Private purchase Golf Plus // Defects directly after purchase // Gear damage and not accident-free

Hello you love Lyncht me please not because of stupidity I bought a used Golf Plus TSI 122 HP from Private. At a price corresponding to the age and supposed to the condition. According to previous owner accident-free and engine as well as transmission 1A. Stand also so in the display. Also the view into the engine room and the test drive were unobtrusive. Likewise gap measurements and – with amateur view – the painting. Then shortly after purchase without suspicion to the used car check from the ADAC around me times a bi The result was: left side was repainted, back door and tailgate – so not accident-free as stated. But not tragic at first. Then next to a few small things was criticized: engine leaks in the back. I am in the workshop to check. Diagnosis finally: Differential in the bucket and therefore orbitant oil loss. New gearbox + clutch + flex tube must be here. Approx. 2000 Euro all-in. The oil loss can almost not be done to the previous owner. The previous owner is a trained mechatronics engineer, at least he told me that. He was competent in any case. The ***** My question: Do you have experience, whether it is worth it to turn on a lawyer – without legal protection? What I am trying to do for myself is: gearbox or clutch would certainly have caused problems at some point anyway. This is now at least possible. now only the engine can provide for nasty surprises. But runs as far round as possible and is apparently also dense.
