"S" or not "S" One for the pundits.


Recommended Posts

I have a 2003 Carrera 2 Tiptronic. I am not sure if it is and "S" . There is no "S" on the rear, it just says Carrera.

Now in the generic Carrera handbook there are two descriptions for the 2 wheel drive Carrera. It is either a Carrera or a Carrera Tiptronic S.

In terms of engine output there are two ratings in the handbook for the Carrera:

Engine type M96/03 (320Hp)

Engine type M96/03S (345Hp) High power version

The engine number of the vehicle is: M96/03AT 66566759 (I assume the AT refers to the transmission type?)

The vehicle's VIN is : WPOZZZ99Z 3S607135 (Is the "S" the giveaway here?)

Is it the case that all Tipronic models are called: Carrera Tiptronic "S" as they are fitted with the higher power engine?

and that all manual models are either:

Carrera or Carrera S depending on whether they are fitted with either the 320Hp engine or the 345Hp engine?

Thanks for the swift reply. I have looked at the VIN decoder, but confirmation is useful.

What about the "AT" in the engine number. I see from a similar current thread that this could refer to: "AT is short for Austausch". Does this mean that my engine has had a factory rebuild at some time?

Regards

The 665 prefix in your engine number is signifies a MY2005 engine (- your original engine would have has a 663 prefix).

Since your car is a MY2003 it would appear that the engine was replaced in 2005 (or early 2006) with a factory new or rebuilt.

I think that is likely a good thing.

Well, I contacted Posrche UK who tell me that the original engine in my car had the number M96/03 663***** which as you say, from the 663 prefix, is consistent with an engine fitted in 2003. Therefore, my 2003 car had a different engine fitted sometime in late 2005/early 2006 with the Number M96/03 AT 665*****.

Porsche would not confirm this fact in writing without receiving a fee of £65 claiming that it would be a legal document.

What I found really interesting is Porsche UK had no idea what the "AT" stands for, allegedly claiming its presence as a complete mystery. Now we know that "AT stands for:Austausche, which means exchange in German. I have asked Porsche UK to seek information from a higher authority in Germany. However, I am unlikely to receive a letter unless I pay for it.

I am pleased that I have discovered the engine change and I am hopeful of receiving confirmation of the fact from Porsche. It's still a great car, made even better with a newer engine.
