Your 924, 944 or 968 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.


 

Service interval - We strongly advise that all Porsche cars are serviced every year, with a major service every two years.

The service schedule can be confusing with some service items needing to be performed every X amount of years, with other items being specified every Y amount of miles.

At JMG Porsche we have built a database for each model car, where every two years of age for your car, has listed the major service it requires in that year, which combined with every year in between major services the car having an annual service.

This means that for your model of Porsche, we can provide you with a plain price list for servicing, no matter what year your car was made, which makes it easy to see what service items are due and what the total cost will be.

To get a copy of the current service guide and price list for your Porsche, just email us to have your copy emailed to you in PDF format.

Eventually we plan on making it possible to register to the website and be able to download the latest version of this price list - Watch this space!

 

Interesting service and repair information for the Porsche 924, 944 and 968 models.

Engine failures - Not as common as you would expect, we at JMG Porsche have never had to replace one of these engines due to wear, however we have had to replace many due to insufficient servicing and maintenance, 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. A 944 and 968 Waterpump is also part of the cambelt drive mechanism, so it failing can cause serious damage to the cylinder head and engine as a whole.

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.

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.

Cam and Balance belt - The 924S, 944 (ALL) and 968 (ALL) have a cam belt and balance belt, which has to be set to a very precise tension and run across various pulleys, tensioners and rollers to function correctly, if these are not maintained with a new cam belt and balance belt every 4 years, and a new waterpump, tensioners and rollers (as well as front engine oil seals) every 8 years, the consequences can be catastrophic to say the least.

Brakes - The Porsche 944S2, 944 Turbo and all 968 models are fitted with Brembo callipers, which overtime suffer from corrosion build up which can cause the pads to stick and bind up within the callipers or even make it difficult to fit new pads. When this happens the calipers require a service rebuild of the slider plate mechanism, which needs to be performed by a specialist with the right experience, techniques and tools to make the repair more than a very temporary one.

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.
