Moin people, from the above test system I ordered the Handpumep and only Lid 12 (should fit for Opel) then Lid 21 (should fit also for Opel) But unfortunately no one fits the lid properly. The 12 can be written down, but it simply does not close properly, so that I can not check any tightness. I tried this on two different Corsas B. Has anyone had similar experiences ? Is there another lid of this set that fits the Corsa ?
