Ford S-Max is not just a minivan, but a real family crossover with the dynamics of a hatchback and the spaciousness of a station wagon. Models produced from 2012 to 2023, especially in modifications from the tuning studio Remy Hobby, deserve special attention. In this article we will look at everything: from technical nuances to step-by-step instructions for repairs and upgrades.

Why exactly S-Max? This car combines comfort for 7 passengers, sporty handling (thanks to the platform Ford C1, common with Focus ST) and potential for tuning. And modifications from Remy Hobby add unique details: from sports suspensions to engine chip tuning 2.0 EcoBoost and 2.2 TDCi. But even such well-thought-out machines require competent maintenance - and this is where the questions begin.

You bought S-Max from your hands and found oil leaks? Or are you planning to install a turbocharger from Remy Hobbybut don't know where to start? This article contains answers to all technical questions, including unique connection diagrams for additional equipment for 2018+ models, which are not in standard manuals.

Technical characteristics of Ford S-Max (2012-2023) in Remy Hobby modifications

Basic versions S-Max equipped with engines from 1.5 EcoBoost (160 hp) up to 2.5T (240 hp) in top trim levels. But Remy Hobby offers much more: chip tuning, replacement of turbines, modernization of the brake system. Below is a comparison table of key parameters.

Modification Engine Power (stock/tuning) Torque Features of Remy Hobby
S-Max 1.5 EcoBoost 1.5L I4 Turbo 160 / 190 hp 240 Nm ECU firmware, sports exhaust
S-Max 2.0 EcoBoost 2.0L I4 Twin-Scroll 240 / 280 hp 340 Nm Reinforced turbine, intercooler
S-Max 2.2 TDCi 2.2L I4 Turbo Diesel 200 / 230 hp 440 Nm Upgraded injection pump, particulate filter removed
S-Max ST-Line (2020+) 2.5L I4 Turbo 240 / 300 hp 420 Nm All-wheel drive AWD, ceramic brakes

Please note: modifications Remy Hobby for diesel engines (2.2 TDCi) often involve removing the diesel particulate filter (DPF) and catalyst. It increases power, but prohibited by law in most EU countries. In Russia, such changes require re-registration with the State Traffic Safety Inspectorate.

⚠️ Attention: Removal DPF on diesels S-Max after 2018 results in an error P2463 in the ECU. This can be solved by installing Euro 2 firmware or installing an emulator.

Typical Ford S-Max faults: what breaks most often

Even with tuning from Remy Hobby, S-Max has “diseases” that are characteristic of all generations. Here are the top 5 problems owners face:

  • 🔧 Oil leak from under the valve cover (especially on engines 2.0 EcoBoost after 100 thousand km). The reason is gasket deformation due to overheating.
  • ⚡ Crankshaft position sensor failure (error P0335). Often occurs after washing the engine or in high humidity.
  • 🔥 Box overheating PowerShift (6DCT450). Requires an oil change every 60 thousand km, otherwise there will be jerks when switching.
  • 🎛️ Malfunctions of the multimedia system SYNC 3. Especially after over-the-air (OTA) updates.
  • 🚗 Creaks in the front suspension (stabilizer struts and control arm silent blocks wear out by 80 thousand km).

If your S-Max underwent tuning in Remy Hobby, add to this list:

  • 🔥 Intercooler problems (on models with forced 2.0 EcoBoost). Requires additional airflow.
  • ⚡ Knock sensor errors (code P0328) after chip tuning. Solved by updating the firmware.

The most insidious malfunction - antifreeze leaking into the cabin through the stove. It appears as dampness under the front passenger carpet. The reason is cracks in the heater core. On models before 2017, the radiator is plastic, after - aluminum (more reliable).

DIY Ford S-Max repair: step-by-step instructions

Not all work requires contacting the service. For example, engine oil change or cleaning the throttle valve you can do it yourself. Below are instructions for the most common procedures.

1. Changing the engine oil 2.0 EcoBoost

Frequency: every 10 thousand km (or 15 thousand km for oils 5W-30 with permission Ford WSS-M2C913-D).

