Major Service for Croydon drivers

Reaching 24,000 miles in a year, not two

Between Wellesley Road, the Park Lane underpass, the Fiveways junction and the queues through Addiscombe, Croydon mileage comes in small, hard pieces. For private-hire and delivery drivers working out of the centre near East Croydon station and Boxpark, 24,000 miles can be a single year's work. The major service is a two-year job for most cars and an annual one for those, and the reason is in the parts rather than the label.

Spark plugs are the clearest case. As the electrode wears, the coil has to generate a higher voltage to jump the gap, and on a hot engine under load it eventually fails to. What follows is a misfire, and a misfire pushes unburnt fuel into the catalytic converter, which overheats and breaks down internally. A catalytic converter costs several times what a set of plugs does, so leaving plugs late is a false economy that shows up as a flashing engine light.

We fit plugs to the exact type, heat range and gap your engine is specified for, from makers such as NGK, Denso or Bosch, torqued to specification rather than tightened by feel, and we do not substitute something similar-looking that claims to be an upgrade. On diesels the fuel filter takes the plugs' place, protecting the high-pressure pump from water and debris. The brake fluid is changed completely and moisture tested before and after.

Everything in the full service comes with it, including the wheels off with pad and disc measurements recorded, which on this kind of mileage is the figure worth watching. Allow most of the day, because plugs under an inlet manifold and the fluid change both take real time. We quote in writing first, and collection and delivery can be arranged for drivers who cannot afford the trip across. We will tell you what came out as well as what went in.

Servicing

Major Service: what’s involved

Some parts do their job quietly for years and then start costing money. Spark plug electrodes erode a fraction with every firing, and as the gap widens the ignition coil has to work harder to jump it, which is how a worn plug ends up taking a coil with it. A diesel fuel filter collects water and debris until flow through it falls away, starving a high-pressure pump built to very fine tolerances.

Brake fluid is hygroscopic: it draws moisture out of the air through the reservoir and the flexible hoses, and a few per cent of water is enough to pull its boiling point down towards where hard braking takes it. None of these three gives much warning before it becomes a problem. A major service renews them on schedule rather than after they fail, and it is the natural point to take stock of what is coming next.

Signs your car is due a major service

Two years or 24,000 miles since the last one

The longer-interval items run to time as well as distance, so the date matters even on a car that has not covered the mileage.

Hesitation or a stumble under load

Worn plugs struggle most when cylinder pressure is highest, so the misfire shows up pulling uphill or accelerating hard rather than at idle.

Engine management light flashing

A flashing light means a misfire serious enough to risk damaging the catalytic converter with unburnt fuel. Ease off and get it looked at rather than carrying on.

Longer cranking on a cold morning

A petrol engine that takes an extra second or two to fire when cold is often running plugs with a gap that has widened past its best.

A diesel that runs out of puff at speed

Power that falls away after a sustained motorway run, or under load with the car fully laden, can be a fuel filter restricting flow just when demand is highest.

Water in fuel warning on a diesel

Many diesel filters include a water trap with a sensor. The warning means the trap needs draining and the filter is usually at or past the end of its service life.

Brake pedal softens on a long descent

Fluid that has absorbed moisture boils at a lower temperature, and the vapour compresses where fluid would not. A pedal that goes long after repeated heavy braking points at fluid rather than pads.

No record of plugs or fluid ever being changed

On a car bought used with a patchy history, assume the long-interval items are overdue until the paperwork shows otherwise.

When should it be done?

For most cars a major service falls every 24 months or 24,000 miles, but the parts inside it run to their own intervals and they do not all come due together. Spark plug life depends on the type fitted: nickel plugs are often specified every 20,000 to 30,000 miles, while platinum and iridium plugs can run 40,000 to 60,000 miles or more. Diesel fuel filters are commonly every 2 years or 20,000 to 40,000 miles. Brake fluid is a strict two-year item on most cars whatever the mileage.

Typically every 24 months or 24,000 miles, or at your manufacturer's longer interval
Spark plugs: around 20,000 to 30,000 miles for nickel, 40,000 to 60,000 miles or more for platinum and iridium
Diesel fuel filter: commonly every 2 years or 20,000 to 40,000 miles where the filter is serviceable
Brake fluid: every 2 years on most cars, counted by time rather than mileage
Low-mileage cars: the time-based items still fall due even when the mileage items do not

How we carry out a major service

Work out what is actually dueBefore quoting we check your engine's schedule and the service record to see which long-interval items genuinely fall now. If your plugs were done 8,000 miles ago we say so and leave them alone.
Oil, oil filter and the annual filtersEngine oil and filter are renewed with Castrol to your manufacturer's approval, and the air and cabin filters are replaced as they would be at a full service.
Spark plugs on petrol enginesCoil packs come off and each plug well is checked for oil from failed tube seals before the new plugs go in. They are tightened with a torque wrench to the manufacturer's figure, because over-tightening damages an aluminium head and under-tightening stops heat escaping through the seat.
Fuel filter on dieselsWhere the car has a serviceable external filter we renew it with the seals from the kit, drain the water trap and prime the system so the car starts without long cranking. Some cars use an in-tank filter that is not a service item, and we will tell you if yours is one of them.
Brake fluid changeFresh fluid from a sealed container is pushed through with a pressure bleeder in the sequence the manufacturer specifies, and on cars that require it the ABS pump is cycled with diagnostic equipment so old fluid is not left in the unit.
Wheels off and full inspectionPad and disc thickness are measured and recorded, and suspension joints, bushes, gaiters, hoses, pipes and the exhaust are checked with the car raised and the wheels off.
Battery, charging and diagnosticsThe battery is tested for condition, the charging output measured, and the control modules scanned for stored and pending fault codes.
Reset and recordThe service indicator is reset, the book stamped or the digital record updated as a major service, and the items now due next are noted, including the cambelt interval where your engine has one.
Road test and handoverThe car is road tested with particular attention to pedal feel after the fluid change and to how the engine pulls after new plugs, then we go through the report and the measurements with you.

