk2), 1.2 TSI (CBZB), DSG-7.
Friend from Beer Sheva. Hi did chain replacement just in case. No rattling, normal values.
1. Before chain change
At next oil change at 45K I going to check compression.
For this work I bought cylinder pressure meter at L.K. Ltd. for 150 NIS.
Compression universal check flow (important ones marked red): 1 - Engine warmed up to working temp, all thermal gaps are optimal 2 - Pull out all spark plugs 3 - Clean air filter and pull down gas pedal (for steel cable throtles)
4 - Disable fuel pump
5 - Disable ignition system 6 - Battery should be fully operationional and fully charged 7 - Starter should be fully functional 8 - Add charger to the battery
9 - Before shutting down engine for tests, press gas pedal few times to clean cylinders and valves
10 - Compression check occurs until there is no increase on tester
The procedure is easy, just read and follow instructions. Make sure to cover sensitive parts and do not use hard stream of water, sprayer is best for that.
Here are before and after pictures.
And a small video
Perfectly started after washing, no problems so far. Looks like a new ;-)
I will repeat it every year.

The engine number (“engine identification character” and “serial number”) is located on the engine directly above the joint separating the engine/gearbox.
In addition, the “engine identification character” and the “serial number” are indicated on the vehicle data sticker -arrow- which is located on the air guide pipe.
- As of letter “C”, four-digit engine identification characters are used.
- The first 3 digits of the engine identification characters refer to the displacement and the mechanical construction of the engine. They are type-punched together with the serial number on the cylinder block.
- The fourth digit indicates the output and the torque of the engine and depends upon the engine control unit.
It's interesting, same SSPs about same 1.2 TSI engine but every make (Audi, Skoda and VW) has some more details. Example: at Audi you can see construction of charge pressure actuator and different states with thermostats, etc. When looking on all of them you build big picture. I think Audi has the best SSP than others.
