Setting Camshafts in 2003 Audi A4 2.0 ALT: Looking for Diagram and Guidance

Question

Hello.
Does anyone have an exact diagram of setting the camshafts in the Audi A4 2.0 ALT 2003? I got a car with the head unscrewed and I don't know how to set the rollers exactly? Thanks for any hints.

Cregen · Answer

If you did not have marked marks on the timing gears, it will be difficult for you to set it yourself, a friend once set the timing wrong in BMW and everything went wrong

if it's the 2.0 20v alt 96kw
you have a mark on the camshaft wheel at 12 o'clock and in the box window I send ins. installation or purchase of a lock for 100% certainty

Check the timing marks Attach the tension pulley Attach the timing belt in the order shown in the picture a -> b -> c -> d Rotate the tension pulley counter-clockwise Attach the securing tool T10008 Turn the tension pulley clockwise Remove the securing pin T10008 Hold the tension pulley in in this position 8mmTighten the tensioner pulley fixing bolt 30NmTurn the engine 2 turns by hand Check the tensioner Measure the distance:6 - 10mmIf this is not the case, start the assembly operation again Reassemble in the reverse order of disassembly

16 chain pins between the marks on the roller sprockets.

What did you set to the mark on the shaft or gear

2.0 alt
I folded the fights as in the picture, plus a belt for marks on the shaft. Unfortunately, this setting does not allow me to start the car. No compression on the cylinders. Do you have an idea what I'm doing wrong?

T5 · Answer

You have the rollers set wrong. There are supposed to be 16 chain bolts, you have 13.

It will be fine if the valves haven't bent yet, but I'm afraid it won't save money

matys1990 · Answer

I hope not, I always shake my hand to see if there's a collision.
I marked two places in the picture, should I set the separation on the red or green marks? because unfortunately there is a lot on these wheels

markings.

T5 · Answer

Greens.

trrol · Answer

buddy you have a bad sign on the suction shaft. You set it to the wedge, not to the arrow on the variator sprocket. The cams on cylinder 4 are probably at the top of the engine. The arrow is on the other side 180 degrees you need to turn the suction roller.

matys1990 · Answer

Thanks for the answers,
The only correct setting is to set the rollers on the roller wedges. Setting the variator to the arrow results in a lack of pressure on one of the cylinders.
The car works properly on the indicated settings.

@majsterek12345 unfortunately you were right, I damaged 2 exhaust valves, the cost is not high but troublesome.

trrol · Answer

Yesterday I did and not to cut under the variator wedge, only to the arrow on the variator.

In order for the first cams to be in this position, we need an arrow or a triangle on the variator, as in the diagram 2.0 triangle

And if you have two bent exhaust valves, you set the belt wrong, not the chain.

Anonymous · Answer

How many valves will bend if the timing belt is shifted, if the shifted shaft bends only 2 valves on one piston

trrol · Answer

Buddy, the thing about the engine is that if you set the belt wrong, the exhaust valves will break, the chain has nothing to do with it, because the exhaust shaft drives the belt, directly from the shaft, as the suction blows, it may be the fault of the belt or chain. The suction roller is to be to the arrow for a million percent, not to the wedge. There is no such a bad timing setting that there is only pressure on one cylinder. These things are only after a collision.

I used to put chocks in my Audi and the engine still runs today.

trrol · Answer

Yes, but probably 1.8 and not 2.0 ALT

Anonymous · Answer

If the belt drives the exhaust shaft, moving the belt can damage the exhaust and intake valves, if you set the belt right and move the chain, you will only bend the intake valves, if you set the belt and chain wrong, you can bend all the valves depending on which way you go wrong

zasilaczwarsztatowy · Answer

W 2.0 alt a4 b6

Anonymous · Answer

It doesn't matter if it's 1.8 or 2.0 or petrol or diesel, if you set it wrong it will bend, and it doesn't matter if it's 16 valves or 20 valves, whether the belt drives the intake or exhaust shaft or both, if you set the rollers wrong it will bend the valves and you can't help it. If someone doesn't understand this, don't take care of replacing the timing belt or repairing the head. So much for the topic

trrol · Answer

We are talking here specifically about the ALT engine. A friend claims that there is no mark on the variator, only a wedge and the car starts, it is physically impossible. The second claims that as per the mark set, there is no pressure on one cylinder, also physically impossible. He's messing with the chain and he's bent the exhaust valves, which the chain has no effect on.

Anonymous · Answer

I don't understand, you can explain it, does it affect or not the chain on the bending of the exhaust valves if it is moved

zasilaczwarsztatowy · Answer

Another important issue is whether the variator was blocked on the internal lock before setting the shaft and whether the variator was not replaced with another because not all of them fit. I was processing this topic in my audi with 2.0 alt, which takes oil, but I don't care.

ociz · Answer

There is no, because the exhaust shaft is driven by a belt, and the intake shaft by a chain.

Anonymous · Answer

So this means that if I move the chain by 4 teeth, the exhaust valves will not bend, because in fact it is as I said earlier, post 20

trrol · Answer

In this engine, you can move the chain as much as you want, you won't bend the exhaust valves so that there is a collision between the exhaust valves and the piston, the belt must be moved. because the exhaust shaft is driven directly from the shaft by a belt.

TRROL and you read post 20, what I wrote there, compare it with yours then read post 22 again if you agree with that