Oil 5W-30 (5.4 l)|Oil filter (part number: 5015405046)|Drain plug wrench (15 mm)|Funnel and waste container|New drain plug gasket (part number: 1776431)

-->

Step by step instructions:

  1. Warm up the engine to operating temperature (60-70°C).
  2. Raise the car on a lift or use a jack (the jacking point is under the front side member).
  3. Remove the crankcase protection (4 x 10 mm bolts).
  4. Unscrew the drain plug (15 mm wrench) and drain the oil into a container.
  5. Replace the oil filter (located to the right of the engine, unscrews counterclockwise).
  6. Screw on the plug with a new gasket, fill in oil through the neck (volume - 5.4 l).
  7. Start the engine, let it run for 2-3 minutes, check the level with a dipstick.
⚠️ Attention: On engines 2.0 EcoBoost After 2019, the oil filter has a built-in check valve. When replacing the filter it's impossible use analogues without a valve - this will lead to oil starvation at startup!

2. Cleaning the throttle valve

Symptoms of contamination: floating speed, jerking during acceleration, error P2106 (Throttle ECU).

Tools: carburetor cleaner (Liqui Moly Pro-Line), soft bristle brush, rags.

Procedure:

  1. Remove the air duct (disconnect the clamps from the air filter box and throttle body).
  2. Disconnect the throttle position sensor connector.
  3. Clean the valve and channels with cleaner (do not use metal brushes!).
  4. Wipe the throttle position sensor with alcohol.
  5. Reassemble everything in reverse order, perform throttle adaptation using a diagnostic scanner (for example, Launch X431).
💡

If after cleaning the speed continues to fluctuate, check the absolute pressure sensor circuit (MAP-sensor). On S-Max it often becomes clogged with oil dust from the crankcase ventilation system.

Ford S-Max tuning: what Remy Hobby offers

Remy Hobby specializes in comprehensive tuning S-Max, including:

  • 🚀 ECU chip tuning (15-40% increase in power depending on the engine).
  • 🔧 Installation of sports turbochargers (for example, Garrett GT2860 for 2.0 EcoBoost).
  • 🎨 External tuning: body kits, spoilers, headlight tinting.
  • 🔊 Audio preparation: Installation of subwoofers and amplifiers under the seats.
  • 🛡️ Strengthening the brake system (discs Brembo, pads Ferodo DS2500).

Most popular package - "Stage 2" for 2.0 EcoBoost:

  • ECU firmware for 98 gasoline.
  • Installing an oversized intercooler.
  • Replacing the exhaust system with a silent one (Remy Hobby Exhaust).
  • Increased grip (Sachs Performance).

The cost of such an upgrade is from 180 to 250 thousand rubles (depending on the configuration). But it is important to remember: after tuning necessarily you need:

  1. Update the transmission firmware (for PowerShift - a separate procedure).
  2. Install an additional oil cooler (for power over 280 hp).
  3. Check the life of the turbine - after a mileage of over 150 thousand km, it is better to replace it in advance.
What happens if you don’t upgrade your brakes after chip tuning?

When increasing power to 300+ hp. standard brake discs (292 mm) overheat after 3-4 intense braking. This leads to disc deformation (“beating” of the steering wheel) and an increase in braking distance by 30-40%. Solution - install disks 330 mm from Ford Focus RS or Brembo with 4-piston calipers.

SYNC 3 firmware update: instructions and nuances

Multimedia system SYNC 3 on S-Max After 2016, it supports over-the-air (OTA) updates, but often these updates lead to crashes. Let's look at how to update the system manually.

What you will need:

  • Flash drive FAT32 up to 32 GB.
  • Firmware files from the official website Ford (choose the version for your region!).
  • The battery must be charged at least 50%.

Step by step instructions:

  1. Download the archive with the firmware and unzip it to a USB flash drive (the files should be in the root, without folders!).
  2. Insert the flash drive into the USB port SYNC 3 (it's better to use the front port under the armrest).
  3. Go to menu Settings → General → Software Update.
  4. Select "Install from USB" and confirm the process will begin.
  5. Wait for completion (about 20-30 minutes). Don't turn off the ignition!
  6. After rebooting the system, check the software version in the menu Settings → About the system.
⚠️ Attention: If after the update SYNC 3 stopped seeing the phone via Bluetooth, reset the system settings to factory settings (Settings → General → Reset). This will solve the problem in 90% of cases.

For models S-Max with tuning from Remy Hobby Alternative firmwares with advanced functions are available:

  • Support Android Auto and Apple CarPlay for older versions SYNC 2.
  • Activating the tire pressure display (TPMS) on the screen.
  • Removing the speed limit for the video player (relevant for families with children).
💡

Updating SYNC 3 via USB is more reliable than over-the-air (OTA). After manual flashing, the system works more stable, and the risk of freezing is reduced by 70%.

