Will using an Porsche independent affect my manufacturers warranty?
Short answer is ‘No’. Since block exemption in 2003, the Motor Code of Industry Practice states “You will continue to benefit from the manufacturer’s new car warranty whilst the car is serviced to the manufacturer’s recommendations, even if this service is carried out by an independent service/repair outlet.”
Do you offer Courtesy Cars?
Yes, we can offer FREE courtesy cars, subject to availability. Please enquire at the time of booking.
Should we supply a courtesy car, we will require a copy of your driving licence and ask that you return the vehicle with at least the same amount of fuel as when you collected it.
Do you offer a recovery service?
Not at Present. However, we do use a local company that can recover your vehicle in the event of a breakdown or accident.
Further to this, if you are not a member of a vehicle national recovery service, it maybe worth checking with your bank? Depending on the type of bank account you have, most banks offer a vehicle recovery service as part of their banking products attached to your current account.
What engine oil will you use in my Porsche?
For new cars with petrol engines, we use Mobil 1 New Life 0W-40 fully synthetic engine oil.
For petrol water cooled cars, we use Mobil Super 3000 X1 5W-40 which is a fully synthetic engine oil.
For Cayenne, Macan and Panamera diesel engine we use Mobil 1 ESP 5W-30.
For all air cooled engines we use Mobil Super 2000 10W-40 semi-synthetic engine oil.
All oils we use are Porsche approved and in our opinion, the best quality and grade for your car.
How often should I change my brake fluid?
Porsche recommends the brake fluid in your car should be changed every two years. This is due to brake fluid being hydroscopic which means it absorbs water over time. Moisture build up in the braking system can lead to corrosion within the system and comprise braking efficiency. So even if you do not cover many miles between brake fluid service intervals, it is still imperative that you keep you brake fluid changes to manufacturers specification.
I have creamy yellowish gunk around the underside of my filler cap, should I worry?
This is quite a common occurrence and is due to short journeys whereby oil vapor and condensation hasn’t time to be recycled into the block and sump. This results in residue forming under the oil filler cap which looks like a creamy yellowish mayonnaise consistency.
If however, you see signs of the emulsion in the engine oil or in the coolant tank, then this could indicate head gasket failure, something which uncommon on the flat 6 engine as Porsche use metal head gaskets which prove to be very robust.
I've just put some fuel in my car and the fuel gauge hasn't registered.
If you own a water cooled 911 four wheel drive model, then your car has what’s called a saddle bag fuel tank design to accommodate the front differential on the vehicle. If the fuel light was illuminated at the time you put fuel into your car and you only put a small amount of fuel in, then the fuel gauge will not read the fuel that you have put in. You must ensure that enough fuel has been pumped into the tank so that both chambers of the saddle bag fuel tank have fuel in them. At this point, the gauge will read correctly. This is not a fault which needs rectifying, rather a characteristic of all 911 four wheel drive models.
If you have a two wheel drive 911 or any other model of Porsche and you are experiencing this problem, you will need to book the car in for diagnoses.
I don't use my Porsche often and the battery keeps going flat.
This is a very common problem for Porsche owners who only use their cars occasionally. All cars left standing will drain a battery, especially more modern cars that have complicated electrics and alarms/immobilisers. Also, the shorter the battery lead from the engine to battery, the better. Given Porsche sports cars have the engines to the back/middle and the battery in the front, they experience a bigger voltage drop when cranked. So after a few weeks, starting your Porsche will prove very difficult.
The best solution, if possible, is use a trickle charger to keep your battery in good health. A trickle charger will also prolong the length of time that the vehicle can be left without any starting issues.
I can't open the car off my key fob after several days.
If you do not use your Porsche for 5-7 days (depending on the model), the car goes into sleep mode to save the vehicle’s battery. This means that the cars remote control module is disabled.
The process for gaining access to your car once in sleep mode is as follows:-
1. Unlock the driver’s door with the key and leave the door closed in order to prevent the alarm from sounding.
2. Press button 1 on the key fob or turn the car on at the ignition to wake up the car.
Your remote control key fob will now work again.

