Intake manifold hose (gofra) replacement

Procedure. The intake manifold hose assembly ("gofra") requires careful removal and measurement before ordering a replacement. Measured diameter is approximately 55mm (verified with calipers). Replacement parts are available on Ozon.¹²³⁴⁵

Difficulty. The job is described as moderately complex but achievable with basic tools; part of the complexity involves working around suspension mounting components near the hose.¹²³⁴⁵

Separate hose — crankcase ventilation hose rupture causing an air leak (2024-07 report). A different hose from the gofra above: a strong air leak was detected with WD-40 spray around the lower area of the intake manifold, near cylinder 4 — engine RPM audibly reacted when the leak point was sprayed. Likely cause: rupture of the crankcase ventilation hose, sourced under article/part 21317 (available on Ozon). Repair requires removing the intake manifold — one mounting bolt is accessible only from underneath, so a lift or service pit is needed. Estimated repair time: 1–1.5 hours. Fix: replace the ruptured cooling/ventilation hose.^6789101112
