Trouble Codes Often Seen on Vehicles Equipped with the Mitsubishi TD04HL

These are generic diagnostic trouble codes commonly associated with turbo boost control issues on this application. They’re triggered by the vehicle’s ECU, not the turbo itself, so confirm with a scan tool before assuming the turbocharger is at fault. What each code means is on our list of turbocharger fault codes.

• P0299 — Turbocharger/Supercharger Boost Pressure – Low (underboost)
• P0234 — Turbocharger/Supercharger Overboost Condition

Also Known As

The TD04HL is sold in many versions, and buyers search for it under several names.

• Mitsubishi TD04HL-15T, TD04HL-16T, TD04HL-19T
• Volvo T5 turbo
• Saab Aero TD04 turbo
• Hyundai / Kia 2.0T turbo (TD04HL4S)
• TD04 high-flow turbocharger
• TD04HL turbo cartridge / CHRA

Vehicles and Engines Fitted With the Mitsubishi TD04HL

The TD04HL is the larger-turbine member of the TD04 family. It is not the Subaru WRX or Forester XT turbo: those cars use the smaller TD04L.

Volvo and Saab

• Volvo 850, S70, V70 and C70 with the turbocharged five-cylinder (T5 and related models)
• Saab 9-3 (first generation) and 9-5 Aero (TD04HL-15T)

Hyundai, Kia and Others

• Hyundai Sonata, Santa Fe and 2013-on Genesis Coupe 2.0T; Kia Optima and Sportage 2.0T (TD04HL4S versions)
• Porsche Cayenne and Panamera 4.8L twin turbo
• Acura RDX 2.3L

Compact Diesel Equipment

• Kubota V3800
• Caterpillar 3044C, C3.4 and 3064 in loaders and excavators
• John Deere PowerTech 4024 and 5030
• Yanmar and Isuzu 4BG1T industrial engines

Versions share the name but not the housings, so the number on the tag decides which parts are right.

Common Mitsubishi TD04HL Failure Symptoms

• Blue or gray smoke under boost, especially on a long pull
• Blue smoke on startup or after idling; check the crankcase breather, oil drain and engine wear before blaming the turbine-side seal
• In-and-out shaft play when checked by hand, or a wheel that touches its housing
• A high-pitched whine or grinding from the center cartridge as the bearings wear
• Overboost, or boost that creeps past target
• Slow or inconsistent boost from a sticking wastegate, or overboost from a split actuator diaphragm
• Oil consumption with no external leak
• Oily residue inside the charge pipe or intercooler inlet

How the Mitsubishi TD04HL Usually Fails

The TD04HL is a journal-bearing, wastegated turbo, and it fails the way that design does.

• Turbine-side seal leakage. Oil passes the seal into the hot exhaust and shows as blue smoke under load.
• Journal and thrust bearing wear from extended oil change intervals. Once the oil breaks down the bearings score and the shaft develops play.
• Wastegate actuator wear. The diaphragm and rod wear, the gate no longer holds its set point, and boost creeps or falls short.
• Oil starvation from a coked or restricted feed line, which damages bearings and seals together.
• Compressor wheel rub once worn bearings let the shaft move far enough for the wheel to touch the housing.
• Heat soak on engines shut off hot after hard running: carbon builds around the seals and speeds up the oil leak.

Preventing Future Mitsubishi TD04HL Failures

Most TD04HL failures come down to oil quality and heat management, and both are easy to stay ahead of.

• Change oil on schedule with the grade the engine maker specifies, and sooner if the engine is driven hard
• Let the engine idle a few minutes after hard driving before shutting it off
• Let the engine reach operating temperature before using full boost
• Inspect the oil feed line and renew it if it shows coking or restriction
• Keep the crankcase ventilation system clear: a blocked breather pushes oil past the turbo seals
• Check the intake and charge piping for boost leaks
• Keep a clean air filter and a sealed intake tract

Common Mitsubishi TD04HL Upgrade Paths

Owners rebuilding a TD04HL ask about a larger compressor wheel on the same frame (the 19T is the usual step up on Volvo and Saab engines), a 360-degree thrust bearing for higher boost, and a billet compressor wheel in place of the cast one. What suits your car depends on tuning and supporting modifications. For equipment engines a stock-specification rebuild is the right choice.

Frequently Asked Questions

How to Identify Your Mitsubishi Turbo

The identification tag is typically located on the compressor housing of the turbocharger. It usually lists the model number, assembly number, and serial number. If you’re not sure which Mitsubishi model you have, send PT Turbo a photo of the tag and we’ll help identify it before you ship anything.

PT Turbo Inspection Process

Every turbocharger goes through the same evaluation before any work begins:

1. Initial evaluationcompressor wheel, turbine wheel, shaft, bearing housing, VGT assembly (if equipped), actuator, and seal surfaces are checked first.
2. Complete disassemblythe turbocharger is fully torn down and every major component is inspected individually.
3. Cleaningcomponents are cleaned to remove carbon, oil residue, rust, and contamination.
4. Measurementcritical tolerances are measured against OEM specification.
5. Reassemblyrebuilt using new wear components matched to your specific model.
6. CIMAT VSR balancingthe rotating assembly is balanced in-house, with a balance report included.
7. Final inspectionleak test, visual inspection, and actuator or wastegate function check before shipment.

No work begins without your approval. You receive a quote after inspection, not before.

Pricing

Most rebuilds require inspection before final pricing. Standard rebuild pricing depends on the turbo model, parts availability, wheel condition, shaft condition, housing damage, and whether upgrades are requested. PT Turbo inspects every turbo and sends a quote before any work begins — no surprise charges.

Mitsubishi TD04HL turbo rebuilds start at $575. We inspect the turbo first and confirm the exact price with you before any work begins. See our turbo rebuild price list for the standard price of each turbo we rebuild.
