NG eCall (Next Generation emergency call) is the EU‑mandated automatic emergency‑call system for new vehicles. After a crash or manual trigger – the system automatically sends location, time, and basic vehicle data to the 112 rescue platform.

There are two generations:

·CS eCall: relies on 2G/3G circuit‑switched networks.

·NG eCall: based on IMS – using 4G/5G data channels.

The two are not directly compatible – the EU has set clear transition dates. After the old scheme expires – new projects are no longer accepted – companies must complete architecture adjustments in advance – otherwise new vehicles miss access – affecting production schedules.

1. Validity – Basic Rules

Separate component STU (Separate Technical Unit) and whole‑vehicle WVTA (Whole Vehicle Type Approval) – compliance requirements differ. In practice, components and vehicles are often handled by different teams – poor communication creates compliance gaps. Plan both tracks together from the start – assign responsible contacts for modules and vehicle models.

1.1 Component level

·UN R144 STU component certificates: no fixed expiry – as long as the design is unchanged and CoP (Conformity of Production) is maintained – the certificate remains valid.

·Some Notified Bodies may impose 3‑year CoP surveillance reviews – this is internal – not a regulatory renewal.

·When standards are updated: difference assessment required – supplementary testing may be needed.

·Transition‑period NG eCall certificates issued under CEN/TS versions must be updated by 2028.

1.2 Whole‑vehicle level

·Vehicle approval follows WVTA – valid as long as the model is in production.

·If a facelift changes the eCall module, antenna, or core firmware – a change/extension assessment is required – the old WVTA cannot be reused – a common trap.

  2. Key Dates

Wrong dates disrupt SOP – maintain a dedicated project tracker – don't rely on memory.

2.1 CS eCall sunset

·From 1 January 2026: no new CS eCall applications or extensions.

·From 1 January 2027: no new CS eCall vehicle type approvals.

Already‑approved, CoP‑compliant production models may continue production/registration – no immediate sales ban. Projects still using 2G/3G must upgrade to IMS architecture.

2.2 New standards mandatory

·EN 17184:2024 and EN 17240:2024 – new applications submitted after 1 January 2027 must use them.

·Transition certificates under CEN/TS 17240:2018 must be updated by 2028.

Module suppliers should include these tests in product planning early – don't leave them to the last minute.

  3. Renewal and Change – Lead Time

Regulations do not have a "renewal expiry" – it's about standard updates and product changes requiring difference/extension assessments. Leaving it to the last minute – lab slots are tight – full retesting may be required.

Based on industry practice – for standard transitions or major product changes – allow at least nine months buffer. With sufficient time, existing test data can be reused for difference assessment – without it, full retesting causes approval gaps.

From 2027, new applications must assess backup‑battery endurance – modules must include this at development stage. Missing it blocks new applications and difference updates – late‑stage lab scheduling is extremely tight.

  4. Technical Files and Regulatory Compliance

Getting the certificate is not the end – document archiving is a long‑term compliance obligation. Staff turnover often causes document gaps – regulatory audits without complete files = non‑compliance.

·UN R144 base retention: at least 5 years.

·Whole‑vehicle WVTA and some transition NG eCall projects: 10 years.

Establish archiving processes – ensure document handover during staff departures.

Regulations: EU 2017/79, EU 2024/1180, EU 2025/1871 – these are continuously updated – always refer to official texts – don't rely on second‑hand information.

  5. BlueAsia's End‑to‑End Approach

BlueAsia can provide full NG eCall compliance services – standard‑transition assessment, test scheduling, and technical‑file archiving. We get involved at the facelift stage – planning eCall work in parallel. Pre‑assess IMS architecture switching and backup‑battery new rules – ensuring timely project delivery.

  6. Common Misconceptions and Practical Reminders

·Component STU certificates do not have a statutory 3‑year renewal – NB 3‑year CoP surveillance is not renewal.

·CS eCall deadlines only affect new certification projects – compliant in‑production models may continue – no blanket sales ban.

·Major eCall module, antenna, or firmware changes – the whole vehicle must go through change/extension – old WVTA cannot be reused.

·Document retention varies by scenario – not all eCall files require 10 years.

·For standard transitions or product changes – allow nine months buffer – avoiding full retesting and approval gaps.
