P0489 - Egr liian auki
P0409 - Egr jumittunut kiinni.
Eli varmaankin karsoittunut jumiin jos ei muutenvaan rikki. En nyt ulkoa muista onko tuossa kyseisessä mallissa minkälainen ratasveto tmv. liikuttamassa läppää/luistia - nekin voi hajota.
Hattuvakiolla kuitenkin sanoisin että umpikarstainen on ainakin. Jos sen sieltä esiin kaivaa, niin selvinnee aika helposti missä mättää.
Maksullisella työllä ehdottomasti uutta tilalle, itse tehden pesu voi olla hyvinkin kustannustehokas vaihtoehto.
