VW Sharan Common Problems: An Owner's and Buyer's Guide

The second-generation Sharan, launched in 2010, facelifted in 2015 and built until 2022, is one of the more sensible seven-seaters you can own: sliding rear doors, three proper individual middle-row seats, and a body that copes with family life. Its problems tend to be predictable rather than dramatic. The headline items are the sliding door mechanisms and their wiring, the diesel EGR and DPF hardware, the timing chain on the earlier 1.4 TSI petrol, DSG gearbox servicing, and blocked drains letting water into the cabin. None of that should put you off the car; it simply tells you where to spend your inspection time.

Engines and timing: chain or belt depends on the engine code, not the year

Before you budget for anything, find the engine code. It is three or four letters, usually recorded in the service book and on the vehicle data sticker, and it is what decides whether you are looking at a timing chain or a timing belt. Two Sharans of the same age can differ here, and getting it wrong is the sort of mistake that ends in a rebuild.

The 1.4 TSI in pre-facelift cars is the older EA111 engine, carrying codes such as CAVA, CTHA and CNWB. Every one of them is twincharged: a belt-driven Roots-type supercharger fills in at low revs alongside the turbocharger. Do not let that belt confuse you, because it drives only the supercharger. The camshafts run on a roller timing chain, and that chain and its tensioner are the known weak point. The warning is a rattle for a second or two on a cold start, and if a worn chain jumps a tooth you get a non-runner and, on an interference engine, bent valves. A revised tensioner has long been available, so ask whether it has been fitted and get evidence. The supercharger clutch and its drive belt are separate items worth checking on the same engine.

Later Sharans use the EA211 1.4 TSI, with codes such as CZDA and DJKA, and that engine changed the camshaft drive to a toothed belt. The changeover arrived with the 2015 facelift, but check the code rather than dating it by the registration. The interval is long, but it is a hard deadline: this is an interference engine and a belt that lets go takes the valvetrain with it.

The 2.0 TSI, where it was offered, is chain-driven in both the earlier 200 PS form and the later 220 PS one. On the earlier version watch for oil consumption and ask the owner how often they top up, and listen for a whistle or a lumpy idle from a failed crankcase breather diaphragm.

All Mk2 Sharan diesels are common-rail 2.0 TDIs, in outputs from around 115 to 184 PS. They are not PD engines, so the old pump-injector and camshaft wear stories from previous-generation VWs do not apply here. They run a timing belt, they are interference engines, and the water pump is normally driven by that same belt and replaced with it. Evidence that the belt job was actually done matters far more than the number on the odometer, because a snapped belt on one of these is an engine, not a repair.

• Cold-start rattle on a chain-driven petrol: investigate before buying, not after
• Diesel: look for a belt and water pump invoice, with the engine code on it
• Check oil level and colour on any TSI, and ask about top-up frequency

The diesel emissions system: EGR, DPF and AdBlue

Plenty of Sharans are diesels doing short local journeys, and that is the hardest life a diesel particulate filter can have. A filter that never gets a clean regeneration slowly loads up, the car starts running regens more often, and diesel washes past the rings into the sump. Oil sitting above the maximum mark on the dipstick is a genuine warning sign, not an overfill.

The EGR valve and cooler clog with soot and can leak coolant internally, giving rough running, warning lights and limp mode. On the earlier EA189 common-rail cars, the plastic intake manifold's swirl flap actuator and its lever are a well-known failure, typically showing as a stored intake flap fault and a car that feels flat; the later facelift diesels use a revised manifold and suffer far less with it. Turbo vanes sticking with soot are another classic: a sudden loss of boost that often clears after a restart.

The facelift diesels are the Euro 6 AdBlue cars, sold as TDI SCR, and their SCR system brings NOx sensors and a dosing system that are not cheap when they fail. On the earlier cars, the EA189 engine is the one covered by the emissions service action; a VIN check with VW will tell you whether a particular car was affected and whether the work was done, and it is worth asking how it drove afterwards. That is part of the history rather than a reason to walk away, but combined with heavy short-trip use it is worth weighing up.

Gearboxes and clutches

The automatic in this car is a DSG dual-clutch, not a torque converter and not a CVT, and it behaves differently as a result. Slight creep-speed hesitation is normal; shuddering, jolting between the lower gears, flaring between shifts, a flashing gear display or a drop to a couple of gears only is not.

One useful simplification: every version of this Sharan, petrol or diesel, before or after the facelift, was sold with either a six-speed manual or the six-speed wet-clutch DSG. There is no dry-clutch seven-speed unit in this model, so you do not have to work out which type you are looking at. What you do have to check is that the DSG has had its scheduled oil and filter change. Skipping it is the single most common route to trouble, so an invoice for it is a genuine green flag, and a car with no record of it should be priced accordingly.

Manual cars are simple but heavy on the clutch. A dual-mass flywheel rattle at idle in neutral that goes quiet when you press the clutch pedal is the usual sign of wear, and it is a gearbox-out job when it is done. Four-wheel drive was a diesel option on this car, and the 4MOTION coupling has its own oil service that is regularly forgotten.

Sliding doors, tailgate and water ingress

The sliding rear doors are the Sharan's best feature and its most common repair. On electric doors the wear points are the drive motor and cables, the guide rollers and lower arm, door adjustment (a door slightly out of line hits the catch and bounces back open), the anti-trap sensing, and the flexible wiring conduit at the door that has to bend every time the door moves. A snapped wire in that loom is the usual explanation when the window, central locking, speaker and door module on one side all misbehave together. Manual doors are far simpler, but should still slide with one hand and latch cleanly when parked on a slope.

