Your Porsche 996, 997 or 991 is in the best of hands at JMG Porsche, where even with servicing we go beyond the factory schedule.
The factory schedule for many models called for a service every two years, which was fine when the car was new and to make the car last beyond the factory warranty without issue. However we strongly recommend that all models are serviced annually, alternating between a minor and a major service each year. Click here and read our article for more information.
Here is a breakdown of our servicing (Phone for Turbo, GT2 and GT3 Prices).

All services are performed with Porsche approved Quantum/Fuchs oil and genuine OEM filters.
The importance of routine annual servicing.
Routine annual servicing will benefit your car from being inspected by an expert every year, which will certainly mean that many problems are spotted long before they turn into an expensive problem, a simple seal for example, costing only a few pennies, could be all that needs to be spotted and rectified to avoid a complete engine failure.
Beyond this, on more modern models where the servicing is specified by the factory for every two years, there is evidence that that has decreased the long term reliability of components. A good example of this are the engine oil hydraulic components on a Porsche 997 being the same parts as used in a Porsche 996, yet the 996 rarely suffers from variocam solenoid failures, but those of the 997 are frequent and can cost thousands of pounds to repair, just for the sake of regular yearly servicing and oil changes.
Some people only cover a few miles per year and therefore believe their car will not need regular annaul servicing, however this also can cause problems.
We have many menu prices for Porsche repairs of each model which are usually likely to cost more if performed with our hourly rate, call us for a price.
For anything else our repairs hourly rate is £79.95 per hour.
Menu price diagnostic appointment - £149.20 (Two hours)
Porsche cars are especially sophisticated and complicated cars, therefore diagnosis needs to be performed by expert Porsche specialist diagnostic technicians, the cream of the crop, even for what might seem like very simple faults.
With all faults, there will be a problem, such as a bad relay for example, as well as this there will be a cause, perhaps this cause would be what caused the relay to become faulty, which in itself could be abstract or unusual, or could be as simple as age, but it is still important to be reasonably sure of the cause, before new parts are installed, otherwise the new parts will also swiftly expire!
Even with the most expert technicians it is impossible to predict what the fault may be, until we have spent some time both diagnosing what is faulty and what has caused that item to be faulty, so to be professional at what we do, in some cases we may need to spend a longer duration of time with our investigations.
Unfortunately, this can mean that diagnosis can be very time consuming and therefore expensive, as well as difficult to schedule in our busy workshop.
With this in mind we have developed a clinic system for diagnostic visits, where we charge £149.20 for a two hour appointment. During which the following will happen.
The customer will be able to talk to the diagnostic technician in person to explain the fault.
The diagnostic technician will endeavour to recreate the fault to experience it in person, perhaps including a test drive with the customer.
The diagnostic technician will then begin tests to narrow down the fault, which may include using the Porsche diagnostic computers, or even our special diagnostic equipment not available elsewhere, studying the engineering documentation, technical service bulletins as well as running manual tests on or off of a vehicle lift.
In the case of the problem being simple, it may even be possible that within this phase the problem may be found, the cause clear and perhaps even a repair made.
Once complete, before the two hour appointment is exhausted, the technician will spend time with the customer explaining what he has found, as well as what additional diagnosis may need to be performed, how long that may take, and what potentially could be the causes of the problem, concluding with an appointment made for when the further diagnosis or repairs can be made.
Between the end of this visit and the appointment for continuation of the repairs or diagnosis, the car can be taken away, or left with us by mutual agreement.

Interesting service and repair information for the water-cooled models.
Service interval - Some models specify a yearly service in the owners handbook, some specify two yearly, now that several years have passed since the first models with two yearly servicing were introduced we have observed that those models are more prone to needing expensive repairs, such as bore failure, valve actuator faults which we are only able to assume is caused by less frequent servicing. We would strongly recommend that all Porsche models are serviced yearly or every 10,000 miles to avoid expensive repairs and to potentially catch issues early, where they may be less expensive to repair.
