TüV-examination before maturity

Hello colleagues from MT, I have been standing in the garage for some time (December 2013) a Renault Clio B/C57 year ’96. The badge of the TüV is still valid until April 2015 (i.e. about a 3/4 year). However, because of the age and the relatively long service life, I fear that the vehicle is no longer in such a good condition. Therefore, I consider whether it makes sense to present the car in an initial way at the TüV. Since I do not have a suitable other forum I have found myself here (at least this comes from the vehicle closest). Can someone answer me from my own experience a few questions: -Do I get a full 2 years new TüV if the review is positive? Back date to the last TüV would be meaningless, because in April I have to show the car either way – if the vehicle has defects (low or substantial, but NO TRANSPORT SUSTAINABILITY) then I am forced to show the car again before April Is my car even closed down if such defects are found and I do NOT appear to be a follow-up? -What has to be done according to experience if the FZG has not been moved for such a long time? Unfortunately, the battery is dead, since I forgot to disconnect the mass. But will be fixed either by charging or replacing it. I thank you already in advance for your competent answers according to experience! Greeting Chris
