Component pages
Canonical pages for duplicated reports.
Each card groups repeated reports into one reusable data record. Exact fitment should
still be confirmed by VIN, installed connector and part photos.
Early HE400VG variable-geometry turbo used on DAF XF/CF MX engines. The repeated reports point to hot-side vane binding, actuator travel errors, oil-coked bearings and underboost complaints.
Common symptoms
- Loss of power uphill or under trailer load
Later HE400VG turbo group for DAF XF/CF MX-13 and selected MX-11 Euro 6 applications. Main search intent is OEM replacement matching plus diagnosis of underboost, VGT actuator errors and bearing wear.
Common symptoms
- Loss of boost above 1200 rpm
HE500VG turbo group for high-output DAF MX-13 Euro 6 trucks. The reports repeatedly connect these OEM numbers with VGT actuator mismatch, soot-bound vanes, bearing wear and smoke complaints.
Common symptoms
- Significant power loss above 1100 rpm
High-output MX-13 530 hp HE500VG turbo group. Useful for exact OEM searches around 2117463, 2301181, 2353021 and 2403671.
Common symptoms
- Strong turbo lag then a hard boost surge
Electric VGT actuator used with Holset HE400VG and HE500VG turbochargers on DAF MX Euro 6 engines. It is often blamed for boost faults, but the source reports stress that the turbo vane mechanism must be checked first.
Common symptoms
- Truck in limp mode with RPM capped around 1300
Main MX-13 Euro 6 EGR valve interchange group. It combines repeated reports for 2339622 and linked replacements where symptoms are soot blocking, position errors, failed regens and derate.
Common symptoms
- Power derate or limp mode
Pierburg-supplied MX-11 Euro 6 EGR valve group. The main user intent is matching OEM numbers and understanding repeated failure symptoms from soot, actuator wear and DPF regeneration problems.
EGR valve group reported for XF/CF Euro 6 applications. Use this page for searches around 2123995, 2187602, 2256375 and Pierburg 7.04253.88.0.
Common symptoms
- Coolant loss without external leak
Earlier EGR valve interchange group from the reports. Fitment was not fully specified, so use this as a lookup and diagnostic content page, not as a final fitment guarantee.
Common symptoms
- Rough idle or stalling at low speed
MX-11 EGR valve report group using OEM 2104977 and related numbers. These same numbers also appear in a BPV report group, so exact OEM lookup should show both possible matches and request VIN/photo verification.
Common symptoms
- Limp mode after cold start
Back pressure valve report group for MX-11/MX-13 Euro 6 applications. The same OEM number appears in turbo reports too, so this page deliberately exposes the ambiguity and asks users to verify by VIN or photo.
Common symptoms
- Distinct lack of power under load
MX-13 Euro 6 BPV valve group from the repeated reports. Searchers usually need to match an OE number and understand weak engine-brake, chuffing exhaust and derate symptoms.
Common symptoms
- Engine brake suddenly weak or completely dead on descents
Earlier MX-13 Euro 5 back pressure valve group for XF 105 and CF 85. Use this page for 1840165 and related PE/PEX search terms.
Common symptoms
- Loss of pull with a trailer on rolling roads
HY35W wastegated turbo group for DAF LF and CF with Cummins ISBe 5.9L engines. Failure patterns are mainly shaft play, oil starvation and sticky wastegates.
Common symptoms
- Lazy boost rise and smoke between shifts
HX35W turbo group for DAF LF with Cummins ISBe6 6.7L engines. The repeated reports focus on bearing and seal failure, oil in charge pipes and underboost on motorway grades.
Common symptoms
- Black smoke under throttle from underboost
Fuel / brake / bypass valve 4 refs
B368 bypass valve data is reported in several ways: fuel bypass, wastegate/bypass valve and EGR cooler bypass actuator. The lookup page should therefore make the ambiguity visible and route users by fault code and symptom.
Common symptoms
- Reduced motor power and lazy spool-up
Fuel / brake / bypass valve 10 refs
Cylinder 1 unit pump solenoid group for DAF DMCI/EUP systems. Intended for searches by B131, P0201, P0261, P0262 and related pump-unit assembly numbers.
Common symptoms
- Engine misfire on cylinder 1
Fuel / brake / bypass valve 7 refs
Cylinder 2 pump unit solenoid group for DAF DMCI/EUP systems. Structured for OEM and P-code lookup around B132, P0202, P0264, P0265 and P0266.
Common symptoms
- Cylinder 2 misfire and vibration at idle
Fuel / brake / bypass valve 6 refs
Cylinder 4 unit pump solenoid group for DAF DMCI/EUP systems. Focuses on cylinder 4 misfire, P0204/P0270/P0271 fault code searches and high-mileage solenoid failures.
Common symptoms
- Cylinder 4 diesel knock under acceleration
Fuel / brake / bypass valve 3 refs
Cylinder 1 MX engine brake solenoid group. Searches usually combine B411 with P3405, P3407 or complaints about weak engine braking.
Common symptoms
- MX engine brake retard force reduced
Fuel / brake / bypass valve 1 refs
Cylinder 3 MX engine brake solenoid group. Intended for B413, P3421, P3423 and P3424 searches plus diagnosis of intermittent retarder complaints.
Common symptoms
- Engine brake force markedly reduced
Fuel / brake / bypass valve 1 refs
Cylinder 4 MX engine brake solenoid group for B414 and P3425/P3427/P3428/P3429/P3431/P3432 searches.
Common symptoms
- MX engine brake noticeably weaker than normal
