Does the 997.2 Turbo have the coolant pipe and cam issues the 997.1 Turbo had. How reliable is the 997.2 Turbo compared to the 997.1 Turbo. Have there been any problems with the PDK Transmission. Thinking about a change. Thanks!

 

Different engine, no cam or coolant pipe issues. PDK is one of, if not, the best auto transmission. I am a MT guy, but have a PDK type trans in my '08 Audi S6 and they are impressive. There are .2's with MT's but I am not sure what the price effect would be.

There are Mezger lovers and DFI lovers. The .2 is newer technology delivering 10 more horsepower stock and better fuel economy, however the upside of the Mezger is that you can push 800HP (with a lot of mods), while the DFI might get you 650 or so with mods. Both really need an exhaust, but another area where the .2 excels is in technology. You have updated electronics that can make a big difference. In reality, most people don't go past 600 - 650 anyway so the upgrade issue is really moot. The other changes were some significant work done on the suspension.

Not much of a downside to a .2, similar power, better tech, no reported issues (spun cams/popped coolant pipes). At some point you will need to deal with normal maintenance, like 10 year old coolant hoses, but that goes for any car. The only thing about DFI is the potential for carbon build up, but I have never read about anyone having this issue. My '08 S6 is a DFI engine and I need to do this (started feeling the effects at about 150,000 miles - some get it at 70,000, but I drive the car like it's meant to be driven) now at 196,000. I don't think there are many, if any, DFI 997 engines with that many miles, and they may have figured out something to alleviate the carbon issue and that is why there are no reports of this in the .2 DFI's.

I did see this post in a thread a couple of years ago:

"I believe the carbon buildup is the result of DFI combined with oil consumption. The Audi/VW problem was really the result of the crankcase pressure not being well controlled. This caused excessive oil to be consumed via the crankcase ventilation pipe to the intake. That combined with DFI resulted in excessive and early carbon buildup in the intake manifold and on the intake valves, limiting airflow. They seem to have really improved the situation. I have a 2016 Audi A6 2.0 and a 2016 VW Golf with 1.8. Both have no/minimal oil consumption. I believe it will take some time before either needs to have the intake areas cleaned. I have read about people installing catch cans in these newer cars and end up not catching any oil at all. It is my guess that carbon buildup with Porsche DFI engines might depend on how much oil the engine consumes. By the way, Toyota had a famously similar problem for many years with port injected engines.

The solution appears to be the use of port injectors with DFI by manufacturers which seems to be more and more common."

In another thread there was this picture:



Which is NOTHING compared to this Audi DFI engine:



So, like I said, the only known downside to DFI is that the valves are no longer being "washed" by the fuel since it is being injected directly into the cylinder, though the Porsche injection comes in on an angle that seems to hit the back of the valve, so that, and the PCV system employed, may be why there are no reports of this, unlike in the BMW & Audi forums.



Back to your original question, while there isn't as much race experience as the .1 engines, there are almost no reliability issues reported with the .2's with better fuel economy and you get this along with the updated technology and a redesigned suspension. Just make sure you get an exhaust!

The 9A1 engine in the .2's is simply an amazingly reliable and modable engine!! The PDK is very very reliable too.

I've done 8000 miles in less than two years with my 997.2 TTS with lots of spirited mountain drives and a couple of trips to the drag strip and I've had ZERO issues!!!

I did the major service (6 year and PDK service) last year and It's not the cheapest, but once done, I'm good for thousands more reliable miles.

Just an exhaust and mild OTS tune and my car runs mid - high 10's and totally bullet proof. Not much out there better in my opinion!!

 

Thanks for the responses guys. Very much appreciated!

 

I too had this same question about 3 years back. Should I go .1 or .2, I went .2 and never looked back. My car is a complete stock engine and World record holder with Bolt-ons. car is making 900 WHP and I daily drive it to work never seen anything so reliable. Drives like stock. See thread with pictures and mods. Hope this helps.

I SO want to mod mine up like yours someday!!!

 

i would go with the .2

if you dont want a 6 speed gearbox . the tiptronic was nothing for my in a sports car sorry ..

PDK is an another world !
