FYI I am the owner of a van that was in a frontal. I knew this I purchased it on auction- Company fleet vehicle, driver had some backyard dude fix it up to hide the damage, but the stealership kept reporting the engine management light coming on. After stripping the front I found out why... exhaust took a knock, severing the wires to the lambda sensor on the exhaust and the numbnuts at the stealership could never find it. I fixed that, replaced the aircon evaporator because that was completely fukked... and she goes like a dream.