Engine failures - Not nearly as common as horror stories on the internet would have you believe, but there are still worthwhile ways of avoiding unexpected large engine rebuild costs. One of which is proper servicing by a real Porsche specialist, which may not need cost as much as you think. There are also some ways to avoid unexpected bills by following some of our other advice bellow.
Brake fluid - Did you realise this should be changed every two years? Not doing this can cause problems with expensive parts within your car, such as the ABS pump or any part of the brake hydraulics due to water contamination as the brake fluid actually sucks moisture out of the air (hydroscopic), so even if the car is not used, the brake fluid must be changed every two years!
Water Pump - Often thought of as a part which fails with age, mileage and quite suddenly, leaving you stranded, our expert technicians are used to inspecting these during services, and so may spot tell tale signs of failure long before they become an issue, so saving you from the indignity of being broken down at the side of the road.
IMS Bearing - The famous intermediate shaft bearing (IMS Bearing) is an important bearing within the engine. These can fail on some models and cause catestrophic damage to the engine, sometimes costing thousands to repair. However there is a better design of bearing available, which our engine specialists at JMG Porsche have developed some cost effective ways to install and remove the risk of this kind of engine failure. Typically, the most cost effective time to replace this bearing with the better design is at the same time as a clutch replacement. However if you do not need a clutch now, or own a tiptronic model, then we can perform this job at any time.
RMS - Rear main seal - Something else you might see horror stories on the internet about, these used to be a real problem and Porsche re designed the part several times to arrive at the current design which is the only one we at JMG Porsche use. Like an IMS Bearing replacement, this is best performed during a clutch change, however on tiptronic models or on cars not needing a clutch, they can be changed at any time.
Transmission services - Not clearly noted by Porsche for when the transmission should be serviced and this vital expensive part of your car should not be overlooked. Just like your engine, the transmission is filled with oil/transmission fluid, which over time degrades. Not only this, but not many realise that many Porsche transmissions also contain a filter, which becomes clogged over time and can starve your transmission of lubrication, causing expensive repairs. We recommend all Porsche transmissions are serviced every 4 years or 40,000 miles, whichever comes soonest.
Diagnosis - Long has gone where cars had limited electrical equipment and a wiring diagram could be found in a manual from Halfords. Now the Porsche models have multiple separate computer systems, which all talk via networks, and many sensors to feed those computers with information about the world around it all tied together with many hidden wiring looms of thousands of wires and connectors. This can mean that in the event of your Porsche suffering an electrical issue, it is important that a Porsche specialist auto electrician is available, as we have at JMG Porsche. It is also important to understand that sometimes, finding the fault will not be as simple as plugging in a computer.
Air Oil Separator - If your Porsche is producing some smoke, especially when it starts up in the morning, it could be that the air oil separator has failed rather than your whole engine being damaged. This simple device is designed to allow your engine to pass polution regulations and should not cost the earth to replace, at least much less expensive than rebuilding an engine!
Drive Belt - Many of you may have had cars where a drive belt, timing belt or cam belt needs to be changed at a regular interval. Your Porsche model has a belt which should be changed every 4 years. Failure to do so can cause instant overheating, loss of power steering and damage to the engine very suddenly. We recommend you have this changed at least every 4 years.
Heavy clutch? - A heavy feeling clutch which is stiff to use is not normal on a Porsche and often a sign that the clutch has almost worn out. Ignoring this can cause further damage, such as to the dual mass flywheel and clutch fork.
Alarm system - At JMG Porsche we are experts of all Porsche security systems and have reverse engineered all the various control units. This not only means we can program new alarm control units and keys to your car, just as the main dealer can, but in some cases we can repair your old alarm control unit and keys, or in some cases recover your old keys to be used on the new alarm control unit, which is a service unique to JMG.
Alarm system causes - In most cases the cause of alarm control unit failure is water damage, we can perform modifications to your Porsche model to help mitigate the chances of this happening to your Porsche.
