• Engine guide VW 1.5 TSI and eTSI (EA211 evo) petrol: problems, costs and what to check

  Cold-start judder, oil use, coolant leaks and 48 V faults are the risks, so buy a late car with software and service records and check the oil and coolant.

  Dry DSG with a known weak mechatronic and clutch. Buy only with recall and oil-change records and a clean pump test.

Known issues for this car

Before you buy this car

From the generation guide

1. Check the coolant level and look for leaks at the water pump and thermostat housing. Bad result: low coolant or a leak.
2. On a 7-speed dry S tronic, test pull-away from a stop and in traffic. Bad result: judder or jerks. Ask for clutch history.
3. Look at the rear discs and backing plates for rust, and ask about brake wear at the last inspection. Bad result: heavy rust or worn brakes.
4. Test the infotainment system on the test drive and ask whether the software update was done. Bad result: faults that return after the update.
5. Check by VIN that the front seat belt recall was done. Bad result: the campaign is still open.

From the engine guide

1. Oil use (no scanner). Check the dipstick and top-up history. Bad: low level, blue smoke, or ring work without an invoice.
2. ACT and camshaft (scanner). Listen for a shudder when the engine switches from two to four cylinders, and read faults. Bad: constant shudder, EPC light, or camshaft codes.
3. Coolant (no scanner). Check the level cold; look for white residue or a sweet smell near the thermostat module. Bad: low level, stains, weak cabin heat.
4. Particulate filter (scanner). On a short-trip car, read soot load and GPF codes. Bad: GPF lamp or regeneration faults.
5. Cold start (scanner). Start stone cold; pull away in 1st and 2nd. Bad: judder between 1,200 and 1,800 rpm. Ask for the update record; a scanner shows the ECU version.
6. Recall check. Enter the VIN in the official recall check. Bad: an open 24ER, 24EV or 24EP campaign.

From the gearbox guide

1. Fault scan (needs a scanner). P17BF, P189C, P1895 or P0841 mean a pressure fault, usually the accumulator housing. Get a repair price or walk away.
2. Pump test. Ignition on, engine off. The pump should run briefly and stop. A pump that keeps whirring points to the accumulator.
3. Oil. Look at the gearbox and the undertray. Wet oil can mean a mechatronic job.
4. Control unit signs. Ask about a flashing gear display, a blown gearbox fuse, or the car losing drive at a stop.
5. Clutch values (needs a scanner). Read remaining clutch travel and the adaptation counters. Counters that will not adapt, or very low travel, mean a clutch job soon.
6. Road test in 6th and 7th. Full throttle from 1,000 and 1,500 rpm. Engine speed that swings by up to 200 rpm means a worn clutch. Also feel for judder pulling away.
7. Reverse, cold and warm. A flashing R, no reverse or a crunch is bad.
8. Cold start. A rattle for 5 to 10 minutes, or in 2nd on overrun, points to the flywheel.
9. Paperwork. VIN check for open recalls; for 2008 to 2013 cars, proof of the 2013 oil change; invoices for any mechatronic repair.
