What one do you have? POP YOUR HOOD AND READ THE BADGE

1. FSI (found in 2006 and up to 2008 models) DSG and 6spd Manual
2. TSI (found in late 2008.5 and up models) DSG and 6spd Manual

The U.S. Spec TSI is NOT the 1.4L Turbo and Supercharged engine that is found in the UK; rather it is second generation, if you will, of the FSI. A 2L 16V direct injection engine - with an IHI Turbo.

Official TSI SPEC SHEET from VW (courtesy of Arin Ahnell @ APR Tuning)

Engine Code: CCTA OR CBFA
Type of Engine: Inline 4-Cylinder TSI Engine
Displacement: 121 cu in (1984 cm3)
Maximum Power: 200 hp (147 kW) at 5100 - 6000 rpm
Maximum Torque: 206 lb ft (280 Nm) at 1700 - 5000 rpm
Number of Valves Per Cylinder: 4
Bore: 3.2 in (82.5 mm)
Stroke: 3.7 in (92.8 mm)
Compression Ratio: 9.6 : 1
Firing Order: 1-3-4-2
Engine Weight: 317 lb (144 kg)
Engine Management: Bosch MED 17.5
Fuel Grade: 95/91 RON
Exhaust Emission Standard: ULEV (CCTA) - SULEV (CBFA)

Some major differences from the FSI to TSI include:

- chain driven belt
- fuel/engine management
- components in the intake system
- oil filter and oil dipstick relocated
- improved PCV system (proved to be problematic in the FSI)
- compression ratio lowered to 9.6:1
- more balanced cam shafts in the center of the block on both sides
- down pipe
- fuel efficiency (debatable)
- better emissions
- more 02 sensors on exhaust system

....The fuel system is now run off of a new lobe of its own to reduce wear, which was a problem with some of the earlier 2.0t engines(from the tech's mouth). It is now also run off of the exhaust cam and no longer the intake cam. The tech noted that the injectors must overcome the combustion pressure of the engine to even force fuel directly, causing them to have operation pressures upwards of 1400 psi. Fuel mileage tech: The intake runners have a plate splitting them into two pathways. In the intake manifold exists individual butterfly valve like air flow splitters that direct the airflow into only half of the intake runners while cruising or coasting, thus increasing gas mileage. The airflow is directed into both paths when the engine is under load to increase air flow and power. Other notes: The intake is not part of the engine cover, and the sound pipe can easily be removed.....

PZEV and SULEV are basically the same emissions rating, but PZEVs have a 15year/150000mi warranty and zero evaporative emissions. http://localdc.com/pzev.htm

Every day, there are more and more mods being introduced for the TSI. Revo, APR, GIAC, and Unitronic all have software/flash capability (may vary depending on your ECU box code; as many as ~15 different ones)

Intakes have been released by companies (11/08). NA Motorsports has released one by VF Engineering. BSH has their own system (available as stage 1 and stage 2). Neuspeed has a p-flo, APR has released Stage 1 (by Carbonio) and stage 2 is in the works, AWE also has their own custom setup in the making....

Downpipes from FSI applications can be modified to fit TSI cars depending on what engine code you are (CBFA vs CCTA). The mating flanges are slightly different (will require modification) and there is an extra 02 sensor in the stock CBFA setup. (consult your preferred dealer as to what software would clear a downpipe CEL).

TSI specific Downpipes are available from various companies; including ones for CBFA. Do a search - i hear it's amazing.

Catbacks remain the same from FSI to TSI.

There are boost tap kits to make stuff work for our cars that worked on FSI (boost gauges, Forge DV's). Some of the more popular ones are made by BSH, AWE, and 42DD

Suspension remains the same. Maybe a few aesthetic parts here and there like an extra rubber mount or bushing.

GTI's appear to have alower suspension than stock 2006-2007, but only by a little.

Front and Rear sway bars are the same.

