New tcu cost $1200 I can get a used one for $200 The #'s on mine are A022 545 16 32 EGS51 5Wk33960 98W30 Others I look at are the same year and model but #'s are a little different. For instance the 16 may be a 23. Will this work and does it need to be reprogrammed at MB? Any help would be appreciated.
