EXHAUST GAS RECYCLE!.

Now this is a surprise. My car was with the Garage 3 days and in that time they diagnosed but didn't resolve.

Apparently my exhaust gas recycle path into the air inlet manifold is severely restricted by soot/filth....and on low throttle the air to fuel mixture is affected.
I didn't see the engine myself but have looked on You Tube and there are many descriptions of the issue and how it needs to be cleaned. They asked whether I had tries out Bio Diesel and how long my normal trips took. They are trying to understand why I started to have this issue only after a year.

They say it is a major work and they initially were waiting for approval from Porsche CH and they had to order a tool to carry out the clean.

This was 2 weeks ago and I am waiting for a date to carry out the work.

So I cannot yet say whether it solves the issue and for sure if it does I will want some assurance before my car finishes its warranty cover. If it is the EGR I am astounded it needs a clean so quickly and doesn't thrill me for the future. Lets see....
Thanks for the update. I'm under extended warranty so I will be getting them to look at it if it continues.

Please let us know the result.

Appointment to have the inlet manifold cleaned was canceled as they could not get hold of special tool. Its rebooked for the end of this month (October). Will provide update after the end of this month.
Fingers crossed !
