2011 Polo TSI 1.2 CBZ engine - Misfire

[mickey81]

Hi

Some help please....

My Polo developed issues recently on a trip down to Jhb.

You can feel there is a rough idle, even with a warm engine.
You will be accellerating and then it jerks, mostly happening between 4th & 7th.

Diagnostic says:

-Cyl 2 Misfire detected
-Hide Cylinder

After a reset of the errors

-Cyl 1 Misfure detected
-Hide Cylinder

So no longer showed an issue with cylinder 2?!

Recent work or replacements
Plugs have been changed - VW Originals - 600 km old
HT Leads changed - replaced 2800km ago
New Battery - One day old ( old one was 4/12 years old and reading 12.4V even after a 4 hour drive)
Ignition Coil Unit - replaced 2800km ago

Is it common for the injectors to give issues??
