The R56 MINI was the golden era of automotive fun and freedom on the open road away from emissions and electric power. The MINI brand was thriving with its quirkiness and off the wall marketing push, which made it a global success given its British icon status in fashion and on the road. Like with anything glamourous there was another side with faults and reliability woes plaguing owners in all markets, but this didn’t stop fun as it broke sale records for the 4 wheeled icon rebirth with model variates.

Having been an R56 MINI owner for nearing on 10 years I do look back at the best and worst of times as decade comes to a close. My R56 JCW has love and death of me at times when it repairs bills and maintenance but that has stopped me for loving her the way I do with the smiles, memories and friendship along the way. The R56 has taught me a lot about cars, engines, car upkeep and mechanical sympathy the older she has got with age as the mileage has gone over 125,000 miles which is 5 times around the world.

Let’s get down the business and discuss the common faults with the R56 as it has become a modern classic:

N14 Engine – It has its issues, but it always boils down to how the previous owners to look after with preventative and routine maintenance. Check the oil and filter was changed a minimum of every 8-10,000 miles or every year. If you have tuned/mapped it you will need to more regular oil and filter changes at 5-6,000 miles if you like your pistons ring not to wear out or scoring the bore in the engine’s cylinders. I made a video on how to look after it, which is available on my Youtube Channel

Timing chain – It’s meant to last 100,000 miles but will be needed to be done at around 50 to 80,000 depending again it’s usage and owner maintenance. Signs of it will need to be done is high tapping noise, and rattling sounds like a diesel engine on cold start-up, and lack of go from the offset with the noise disappearing as the engine warms up. It will cost around £700 to £1000 to get this sorted from an independent or dealership

Carbon Build Up – A common issue on direct injection due to the way the fuel doesn’t go over the values to clean them compared to the old port injection. The plus was better fuel economy and power but carbon build up the valves was an annoying by-product. It will need decoking every two to three years to keep running right which set you back around £200 to 250. You might think oil catch can save you from this problem after all the youtube videos but it doesn’t sadly as the PCV system was poorly designed anyway so all it is doing is slowing down the process…

High-Pressure Fuel Pump – Common issue on MINI which is annoying as they seem to last between 50 to 60,000 miles before they fail so its £600 for an OEM one. The same issue plagues BMW’s of this era as the 135i has this issue with HPFP failing on them too

Valve Steam Seals – Common german car issue as the rubber seals perish over time allowing excess oil to enter the combustion chamber. Check for blue or white at idle or full throttle which will show either the turbo is on it’s way out or valve stem seals need to be done both are expensive jobs at £1,000 or £600

Engine Cover Weep – Typical German car problem which happens overage as the rubber gasket perished so its £150 for this job or if it’s the whole cover then another £300. On N18 engine cover melting is a common issue at the corner near the turbo

Turbo Oil Feedline – This issue because the MINI engine runs so hot as it leads to oil feedline to leak or coke up so make sure it has the recall oil feedline heatshield or buy the aftermarket braided oil feedline at £80 and £180 fitting

Water Pump & Thermostat – On an engine that runs quite hot any way you would think they would give it a good cool system but that’s not the case as they regularly fail as they crack or the rubber gasket fails – the joys of the plastic parts on modern cars compared to metal items of yesteryears. The water pump is £35, and the thermostat is £75 which is a bit awkward to replace so another £200 there easy

Bushes – You buy a MINI for it’s handling so expect the bushes will need replacing unless the previous owner has replaced them to poly bushes ones. Bushes are cheap at £40, but it costs four times as much to replace on given the hours of work going into replacing them at £300

Clutch – As MINI are brought to driven so the typical check of seeing how high the biting point or any whine from the front from the dual mass flywheel

Water Ingress – This issues only happens mainly in the boot as the rubber seals lose their seal over time, so do check under the false floor of signs of water in there. Boot seal is around £60, which can do it yourself

Panoramic Roof – They weren’t the best, to begin with, no they fail or leak – FUN Times – Replace £3k or motor £250. Use vaseline to stop water ingress as a temporary measure or WD40 silicone spray to keep the system working for the long run

Windows – They tend to have a mind of their own most of them with squeaky noises which fixed by WD40 silicone spray. The other issues is them not closing and going down before reaching the top of the window due to regulator issues or the more common issue they need resetting. A simple reset is done by holding down both window switches down for 10 seconds for full system reset

Tyres – If it’s still on run-flats do yourself a favour and buy normal tyres and get some tyre sealer – You can thank me later

Gearbox & Fuel Filter – Replace the gearbox oil and fuel filter every 50,000 miles or every 3 years – Often overlooked as we are told they are lifetime (ignore it and just do it) a fluid change is cheaper than a gearbox or new fuel pump

Diesel Engines – They are relatively cheap to run, but DPF Filters and EGR Valves will become an issue like any diesel car as the clog up with dutty diesel gunk

Manual or Auto – Get the manual – It’s a driver’s car, as the auto-box is mehhh and unresponsive a ridiculous amount to replace or fix given everything has to come out

Clubman Barn Doors – Check for signs of rust between the doors as drain points in the doors can get clogged, so water sits causing rust between the seals and door edges

Convertible Roadster & Coupe – They suffer the same issues as everything is shared on the hatchback platform. The coupe boot struts can fail quickly, given how heavy the boot lid is – you will know when you open it for the first time

Countryman & Paceman – They suffer the same issues as everything is shared on this platform minus the chassis

With everything said and done I love my JCW and the older it has got stuff will just break which you have to accept like any car but a lot of the work can be done as preventive measures. A lot of the work you can learn yourself if you want to DIY or find a good specialist or MINI dealer to help you along with your MINI Adventure. I took out the MINI Extended warranty which has saved my ass a lot of times with my turbo replacement, timing chain issues and roadside recovery to a MINI dealer for repairs with a MINI courtesy car given within a few hours – £75 a month looks cheap – link to the MINI Extended Warranty site
