I recently took my 2003 VW Passat to Ringtec because it was running rough. Paul quickly diagnosed the problem as a blown coil. He advised me that he ought to replace all 4 coils and all 4 spark plugs. He told me exactly what he was going to do, he told me how much the parts and labor would be, he did exactly what he said he would, he charged me exactly what he said he would, and my car was ready when he said it would be. All these seem to be a rarity in today's world. He was accurate, professional, courteous, and honest. I will take my car to Ringtec for all my service needs. I highly recommend Ringtec for VW service.
