What makes us different

The garage other garages trust

Local independent mechanics send us the engine jobs they don't have the kit or experience to do themselves. There's a reason — and it isn't the location.

No surprises. Ever.

Photos of the actual problem. A written quote. We don't pick up a spanner until you've signed it off — and if anything changes mid-job, we stop and call you first.

12-month parts warranty

On every job that isn't an engine recon, which carries a 6-month parts and labour warranty — the industry standard for full rebuilds.

What we do

We're a specialist diesel workshop. The most profitable jobs we do are also the ones we're best known for — engine work, timing chain, cylinder head, clutch, DPF and the bigger vehicles many garages can't take on.

Book Online — 24/7 Self-Service

Real-time availability, instant confirmation. Pick a date, choose the job, you're booked in — no waiting on the phone.

Booking system slow to load? Call 0121 293 9678 or message us on WhatsApp. If your car needs diagnostic work first, please call instead — the booking system is for confirmed jobs.

Diesel engine reconditioning on the workshop bench

Why local mechanics send their engine rebuilds here

A diesel engine rebuild isn't a job most general garages want. It needs a clean workspace, the right machining contacts, deep knowledge of injection systems, and the patience to do it properly — which usually means a week off your bay for one car.

We chose to specialise in it. When an engine arrives in pieces — whether it's in a 1.6 HDi nobody else will touch, a 3.0 TDI V6 with a stretched chain, a Transit Puma that's done 280,000 miles, or a Fiat Ducato out of a coachbuilt motorhome — we know what we're looking at, and we'll quote in writing with photos at every stage.

That's why other garages send their engine jobs to us. And why people who want it done once, properly, drive past closer options to bring the car here.

Cars, vans and motorhomes we specialise in

German diesel? Older Renault that nobody else will touch? Sprinter-based motorhome that won't fit on most ramps? You're in the right place.

Common questions

Diesel Automotive is not a DVSA MOT testing station. We arrange MOTs through a trusted local DVSA-licensed partner. Drop your car here, we take it for the test, and have it back to you the same day. £50 all-in.

Yes — diesel motorhome and campervan diagnostics, servicing and major mechanical repairs are a major part of what we do, subject to vehicle size, weight and booking availability. See our Motorhomes & Campervans page.

Yes — see our Van, Commercial Vehicle & Specialist Vehicle Repairs page for the full list of vehicle types and what's covered. Statutory tail lift / LOLER inspections are handled separately by certified providers.

Most cambelt jobs start from £299 fitted including water pump and tensioner. A 2.0 TDI VAG group is closer to £449. A 3.0 TDI V6 chain conversion can run higher. Send your reg and we'll quote within the working day.

Usually we can clean it. We diagnose first to confirm the DPF is the actual problem. Off-car cleaning starts from £149. Replacement is the last resort. We do not remove DPFs — that's illegal in the UK.

Typically one to three weeks depending on the engine, parts availability and machining requirements. We give you a realistic timeline with the written quote and keep you updated if anything shifts.

Yes. We're strongest on German diesels (BMW, VW group, Mercedes), Ford, Vauxhall and Renault — and we work on all major vans and motorhomes. Petrol welcome too.

Every job comes with a 12-month parts warranty. Engine reconditioning carries a 6-month parts and labour warranty — the industry standard for full rebuilds.

Yes — within a 20-mile radius of Oldbury. Fee depends on distance. Tell us where you are and we'll quote before you commit.
