So I'm not sure how this works but I have a 2004 Jetta and I purchased a good uses EMC and had it reprogrammed with key and now I'm told that if the EMC I got came out of an automatic and I have a manual or vice versa it won't work, does anyone know if this is true? Oh and btw the EMC does have same serial number. Thank you Reina 2004 vw Jetta 2.0L
