F00VC01333 Common Rail Injector Control Valve for Bosch CRI2.1

Start with the part in your hand. A Bosch cap of this family carries its code on the body, and that code is what an order has to match. If the characters read F00VC01333, you are on the right page. If they read anything else, stop — tell us the code you can actually see and we will quote against that, because a valve taken from one injector is sometimes fitted into another, and the code on the bench is the one that counts.

Rebuilders usually arrive from the injector side instead, and the same rule holds. Reading an injector control valve part number means reading it off the valve itself. This matters because the two numbers on a unit are different things: what may look like an injector valve part number stamped into the body is the injector number, while a Bosch control valve part number of this family is marked on the valve cap. If the cap face is unreadable, the code cannot be recovered from the body alone, and no chart will supply it. That is why how to identify an injector control valve comes down to the code you can physically read.

Fitment check, honestly stated. We could fill this section with an application list copied from a marketplace listing. We do not, because no independent catalogue we have checked publishes a vehicle application for this valve code, and a guess printed confidently is still a guess. What we do instead is a F00VC01333 fitment check against your own injector, confirmed in writing. That is one message slower and considerably safer than a return.

One point worth repeating for anyone also browsing a control valve cross reference guide: a cap of this type is matched to the injector it is built into, because the cap carries a calibrated face. A valve from any other common rail family is not a substitute and does not become one because the two parts are a similar size. Match by code, and when the code is unclear, ask before you buy.

A modern common rail injector is opened electronically rather than by a mechanical linkage, and the part that does the opening is the solenoid control valve. Because it governs the return path rather than the spray, a common rail control valve decides both the timing and the quantity of each injection event. The F00VC01333 is that valve: a matched cap and stem that sit at the top of the injector, above the nozzle, and release high-pressure fuel back to the return line at the moment the solenoid is energised.

The sequence is short, but the consequences are not. When the solenoid lifts the valve, pressure above the needle falls and the needle opens; when the solenoid releases, the valve closes again and the injector re-arms. Because the valve controls the orifice in the control valve return orifice path, it behaves as a metering part rather than an on-off tap. The bore in the cap, the matching face on the stem and the sealing ball together set how much fuel goes back to the tank on every cycle.

That is also why the cap carries an etched calibration face. A valve is matched to the injector it will run in so the return quantity stays inside tolerance, and two valves can look identical while being calibrated differently. A rebuild that ignores this is the most common reason an injector runs badly after a valve swap. In this family the characters cut into the cap are batch, date and flow codes rather than a part number, which is why the code you can read on the old valve is the one that has to be matched.

On this valve code the cross-reference trail is short but useful. Supplier and reseller data listing the parent injectors names two CRI2.1 units, 0445110218 and 0445110286. That gives a buyer something to check against rather than nothing at all, and a control valve parent injector reference of this kind is worth having before a rebuild bench commits to a batch. It is still a lead rather than a promise: the same source set lists no vehicle for the code, so the honest position is a reference you verify against your own injector number, not a chart we publish.

In service a valve wears in a few predictable ways. Diesel is not perfectly clean, so fine debris laps the stem and the cap bore over time. Heat and pressure cycling can leave the ball and its seat slightly grooved or varnished. A valve that no longer seals cleanly returns too much fuel, rail pressure takes longer to build, and the injector delivers less fuel than the ECU expects. The correction map absorbs the difference for a while; once the correction runs out, the cylinder starts to misfire, knock or smoke.

We supply the F00VC01333 valve set as a control valve cap and stem pair, matched before it is packed. It is a Vidishi Auto compatible replacement built to the Bosch specification for this valve family and sold under our own brand; it is not a Bosch-branded product and we do not describe it as one. It belongs with the other common rail injector parts a bench consumes, alongside the injector spare parts and the wider diesel fuel injector parts that sit on the same bench.

What does an injector control valve do? In one line: it opens and closes the return path so the pressure above the needle can rise and fall. Because a common rail injection system holds the whole rail at pressure, a diesel injector valve that no longer seals changes the pressure the injector actually sees. A fuel injector valve fault is therefore read on a bench rather than from a scan tool, and fuel injector control valves are handled as matched, calibrated parts, never as loose stock that can be swapped between injectors. A diesel injector control valve is also one of the first parts replaced at rebuild, because it is the cheaper half of the injector’s upper assembly and the half that sets return flow. Stocking bosch common rail injector parts for a bench usually starts here, with common rail valve parts that can be confirmed by code, and a control valve replacement is fitted as a complete set rather than built up from loose pieces.

