Thorough Maintenance Solutions

It is important to get your Porsche vehicle serviced in accordance with the manufacturer's  recommendations. This can help get the best out of your vehicle and extend its life. We only use approved fluids and parts at predetermined times and mileage intervals which are specific to your car's model.

Reliable Diagnostics

Whether you have a "check engine light" on or have any subsystem of your Porsche giving you a warning light, we can properly diagnose the problem in a timely manner. We have the latest diagnostic equipment that can access all systems on your Porsche. From software updates to coding modules, we have you covered.

Intermediate Shaft (IMS Bearing)

Our professionals have extensive experience and training involving IMS bearing replacement. Each Porsche goes through a pre-qualification procedure that includes dropping the oil sump plate, and several other procedures to identify any potential issues that might hamper the longevity of the new IMS bearing prior to installation.

Remote Key and Immobilizer Coding

A simple device such as the ignition key serves multiple purposes. For Porsche vehicles, the key itself is an integral part of the vehicle's diagnostic system. It serves as a remote unlocking device as well as a means for the on-board ECUS to recognize authorization to start. The keys need to be programmed into your car using the specific diagnostic equipment. You can count on Dumont's LLC to do that for you. Because of how imperative the ignition key is to your Porsche, we recommend that you have two sets of working keys for your vehicle.

Pre-purchase Inspections

It is necessary that you get your Porsche inspected before purchasing it from the second-hand market. There are often hidden underlying issues with vehicles that go untraced by an untrained eye. Contacting the professionals at Dumont's can help you make a wise decision and save you from the possibility of a financial mess.


We perform complete Porsche suspension overhauls, service, and repair including alignments to factory specifications or set them up for track events.

Engine Rebuilds

You can even count on us to perform complete engine rebuilds on all Porsche models from the early 356 to the latest water-cooled models.
