Hi wondering if the enthusiasts can help me. Own a3 1.9 tdi 2001. basically its idle at times (stick vaines?) especially on hills with full acceleration. Read on forum, power booster spray (also known as air inlet spray cleaner)to be sprayed on to inlet after maf or unit control arm and let it run in to turbine housing...under diagnostic it came up with error 17965 posotive pressure deviation problem.

stated in forum -
IIRC in england it is called 10k diesel booster,,,
What I fear is the debris falling into the engine or getting stuck with the valves,,,

so im worried if the spray will go in to debris and wondered if you had any knowledge towards the above.
