Despite being a quality model, it would be a mistake to be complacent when buying an Eos with missing history or obvious running problems.
A common issue on FSI engines is worn cam followers for the high-pressure fuel pump. If a car cuts out for no reason, or the engine check light is illuminated, it could be on its way out. If it does fail, the damage it causes can be expensive to remedy. A receipt showing that the cam follower and seal has been replaced will offer peace of mind.
The 1.4 TSI had a timing chain and it can stretch and rattle if it’s not been treated to fresh, quality oil, so listen for early signs of this when you start the engine from cold. More worryingly, piston failure has also been noted on this engine, so don’t get caught out.
It’s known for T-FSI engines to develop coil pack issues, so if a car misfires or hesitates while you’re driving, this could be the reason why.
The diesel engines in the range are reliable, but if you notice a distinct lack of power or, worse, it goes into ‘limphome’ mode on a motorway, it could well be suffering from a clogged variable
vane turbo. The 2006-2009 Siemens Piezo injector engines, as fitted to the 2.0 TDI, aren’t particularly reliable and there was a manufacturer recall in 2012. Make sure any work has been done by quoting the car’s registration at a VW main dealer. Lift pumps can also let go, so any Eos that doesn’t run perfectly should be viewed with suspicion.
Also, beware of a glowing diesel particulate filter (DPF) dashboard light. Being something of a weekend plaything, Eos owners may not always give their cars the opportunity to perform a proper regeneration.
Generally speaking, the post-2009 common-rail 2.0 diesel is much better, largely trouble-free and very smooth.
Bear in mind that the PD engines require oil that meets VAG specifications: 505.01 (fixed servicing) or 507.00 (variable). Search through receipts to ensure this has been used otherwise the car might have suffered camshaft wear. A good sign of a fastidious previous owner will be if they’ve changed the oil and filter every 7000 miles and used a long-life brew.
Gearboxes, including the DSG, should prove bulletproof, but the DSG requires an oil service every 40,000 miles. If you identify any problems on a testdrive – such as strange noises or lazy gearchanges – walk away. A rattle or excessive vibration from the transmission on manual cars points to a worn dual mass flywheel (DMF). It will cost £500-£800 if you get an independent to replace it, so beware.
The common rail EA 189 2.0-litre TDI was at the centre of Volkswagen’s emissions scandal and a recall was issued in early 2016 to have the necessary software update carried out. Initially rumours abound that the recall work blunted performance, made the cars noisier and hurt economy. However, Eos owners who had had the work done reported on the Eos Club forum (vweosclub.com) that performance was largely unaffected and MPG was actually a little better. You can check whether the car you are looking at was one of those affected by logging onto Volkswagen’s website
(volkswagen.co.uk) and determine whether it actually had the work done by contacting a VW main dealer and quoting the car’s registration number.
