i got a MIL a few days ago and VaGd the CAR got these codes, clear them and after 2 days they all came back.

16684 - Random/Multiple Cylinder Misfire Detected

P0300 - 008 - Implausible Signal - Intermittent

16398 - Bank 1: Camshaft B (Exhaust): Retard Setpoint not Reached (Over-Advanced)

P0014 - 001 - Upper Limit Exceeded

16686 - Cylinder 2: Misfire Detected

P0302 - 008 - Implausible Signal - Intermittent

17522 - Oxygen (Lambda) Sensor; B1 S2: Internal Resistance too High

P1114 - 008 - Implausible Signal - Intermittent

16805 - Warm Up Catalyst; Bank 1: Efficiency Below Threshold

P0421 - 001 - Upper Limit Exceeded - MIL ON

I don't know if there is a pattern here because they are all related to the same BANK 1 any ideas?

 

You have your codes & descriptions mixed up a little.
Besides that it looks like a bad o/2 sensor & a cam solinoid/oil pressure issue. You will have to look at data & see what is going on with the cam solinoid. I would also get a back pressure test. You could be getting misfires & cat efficiency fom a bad cat. Check the freeze frame data & see at what rpm the misfires occured.

 

I was going to say I hope all VAG COMs don't read that way...

That timing fault is concerning...

Rule of thumb with anything concerning timing is making sure timing belt timing is correct first.

If everything is ok, You have to inspect the adjuster. There are certain things to look for which is hard to describe. But you need the cam locks to even check timing. You got some stuff going that needs to be checked out professionally

 

is there a way using vagcom to check timing or in any case test the camshaft?

 

i cleared codes 2 days ago and i got a MIL yesterday night but this time i only got 1 code.

16398 - Bank 1: Camshaft B (Exhaust): Retard Setpoint not Reached (Over-Advanced)

P0014 - 001 - Upper Limit Exceeded

you think that probably my cam sensor might be the problem?

 

so it seems that im only now getting the 16398 code but it comes on like every 2 or 3 days, is there a way i can check timing using vagcom? i did the group 96 test and it said system NOT ok but ill change the cam sensor to see if it clears
