2 known faults with sources
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.

Poor starting with implausible temperature signalEngine management
- Engine / equipment
- New Beetle coolant sensor and wiring
- Period mentioned
- Only production periods and VINs documented in the application conditions.
- Symptoms
- Poor starting, idle knock or emergency mode.
- Possible cause described
- Implausible signal; possible damaged contacts, earth or sensor.
- Check for the garage
- Diagnose continuity, contacts, earth and sensor; repair only the confirmed cause.
- Cost cited in the source
