Wow, I'm really new to the Audi world. Just got a 2005 A4 Cabrio 1.8T. So here's 3 newb questions:

1. I'm assuming my car is a B6 based on this forum, but it looks like there was a update in 2005.5. How can I tell which I have? Sounds horrible I know.

2. I would like to give it more power. Where do I start? I'm thinking K&N air filter first. Beyond that, what should I do? Looks like cold air intakes aren't effective on the 1.8T. Appreciate any direction.

3. While I'm at it, what other upgrades should I consider?

Thanks!

 

a chipped ecu would do a lot for your car.

theres a big body difference between b6 and b7 models. look at pictures of 2006 and 2004 models. if it looks like an 04 its a b6, an 06, a b7.

 

I've looked at several 2005's and several 2006's, and I can't see the difference. Guess I'm not familiar enough (only had my car 2 days). Is there something specific that changed from the b6 to the b7?

Regarding an ECU: do you have one you recommend, and are they hard to reprogram, or replace? Doing a quick web search, looks like the APR ECU would do the trick?

I appreciate the help!

 

Look at the differences between the front ends of the car.

B6:


B7:

 

I was looking on autotrader and if you look at cards for sale that are 2006 A4 Cabrio's, they look just like the 2005's. I guess the A4 sedans got the upgraded body in 2006, but the Cabrio's didn't?

 

oh yeah i didnt think about that.

 

Check out this page on Wikipedia. It should clear everything up.

 

Now it makes sense, especially by this point:

The B7 Cabriolet model arrived later than the other two body variants, with sales beginning in February 2006. Brand new on the Cabriolet was an entry-level 2.0 TDI version, but to date this is not being offered with the Multitronic gearbox.

Thanks for the help!

 

I believe both the B6 and B7 cabriolets have similar rear ends.

Like mentioned above, since you have the 1.8T, chip should probably be the first upgrade in order to get more horsepower.

 

Compared to the high price-power gain ratio of chipping, an intake has a pretty low ratio. Intakes aren't even necessary until your getting into serious power. Other than that, if you'd still like one the only one worth the money is the Carbonio. looks sick as fk, makes your engine sound better, plus gives you a little something IMO. With a forge 007 diverter valve and the carbonio installed on my car, it feels less 'peaky' now and more smooth and drive-able
