Hi everyone, I just wanted to know which of these engines would you choose and why???
1.8T, 2.0T, 2.7T or 3.2L????
From what i heard,,the 1.8's always seemed to have some issues (mech. and electical)
the 2.0T seems to be a good engine...
the 2.7 I hear had some issues, especially with the turbo's
and the 3,2L where just BAD...
am i right with any/all of these?
This would be for either an A4 or A6 car..
love to hear your input..
thanks

2.7t in a6. Because it is very tunable and very stout and powerful from the factory. The turbos are an issue but if cared fOr properly they will boost happily for the cars life.

The biggest problem is some people don't wait until the oil temp is high enough for WOT. Some other problem is over boosting.

 

Hi Bud, thanks for writting. Glad to see you like the 2.7T...i know what you mean about turbo operation...i'm the same way, when i start my volvo, i wait till the revs come down to where they should and start to drive easily until the temp is where it should be. If i have to stomp on it, i'll wait until i've been drving for a bit. Once i've arrived to my final stop, i put it in park and let it idle for maybe 30sec...this a good habit?
I also do my oil changes every 5-6000km...RELIGIOUSLY!!! it always bugs me when i hear people say "oh, the dealer said" or "the manual says to change oil every 12-15000 km..i find this to be wayyy to long. Oils are oils..they all break down. I think this is a major problem for most cars today cause they will break down quicker and/or develop sludge..

Yes the cool down is a very good way to ensure proper turbo cool down. Another way would be to just take it easy when destination is close. Start drivin gently when you are 1-2 miles away from your destination and let it idle for 10secs and turn off.

I also change the oil on my 2.7 every 4-4500 miles.
I change early because most of my miles are city driving and engine oil gets to operating temp very rarely.

There have been some UOA done on some 2.7 with 7k on it and the report came back rather well, but it's mostly highway.

 

Hi there..so besides the HP difference and engine size, are there any differences between the two? are they both good and reliable?
I've seen some A4's, one with one engine and one with the other.
My reasoning is that i think i would prefer a N/A engine vs a turbo. I'm a little iffy on the turbo's in these cars and prefer a non turbo. I know that the 3.2L (in a 2006 A4) is a chain driven...right? Is the 3.0 the same (in a 2005 A4 wagon)?
thanks

I can speak for the 3.0:
Common failures (major): catalyst converters. The 3.0s have converters failing at a very high rate and changing it is very very hard.

Cam lobes failure. Results in engine replacement or cam replacements. Both are very exPensive.

Honestly I have read that the 3.0 is harder to work on than the 2.7 or 4.2. The timing belt is also harder on the 3.0.

If you want reliable you CANNOT go wrong with the 2.8. That engine is the corolla of Audi.

Dont know much about the b7 or b8 platform, but if the 2,0 is FSI It is my understanding that the 2.0 with fsi have the same cam lobe issues as the jettas with 2.0t fsi have.

Also all fsi engines are prone to carbon buildup thanks to direct injection.

 

id choose the 1.8t. i own one, so i know a lot about them. there a bit older, so more general knowledge about them and aftermarket support. most importanly, no fsi bullshit to deal with. they are much easier to work on than the 2.7 because of space. if you take the time to learn about the 1.8, and maintain it well, it will be a great engine for many miles

 

I chose and would certainly choose again, the 3.2. Great match to the A4 cabrio in terms of power, smoothness and balance for the vehicle overall--not sure where the "just bad" part of that comes from... Had a 2.0T version as a dealer loaner during maintenance and we really did not like the 2.0T at all.

Had a 1.8 225hp in a TT at one point, no issues, but it was not as smooth as the 3.2

Had a 2.8 in a previous GTI, smooth, no engine issues, but it seemed to nose heavy in the car

Drive em all. Better yet, see if there's a way to rent or borrow each for a week or so. See for yourself.