How we label data. Reference values come from reseller and technical cross-reference data and say which family and which parent injector this valve belongs to, rather than claiming OE origin. Not published means the field is left blank on purpose. A valve’s return behaviour and its sealing performance are verified on an injector test bench against one specific injector, so a number we cannot stand behind would be worse than no number at all.

What is in the box. The injector control valve assembly ships as one matched set: the valve cap and the valve stem that were lapped and paired together. Those injector control valve components are not sold separately, because a cap calibrated for one injector will not hold tolerance in another, and mixing halves from two batches is how a rebuild loses its return figure. For a bench the practical stocking unit is an injector control valve kit per injector rather than loose pieces. The stem and the cap bore are finished as a pair and kept together from that point on, and the control valve sealing ball that closes the return path travels with the same pairing. The control valve seat face is the surface that decides whether the valve seals, so bore condition matters as much as the valve itself. Where a specific figure such as the injector control valve dimensions is needed for an injector, we confirm it against your injector number rather than publishing a generic value here.

Read this as a F00VC01333 equivalent table and it will disappoint you, because it is deliberately short and it is not an interchange list. It shows the two ways the same number is written, the family prefix, and a neighbouring code that is not the same part. Buyers regularly reach a valve page from an injector search, so it is worth being blunt: we have not found a published vehicle application for this code and we are not going to invent one to fill a row.

The one lead we can hand over is a cross reference trail that runs from this valve to the parent injectors. Data listing 0445110218 and 0445110286 as the host injectors is consistent across several reseller and technical sources, which is enough to present as a Reference and not enough to print as a fitment. Use it to sanity-check the injector in front of you, then send us the number to confirm the pairing.

Two search lines are worth answering directly. Anyone looking for a Bosch-numbered bosch F 00V C01 333 is looking at this same valve written with Bosch spacing; a bosch injector valve from a different family is not an alternative, and neither is a neighbouring code in this one. If your cap belongs to the F00VC01 valve family we can narrow it down quickly, but the last step is always the same, which is how to match a control valve to an injector by checking the number on both.

A valve set is only as good as its sealing faces. The bore is checked for burrs, and the cap face carries the batch, date and flow characters used on the bench. That is why the assembly is replaced as a unit rather than by swapping a single piece.

• Rough idle and a misfire on one cylinderWhen the valve returns too much fuel the affected cylinder gets less than the ECU expects. An intermittent misfire at idle is usually the first thing a driver reports.
• Hard starting and a long crankRail pressure takes longer to build if the valve does not seal, so the engine cranks for longer before it fires.
• Fuel knock or a sharp rattleAn over-returning valve shifts injection timing and quantity, and that shows up as combustion knock under load.
• Black smoke and poor powerUnder-fuelling on one cylinder usually turns into visible smoke and a loss of pulling power on hills.
• High return flow on the benchA valve that no longer seats cleanly appears straight away as excessive injector return flow during a return quantity test.
• Varnish or grooving on the seatHeat and pressure cycling can leave a varnished or grooved seat face, which is one of the classic control valve sticking symptoms.
• Fuel in the oil over timeA worn return path can thin the engine oil over a long period, which is how a small valve fault turns into a much larger repair.

These reports overlap with nozzle wear and with injector coding problems, so treat them as an early warning rather than a diagnosis. Confirm the fault on the bench and by return quantity before replacing anything. A code match plus a bench number is the reliable path; guessing from the symptom alone is not.

The list above covers the injector control valve symptoms that get reported first: excessive injector return flow past the seat, injector back leakage, and an injector misfire diagnosis that keeps coming back on one cylinder. Drivers usually notice a black smoke diesel engine or a hard start diesel engine long before a scan tool shows anything, and both are general diesel injector problems rather than signs unique to a valve. A diesel rough idle diagnosis is the one most often made at low mileage. The check that separates a valve fault from a nozzle fault is the injector return flow test on the bench.

