VW 1.4 TSI twincharger (EA111) common problems
The 1.4 TSI twincharger is a 1.4-litre four-cylinder petrol from the EA111 family with direct injection, a timing chain, and both a supercharger for low-rev response and a turbocharger for the top end. It arrived in 2006 in the 170PS Golf GT and was made in outputs from about 140PS to 185PS until the single-turbo EA211 engines replaced it in the early 2010s. Besides the cars below, it was used in the Golf Mk6 GT 160PS, Tiguan, Touran, Seat Ibiza Cupra and Skoda Fabia vRS.
Common problems and what to look for on the 1.4 TSI twincharger
The known issues most worth checking when you view a car with this engine. None of them means a car is a bad buy, but they're worth knowing about before you buy, and a good history often shows they've been dealt with.
Timing chain tensioner and chain stretch
What to look for: Ask for the engine to be stone cold and stand at the front while someone starts it. A rattle in the first few seconds before the engine settles is the thing to note. Look in the history for timing chain or tensioner work.
Why it matters: The hydraulic tensioner can fail, often around 60,000 miles, and the chain can elongate, so it runs slack and can jump teeth, which can wreck the engine. Volkswagen paid for many repairs under warranty, and the revised CTHD engine from late 2012 has a stronger tensioner. A car with a renewed chain and tensioner on record has been looked after.
Piston and ring failure
What to look for: Let the engine idle and feel for a steady misfire or shake, and watch for a flashing engine warning light on the drive. Ask about oil use. On a car with any misfire, a compression test by a specialist is the way to be sure.
Why it matters: Pistons and ring lands on these engines can crack, linked to pre-ignition under heavy load at low revs, especially on ordinary 95 octane fuel. The result is lost compression in one cylinder, a misfire and heavy oil use, and it means major engine work. The later CTHD engine got stronger pistons and rings. Owners who used higher-octane fuel reduced the risk, and many engines never have the problem.
Oil consumption
What to look for: Check the dipstick and ask how much oil the car uses between services and how the seller knows. Look for fresh oil at the filler, and on the drive watch for blue smoke when accelerating after idling.
Why it matters: Some engines use a lot of oil, partly because the turbo's seals struggle with pressure imbalances, and worn or cracked piston rings make it worse. Cars with decatted or modified exhausts are more prone. Keeping it topped up protects the engine, and a car with known, steady consumption is a known quantity.

A pre-purchase inspection guide for your car
The CrankSight guide is a pre-purchase inspection (PPI) you do yourself, written for the exact model and generation you're viewing. It walks you round the car on your phone, with every check for that version, engine included: what to look for, where to find it, and what anything you find is likely to cost. As you go it builds an assessment of that car, and if you view more than one, it lines them up side by side.
