My at dealer from the 31st of OCTOBER 2016

<p>My car has been with Volkswagen Lenasia for the past 6 months. I am not getting proper answers as to what is aheppening and I am always getting different stories. I am at a point where i cannot even trust the worfk they are doing in my car. They have been guessing for a very long time as to what is the problem. Thye have overhaulled the engine,skimmed the cylinder heads,took the computer box for diagnostic,repalced the ignition coil and spark plugs but the problem was still there and all that work happened in different days and months. they have lattelly told me that it is the engine control unit which I dont know to what degree must I trust that it is really the problem. Please help me in this problem.</p>
