This is my first post on this forum, so first introduce myself.
My name is Borja (Bor) and I'm from Spain.
I would like to apologize for my English, but does not dominate a lot and use a translator to participate in the forum.
I own a Audi A4 b5 2.5 TDI V6 AFB/DQS year 99. (FWD, non quattro...)
It has many modifications, later publish a photo.

It 245000Km, and I have worn camshaft.
The car has an ECU reprogramming, and doing quite well, but I noticed that he has lost strength and tear costs.

I wonder if it's worth a repair kit camshaft like this (Nockenwellen Kit VW Passat Variant (3B6) 2.5TDI AFB AKN AYM BFC FEBI NEU | eBay) or, conversely, look for a current engine (the 2.5 TDI BAU for example) for scrapping in good condition
Does anyone have some information about whether this modification would be possible?

What do you recommend?

A greeting and thanks for responding.