The powered tailgate, where fitted, wears its struts and drive, and the loom crossing from the roof into the tailgate can chafe and cause rear wiper, high-level brake light or release button faults.

Water gets in through blocked drains rather than through the panels. Check the scuttle drains under the windscreen, the roof drains if it has a glass panoramic roof, and lift the boot floor and the third-row carpet. Damp carpets are the underlying cause of a surprising number of "random" electrical faults, because control modules and connectors live low down in the car. Find the leak first; replacing drowned parts without clearing the drain just buys the fault again.

Suspension, brakes and steering

This is a heavy car, often carrying seven people, and the front suspension wears accordingly. Front lower arm bushes give a knock over bumps, vague straight-line steering and uneven inner-edge tyre wear. Anti-roll bar drop links rattle over broken surfaces at low speed. Strut top mount bearings creak or clonk on full lock at parking speeds. A wheel bearing announces itself as a drone that changes as you sweep the steering left and right at a moderate cruising speed on a quiet road.

Rear brakes suffer from the combination of weight and short journeys: corroded discs and seized caliper guide pins are common, and they show up as noise, uneven pad wear and MOT advisories. In salted-road areas a broken rear coil spring is worth ruling out if you hear a metallic clonk over bumps.

Warning lights on the safety systems deserve proper diagnosis rather than clearing. An ABS or ESP light means the car may not behave as you expect under emergency braking; wheel speed sensors and corroded connectors are frequent culprits, and after alignment or suspension work the steering angle sensor needs its basic setting performed or the lights will stay on. An airbag light means the restraint system has logged a fault and may not deploy as intended in a crash, so treat it as a job for a scan tool that can read the airbag module, not something to reset and forget.

Inside, climate and electrics

Work every seat. The third-row seats fold into the floor and their latches must lock positively, with the indicators showing correctly, because a seat that is not locked is a safety issue rather than an inconvenience. The middle-row rails can get stiff or jam, particularly on cars that have carried child seats for years.

Three-zone climate systems can lose the rear blower, and a musty smell usually means the evaporator drain is blocked rather than a dead air conditioning system. Air conditioning that has gone gradually weak is often a slow leak from a stone-damaged or corroded condenser sitting at the front of the car.

On stop-start cars, a replacement battery that was never registered to the energy management system leads to persistent undercharging and a scattering of unrelated warning lights. If a seller mentions that electrical problems were cured with a new battery, ask whether it was coded in. Elsewhere, look for headlight condensation, xenon levelling faults, screen delamination or slow boot-up on older infotainment units, and a reversing camera that has taken in moisture.

Test drive and pre-purchase checks

Arrange to see the car completely cold. Most of the useful information on a Sharan appears in the moments around a cold start and in a slow walk around the car before you set off.

Then drive it properly: parking-speed manoeuvres, a full-throttle pull in a high gear, and enough of a steady run to let a diesel complete a regeneration if it wants to.

• Cold start: listen for chain rattle on the earlier petrols, and check for smoke that does not clear
• Dipstick: oil above maximum on a diesel points to fuel dilution and unfinished regens
• Cycle both sliding doors several times over, from the key, the inside switch, the outside handle and the driver's console, then repeat on a slope
• Fold every rear seat down and back up, and confirm each one latches
• Press the front footwell carpets and the boot floor with your palm, lift the boot floor, and use your nose
• Feel for DSG judder at walking pace and for any jolt between the lower gears
• Speed bumps and a rough road for knocks; a flat road, briefly hands-light, for pull
• Paperwork: cambelt or chain evidence matched to the engine code, DSG oil service, and any outstanding recalls checked against the VIN

Fault codes that commonly turn up on a Sharan

A stored code names a circuit and a symptom, not a broken part. Read it as a starting point for testing rather than a shopping list. These are the ones that appear most often on this model.

One caveat specific to this car: the faults that matter most on a Sharan often are not engine faults at all. Sliding door, comfort, airbag and ABS modules keep their own memories, and a basic OBD-II reader only talks to the engine and emissions side by design, so it will show a clean bill of health on a car with a boot-full of body faults. A tool that scans every module is what you want here. VAGPULSE, the Windows software and cable we build, does that across VW, Audi, Skoda and SEAT, along with live measuring blocks, coding and adaptations, which is how you tell whether a door fault is the motor, a switch or a broken wire in the hinge loom, and whether someone cleared a screenful of codes the week before the viewing.

• P2015 - intake manifold flap position on the earlier 2.0 TDI: the actuator and lever, usually a manifold replacement
• P0401 / P0402 - EGR flow too low or too high: a clogged valve or cooler, sometimes a leaking cooler
• P2002 / P242F - DPF efficiency or restriction: soot or ash loading, typically from short-journey use
• P0299 - underboost: sticking turbo vanes, a split boost hose or a leaking intercooler pipe
• P0087 - fuel rail pressure too low: filter, low-pressure supply or high-pressure pump. Do not keep driving on it
• P20EE - SCR catalyst efficiency on the Euro 6 AdBlue diesels: NOx sensor or the dosing system
• P0016 / P0011 - crank and cam correlation or cam timing on the petrols: take this seriously on the chain-driven engine
• P0171 - system too lean on a petrol: crankcase breather diaphragm or an intake leak
