indeed. if you manage to explain it to your wife and she conveys it properly to them i am sure there will still be a confused look at the service desk.
Hmmm...engineering chinese-whispers from an accountant through a HR person to a technician/fitter...it's got SO many possibilities...we could end up being told to use AutoGlym!!!
Neil,
the solution looks like the Wynn's product. What is a shame, is that nobody knew the product was out there. It was only by chance the coke was discovered and then the appropriate research all this came to light.
A few of us(RS4 B7 owners) were looking at gas flowing the inlet manifold and every car taken apart this could be seen.

Finally found it, not quite as enlightening as I thought, be here it is.

Cleaning of coked engine parts Release date: 19-Mar-2008
Customer statement / workshop findings
All petrol engines. Cleaning of coked engine components (for example: inlet valves, combustion chambers, injectors).
Technical background
Carbon deposits on injectors, combustion chamber surfaces and in the intake system can result in severe running problems following cold starting and in loss of engine power. Tests have shown that coking is mainly caused by fuels and oils with inadequate amounts of additives.
Production change
No change.
Measure
A range of cleaning processes were tested, with the help of which coking deposits can be removed. The most effective method was found to be the injection of a cleaning mixture into the running engine.
In this process, the vehicle is connected to an external fuel circuit using pressure container V.A.G1938 and a suitable adapter for the vehicle fuel pipe.
The pressure reservoir V.A.G 1938 is no longer available.
The cleaning equipment BEDI can be used instead. Please observe its operating instructions. The equipment is available from:
R.U.F

The cleaning procedure is performed with the engine idling and takes about 30 minutes.
In testing a range of cleaning agents, the best application results were achieved using products from the following manufacturers:

Fuel additive for petrol engines, available under - Part No.: G 001 700.03
The cleaning agents have been developed specifically for the removal of coking deposits. There are slight differences in application and in cleaning efficiency.
In the case of combustion chamber coking (e.g. inlet valves) slight advantages were evident when using Wynn's Lambda Global cleaner
and Part No. G001 700.03.
In the case of coked injectors (reduced injection quantity with mileage), there was an advantage to using the cleaner from Carbon Clean.
• Important application instructions: The instructions of the cleaning agent manufacturers must always be observed! An engine oil change must be performed following the use of cleaning agents!
With the exception of Lambda Service Tank Otto and Part No.: G 001 700.03, the addition of cleaning agents to the petrol tank is strictly forbidden!
The preventive use of cleaning agents cannot be invoiced under warranty.
