Anyone considered Terra Clean?

This process is available for both petrol and diesel engines.

Something I'm considering doing to my Audi A6. She's now sitting at 95k miles and is running fairly sweetly to be honest.

I have recently replaced the fuel filter and also removed the EGR valve and decarbonised that, I stopped short of removing the intake manifold though so I'm sure I could still see some benefit from this.

I know of a few friends from my Jaguar forum who have had this done and say great things about it. One in particular is taking his wifes car, his brothers and his Father in laws back to be done.
At a cost of around £70 it definitely sounds worthwhile to me and won't break the bank.

Unfortunately demand is so great right now with still only a few dealers set up that it may not happen tomorrow.

Anyone any thoughts on this?
