My favourite Hatchback of all time view my channel for a very clean 2001 6n2 VW polo GTI build today got a sportex exhaust and ram air induction kit and sounds beautiful if anyone is going to buy a polo like this do look into lowering springs or coil overs it will make the car look and feel so much better through the corners and definitely worth getting some quality wheels even the stock alloys on the 1.4 s look very smart Overall a superb car and a brilliant first car for new time drivers especially in the UK
If you are sure that ICU is the problem you should visit electronics engineer who specializes in car electronic. He could take closer look at the problem.
