If you’re in Leatherhead and your BMW or Ford has started rattling, ticking or throwing a timing-related fault code, you’ve come to the right workshop. Timing Chain Gatwick is based in Copthorne, around fourteen miles south-east of KT22 — a straightforward run down the A24 and across the M25 from Junction 9. Timing chains and Ford wet belts are the only jobs we do, so your engine has almost certainly been on our ramps before.
Sitting where the M25 meets the A24, Leatherhead has a lot of high-mileage commuter cars — Waterloo and Victoria runs from the station, weekend trips up to Box Hill, and steady London-bound traffic from Ashtead, Fetcham and the Bookhams. That kind of mileage is exactly what wears chains and wet belts out, and it’s the work we specialise in every day.
Why Leatherhead drivers choose Timing Chain Gatwick
- One job, done properly. Timing chains and Ford wet belts are all we do — the same handful of engines, day in, day out.

- Free collection within 15 miles. KT22, KT23 and KT24 all sit comfortably inside our radius.
- Fixed-price quotes in writing before any work starts — no moving numbers halfway through the week.
- 12-month parts and labour warranty on every job.
- You speak to the mechanic. Ring 01342 643 780 and you get straight through to someone who actually does the work.
Leatherhead cars and vans we work on
The mix of cars in and around Leatherhead leans heavily towards premium German metal and Ford family runabouts — which maps neatly onto the engines we handle. Typical jobs coming in from KT22, KT23 and KT24 include:
- BMW 320d, 318d, 520d (N47) — the famous rear-of-engine chain rattle. If your 3 or 5 Series sounds like a bag of bolts on a cold morning, it’s almost always the chain.
- BMW 330d, 530d, X5 30d, X3 30d (N57) — same architecture, bigger displacement, same chain at the back of the block.
- BMW 120d, 220d, 320d, X1, X3 (B47) — quieter than the N47 but still a known wearer on high-mileage cars.
- BMW 320i, 328i, 125i, X1 (N20) petrol — chain guides and tensioners are the usual story.
- BMW 340i, 440i, M140i, M240i (B58) petrol — a strong engine, but the chain is still a job we see.
- Ford Fiesta, Focus, EcoSport, Puma and B-Max 1.0 EcoBoost — the wet belt in oil is the one to watch.
- Ford Focus, Kuga, Mondeo, S-Max and Galaxy 1.5 / 2.0 EcoBlue — the diesel wet belt degrades into the oil and blocks the pickup if it’s left too long.
- Ford Transit and Transit Custom 2.0 EcoBlue — see our dedicated Transit EcoBlue belt page.
If your car isn’t listed but it’s a BMW or Ford with a chain or wet belt, ring us — chances are we cover it on the Ford side of the workshop.
Free collection from KT22
Leatherhead sits comfortably inside our free 15-mile collection zone, so there’s no need to risk driving a poorly engine over to Copthorne. We regularly collect from the town centre and the streets around the railway station, Ashtead up the A24, Fetcham, Great Bookham, Effingham, and out towards Mickleham and Box Hill.
The process is simple: fill in the free estimate form, we agree a fixed price in writing, then we collect, do the work in Copthorne and return the car. If you commute into London from Leatherhead station, we can collect while you’re at work and have it back on the drive before the weekend.
Warning signs to act on
Timing chains and wet belts very rarely let go without warning. The key is recognising the early signs and getting it looked at before the repair bill doubles or, worse, the engine writes itself off:
- Cold-start rattle from the back of a BMW diesel — loudest in the first few seconds before oil pressure builds.
- BMW fault codes 2A87, 2A82 or 2A98, often alongside rough running or a check engine light.
- Generic timing codes like P0016, P0017, P0018 or P0019 — these flag a crank-to-cam mismatch, exactly what a stretched chain or worn belt causes.
- Oil pressure warning light on a Ford EcoBoost or EcoBlue — usually wet belt debris blocking the oil pickup. Stop driving and ring us.
- Whining, whirring or ticking that changes with engine speed, particularly on the 1.0 EcoBoost.
- Black sludge or rubber flakes on the dipstick or under the oil filler cap — that’s wet belt material breaking down.
If any of that sounds familiar, please don’t keep driving it and hope it settles. Catching a worn chain or belt early is the difference between a planned, fixed-price repair and an engine that needs replacing.
Costs and what’s involved
Honest answer first: we don’t put hard figures on a web page, because the right price depends on the engine, the model year, and what’s worn alongside the chain or belt. What we will give you is a realistic, fixed quote in writing before any spanners come out.
A Ford 1.0 EcoBoost or 1.5/2.0 EcoBlue wet belt job, done properly with the oil pump and pickup checked at the same time, is the smaller of the two repairs. A BMW N47 or N57 timing chain is a much bigger undertaking — on most cars the gearbox and subframe come out to reach the chain at the back of the engine, and a genuine kit covers chains, guides, tensioners, sprockets, gaskets and seals. The B47, N20 and B58 sit in between.
Every quote is fixed in writing and we’ll walk you through exactly what’s being replaced and why. No “while we’re in there” surprises halfway through the job.
