BORGWARNER (BERU) Car Parts
BERU products on this page cover petrol ignition and diesel cold-start systems. Ignition coils form the largest group, with ZS and ZSE references in connector, plug-top and other layouts. GE glow plugs follow in different lengths, threads, seats, voltages and connector forms. PSG003 and PSG004 add an integrated pressure-sensor function, while GSE108, GSE142 and GSE143 are glow-time control units. These parts interact with engine electronics, but each retains its own exact application and test procedure.
Begin with fault diagnosis and the complete BERU number, then confirm engine code, build data, system design and every electrical and mechanical interface. The current AutoMotoPart selection contains 23 BERU items, led by 13 ignition coil entries, 7 glow plug entries, 3 control unit, glow time entries. These BERU figures describe the range on this page rather than every product the brand may make elsewhere.
For an ignition coil, compare mounting, number of outputs, connector shape, terminal count, spark-plug connection and whether an output stage is included. A misfire code does not prove the coil is faulty; spark plug condition, wiring, supply, earth, injector, compression and control signals may also be involved. Ignition systems generate hazardous voltage, so isolate and test only through approved equipment and procedures.
For glow plugs, match rated voltage, design, thread, length, fitting depth, seat angle, spanner size and connector. Never apply battery voltage directly to a low-voltage glow plug or a pressure-sensor type. Carbon and corrosion can make removal hazardous, and a snapped plug can create major engine work. Follow current BERU and vehicle instructions for engine temperature, release method, channel cleaning, installation lubricant where specified and exact torque. Protect the PSG connector and do not grip it with pliers. A controller must match the full glow system, not merely the number of cylinders. Clear faults and verify cold-start operation only after the circuit and power supply are checked. The products below are a reference guide; final suitability comes from current application and repair data.

BERU: understand the range before choosing
BERU is BorgWarner's ignition and diesel cold-start brand. BorgWarner officially distributes BERU glow plugs, glow plug control units and ignition coils in the European aftermarket, which is exactly the three-part selection shown here. The collection is reference-led and electrically specific: thirteen coils, seven glow plugs and three glow-time control units cannot be selected safely from vehicle name or appearance alone.
AutoMotoPart currently lists 23 BERU items. The largest BERU groups are 13 ignition coil entries, 7 glow plug entries, 3 control unit, glow time entries. BERU totals can change, so a category count is orientation rather than proof that a particular reference suits a vehicle, workplace or job. The exact BERU listing, its current technical information and the item in front of you must agree.
What the BERU page actually covers
| Product group in this range | Current entries | Selection focus |
|---|---|---|
| Ignition Coil | 13 | Confirm BERU reference, engine/build, electrical system, connector, mounting, dimensions, related components and exact test or installation procedure. |
| Glow Plug | 7 | For glow plugs include rated voltage, thread, reach, seat, connector and pressure-sensor status. |
| Control Unit, glow time | 3 | For controllers include supply, connector, number and type of plugs, diagnostics and system coding or adaptation requirements. |
The product balance mirrors BERU's official aftermarket families, yet the references remain diverse. Coil codes begin ZS or ZSE, conventional glow plugs GE and pressure-sensor examples PSG, while controllers use GSE. Prefixes help locate the family but are not enough to prove a vehicle application. Record the entire code and do not discard an original part before interfaces are compared.
Build a reliable shortlist
Treat the failed system as a circuit. Petrol ignition runs from supply and control through the coil, connector and spark plug; diesel preheating runs through power supply, controller, harness and individually specified glow plugs. A fault can sit anywhere in those paths. The table helps build evidence before parts are disturbed.
| Check | Why it matters | Useful evidence |
|---|---|---|
| Engine identity | Different engines in one model use different coil or glow architectures | VIN-derived build, exact engine code and current BERU application |
| Electrical rating | A physically matching low-voltage glow plug can be damaged by the wrong supply | BERU rated voltage and system/controller information |
| Connector | Pins, latch, keying and integrated electronics must agree | Undamaged harness plug and complete terminal drawing |
| Mechanical fit | Thread, reach, seat, coil boot and mounting govern location | Published dimensions and known-correct removed component |
| Special function | Pressure sensing or output-stage integration changes diagnosis and handling | PSG, controller and coil feature statement for the exact number |
| Repair data | Removal limits, torque and post-fit checks vary by engine | Current BERU instruction and vehicle workshop procedure |
Cross-references can build a shortlist but cannot overrule a voltage, thread or connector mismatch. If the removed part disagrees with current application information, check whether the engine, cylinder head, harness or control system has been changed. Do not make an incompatible plug or coil fit by altering terminals, boots or threads.
