I just recently took my Volkwagen Tiguan to Edmonton Chassis for a 2nd opinion as the Volkswagen dealership (South of 137 Ave) indicated that my vehicle was at their shop months prior (from previous owner) and that they ran a diagnostic and also that they changed the oil sensor on the vehicle, and that tech came to the conclusion that my now owned Tiguan needed a new engine. Dave from Edmonton Chassis was very friendly on the phone and professional as I explained to him what the dealership service had told me. Dave said to bring my Tiguan and they will run a full diagnostic to really determine whether the vehicle in fact needs a new engine. As it turned out, the engine is very good and that it only needed a new oil sensor (the one that the Dealership indicated they've changed in the past - which is not even an OEM because it's a Mitsubishi oil sensor which was faulty on my vehicle). Suffice to say, always get a second opinion before listening to the dealerships recommendation (which is often a money grab). It could save you thousands and thousands of $$$. Better yet take it to Dave from Edmonton Chassis, you wont be disappointed.
