911 Servicing tailored to your requirements

The Porsche 911 has evolved since its introduction in the 1960's. Each model of early 911 has its own idiosyncrasies which require specialist attention. Various injection and ignition systems have been used in this era, each with their own specialist tooling and equipment to maintain and tune. At JMG Porsche we are familiar and equipped to deal with with both the last 993 through to the very first 911 and 912. This includes the Turbo variants or even the 70's RS.

Selecting the correct service for your Porsche can often be a confusing task for those who do not deal with it every day, more so if you only cover few miles per year, so we tend to recommend that when you need servicing ask us for our advice, we will be more than happy to ask you a few questions and reply with the ideal service for your Porsche.  If on the other hand you are sure which service you would like performing from the factory schedule, we are also more than happy to do so.

As part of the service your car will be inspected beyond the usual items listed by Porsche to be inspected. Should we find any problems, we will try to call you so it is important to make sure you are available by telephone and if you are unable to answer our call, to call us back as soon as possible so we can discuss the issues and if need be, so you can authorise any additional repairs.

These following prices apply to all models except the Turbo, Please call for these models.

 

Minor service - £295.20*

Major service  - £495.20*

Brake fluid replacement - £59.10

Including all parts and labour

 

Repairs at a reasonable hourly rate of only £79.95 per hour for cars over ten years old

 

911 Models over ten years old are considered as classic cars and as such in our ongoing commitment to keeping older Porsche cars on the road, we discount their hourly rate to what you see above.

* Servicing includes all parts and labour except for the cost of additional fluids which are only specified to be topped up in the factory service schedule, such as screen wash, or for additional parts or labour not usually required to complete the service, due to corrosion or other damage.

All prices are plus VAT at the standard UK rate.

Interesting service and repair information for the air cooled 911 models.

Service interval - The factory service manual specifies the air cooled 911 models however some owners are tempted to have their cars serviced infrequently due to low mileage, however this is very dangerous and could allow the build up of contamination and water within the oil system which can be corrosive to the oil tank and internal engine components. 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 of top end rebuilds being required every 130,000 miles 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!

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.

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 or belts which should be changed every 4 years. Failure to do so can cause instant overheating, loss of alternator charging 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 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 (late models), 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. For all air cooled 911 models we can bypass the original alarm system and install more modern alarm systems in their place which are Thatchum (insurance standard) approved.

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.
