Fiveways queues, short Addiscombe trips and a Fiat's weak spots
Fiveways, where the A23 Purley Way meets the A232, is one of the busiest junctions in the borough, and anyone driving a Fiat home from the centre past Fairfield Halls and along Wellesley Road knows the pattern: lights, tram crossings, the Underpass, then another queue. In a Dualogic Fiat, each move is a clutch engagement by the hydraulic unit. Beeping, a flashing gear display or a car that will not select first are the usual first signs of a tired pump, accumulator or clutch.
We do not guess at Dualogic faults. We read the gearbox, check hydraulic pressure and fluid, test the actuator and look at clutch wear, then quote for the actual fault. Sometimes a calibration is all it needs. The fluid matters too, because the wrong type can damage seals, so we fill with the specified hydraulic fluid only. After any clutch or actuator work, the gearbox is calibrated and road tested in traffic, which is where these systems show their faults.
In Addiscombe and the residential streets east of No. 1 Croydon, many Fiats do short trips, and that is where the 1.3 MultiJet diesel struggles. Journeys too short to finish a DPF regeneration leave diesel in the oil, and the car flags an oil change long before the service is due. On higher-mileage examples we also listen for a timing chain rattle on start-up, which can mean the chain has stretched. Catching that early, with correlation fault codes as a clue, avoids the chain jumping a tooth and causing much more serious damage.
Croydon is inside the ULEZ, and most petrol Fiats, including the 1.2 Fire and TwinAir 500s, are compliant. Older 1.3 MultiJet diesels may not be, so check before committing to a big repair. Everything is quoted in writing, and repairs carry a 3-month workmanship warranty. Collection and delivery can be arranged if you would rather skip the Flyover run.