Ignition coils and high-voltage diagnosis
BERU ignition-coil examples vary by pin count, connector style, spark-plug connector and inclusion of an output stage. Some mount directly over a plug; others can serve a different ignition arrangement. Keep cylinder position and connector labels organised if multiple coils are removed, and compare boot length, seal and mounting before installation.
Diagnose a misfire without swapping parts blindly. Check the relevant spark plug, harness condition, supply, earth and signal through approved test methods and consider fuel or mechanical causes. Do not disconnect a coil on a running engine unless the vehicle procedure explicitly permits it. High voltage can cause injury and can damage modules or insulation when an improvised spark gap is created.
Glow-plug voltage, dimensions and seat
Several BERU GE examples in the collection are rated at 4.4 volts, yet their lengths, threads, fitting depths, current and seat angles differ. The vehicle controller manages that design; connecting one directly to a nominal 12-volt battery is unsafe and can destroy it. Use a meter and test method suitable for the circuit and pressure-sensor electronics.
Thread diameter and pitch must match the cylinder head, while fitting depth positions the heating element in the chamber. An incorrect reach or seat can leak, contact internal parts or leave the tip in the wrong thermal environment. Screw a new plug by hand initially and stop at any resistance that suggests crossed threads or carbon, then use only the specified installation torque.
Pressure-sensor glow plugs
PSG003 and PSG004 combine glow and combustion-pressure sensing functions. Their extra connector and internal electronics make handling different from a conventional pencil plug. Match the exact PSG reference and engine system, retain the protective cap for the stage described by BERU and release the harness connector manually as the official guidance states.
Do not probe, twist or strike the sensor connector and do not use pliers to pull it. Pressure-signal faults can involve wiring, controller or engine conditions as well as the plug. Following replacement, inspect the connector lock, route the harness without strain and use the vehicle diagnostic procedure to check stored faults and live behaviour.
Glow-time control units and circuit faults
GSE control units switch and monitor a defined glow system. GSE108, GSE142 and GSE143 are separate references, not three generic relays. Compare the connector, mounting, electrical architecture, supported glow plugs and vehicle application. Water entry, poor power supply, earth faults or shorted plugs can damage or mislead the controller diagnosis.
Before replacement, test battery state, fuses, main feed, earth, harness and individual plug circuits through current workshop information. Do not bypass a controller with a direct cable or fit a higher-rated fuse. After installation, secure the unit against heat and moisture, restore every connector lock and perform coding, adaptation or fault clearing only where the vehicle procedure requires it.
Removal, installation and completion checks
Glow-plug removal should be planned before force is applied. BERU publishes specific workshop guidance on release, engine warming, penetration, channel cleaning and torque. Use the procedure applicable to that plug and engine, respecting the stated breaking limit. If the plug will not move within the safe method, stop and use specialist extraction support rather than snapping it in the head.
Keep debris out of the combustion chamber, clean the bore and thread with the approved tooling and use installation grease only when specified. Coils need clean, dry plug wells and intact seals; glow plugs need correctly seated connectors. Reassemble covers and routing, then verify starting, idle, misfire or glow faults and warning lamps. A cleared code without a complete drive or cold-start check is not proof of repair.
From identification to a checked result
| Stage | Good practice for this range | Mistake to avoid |
|---|---|---|
| Diagnose circuit | Test supply, wiring, plug/coil, controller and mechanical causes | Replacing BERU parts from one fault code |
| Identify | Record full reference, engine, voltage, connector, dimensions and function | Using a ZS, GE, PSG or GSE prefix as final fitment |
| Prepare | Obtain exact removal, torque, isolation and diagnostic procedures | Applying direct battery power to test an unknown glow plug |
| Remove and fit | Protect connectors, threads, bores and high-voltage components | Exceeding release torque or forcing cross-threaded parts |
| Verify | Check faults, live operation, warning state and a relevant cold or running test | Assuming a cleared code proves the system |
Record the full BERU number and cylinder or module position along with measured fault evidence and tightening data used. That traceability is particularly important when multiple plugs or coils look identical and when a PSG pressure signal or controller fault needs comparison after the repair.
