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.
Cost cited in the source: No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.

Engines: 1.4 / 1.7 SDI-TDI (Diesel)

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.