Suspension and steering: diagnostics and repair

Suspension S-Max built on the basis Ford Focus, but with reinforced elements due to greater weight. However, the resource of parts leaves much to be desired:

  • 🔧 Stabilizer links — enough for 60-80 thousand km (article: 1715742).
  • 🔥 Support bearings — they start knocking after 100 thousand km (article: 1754950).
  • 🚗 Rear arm silent blocks — crack at 120 thousand km (article: 1848960).
  • 🎛️ Steering rack — leaks after 150 thousand km (repair is possible, but it is better to replace it with a new one).

For tuned versions from Remy Hobby recommended installation:

  • 🔧 Sports shock absorbers (KW V3 or Bilstein B14).
  • 🚗 Reinforced stabilizers (Whiteline).
  • 🛡️ Polyurethane silent blocks (Powerflex).

How to diagnose suspension problems:

  1. Knock when driving over bumps - Check the stabilizer struts and support bearings.
  2. Pulling the car to the side — measure the wheel alignment (standard: -0.5° ± 0.3° for the front axle).
  3. Vibration on the steering wheel — wheel balancing or wear of CV joints.

To replace the stabilizer struts you will need:

  • 15 mm and 17 mm wrench.
  • Puller for ball joints.
  • WD-40 (bolts often stick).
💡

When replacing rear arm silent blocks, use hydraulic press. Attempt to press them in with a hammer will damage the rubber!

Electronics and diagnostics: how to read errors without a scanner

On S-Max after 2015, Engine Control Unit (ECU) errors can be read without diagnostic equipment - using secret menu.

How to enter the engineering menu:

  1. Turn on the ignition (do not start the engine).
  2. Press and hold the button OK on the steering control.
  3. Without letting go OK, press the brake pedal 3 times.
  4. Release the button OK — the diagnostic menu will appear on the on-board computer screen.

Available in this menu:

  • Error codes (DTC).
  • Real-time sensor parameters (temperature, pressure, throttle position).
  • Test of actuators (fans, valves).

Decoding popular errors:

Error code Description Possible reason Solution
P0171 Lean air-fuel mixture Air suction, faulty MAF sensor Check the tightness of the air ducts, clean the sensor
P0300 Multiple cylinder misfire Misfires, faulty spark plugs or coils Replace spark plugs (NGK 97506), check the coils
P2187 Lean mixture at idle The throttle is dirty or PCV valve Cleaning the throttle, replacing the crankcase ventilation valve
U0100 Lost communication with ECM Wiring or ECU problems Check the fuse F30 (10A) in the block under the hood
⚠️ Attention: If after resetting the errors they appear again, do not ignore the problem! For example, code P0420 (low catalyst efficiency) on models with remote DPF may indicate incorrect ECU firmware.

FAQ: Frequently asked questions about Ford S-Max and Remy Hobby

Is it possible to install gas equipment on an S-Max with a 2.0 EcoBoost engine?

Technically yes, but not recommended. Engines EcoBoost They have a high compression ratio (9.3:1) and direct fuel injection, which makes them sensitive to detonation on gas. If you still decide, choose equipment BRC Sequent or Lovato with adjustment of the ignition timing.

What is the service life of the PowerShift box on the S-Max?

With proper maintenance (oil change every 60 thousand km) the gearbox 6DCT450 runs 200-250 thousand km. Main enemies: overheating and aggressive driving. For tuned versions (Remy Hobby) it is recommended to install an additional oil cooling radiator.

Which tires are best for an S-Max with suspension tuning?

For sports suspension (KW or Bilstein) optimal choice:

  • Summer: Michelin Pilot Sport 4 (size 235/40 R19).
  • Winter: Continental WinterContact TS 860 (size 225/45 R18).

Avoid low profile tires (35 and below) - this reduces comfort and increases the load on the suspension.

What to do if the Check Engine light comes on after chip tuning?

First check the error code through the engineering menu (see section above). Most often this is:

  • P0300 - misfires (you need to replace the spark plugs with NGK 97506 or Denso Iridium).
  • P0299 — low boost pressure (check the intercooler and pipes for air leaks).

If the error does not clear, contact Remy Hobby to update the firmware.

How to disable start-stop on S-Max?

There are two ways:

  1. Temporary shutdown: press the button A/O on the panel (resets after restarting the engine).
  2. Permanent shutdown: disconnect the neutral sensor connector (located on the gearbox) or reflash the ECU (the service costs ~5 thousand rubles).

On models after 2020, disabling start-stop via the diagnostic scanner (Launch X431) takes 5 minutes.
