My polo 1.0 has just brought up this code,

Polo Idle Speed Control Valve

My dad says its pretty simple to fix, and its inside the throttle body.

Just asking is this a common fault ?

Kind Regards PJ x

Clean the throttle body thoroughly with carb cleaner, then perform a TBA on it using vagcom

I wouldnt say its a common fault. It can happen when the throttle body falls out alignment, or is cleaned and not reset.

Procedure for performing a Throttle Body Alignment on DBW Cars using KWP-1281:
(Check to see if the engine speaks KWP-1281 by looking in the top left of the Open Controller Screen Some examples of KWP-1281 engine controllers are 2000+ Golf/GTI/Jetta/New Beetle/Audit TT 1.8T)

Turn the key on but do not start the car.

[Select]
[01 - Engine]
[Measuring Blocks - 08]
Group 060
[Go!]
[Switch to basic settings]
Once you do this you will see the top right display say ADP RUN. The TB adaptation is being done as soon as you switch to basic settings. You will see the values change and hear the TB cycle for the first few seconds then it will stop. Leave it in Basic Settings for about 30 seconds.
[Switch to Meas. Blocks] button and you're all set.

Be sure not to touch the accelerator and make sure the engine is NOT running when you do this!

all fixed.

turns out it was a split air hose.

Let me guess....the one that goes from the throttle body to the brake servo? They split all the time