Popular abbreviations and acronyms associated with VW/AUDI:

TSI (Turbo-Stratified Injection)
FSI (Fuel-Stratified-Injection)
CCTA
PZEV
CBFA
SULEV

i will update this as more information becomes available....everyone feel free to post more info to be included...i will add it to the original post and give you credit if you wish, just delete your post after i acknowledge it so this thread doesn't become 234324 pages long.

EASY WAY TO TELL IF YOUR CAR IS CCTA OR CBFA
Pop open your hood and inspect your factory airbox. If the airbox has a 2nd hose coming out of the front of the airbox then your car has the CBFA version of the airbox.
The CBFA version also has a 3rd sensor (a 2nd o2 sensor) on the DP that is used for emissions purposes.

Oil Change in a TSI Motor:

Quote, originally posted by VeeRrrSick »

The good news is that you don't need to touch these covers on a TSI for an oil change. I did my first one at the first 1,000 mile mark just to train myself (and to see if there was any metallic content). The drain plug is accessible (points toward the rear), and the process is very painless. 1. Put the warm car up on ramps or jack stands 2. Remove the drain plug (19mm socket) 3. Remove the oil cap to speed draining 4. Once the flow slows significantly, loosen your oil filter slowly until you hear the flow increase again. Let it sit partly unscrewed and drain. (There's a breech pin that'll open if you haven't read about that--it's great.) 5. When the flow slows down significantly, unscrew the filter the remainder of the way by hand and pick the filter straight up. There shouldn't be any mess. 6. Lube and install the new filter. 7. Replace drain plug (no new crush washer is necessary from what I've read... the washer's permanent on the drain plug). 8. Fill 'er up. 5 qts. Start with 4.5, run it to get oil into the filter, and check. Add as needed. Enjoy the relatively painless process! I had a blast... and plan to do changes between dealer maintenance just for the peace of mind... and the relaxation. Modified by VeeRrrSick at 6:18 AM 5-21-2009

Read this for TSI INFO/FAQ (MODS: sticky this thread plz!)

I know for a fact that I have the TSI.....but what's the difference between the CCTA & the CBFA versions!?!?

I'm in Michigan...so I don't have a emissions strict one

So then you either have the CCTA or the CFBA engine code....we just need to figure out which ones go with what type of engine (non PZEV vs. PZEV), lol

We'll just never know....there's like NO info on this car (specifically the motor) at all

Last time I checked the VW site they still had the '08 GTI on there & were still showing the FSI motor in it, LOL

But yeah....certain states have to have the PZEV cars (like California & some of the northeast states).....so that's why I was wondering if the CCTA/CFBA meant the difference between PZEV & non-PZEV

I'm almost 99.9% positive when I was at the dealer on Tuesday & he pulled my VIN it said CCTA for the motor code (doesn't say anything on the sticker sheet)

So I think the CBFA is the PZEV version & CCTA is the non-PZEV version

2009 GTI - APR 93 STAGE I - INTAKE -14.0 @ 101MPH

2006 PASSAT-AUTO - 14.3 @96MPH-260HP
APR 93 STAGE II - APR TBE - INTAKE - NS PULLEY - NS GAUGE
EJ PCV FIX - 18" ACE DIMENSION-TOYO PROXES4

Alrighty so as Im sure you guys are aware of (those guys that own 2009s that is) the 2009 models come with a "Carefree Maintenance" program. Today I had setup to meet for the Courtesy Vehicle Check, and for some reason I thought that they would change the oil. I guess when I called in and made an appointment I stated that I wanted an oil change or whatever. Anyways, once the "Courtesy Vehicle Check" was done I was handed an $80 bill for doing an oil change Do yourselves a favor and change your own oil before you do your Courtesy Vehicle Check and just have them inspect all the fluids. I wasn't expecting a bill. That's what I get for not looking up something in advance

ouch. glad i have an 08

Vortex tested, reverse shocker approved.

Quick story: This GTI was over-revved to 8900 rpms and some valves and lifters were destroyed. I am assuming the owner accidentally miss shifted.

