Well, I'm not sure how helpful this will be to you, but it is straight out of my service manual. Apologies in advance for the wall of text, like I said, straight copy and paste.

Camshafts and camshaft adjusters, removing and installing
• Removing
• Cylinder head installed
• Remove noise insulation panel -arrows-.
• Remove front bumper
• => Repair Manual, Body Exterior, Repair Group 63
• Move lock carrier to service position
• => Repair Manual, Body Exterior, Repair Group 50
• Remove ribbed belt => Page AUDI-B5-GE05-13-001-0113-1.
• Remove toothed belt => Page AUDI-B5-GE05-13-001-0213-4.
• Left cylinder head
• Remove left-hand cylinder head cover => Page AUDI-B5-GE05-15-001-0315-22.
• Right cylinder head
• Remove right-hand cylinder head cover => Page AUDI-B5-GE05-15-001-0315-25
• All:
• Unbolt Hall sensor housing (10 Nm).
• Remove bolt securing Hall sensor rotor (20 Nm) and carefully lever off rotor using a screwdriver.
• Insert camshaft clamp 3391 in securing plates of two camshafts.
• Loosen both camshaft bolts and remove approx. 5 turns.
• Take out camshaft clamp 3391.
• Pull off both camshaft sprockets with special tool T40001.
• Using a screwdriver, carefully pry oil feed lines for camshaft bearings out of camshaft bearings.
• Make sure that the retaining catches do not break off when prying out the oil lines.
• Secure camshaft adjuster using retainer for chain tensioner 3366.
• Note:
• Do not over tighten retainer for chain tensioner, otherwise camshaft adjuster can be damaged.
• Check TDC position of camshafts once again.
• Note:
• The two markings on the camshafts must be in line with the two arrows on the bearing caps.
• Clean drive chain and camshaft chain sprockets in vicinity of arrows on bearing caps and mark position of chain on sprockets with paint opposite two arrows.
• Note:
• The distance between the two arrows (and thus between the paint markings) is 16 rollers on the chain.
• The notch on the exhaust camshaft is offset slightly towards the inside in relation to chain roller -1-.
• Do not mark the chain with a center punch or by making a notch or similar.
• Remove bolts securing camshaft adjuster -6-.
• Remove bearing caps 1, 3, 5 and 7 from inlet and exhaust camshafts and place them in correct order on a clean surface.
• Loosen bearing caps 2 and 4 alternately and in diagonal sequence, and remove from both camshafts.
• Take out both camshafts together with camshaft adjuster.
• Installing
• Replace rubber/metal gasket for camshaft adjuster and apply a thin coat of sealant D 454 300 A2 to the shaded area.
• Install drive chain on camshaft sprockets as follows:
• When the old chain is being used again, install the chain so that the paint markings (arrow) are in line.
• When a new chain is being installed, the distance between the notches -A- and -B- on the camshafts must be 16 rollers on the chain. The illustration shows the exact positions of the 1st and 16th rollers on the sprockets.
• Notch -A- is offset slightly toward the inside in relation to chain roller -1-.
• Insert camshaft adjuster inside chain (second mechanic required).
• Locate camshafts with chain and camshaft adjuster in cylinder head.
• Oil camshaft bearing surfaces.
• Note:
• The dowel sleeves for the bearing caps and camshaft adjuster must be in the cylinder head.
• Install the bearing caps so that the markings on the bearing caps can be read from the inlet side of the cylinder head.
• Tighten bolts securing chain tensioner (watch position of dowel sleeves).
• Tighten bearing caps 2 and 4 of inlet and exhaust camshafts alternately and in diagonal sequence (watch position of dowel sleeves).
• Install two bearing caps next to chain sprockets on inlet and exhaust camshafts.
• Check correct setting of camshafts:
• The two markings on the camshafts must be in line with the two arrows on the bearing caps -arrows-.
• The distance between the two arrows on the bearing caps (or between the paint markings) is 16 rollers on the chain.
• The notch on the exhaust camshaft is offset slightly towards the inside in relation to chain roller -1-.
• Prepare shaded areas on double bearing cap -1- and bearing cap -7-.
• .... by applying a thin coat of sealant D 454 300 A2 and install bearing caps (watch position of dowel sleeves).
• Install remaining bearing caps (watch position of dowel sleeves).
• Install new oil feed lines for camshaft bearings.
• Install new oil seals for inlet and exhaust camshafts; installing => Page AUDI-B5-GE05-15-001-0215-10.
• Remove retainer for chain tensioner 3366.
• Note:
• When new lifters have been installed the engine must not be started for about 30 minutes. The hydraulic compensation elements must settle (otherwise valves will strike pistons). Then turn crankshaft two full revolutions before starting.
• After working on the valve gear, turn over the engine carefully at least two revolutions by hand to ensure that none of the valves make contact when the starter is operated.
• Seal end points of joints between bearing caps and cylinder head.
• Before installing cylinder head cover and gasket, carefully apply a small quantity of sealant D 454 300 A2 at four end points of sealing surfaces on cylinder head -arrows-, using a small screwdriver.
• Install cylinder head covers => Page AUDI-B5-GE05-15-001-0315-22.
• Install toothed belt => Page AUDI-B5-GE05-13-001-0213-4.
• Install ribbed belt => Page AUDI-B5-GE05-13-001-0113-1.
• Tightening torques
