Congrats on your purchase.
I should have seen this thread earlier though.
I owned a black 2001 a4 manual. Loved the car.
What is the mileage on the one you have...dont think I saw it posted it-.
Anyway my two cents on this is, yes the turbo..sludge.
..checking for that was crucial, but the B5 chassis, both passat and a4s had TONS of problems with front control arms, both upper and lower, along with tie rod ends and bushings going bad.
I would have suggested checking those prior to purchase, bc 80 percent of vehicles that were not properly maintained started having problems.
I think that the passat even had a recall on 98 through 00 models for the control arm issues....I would check bc that may have covered the a4s as well....
Good luck with everything...
All in all you just have to take good care of that car...My experience was that i will never buy another audi unless it has warranty...