The first thing that the tech, who was a VW enthusiast himself, told me was that the entire valve train and head can be removed assembled to access the engine internals. Thus the advantage of this is that if you were to replace piston rings or need to access the engine internals, you can do so with out disturbing the valve train. He noted that he removed the head cover and the cam shafts were just sitting there, as the bearings are built into the case.

The fuel system is now run off of a new lobe of its own to reduce wear, which was a problem with some of the earlier 2.0t engines(from the tech's mouth). It is now also run off of the exhaust cam and no longer the intake cam. The tech noted that the injectors must overcome the combustion pressure of the engine to even force fuel directly, causing them to have operation pressures upwards of 1400 psi.

Fuel mileage tech: The intake runners have a plate splitting them into two pathways. In the intake manifold exists individual butterfly valve like air flow splitters that direct the airflow into only half of the intake runners while cruising or coasting, thus increasing gas mileage. The airflow is directed into both paths when the engine is under load to increase air flow and power.

Other notes: The intake is not part of the engine cover, and the sound pipe can easily be removed.

If anyone has questions, just ask. I probably know the answer, I just can't think of anything else new about the engine at this moment to post.

Correct. However I was still kind of leary putting 10k on a brand new motor without an oil change..... I misunderstood what the free 6k maintenance inspection was comprised of and I ended up spendin some extra cash.

Thats what my dealer first told me when he was selling me the car. However he corrected himself and apologized since when I bought the car it had only been on the lot for 3 days and they were still learning about the 09s

VW, and subsequently all VW dealers, are on the hook for this. The PZEV GTI (Tier 2, Bin 2) is even cleaner than the Prius (Tier 2, Bin 3), which makes me wonder why my tailpipes still have soot?

Tier 2, Bin 10: Least clean…
Tier 2, Bin 9-6: Getting cleaner…
Tier 2, Bin 5: Average…
Tier 2, Bins 4-2: Getting even cleaner…
Tier 1, Bin 1: Cleanest, equivalent to CARB’s ZEV standard (see below)

http://www.autobytel.com/conte.../1478

... back to top!

1. When I push unlock on the driver door the thing clicks like 3-5 times sometimes.
2. My brakes squeak when the car is cold for the first minute. Not fully convinced it's the pads, though, and it's completely gone after that 1st min.

Not too bad. Is yours a PZEV?

I've noticed that during the winter if it is really cold or if there is any condensation the first few times I break there is some minute brake squeaking. After a few short stops the sound subsides. Should be normal.
If you get some upgraded brake pads however there could be some additional noise.

EDIT: x2 for sticky!!
We should get some of the more major TSI threads sticked to avoid the repetive answers.

I'm guessing a major difference is that PZEV engines have a different ECU, explaining why APR Stage 1 is compatible (yet).

Anyone care to elaborate further?

google/wiki PZEV. it's not exclusive to VW - it's pretty much a government standard depending where you live (and if your state government is choosing to abide by it)

APR software is compatible with both CBFA and CCTA - the incompatibility issues lie in your ECU box code (there's as many as ~8-10?) APR from what i've heard/seen have cracked almost all. i would call APR or talk to (mike/arin) on here and give them your car information.

they'll prob send you to an APR location if necessary so they can get a better understanding. it's a matter of a simple upload and download on a laptop connected to your car.

i doubt you would even need to do that, though.

Yeah I understand what PZEV is (simply a designation for "grading" a cars emissions into a certain class, PZEV, ULEV, LEV, etc)

We tried to do a trial flash today on my 09, no luck as APR doesn't support my ECU yet, but we did send in the code extract from the ECU to APR to take a look at.

Arin and Keith have been awesome btw, really awesome customer service they have over there.

Xing my fingers that they will be able to support my car sometime soon, the current promo that's going on is an awesome deal.

I actually went to see if I could get trial stage 1 software and they told me the code for my car wasn't cracked yet

At least they'll be able to crack another one when I bring the car in again.

sounds like what i had to do initially. and yes, they're awesome people and go the extra mile.
