Eliminates my cold start problems

Although my car is still quite young with his 6 years and only 50000km, stood before 20000km a cold start problems that caused a swing / sawing the idling speed and at very low temperatures the engine let go even immediately. Parts have been extensively replaced by the workshop - in the fault memory was no indication a problem.
By chance I came across this product and tried it immediately:
Already at the next start and a long drive, the problem was solved - he started as freshly rolled off! And so it remained. The problem was well apparently that had polluted the petrol supply and (the throttle, high speed) only at high pressure could flow through the fuel.

I had previously searched in many forums for a solution to my problem and my conclusion was: It is not vehicle specific, and each motor can get this problem. So before expensive parts to be replaced, you should just invest time 11 Euro here.

Anyway, I'm thrilled!