Parts and fluids we fit

Spark plugs are fitted to the exact type, heat range and gap your engine is specified for, from makers such as NGK, Denso or Bosch, and we do not substitute a plug because it looks similar or claims to be an upgrade. Fuel filters are OE or OE-equivalent from suppliers such as MANN, Bosch or Delphi, with the seals supplied in the kit. Brake fluid comes from a sealed container in the grade the car calls for, usually DOT 4 or DOT 4 low viscosity.

Castrol engine oil to your manufacturer's approval, with a new oil filter
Air filter and cabin filter of the correct type for the car
Spark plugs to the specified type, heat range and gap, from NGK, Denso or Bosch
Diesel fuel filter from suppliers such as MANN, Bosch or Delphi, with new seals
Brake fluid from a sealed container, usually DOT 4 or DOT 4 low viscosity
New sump plug washer and any single-use fixings the job calls for

How long it takes

3–4.5 hours

Allow most of a day with us. A four-cylinder petrol with accessible coil packs is quick; engines with more cylinders, plugs sitting under an inlet manifold, or a fuel filter mounted awkwardly under the car take considerably longer, and the brake fluid change adds around 45 minutes on top, more where the ABS pump has to be cycled. We will call you as soon as the car is finished.

Spark plugs where your petrol engine is due them, torqued to specification
Fuel filter where your diesel has a serviceable one, with the system primed afterwards
Complete brake fluid change, with moisture content tested before and after
Diagnostic scan, service indicator reset and service record updated
Written report, road test and a 3-month workmanship warranty on any repair work

Getting here from Croydon

From Croydon to our Hackbridge workshop

From the town centre take the Croydon Flyover (A232) west onto Duppas Hill Road and Epsom Road to the Fiveways junction with Purley Way (A23). Continue on Croydon Road (A232) through Waddon and Beddington, past Beddington Park, to the junction with Manor Road and London Road in Wallington, then turn right onto London Road (A237) and head north to Hackbridge; Soho Mills is on the right.

A232 flyover west onto Duppas Hill Road to Fiveways, then Croydon Road through Waddon and Beddington to Wallington and right up London Road, roughly fifteen minutes. Collection from Croydon can be arranged if the car is working for you.

About Croydon

Croydon is one of the largest commercial centres in Greater London: a dense town centre of office towers, flats and shopping around East and West Croydon stations, ringed by Victorian and Edwardian terraces and leafier inter-war suburbs such as Addiscombe, Shirley and South Croydon. It is a busy place with a large commuting population thanks to fast trains to London Bridge and Victoria. Driving through the centre means multi-lane gyratories, the Croydon Flyover and Underpass, tram tracks and heavy traffic on the A23 and A232 corridors, while the side streets are mostly 20mph and tightly parked.

Questions

Major Service in Croydon: your questions answered

At 24,000 miles a year, do I need a major service annually?

Something close to it, though we would rather work out what is genuinely due than apply the label. Plugs and the fuel filter come round on mileage, so yes at your rate. Brake fluid is a two-year item by time, so it will not be due every year. The quote reflects what the car actually needs.

Can plugs cause a loss of power under load rather than a rough idle?

Very commonly, yes. At idle there is little cylinder pressure, so a tired plug still fires, but under boost or hard acceleration the spark struggles to jump the gap. Hesitation on a motorway slip road or pulling away uphill with a smooth idle is a classic worn-plug symptom on a turbo petrol engine.

Will you need the car all day?

Most of it. Three to four and a half hours is typical, depending on how accessible the plugs are and whether the ABS pump needs cycling for the fluid change. Drop it early and we will ring you as soon as it is finished rather than leaving you waiting for the end of the day.

Does a major service include the cambelt?

No, and any garage implying it does is worth questioning. Cambelt intervals are set by engine, commonly somewhere between 60,000 and 100,000 miles or five to ten years, and the job involves removing covers, mounts and ancillaries. We tell you when yours falls due and quote it separately.

My car is a diesel. What do I get instead of spark plugs?

A diesel has no spark plugs, so the equivalent long-interval item is the fuel filter where the car has a serviceable one. Glow plugs are not a service item: they are replaced when one fails or when a diagnostic scan shows a circuit fault, and that is a separate repair.

I do very low mileage. Do I need a major or will a full do?

The time-based part of the major still applies. Brake fluid is a two-year item whether the car moves or not, and oil and filters age by date. The mileage items, particularly spark plugs, may well not be due, and we will not charge you for plugs you do not need.

Does it include coolant, gearbox oil or an air conditioning service?

No. Coolant, gearbox and differential oils and air conditioning all run to their own intervals, which vary widely between makes. We check the record and flag anything that has fallen due, then quote it separately so you can decide what to do and when.

Will a major service clear my engine management light?

Only if the cause happens to be something the service renews, such as a misfire code from worn plugs. A light with any other cause needs proper diagnosis, and clearing a code without fixing the fault simply hides it until the light returns. We tell you which situation you are in before we start.
