Hello diesel mechanics,
Can anyone tell me if an intercooler from an RS4 will also fit into an A4 TDI (year 1996, engine code AFN)?
It would be very important because the old LLK is broken!

Best regards,
K.R.

Hi,

Are you planning to make any further modifications to the engine?

If not, another LLK (likely referring to a specific type of product or treatment) probably won't make much difference.
There have been discussions about this before, when my troubled mind wasn't fooled by some lazy magic trick...

Ein großer LLK kann seine Kapazität erst bei mehr Ladedruck auspielen; mehr Ladedruck braucht auch mehr Einspritzmenge. USure, here's the translation:

'sw.' translates to 'southwest' in English.
Ultimately, more NM also requires more clutches icon_wink.gif.

The engine has been chipped, increasing the power by approximately 40 horsepower. However, the fuel injection amount is a bit too high, which causes it to smoke when running at full throttle.
Therefore, the VNT-15 loader will soon be replaced by the VNT-17.
Since the water pump is already broken, I thought I might as well install a larger one while I'm at it.

Hi,

Perhaps you should try a different linkage from a 2.5 V6 TDI – it was available on the standard A4 body style and should fit.
And it's likely to be even bigger than your current one.

However, there may be problems connecting the pressure pipes if they have a different format.
I can't say that with certainty.
