Hey people, need some more help.

Having a little trouble with idle control. I've just plugged the VAG-COM in and there are 3 regularly occuring problems in the engine, but I dunno where to look to get some more technical data to solve them.

The faults are:

18010 - Power Supply Terminal 30: Voltage too Low
P1602 - 35-00 - -
17972 - Throttle Actuator (J338): Under-Voltage during Basic Setting
P1564 - 35-10 - - - Intermittent
17973 - Throttle Actuator (J338): Lower Stop not Reached
P1565 - 35-10 - - - Intermittent

There are no other faults found but these are very obvious when driving, the car occasionally shudders and almost stalls every now and again. I was hoping to find a problem with the MAF or some other sensor but nothing seemed to come up.

In dire need of assistance

Cheers