1. 1. Remove and cleanPull the injector with the correct injector removal tool, then clean the body and bore before any valve work. Dust reaching a lapped face is the quickest way to ruin a new valve.
2. 2. Strip on a clean benchWork on a lint-free surface. Keep the cap and stem together, and note the characters cut into the cap before you disturb anything, because the cap face is where the code and the calibration characters live.
3. 3. Inspect the bore and seatCheck the bore and the seat face for grooves, varnish or damage under magnification. A scored seat needs more than a new valve set.
4. 4. Fit the matched setInstall the control valve as a matched pair and keep the side inlet port aligned as the injector body requires.
5. 5. Reassemble and codeReassemble the injector, fit new seals, and set the injector coding the ECU expects for the rebuilt unit. Torque and sequence follow the figures for that injector, not for the valve.
6. 6. Verify on the benchRun a return quantity and leak test on an injector tester before the injector goes back on the engine. Bench numbers, not road feel, tell you it is right.

The work is a bench job: keep the bench clean, keep the set matched, and let the numbers decide. If you would rather not rebuild in house, ask us what we can supply as a complete unit for your injector instead, or read the installation guide and the maintenance guide for the wider service routine, and our help centre for questions that are not about this code.

Two notes for workshops. An injector installation that ends with a valve swap still needs the unit coded, and the torque specification and sequence belong to the injector rather than the valve. The rest is bench discipline: careful disassembly, injector cleaning before anything is opened, and a common rail injector test bench to prove the result. None of that is specific to one valve code; it is standard diesel injector rebuild practice, alongside the other injector rebuild parts and the injector repair kit a bench works through.

Every F00VC01333 valve set carries a 6-month warranty against manufacturing defects. That cover applies to a valve that arrives out of tolerance or fails early because of how it was made. It does not cover damage caused by dirt, by incorrect fitting, or by a separate fault in the injector the valve is paired with. Like every injector spare parts warranty we issue, it is a supplier warranty from us and not a Bosch warranty.

The cover is component level: it applies to the valve set as supplied. It does not extend to the whole injector or to engine damage, and it is separate from any warranty on the injector you rebuild.

One point buyers raise. The F00VC01333 warranty is ours, issued by Vidishi Auto as the supplier, and it is not a Bosch control valve warranty: we do not sell Bosch-branded parts, and no Bosch warranty travels with this valve.

Caps and stems are handled in quantity on a rebuild bench, so this valve code is supplied from a 6 pc minimum rather than one at a time. We supply workshops, injector rebuilders and parts importers who need a dependable valve line rather than a one-off part, and larger rebuild quantities are quoted per order.

We act as a control valve supplier and as a wider common rail injector parts supplier for export, and we build this line ourselves as the injector valve manufacturer behind the Vidishi Auto brand. Injector control valve wholesale pricing is quoted per order from the 6 pc minimum, and a rebuild shop that also takes diesel injector parts in bulk can put several service lines on the same order.

For trade buyers: the F00VC01333 price is quoted per order rather than listed as a fixed figure, because valve pricing moves with quantity and with the service parts on the same order. The control valve moq is 6 pcs. We supply diesel injector parts bulk orders to an injector parts distributor as well as direct to rebuild benches, and we handle diesel parts wholesale and wider auto parts wholesale lines on the same export documentation.

The figures above are the packed export values for one unit. We do not list a bare valve size or a bare valve weight, because no source we trust gives one for this code and a specification table padded with approximations helps nobody. Control valve export shipping is quoted per shipment and lead time is quoted per order, and every injector parts export order leaves with its paperwork in place. Read our shipping information for freight options, and track your order once it ships.

A valve is a small part with an outsized effect on how an injector runs, so control valve quality is checked unit by unit rather than by sample. Each batch goes through an injector control valve inspection for stem freedom, sealing face condition and clean orifices. Rather than publish reviews we cannot verify, we describe how the part is inspected and let your test bench be the judge.

For a valve code with no published vehicle list, control valve technical support is not a nice extra — it is how the order gets placed correctly. It is free before you buy: send the valve code, the injector number and a photograph and we will check it against what we supply before quoting. Ordering the wrong valve is the most common way a rebuild goes wrong, so we would rather spend one message confirming the part than have you bench a valve that does not match. Support continues after delivery: bench figures, fitment questions and warranty claims all reach the same team.
