It’s still in warranty? I’d be straight back to VW and harassing them to look into it.

For what it’s worth, I took my car to VW over a squeaky pedal.

I’ve also known people to have warranty work to replace worn gearknobs.

Take it back to them for investigation. Get them to check your timing chain and tensioners while they are head first in your engine bay.

Unsure if I am honest.

Take your car to a VW workshop asap to check if your car is subject to the recall action for the variable timing gear.
Many exemplars of 1.2 TSI EA211 belt driven engines of 2014-2015 production mount a defective variable timing gear which causes the rattle at cold start-up and could also potentially make the engine go out of timing and destroy itself.

If you search on YouTube for «start-up rattle 1.2 TSI EA211 or 1.6 MPI EA211» you can find many videos of the rattle sound.

I agree with you entirely, modern engines could and should be built to sound smooth, most manufacturers can achieve that — so why can’t VWG do it?

I’m not sure if it was on this forum or another VWG marque forum — ie Skoda or SEAT, but someone posted describing these engines as sounding like a sewing machine, now in the past, if someone described the sound their engine made was «like a sewing machine» they would have meant it was so smooth running. Now, when that term is used, it refers to all the silly noises that these engines make — is that progress, does a «bomb proof» extended warranty negate the need to supply properly designed engines and other major parts? I don’t think so.

Edit:- I remember the point in my motoring «career» when I finally discovered that Ford had started producing engines that would end up in the bin at lowish mileages, maybe they have improved as VWG have slid down a very steep slippery slope.

Thought I’d join to give an update despite not even having a Polo. my experience is eerily similar with a 2014 Seat Leon 1.2 TSI at 55000 km, which is 34375 miles to you. Thanks to info on this forum, it seems it has an early belt drive EA211. This is a brilliant motor, perfectly capable of pulling a 1250kg car, even as a fully laden station wagon. This is a Czech car imported into Germany, but ultimately that is irrelevant, the engines are all made in the same place.

As far as I can tell, Seat has no knowledge of any of the recalls mentioned here.

The engine has always sounded tappetty at idle, but in fact that is probably the injectors. On startup it sounds like it hasn’t run for six months, until some oil gets into the tappet covers. You get used to it, but you need to pay attention if it changes!

Recently it got louder. It was most noticeable at idle, and there was occasionally a soft knocking at low speeds audible even from inside the car. It wasn’t consistent. Then on the EPC lamp came on. Then it went off. The Start-Stop switched itself off. I assumed the knocking sound was the injectors on a default ‘distress’ mapping. Boy, was I wrong.

The EPC light was now on permanently but there was no noticeable loss of power and no change in fuel consumption. The next day I drove it in to a main dealer who told me in no uncertain terms I was close to a terminal engine failure. They replaced the inlet cam variable timing actuator and the cam belt. They told me they had never seen this fault before. Seat paid for the valve work and parts after the dealer hassled them twice. Which was nice.

I surmise that the actuator, or its bolts, was working loose or was falling apart. As described vividly elsewhere, that could lead to a situation where the cam just stops, which could mean new pistons, valves, and head.

So, if you hear strange noises from the top of your EA211, get it looked at, and preferably by a Seat dealer!

Good advice, yes all these engines seem to have been built in a Czech Skoda engine plant.

I carry out all my own car servicing now that my wife’s 2015 Polo 1.2TSI 110PS is outside its warranty period, and I make a habit of removing the top cover from the cambelt area of the engine, checking mainly for evidence of oil escaping as well as making sure the variable timing pulley on the inlet side’s securing bolts «look okay».

I believe that some oil will start to escape before the pulley is loose enough to cause trouble — but I think and hope that these problems only affected very early build EA211 engines.

Just a pity that VW Group were not honest enough to check all cars within that early engine build range either at point of sale or, early recall or the first time they appeared for workshop servicing, this could have been caught before things went bad — but time and again VW Group has proved that it is not fit to be viewed as a Germanic manufacturer — or German’s quality and integrity standards have dropped into the gutter and it is living on its past good name, which is a pity as Germany like UK used to get trusted when it comes to designing and building credible products.
