Help Needed. Car running very rich.

I have sent my AFM and ECU to be tested at ATP Electronics https://www.atpelectronics.co.uk/
Should hear something today if they've found anything.
I know it’s better to find the cause than merely address the symptoms but have you considered moving the Fuel Quality Switch on the DME to position 2 (-3% fuel)?

I haven't done anything with the injectors as the car actually drives smoothly and I would have thought that if the injectors were blocked it would run lean and not rich.
I don't want to adjust anything to compensate for the fault as the car was running perfectly before this happened and if I can find the faulty part I won't need to adjust things back.
See you tonight if you're at the meeting.

Sounds like a typical Lambda sensor fault. Since you have already had the ECU checked seems to point even more to the Lambda sensor. Good look in getting the old one out if it proves to be this
Best regarda

I have one ready to fit but I'm not going to attempt it myself as it's really difficult to get at and as you say it wont want to come out.
You don't hear of other people having trouble with them on these cars which makes me wonder if it is that or not but I will get it changed at some point.
I've read that Porsche recommend changing them every 60,000 miles but I don't know if anyone does.
My car has done more than twice that.
A garage with an oxy-acetylene torch will have it loose and off in no time.
