Your Porsche Cayenne or Macan is welcome; whatever the repair, whatever the issue, whether near new or an older model. We have decades of experience and are fortunate to enjoy facilities far above most independent Porsche dealers or normal service garages. Our modern premises are 16,000 sq. ft. of pure Porsche passion!

If your Cayenne or Macan is under a Porsche manufacturers Warranty, we can service it to Porsche standards, keeping your warranty valid by using all original Porsche components, procedures and diagnostics.

If your Porsche Cayenne or Macan is no longer under the Porsche warranty, we are able to recommend further solutions.

We offer significant advantages over an Official Porsche Centre, with a more flexible and innovative approach to many issues. These solutions are often more economic, but without any sacrifice to quality. We are not under a rigid manufacturer’s rule, therefore we can offer a broader range of repairs and upgrades that are beyond the options of a main Porsche Centre. It may be viable to repair a component rather than replace it. ECU’s, instrument clusters, steering racks, suspension, sound systems and trim can often be repaired. Some non-Porsche components are stronger or perform better than the original.

We serve Porsche owners throughout the South West and beyond. Is your Porsche in the Exeter area? Or North Devon? Further towards Truro or Falmouth? It’s no problem, we have many customers from these areas and can make servicing and repair really easy.

From our customers……

  • ‘Williams Crawford has provided the best support of any specialist that I have used during thirty years of Porsche ownership. The team elevates customer service to an art form! I would recommend Williams Crawford unreservedly for all things Porsche.’ Dr James W.
  • ‘Polite, professional and service completed on time, good Covid precautions in place.’ Christine S.
  • ‘Passionate Porsche specialists. Amazing stock and second to none workshop. I asked Williams Crawford to code a replacement key which was carried out at short notice and very quickly. If you’re in the South West and looking for a Porsche or need work carried out on your own vehicle, I would recommend checking them out.’ Orlando B.
  • ‘The company slogan is “Passion for Porsche” and that is just what you get. Brilliant service, friendly staff and first-class maintenance of my 911 and Macan. If only the franchised Porsche dealer for Devon and Cornwall was half as good, Sadly they are not in the same league as Williams Crawford who truly cares about looking after your Porsche.’ Julian W.

Porsche Cayenne and Macan issues….


Tiptronic/PDK transmission. The automatic gearboxes are generally strong, but like all mechanical components, there can be issues. Typically this might be a sensation of slipping, juddering or vibration. You may notice the feeling under acceleration or pulling away, when reversing, manoeuvring or turning tightly. In this scenario, make an appointment so we can quickly diagnose the problem. If it is indeed an internal transmission fault, failure can occur soon after the sensations appear. Repairing the existing transmission is rarely cost-effective or a long term solution. Our recommendation is to install a factory reconditioned and warranted gearbox.

Coolant leaks. Typically owners will first notice the low coolant warning light on the dash. Topping up the coolant level occasionally may be a requirement or you may notice the sweet smell of the antifreeze when the car is warm. Signs of drips of pink or red liquid are most likely to be a coolant leak. The most common issue is leaking coolant pipes on top of the engine. Let us diagnose and fix the problem before it gets worse or leads to overheating, internal engine damage or additional repairs.

Cayenne drive train noises. Are you hearing an unpleasant thump, clonk or vibration from under the floor? This is a problem where experience and independence pay off. We can offer a high-quality alternative and a far more economic solution than the Official Porsche Centre repair of a new prop shaft.

Petrol misfire. Caused by faulty coil packs. This may trigger a warning light and it can cause rough running. If you sense, feel or hear an unevenness or misfire, let us carry out a diagnostic test. Being independent, we can offer either Porsche brand components or an OE quality replacement coil pack at a significant saving. Ignoring the issue can lead to damage to far more expensive components such as catalytic converters.

Xenon Light failure. Your fault could be simply a bulb, which is an easy fix. If not, it’s often the ballast resistor mounted under the headlamp unit. We can offer both the original Porsche branded unit or a quality alternative.

Engine warning lights. Any engine warning lights need investigation. We use the latest PIWIS (Porsche Integrated Workshop Information System) diagnostic. Many garages chase faults using lesser equipment, wasting money on new fitting components when not necessary. With our diagnostic tools, we have a high chance of efficiently identifying the issue before continuing with a repair.

Water drains. We recommend that the water drains are checked and cleared at every service. It’s a small cost and one that is often overlooked, but can prevent major problems and major costs. We modify the drain to discourage future build up. Water ingress can be slight or serious. From damp footwells, causing steamy windows to flooded ECU’s (electronic control unit), causing random engine management warning lights and possibly complete failure of the system. Porsche Cayenne models with sunroofs have four additional drains which require extra checking.

Cayenne Suspension noise. These cars are very durable, but some have been on the road for a long time. If your Cayenne clonks, knocks or squeaks, bring it in to be checked. Worn bushes on the front suspension arms are often the cause. We typically replace the whole front suspension control arm, complete with new balljoint. Again, there’s a choice of genuine Porsche components or OE quality parts. Once fitted, we use our Hunter laser alignment system to perfectly align all four wheels to manufacturer settings. Continued use of a worn suspension arm can cause premature wear (often the inside edge) of an expensive tyre, poor steering, poor straight-line stability and cornering.
