AdBlue® & Haldex® Pump Issues
The national portal for reporting and registering vehicle manufacturing defects. Faced with abusive repair bills, let's gather evidence to force manufacturers to take responsibility.
AdBlue®: what the trademark covers
VDA licenses the AdBlue® trademark to carmakers “for marketing purposes”. The fluid is governed by a standard. The tank that holds it carries the same brand.
The AdBlue Scandal (SCR System)
Common defects: Urea crystallization, tank deformation, pump or injector failure (P20E8 fault codes).
Consequence: Warning message with a countdown blocking the engine start. A full replacement quote is often imposed.
Precedent: Under pressure, Stellantis had to implement a refund grid (up to 8 years). We demand that this rule applies to all manufacturers.
The Haldex Pump Trap
Common defects: Rear axle electro-hydraulic pump failure due to clogging of the mesh filter.
Maintenance Fault: Some manufacturers (including JLR, Volvo...) sold this oil as "filled for life," effectively prohibiting its replacement.
Consequence: Forced premature wear due to the lack of recommended maintenance. This is an actionable documentary design defect.
⚖️ Legal Procedure
The strategy is based on **Hidden Defects** (Manufacturing defects) laws. Recommended steps:
- Formal notice (Certified Mail) to the manufacturer's headquarters.
- Independent expert evaluation if the refusal persists.
- Small claims court filing or mediation.
Important: Do not repair before having documented proof or an agreement.