I have been very impressed with the level of service that Cavendish have given me whilst maintaining my Cayman S. Also, their knowledge and enthusiasm for the brand gives me confidence that I have chosen the right Porsche specialist to look after my car. I would certainly recommend them to other Porsche owners!Tim Marshall
These days it’s hard to find a good Porsche Independent you can fully trust. I have been using the technicians at CavendishPorscha for over 5 years, even though it’s over 15 miles away! They carry out faultless work on my Porsche 964 at very reasonable prices. I would highly recommend them to anyone. Great work, keep it up.Martin Cook
It was September 2017 when my 1990 Carrera 2 Targa refused to start, so I looked for a good Independent Service Agent locally.
After reading the testimonials at Cavendish Porscha I was confident to entrust the repairs to them. It turned out that a raft of issues were uncovered and as result they stripped and rebuilt my engine. We talked of my selling the car and I agreed to let them take care of everything.
Well, they did - Simon supplied stage by stage photos of progress and I went to see the finished car and was extremely impressed by their attention to detail and honesty during the repairs.
Adam and I agreed a price and the car was sold almost instantly. So I cannot recommend more highly, the efforts, professionalism and high calibre of workmanship at all levels.
Thanks again to Simon, Adam and team
Prior to using Cavendish I used another well known Porsche independent in the Nottingham area.
My first encounter with Cavendish was after experiencing a strange noise from my engine, I took my 911 along to my usual Porsche independent to investigate. After a day had past, I received a call from them telling me that my engine had failed and that I needed either a full re-build or replacement engine at an approximate cost of £5000-£6000. Not being convinced with their diagnosis, I took my car to CavendishPorscha for a second opinion. I told them nothing except that I had an unusual noise coming from the engine.
A few hours later Simon called me to say my car was ready for collection and all is OK. It turned out that a spark plug was loose (fitted by the garage that told me I needed a new engine) and the compression from the engine was blowing past the loose spark plug and making a peculiar tweeting noise….. £45 later, I was back on the road!
I have used Cavendish ever since and this is down to their honesty and experienceMark Harrison
My GT3 developed an engine oil leak so I took it to my local Porsche independent dealer who had sold the car to me and had maintained it since I purchased it from them. I asked them for a diagnosis and a quote for repair. A few days later they called me to say they had found the problem and that the rear crank seal was leaking and it was going to cost around £1,100 to repair. I requested that they hold fire whilst I thought about it!
I decided to get a few quotes for the repair from other local Porsche indies. By luck I called Cavendish and explained what I required and gave my vehicle details. To my surprise they told me that my 997 GT3 was in fact at their garage and on their ramp waiting for authorisation to carry out the repair to the rear crank oil seal! My dealer had taken it there without my knowledge and had led me to believe that they would be carrying out the repairs! So, I asked Cavendish how much they had quoted to carry out the work and I was told £450 which also included the VAT.
After my conversation with Cavendish, I gave them the authorisation to carry out the work. I contacted my original Porsche specialist and asked them to explain. Obviously they couldn’t!
Due to the honesty and workmanship carried out on my car, I have used CavendishPorscha ever since. I would recommend them to other Porsche owners looking for a very reasonable price and honest service.Gavin Haywood
Cavendish Porsche has been looking after my 1987 944S since 2013 and in that time it has gone from routine maintenance to major top end rebuild. My Porsche has now covered a massive 297,000 miles and she’s still going strong which is a real testament to the quality of the brand and to the workmanship that has been carried out over the years.
I’ve always been delighted with the friendly down to earth service that I have received and I will always use the team at Cavendish for all my Porsche service work.
Being new to Porsche these guys really explained things well, very happy with the service , will definatly be using them going forward. Very honest with the work carried out, could have up sold me a flywheel but said don\'t bother it\'s in great shape. Honesty is hard to find in this trade!James Henfrey
