2 known faults with sources

VAG plug-in hybrid high-voltage systemHigh-voltage system

Engine / equipment: MQB and MLB plug-in hybrids: Golf GTE/eHybrid, Passat GTE, Tiguan and Arteon eHybrid, Multivan T7, Audi TFSI e, Seat and Cupra e-Hybrid, Skoda iV
Period mentioned: 2019–2023
Symptoms: Usually none. In rare cases, overheating or fire in the engine bay or battery.
Possible cause described: In 2022 the VW Group recalled about 118,000 plug-in hybrids over a high-voltage system fuse that could fail under overvoltage and insufficient insulation; an extra insulating mat is fitted. In 2024 Audi added a recall for 2022–2023 Q5 and A7 plug-in hybrids over battery faults.
Check for the garage: Confirm by VIN at the dealer that the high-voltage system recalls have been done.
Cost cited in the source: Free under the recallsA rough figure from the original database, not an up-to-date quote.

Applies if: Only if fitted with the air conditioning system described.

A/C not cooling: N280 valveClimate control

Engine / equipment: Air conditioning with clutchless compressor and N280 regulating valve (combustion VW, Audi, Seat, Cupra and Skoda from 2006)
Period mentioned: 2006–2026
Symptoms: The air does not cool or cools intermittently (for example only at motorway speed), and sometimes the compressor rattles with the A/C on. Codes 01232 (N280 valve), P2612 or 00898.
Possible cause described: The compressor regulates its output with the N280 solenoid valve, its most common failure point. Audi issued technical bulletins over a manufacturing fault in this valve on Sanden compressors. Its connector can also become brittle and corrode (especially without the engine undertray), or the wiring fails.
Check for the garage: Read the codes and N280 control current with VCDS or ODIS, measure its resistance (about 10 ohms) and check the connector and wiring before replacing parts. If the valve or compressor is replaced, the whole circuit must be flushed.
Cost cited in the source: N280 valve: a cheap part (about 30 dollars) where sold separately; new compressor with circuit flush: considerably moreA rough figure from the original database, not an up-to-date quote.
