Computed from DVSA MOT results, all of Great Britain, 2025. Nothing here is opinion.
Share of tests where each item was recorded. The dark tick is the class average across all tracked models; bars are scaled within each group.
The rows that judge the model rather than its keeper. 17,459 tests in this band.
Tyres, pads and stone chips say more about how the car was driven and maintained than about how it was built.
Owner folklore from forums and the motoring press. Most of it never shows up in an MOT, which is why this section exists at all.
The Porsche Traction Management transfer box can develop a shudder or hop when pulling away gently, or a clunk when reversing up an incline, most noticeable at low speed with a cold box. It's a well known weak spot on early Macans, and Porsche has quietly extended the warranty on affected units to 7 years, fitting a revised transfer box under that cover. Outside warranty, a replacement runs to roughly £2,000-3,000.
Cars fitted with the optional adaptive air suspension can develop a slow leak in an air spring, which forces the compressor to run constantly until it burns out, often flagged by a 'chassis system fault' warning and one corner sitting visibly lower overnight. This model's measured MOT data flags suspension as the standout failure category, and air-spring and compressor wear looks like a real part of that, on top of the ordinary bush and drop-link wear any Macan gets with age. A compressor is roughly £600-1,000 to replace, an air spring similar again, and none of it is covered by a recall.
The PCM system, especially the 2014-2018 PCM 3.1 unit, is prone to a frozen touchscreen, spontaneous reboots, and a navigation map that spins on 'loading' and never appears, with the unit's internal mechanical hard drive taking the blame as it ages. It's an annoyance rather than a safety fault, but a dealer hard drive or unit swap is roughly £300-600, and there's no acknowledged fix beyond periodic software updates. Some owners of newer facelifted cars report the same symptoms, so a later Macan isn't automatically clear of it.
The plastic water pump and thermostat housing on the four-cylinder 2.0 engine is a recognised weak point, with the shaft seal starting to weep coolant as it ages, sometimes with no warning light before the temperature gauge starts climbing. It tends to appear from around 30,000-60,000 miles, and Porsche has revised the part more than once without ever badging it as a recall. Expect £800-1,800 at a dealer, less at a good independent.
The S Diesel's EGR valve can jam or strip its internal plastic gears, and the DPF clogs early on cars that mostly do short runs, bringing on power-loss warnings and the need for a forced regeneration or a full EGR replacement. UK owners describe it as hit and miss: plenty of diesels never see an issue, a minority need repeated intervention. Budget a few hundred pounds for an EGR and regen, considerably more for a new DPF.
