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 [...]
With only 22,000 miles, rodent damage on the ABS rear wheel speed sensor data cables. Somehow a mouse found its way inside the car, under the seat, under the carpet, under the foam padding, and into the rear wiring harness conduit for a quick snack. Required extensive work to diagnose and then removal of the passenger seat and carpeting to service.
A fun and rewarding job, installing a stainless steel sport exhaust on a brand new BMW M3 coupe. Looks pretty and sounds even better!
Audi/VW timing belt replacement is a bit of a project as it requires the removal of the front nose of car. When replacing the timing belt it is critical to also replace the engine water pump and thermostat as they are located behind the timing belt, requiring belt removal to access. Not the most technician friendly design. It is also strongly recommended to replace the tensioner roller, serpentine belt and inspect the tensioner seals for oil leakage.
A/C Evaporator Core Service, requires extensive dash removal. Car suffered repeated loss of refrigerant, testing dye did not indicate external leakage but internal to dash. Note the yellow dye stains on the removed evaporator core, lower right photo.
Engine oil leakage from timing chain tensioners. Previous service facility had replaced the timing belt but not checked/serviced the tensioners seals. The new timing belt had been ruined by oil leakage and required replacement. Continued use of the car with the oil leakage and damaged timing belt would have resulted in severe engine damage. The timing chain tensioner seals should always be inspected for leakage during timing belt service.
Failed engine water pump, requires removal of the front nose of car. The engine water pump and thermostat are located behind the timing belt, requiring belt removal to access. Not the most technician friendly design. Always replace the water pump and thermostat when servicing the timing belt.
Failure of clutch release bearing damaged TDC pin in flywheel. Early replacement of the clutch release bearing would have avoided this expensive failure.
Aftermarket HO2 sensor spliced in by previous servicing facility, note nylon wire tie securing to sway bar! Any wonder why the Check Engine light was on? That's why we use only Original Equipment parts on our client vehicles, aftermarket parts cost both the owner and workshop time and money.
Water entry into trunk filled and damaged the pneumatic body control module. Believe it or not we were able to repair this unit, saving our client hundreds of dollars.
