No support to customers for common VW problems!!!

To whom it may concern<br> <br> I've been driving my 2006 Volkswagen Polo 1.6 for the last 4 years. Ever since I had the Polo the rpm never stays constant. There's a slight shudder from the engine every 4-5 seconds when it's hot and one even feels the engine shake for that second on your seat. Now 4 years later and it has become worse like every second, the engine sounds sick and there's a loss in power. After getting advise from numours VW in house mechanics and certified auto electricians, I changed the following parts<br> - Ignition coil <br> - HT leads for spark <br> - New spark plugs every service<br> - New Cam sensor<br> - New Lambda sensor<br> - Re-set timing<br> <br> After changing all those parts, it's actually worse now. After doing ALOT of research from overseas websites and local website, the coil packs, leads and engine shudder is a common problem and VW does not help their customers at all. The customers has to fix their own problems even though it's a common VW fault. This is really unacceptable from VW. I've spent to much money and I need VW to fix this problem without charging me. VW fix these problems without making any excuses. It's just more than fair that you start looking after your customers realy
