- Engine guide VW 2.0 TDI (EA288) diesel: problems, costs and what to check
Coolant leaks, EGR and AdBlue faults are the main risks. Buy with a cold-start check, a coolant pressure test and a full scan.
- Gearbox guide Audi DL382 7-speed S tronic (0CK): problems, costs and what to check
A smooth gearbox when serviced, but mechatronic and clutch bills are large, so buy only with a scan and oil records.

Before you buy this car
From the engine guide
- Turbo (needs a scanner). Read boost faults and check the vanes. Bad: power loss, whistle or smoke.
- DPF (needs a scanner). Read soot and ash loading. Bad: frequent regeneration or high oil level.
- Intake manifold (pressure test). Pressure-test the cooling system. Bad: coolant loss with no puddle, worse under load.
- EGR cooler (pressure test). Cap the cooler hoses and repeat the test. Bad: it holds only with the cooler bypassed.
- AdBlue and NOx (needs a scanner). Read NOx sensor and dosing faults. Bad: an emissions warning, a restart countdown or crystallised AdBlue.
- Water pump and heater. Start cold; heater must blow hot. Bad: weak heat, wandering gauge, dried coolant.
- Oil pump drive (needs a scanner). Listen for a rattle at idle and check for oil-pressure codes. Bad: a red oil-pressure warning.
- Belt and pump invoices. Ask for dated belt, pump and thermostat invoices. No record means budget for a belt job.
- Recall check. Enter the VIN in the official recall check. Bad: an open 23Z7 campaign on a T6.
From the gearbox guide
- Mechatronic scan (needs a scanner). Read the gearbox fault memory for P0718, P0811, P0607, P179B and P17D1. Bad result: stored faults or a recent limp mode.
- Cold clutch test. Pull away uphill and reverse up a ramp, twice. Judder means clutch work.
- Pump motor history (needs a scanner). Check for pump and circuit board faults. A failed motor can stop the car.
- Speed sensor campaign. Ask a dealer for campaigns 34 22 54 and 34 23 62. Scan for P0718 and P2768.
- Gear position sensor (needs a scanner). On cars up to 2018, check the key comes out in P and the display lights.
- Oil leaks. Check the plastic pan, mechatronic and housing joint.
- Oil records. Look for 60,000 km oil changes with G 055 529 A2. Stamps prove nothing.
