Buy-risk rundown
| Issue | Symptom | How to check | Typical cost (as of Nov 2026) |
|---|---|---|---|
| Mk5 HPFP cam follower / high-pressure fuel pump | Metallic tick; worst case cam lobe destruction | Inspect follower at every major service; ask for photos | Shop cam-follower/HPFP work often ~$500 class parts+labor [1] |
| Mk5 timing belt (interference) | None until failure | Demand dated invoice | Cost not yet verified on this page [2] |
| Mk6 timing-chain tensioner (early cars) | Cold-start rattle that does not clear — stop driving | Confirm revised tensioner; listen cold | Failure can destroy the engine; repair cost not yet verified [3][4] |
| DSG fluid neglect | Shudder, jerky shifts, limp mode | Confirm ~40k mi fluid/filter service | Service is preventive; mechatronic repairs cost more — not yet verified [3] |
| Carbon buildup (direct injection) | Rough idle, misfires | Walnut blast history | Not yet verified as a shop price on this page |

- Manual cars skip DSG risk; still verify clutch health.
