Put in a litre of anhydrous IPA 

IPA as in iso propyl alcohol or propan-2-ol

Sorry about that 2016 model GTi dsg pp. If beer then Riggwelter  by Blacksheep brewery is probably best to forget what the question was or even who you are !

Tesco fuel is no better or worse then Shell or BP, just cheaper, Years ago Redex and its ilk were of use in carburetor engines but can not do much in injection engines, Injector cleaners mightbe  of use in high milage engines but have little effect.

Engines with direct injection dont even allow the cleaning of the inlet valves as the fuel does not flow over the valves.

Not sure what car/engine you have from your post as you have not put that info in your signature - would help in future so people know what motor you are posting about

The Mk7 has a fifth injector in the inlet manifold.
The idea is to clean the valves and lessen the carbon build up that strangled the Mk5/6.

Yep totally agree in fact with the higher turnover of fuel at supermarkets I would think you would suffer less issues regarding contamination etc.  Used tesco in my 911 & there 99 stuff in my E63 V8 no problems
