The 43rd session of the IWG on PTI convened on 8 May 2026 in Brussels. The group reaffirmed the need to strengthen integration between type approval and in-use inspection per WP.29 Whole-Life Compliance framework (WP.29/2023/89). At least 20 UN Regulations contain incomplete, non-harmonised PTI provisions. The IWG agreed to add “Review of PTI provisions in UN Regulations (1958 Agreement)” to its Action Plan and submit a proposal to WP.29 requesting endorsement. Work on diagnostic tools in PTI and automated vehicles inspection continues. The group reviewed recent amendments to UN Regulations Nos. 13 and 13-H for new braking technologies and identified challenges regarding LED replacement light source inspection.

The agenda includes:

• Coordination and organization of work,
• Pollution emission control in PTI covering PN measurement, NOx measurement, and Euro 7,
• Advanced Driver Assistance Systems and Automated Driving Systems using diagnostic devices for in-vehicle data access,
• Periodical technical inspections of automated vehicles,
• PTI provisions for brakes, lighting devices coordination approval and inspection,
• 1997 Agreement updates,
• Any other business including R.E.1 document from WP.1,
• Next meetings.

The Informal Working Group on PTI held its 43rd session on 8 May 2026, focusing on whole-life compliance implementation and review of PTI provisions in UN Regulations. The group confirmed that at least 20 UN Regulations contain incomplete, non-harmonised, and sometimes outdated PTI provisions. The IWG agreed to review PTI provisions in UN Regulations, submit proposals to WP.29, consult relevant GRs on suitable inspection methods, and develop targeted amendments to priority Regulations. Work continues on ePTI using diagnostic devices, PTI of automated vehicles, braking system provisions for new technologies, and LED lighting inspection challenges.

PTI IWG activities include:

• Reviewing NOx measurement and emissions testing,
• assessing implications of new Euro 7 UN Regulations (Nos. 179 & 180),
• continuing work on diagnostic devices in PTI (ePTI),
• discussing PTI approaches for automated vehicles,
• reviewing new braking technologies,
• identifying inspection challenges for LED lighting systems,
• launching a review of PTI provisions in UN Regulations,
• consulting relevant GRs on inspection methods,
• developing amendments for priority UN Regulations,
• submitting proposals to WP.29 for endorsement.

LED replacement light sources without type approval are being sold online and offline and are unsafe for public roads; vehicles equipped with such products would fail PTI. LED replacement light sources with type approval are available either at national level or according to UN R37, and are safe and legal for public roads; vehicles equipped with approved LED replacement light sources shall NOT fail PTI. Approval marking on installed light sources is not accessible during PTI; verification may involve a sticker on headlamp housing, type approval documents, or packaging, with removal of the light source as a last resort to verify the approval marking.

Single N₁ and N₂ vehicles with fluted brake drums for parking brakes cannot be inspected on roller and plate test benches or in test drives. Electric parking brake systems cannot be tested on roller and plate test benches or test drives, and wheels cannot be turned on lifts to inspect for damages or bearing wear. Some vehicles have hydraulic braking systems with brake fluid reservoirs not accessible without dismantling or special tools, requiring removal of covers, fasteners, and screws to access brake fluid for inspection. PTI inspection provisions require updating to address these vehicle design variations.

The meeting will address coordination of work, pollution emission control in PTI including PN measurement, NOx measurement, and Euro 7, Advanced Driver Assistance Systems and Automated Driving Systems including PTI using diagnostic devices and inspections of automated vehicles, PTI provisions for brakes, lighting devices coordination and inspection, and 1997 Agreement updates.