Reading real BERU references
The BERU names below are examples from the current range and show why the complete description matters. They are not universal BERU recommendations and should not be treated as a fitment list. Within BERU, a shared family word can conceal a different dimension, connector, material, pack format, operating condition or installation side.
| Example listing | What to verify beyond the name |
|---|---|
| Beru GE133 Glow Plug | GE133 rated voltage, M10x1 thread, 130mm length, 28mm depth, 63-degree cone and connector |
| Beru ZS029 Ignition Coil | ZS029 mounting and four-connector description, three pins, voltage and distributor system |
| Beru ZS549 Ignition Coil | ZS549 single output, three pins, included plug connector and coil-well dimensions |
| Beru ZSE144 Ignition Coil | ZSE144 spring contact, output stage, three pins, boot and exact engine application |
| Beru GE110 Glow Plug | GE110 4.4V rating, 97mm length, M10x1 thread, 25mm depth and emissions-system application |
| Beru GE117 Glow Plug | GE117 4.4V rating, M10x1.25 thread, 137mm length, 121-degree cone and engine code |
| Beru PSG004 Glow Plug | PSG004 sensor function, connector, M10x1.25 thread, 168mm length and handling method |
| Beru ZS247 Ignition Coil | ZS247 SAE connector, pin count, distributor equipment and mounting arrangement |
These examples show large differences inside one short product family. GE110 and GE117 share nominal voltage but not thread pitch, length or seat; PSG004 adds a sensor; ZS coils vary in connector and ignition arrangement. Use the complete BERU specification rather than a photograph or leading letters.
Common errors around BERU products
- Choosing a BERU coil or glow plug from make, model and a similar image without engine data.
- Applying 12 volts directly to a 4.4-volt glow plug or a pressure-sensor plug.
- Treating every glow fault as a failed plug without checking controller, supply and harness.
- Pulling a PSG connector with pliers or removing its protective cap too early.
- Forcing a glow plug past its safe removal limit and breaking it in the cylinder head.
- Using a generic torque based only on thread diameter instead of the exact part procedure.
- Swapping coils without recording cylinder position and moving the fault evidence.
- Bypassing a glow controller or increasing a fuse rating to make the circuit operate.
BERU questions and answers
Q: What BERU products are on this page?
A: The range contains ignition coils, conventional and pressure-sensor glow plugs, and glow-time control units.
Q: Is a misfire code proof of a bad coil?
A: No. Check plug, wiring, supply, injector, compression and control evidence through the vehicle procedure.
Q: Can coils be swapped between cylinders for diagnosis?
A: Only where the approved method permits it, with positions recorded and high-voltage safety maintained.
Q: Why does glow-plug voltage matter?
A: Modern low-voltage plugs are controller-driven and can be destroyed or become hazardous if connected directly to 12 volts.
Q: Is thread size enough to choose a glow plug?
A: No. Voltage, reach, seat, connector, current, design and engine application must also agree.
Q: What is a BERU PSG glow plug?
A: It combines a glow function with combustion-pressure sensing and requires its exact electronics and handling procedure.
Q: Can a PSG connector be pulled with pliers?
A: BERU guidance says to release it manually and avoid tools such as pliers.
Q: Should all glow plugs be replaced from one controller fault?
A: Not without diagnosis; test the plugs, circuits, supply, earth and control unit as the system requires.
Q: Can a glow controller be bypassed?
A: No. Direct bypass can damage low-voltage plugs, wiring and electronics and defeats system protection.
Q: What if a glow plug exceeds the safe release limit?
A: Stop and follow the approved staged or specialist extraction route rather than continuing until it breaks.
Q: Is installation grease always required?
A: Use only the lubricant and location specified for the exact BERU plug and vehicle procedure.
Q: What confirms a successful repair?
A: Correct reference and installation plus fault, live-operation, warning and relevant starting or running checks.
