AdBlue compensation: the Stellantis 4UA/4UB repair scheme is not the online platform

Since the European Commission announced on 20 December 2024 that Stellantis had committed to address AdBlue/urea tank cases, owners have been directed to the support platform stellantis-support.com. That platform exists, but it is not the main route for an owner whose car has not yet been repaired. Two distinct schemes are in place, and confusing them can delay a repair or lead to a refusal.

What the European commitment covers

The commitment followed an inquiry by the CPC consumer protection authorities, prompted by BEUC after the Italian authority AGCM examined similar issues in 2023. Stellantis announced the campaign in January 2025 for 29 countries. The affected vehicles are Euro 6 diesel cars with SCR systems, built between January 2014 and August 2020.

Two schemes, two purposes

• Special coverages 4UA/4UB. These apply at the repair. For vehicles under 5 years and up to 150,000 km, parts are covered at 100% (4UA). From 5 to 8 years or over 150,000 km, part coverage follows the published 4UB grid: from 90% up to 30,000 km down to 30% in the 180,001–210,000 km band, and no cover above 210,000 km. A €30 labour contribution has been added since December 2023. This is the coverage an owner should mention when booking an authorized repairer.
• The platform stellantis-support.com. This is a retroactive compensation tool, limited to owners who have already had the repair done after 1 January 2021 and have already received a contribution under an earlier special coverage. The amounts are €50, €100 or €200. If the repair has not yet been done, the platform is not the right route; a request submitted in those circumstances is refused, and that refusal does not affect the 4UA/4UB entitlement at the workshop.

Proving eligibility

The criterion is the date of manufacture, not the registration date. A first registration before August 2020 is accepted as proof, because a vehicle cannot be registered before it was built.

What to check before accepting

The Stellantis Urea Tank terms dated 11 June 2025 state, at point 7, that accepting compensation requires a declaration of satisfaction and a waiver of any claim related to the urea tank. Owners should read this carefully before signing.

The implementation is monitored. The CPC network has said it is following the roll-out, and national authorities can act if commitments are not honoured. Under the earlier Italian scheme, Altroconsumo reported in May 2024 cases of calculation errors and non-payments.

If confronted with an AdBlue/SCR failure, ask the authorized repairer to check the 4UA/4UB coverage. If the repair has already been paid for, keep the invoice and check the platform criteria. For legal options, consumer protection and hidden-defect law may apply.

If you own a Peugeot, Citroën, DS or Opel affected by an AdBlue failure, you can register your case on adblue-haldex.com. The register is independent and helps document the issue.
