2 known faults with sources
PD TDI camshaft, injectors and cylinder headInjection / cylinder head
- Engine / equipment
- 1.2, 1.4, 1.9 and 2.0 TDI unit-injector (PD) engines, including the VW-sourced 2.0 CRD in Chrysler, Dodge and Jeep
- Period mentioned
- 2000–2010
- Symptoms
- Growing noise from the cylinder head, power loss and rough running (cams and lifters); unstable idle, smoke or hesitation (injectors); on the 16-valve 2.0 TDI, coolant loss with no visible leak from a cracked head.
- Possible cause described
- The camshaft also drives the unit injectors and carries a heavy load: without VW 505.01 oil the lobes and lifters wear. 2.0 TDI PD injectors fail frequently. Some 16-valve 2.0 TDI heads (part number ending in A) crack; VW considered it fixed by the end of 2006.
- Check for the garage
- Check the oil history (VW 505.01), listen to the head, check injector balance rates with a diagnostic tool and, on the 16-valve 2.0 TDI, read the head part number (03G 103 351) and look for coolant loss.
- Cost cited in the source
- Camshaft and lifters: approx. €400–800; 2.0 TDI PD injectors: €900–2,000A rough figure from the original database, not an up-to-date quote.
Mileage cited in the database: 120,000–200,000 km. This is not a maintenance interval and does not predict a failure.

Automatic gearbox in the cold and brake-servo vacuum pipe on the SEAT ArosaKnown weak points
- Engine / equipment
- SEAT Arosa (twin of the Volkswagen Lupo)
- Period mentioned
- 1997–2004
- Symptoms
- On the 1.4 automatic, a loud noise when shifting from 1st to 2nd in cold weather; cracks in the brake-servo vacuum pipe that can remove brake assistance (1998–1999 cars).
- Possible cause described
- SEAT acknowledged the cold-weather automatic fault and replaced parts free. Recall (2002) of about 120,000 Polo, Lupo and Arosa from 1998–1999 for the vacuum pipe.
- Check for the garage
- Test the automatic gearbox from cold; check the campaign by VIN.
