Hello all.
Some time ago I assumed the topic after my Polo just stopped firing after the weekend. Out of the blue, the engine wanted but could not. It clicked by a few turns and then went out.
After a long search for a problem in the ignition system, in the fuel supply, even in the engine controller, it turned out that the catalyst was to blame.
The catalyst, after a long route on Sunday, and a strong warm-up, apparently made a life, and when it cooled down overnight, you could say "collapsed", crumbled, clogged completely, and completely blocked the exhaust outlet, causing the engine to choke.
To the point now - the mechanic took the catalyst on an ad hoc basis and treated it with a drill (cleared it) - a rather vague but effective solution so that I could drive the car until I decide what to do next.
There are two probes in this polo, in front of and behind the cat. The mechanic warned that errors of the latter may pop up, so additionally "blah blah blah and here I did not understand" he modified the probe to avoid errors from the computer. And he only took PLN 150 for everything.
Well, let me tell you that I have been driving this way for 2 months, the car has a much better kick (as if he had a dozen or so horses), maybe it smokes a bit more (maybe 0.5l more) and no errors popped up, neither the engine light nor probe or exhaust error (strange?). I have already driven something in the range of 1000-1200 km.
Unfortunately, during this time, the volume of the entire exhaust increased significantly (not only immediately after repair, but during use).
I will mention that I do not have a KAT anywhere in the registration certificate.
My question - in this situation, could it be possible to throw away the entire can of dead catalyst, simply replace it with an elbow / piece of pipe? Because I have the impression that this empty metal can of executioner gives even more buzzing publicity than a simple, uniform pipe would give.
You can possibly add a spotlight or a small intermediate muffler to mute the entire exhaust?
I only have one doubt in principle - what to do with the second probe (and what actually did the mechanic do with it, because he did not want to say). Screw both probes one by one into the same pipe? No sense?
