Accord Tourer 2.2 Bj 2004 Krummer???

Hello all, drive now in the 3rd generation Honda (Civic, Accord Limousine, Accord Tourer)……. have bought the Tourer (Diesel) 2 weeks ago and now has to realize that the interior smells relatively strongly of exhaust gases……….I assume that it is the exhaust manifold……does anyone have an idea of you? If I have informed myself correctly, could this be a small weakness of the Tourer or? I also have a 2nd question: The driver door can neither be closed nor opened with the remote control…….can this be on the engine of the lock? Thank you for your help MfG Marcus
