I would like to know why there is a power difference of 23kW between A4 2.0T FSI Ambition 132kW multitronic and A4 2.0T FSI® quattro® Ambiente 155 kW S tronic even though they have the same engine. I am assuming ECU chip and gear ratio's :)

And is there a way to increase the power of the A4 2.0T FSI Ambition 132kW multitronic without voiding warranty?

Thanks
 
I don't have much knowledge about Audi's engine technology but it's probably the same as Mercedes.

The Mercedes C180 Kompressor, C200 Kompressor and C230 Kompressor all use the same 1.8L engine.
Some minor tweaks are made to the ECU mapping, boost and exhaust and they slap on another R20K to R40K onto the price tag.
It's all about the money ...

Oh and gear ratios will not affect the power output.
The manufacturer's use power and torque figures at the flywheel.
 
apparently the codes are

CAEA/CDNB for the 132kw
CAEA/CAEB/CDNC for the 155kw.

Considering they share an engine code CAEA , i'd bet good money the only differences are the external components to the engies
 
erm... well seems one may have valve lift and one may not!!
 
Must be a smaller turbo and intercoolers.
Its a detuned engine so I suspect its more than just mapping, there's cheaper hardware invovled.

You mean variable valve lift. Usually car manufacturers use detuned software and slightly cheaper hardware (smaller intercooler or turbo), but I think in this case it comes down to Audi Valvelift System.
 
AFAIK all the Germans do this.

Merc - 180, 200, 230, same engine
BMW - 323 & 325 - same engine
Audi & VW, all 1.8L models - same engine

Different mappings & (maybe) exhausts offer different torque levels for different driving styles

young VS old ?

Also different head gaskets & pully sizes. Yes in the end it's about market segmentation and making money.
 
As far as I know they use different torque heads for the turbo's and a slightly different ecu setup.
 
I highly doubt the ecu mapping has anything to do with it, its a different map for the changes in hardware.
They reduce costs of the engine parts, eg in the VW golf 4 110kW and 132kW, the 132kW had a lot of changes, turbo, ports, intake, intercooler, valves and gearbox. Many people thinks its just a map that was changed.

Even the Golf 6 gti and S3, they have the same size intercooler but the golf has plastic inside, the S3 has metal tubing.

you mean plastic end tanks for the g6
the g4 132 also had bigger brakes, k03s turbo, drive by wire
 
Ok...

The two gearboxes are very different.

Multitronic=CVT which is a bit unusual and will need getting used to. It's power delivery in it's various modes provides an uninterrupted acceleration experience in "D" (no perceived gear changes) , or simulated gear changes in "S" mode and Manual pedal changes. It is not created as a sporty box and not really a gearbox as it doesn't have gears in the strict sense of the word. This is the version I have with the 132kw engine. Torquey engine which doesn't really give the sense it's only 132 kw. Had a chat with my service advisor about mods and he made a good point that with my current tyres (18/225/40) I get wheelspin in 1st and 2nd, so mods might just mean more wheelspin (this was also his way of advising against it)

There are ways to increase the power with FRC seemingly most preferred. Software only will generally give around 200.x bhp which is roughly the true dyno result of the 155kw. There are however concerns around warranties and motorplan, however these generally target when things go wrong more so than being the immediate write off. Modifications are however done at your own risk, be warned, however going with FRC does mean the comfort of knowing that many other users have been using the software in local climates.

The 155kw has slightly more torque (and power obviously) comes with the s-tronic (DSG/PDK) double clutch box that is quite sporty, also provides normal auto mode in "D" which however has percievable gear changes (normal auto) and a rather sporty "S" mode.

This vehicle combined with Quattro is pretty quick to a 100, and does indeed feel more sporty. The valve lift is meant to promote good fuel economy however that is not to say the standard (132kw) one is bad.


Considering the new 125kw 1.8T one must question whether the 2.0T will continue being offered.

All in all I say test drive both at normal speeds in their various modes and at "full Brakpan" driving and determine the verdict.

Good shopping!
