I hooked my Mk4 up to vag com and cant figure out the issue I have had it ever sense I have had the car and cant get it to go away. I have changed the D.V. and upgraded it sense I have had it and it still comes back saying check it. I haven't been able to find much on the code.
17705 - Pressure Drop between Turbo and Throttle Valve (check D.V.!)
P1297 - 35-10 - - - Intermittent

Second is this:
18010 - Power Supply Terminal 30: Voltage too Low
P1602 - 35-10 - - - Intermittent
That one just started showing up, I have checked the battery cables and the connection on the alternator but I assume that the alternator is going bad...

And finally:
01358 - Internal Central Locking Switch: Driver Side (E150)
27-10 - Implausible Signal – Intermittent
I just changed the passenger side door actuator and got my alarm to beep when I lock it but now It isn't and the only code is that one. It still functions fine and will set the alarm off when I open the door.

These are the codes that have be flustered right now.. usually don't have this issue but these 3 have me.

You have a boost leak or vac. Leak.
Not sure on the others.

Anything you would check first?

definitely boost leak. very easy to check. then type in the other codes on rosstech wiki (google search rosstech wiki) and it will tell you symptoms, causes, and how to fix it.
