VW T6.1
EA288 diesel with 66 kW, entry engine of the T6.1. Delphi injection, extremely underpowered for the van.
Too weak for T6.1
CXGD with 90 hp in the T6.1 is significantly underpowered. Not suited to heavy transport tasks.
Engine Weaknesses 4
EA288 in the T6.1 retains high-pressure EGR. Despite revisions, coking with short trips remains an issue.
Symptoms: Engine warning light, power loss, limp mode
The CXGD 2.0 TDI (110 kW, VW T6.1) shows at higher mileage combined particulate filter clogging and injection quantity deviations between cylinders. Different injector calibration values amplify uneven combustion and place additional load on the DPF.
Symptoms: Juddering and power loss under load, DPF warning, rough idle, different injection quantities in VCDS
The CXGD/CXGE T6 engines share the typical EA288 weakness of coked EGR valves. Short-trip use promotes deposits that jam the valve guide and trigger faults.
Symptoms: EGR fault code, juddering, power loss, increased fuel consumption
On the T6.1 too, the G450 pressure sensor is reported as an early failure cause.
Symptoms: Engine warning light, increased fuel consumption
Vehicle Weaknesses 8
Water ingress can cause Bowden cables in the door locking system to freeze in frost, creating a false lock. In the worst case doors open while driving. Recall 57H5/57I1 affects approximately 76,000 vehicles (build years 2019–2021).
The T6.1 electric sliding door uses fully electronic lock control with no mechanical backup. If the control unit fails — often due to a fully discharged battery — the door no longer responds.
Control arms made of unprotected grey cast iron as well as the underbody and cavities show initial rust formation after just 2–3 years. The factory sealant is considered inadequate. Professional corrosion protection is recommended immediately after purchase.
The diesel particulate filter only regenerates after approximately 15 minutes of motorway driving at over 600°C. With predominantly short-trip use, the filter fills up and from approximately 150,000 km causes knock-on failures. Oil dilution from post-injection possible.
The lower sliding door guide rail rusts through water accumulation and paint abrasion from the running roller. Surface rust sets in from the first winter. A known serial issue since T5/T6.
The slotted rubber bushings in the front control arms of Multivan/Comfortline variants wear significantly faster than the solid rubber variant in the Transporter. Knocking noises sometimes from 20,000 km.
The MIB3 infotainment system in the T6.1 freezes or restarts every 2–3 minutes. Without a firmware update or hardware replacement the problem returns.
The Webasto auxiliary heater in the T6.1 Multivan shuts off after a few seconds on its own. Common causes: too weak an auxiliary battery, empty tank, or CAN bus communication errors. Safety lockout requires diagnosis and reset.
