Electrical Issues – Telling Simple From Not

This vehicle was sent to us by another repair shop with the concern that it did not start, or would only start intermittently. The battery, starter, and finally the key switch were replaced in an attempt to get it to start. In fact, the starter was replaced twice. Then it was towed to our workshop. Mystery? Had the battle is recreating the problem, which it did here. Mystery? Not really for the Atlantic Motorcar Service Team, we see these cars day in and day out, we specialize in knowing, not just guessing. And when you do the same thing again [...]

VW Passat Heater Core Replacement – Clogged Core – Low Heat

A heater core is a radiator-like device used in heating the cabin of a vehicle. Hot coolant from the vehicle's engine is passed through a winding tube of the core. Fins attached to the core tubes serve to increase surface for heat transfer to air that is forced past them, by a fan, thereby heating the passenger compartment. The heater core is made up of small piping that has numerous bends.Clogging of the piping may occur if the coolant system is not flushed or if the coolant is not changed regularly. If clogging occurs the heater core will not work [...]

VW Passat – Engine Damage – Use Of Non-Synthetic Oil

You'll note the severe scoring and wear on the camshaft bearing caps on the Audi/VW 1.8 liter turbo engine. Audi and VW strongly recommend, and in some cases require the use of a full synthetic engine oil in their cars. No where is this more important than in the engine which use a turbocharger. Non-synthetic, or low quality engine oils will break down under the load, carbonize, and cause internal engine damage or turbocharger failure. This is why we always suggest the use of a full synthetic engine oil in model years 1999 or new. The oil does cost more, [...]

VW Passat TDI – Engine Damage From Incorrect Oil

But why do I need to use "expensive" Synthetic oil the customer may ask. To which just one of these photos should be worth a thousand words...or a couple of thousand in engine damage. The sad thing, is that this could have been avoided, with a little care, and the proper synthetic engine oil. This Passat has a very unique engine, one of the early VW ""Pumpe Düse" design. Developed by Volkswagen in conjunction with Bosch, Pumpe Düse means "pump injectors" (though "pump dooz" is more fun to say aloud). The electronically-controlled injectors are located at each cylinder where they [...]

VW Passat V6 – Engine Oil Sludge – Incorrect Oil Grade Used

Engine oil sludge does not just affect Saabs, take at look at the oil pan and lower engine on this VW Passat. That black gooey substance is not tar, but engine oil sludge. Unfortunately the car was switched over to a full synthetic engine oil too late in its life, for the first three years it was run on a conventional oil, you can see the results. It is cheap insurance to always use a fully synthetic engine oil on all European autos newer than 1999. We use Castrol Syntec in our workshop, it is the factory fill on many [...]
