Hi all,

 

I have a 2016 1.2tsi Yeti, engine sounds fine on startup/idle and when revving in neutral, under light acceleration the engine is a bit clattery/tapperty (not great explanations!)

 

Under a firmer foot on acceleration it’s fine, is this normal. Only noticed lately due to hot weather and windows down.

 

Any help appreciated.

 

Thanks all.

You don't say how many miles covered, or when serviced.

 

Best thing you can do if the car is without any fault and runs fine other than the noise is have Fixed Servicing with a TSI.

Maybe go with 5w 40 FS Oil / VW 502 00 rather than 5w 30 FS LL / VW 504 /507.

If you are concerned have the Fault Codes checked, see no misfire codes logged or any others.

Be sure to have Spark Plugs replaced at the Service Schedule / Guidelines or sooner.

It’s done 16000 miles, service due in September.

 

 

Its probably OK, the tsi high pressure fuel pump can sound a bit tappety  from outside the car and with the windows down, under stronger acceleration the engine noise will drown it out, however....

 

Its under warranty so take it to your dealer and ask for a master tech to check it out. Not a receptionist, service manager, executive or whoever, but a master tech. Then get your concern registered on the Skoda system. This is the difficult bit, nag them and demand some proof. If they refuse then write a letter to the dealer principal, cc it to the service manager and warranty claims managers, detailing your concern, your visit and comments made and your desire to log the concern in the Skoda service/warranty system. Ask for written reply.

 

That way if the engine goes tits up you can tell Skoda UK you told them it had a problem which you reported within warranty.

Do you run the car on 95 RON, supermarket fuel?

If it has done the 16,000 miles on the Oil that it left the factory with in 2016 then there might be the reason for sounding tappety in the recent weather where last summer it maybe did not.

The oil might be Long Life and good according to the Oil Company and VW Group for 18-20,000 miles,  but Long Life Oil can mean short lived TSI's.

 

As to the 95 ron petrol, supermarket or not, that is the fuel they are designed to run on, but then they might run better on 97 or 99 ron, 

not that it matters if it comes from a Filling Station with a Supermarket Name or some Branded National Fuel Retailer.

I ask as my vRS (whish was admittedly the older TFSI) sounded like a bag of spanners inside a Ducati engine when I was being cheap and running it on 95 RON.  Almost sounding like it wanted to stall at low speeds.  A tank and a bit of VPower later and all was well.  I think the TFSI engines were problematic with soot deposits around the injector nozzles and VPower had detergents which cleaned them up somewhat. 

 

Not sure if the 1.2 TSI is the same but from what I've read and seen on here these things like the higher octane stuff.   Yes they run on the 95 but run a little smoother with slightly better MPG on the higher octane stuff. 

 

With no lab tests to back me up, I'm 100% convinced Tesco Momentum is the best fuel for mine so that's all I use now.

That was my first thought, too.  Fill up with higher octane stuff and see if the noise goes away.

penguin17,   

VW will tell owners of engines like yours & others that Super Unleaded 98 ron is better for lower emissions and efficiency so only 97 or 99 ron in the UK available and perfect.

They say GTI's / R's, but that will be vRS / Cupras as well.

 

It is going to do no harm and more likely good with all TSI's but VW or Skoda are not putting that in clear terms to owners.

'is fine'   So not that big an up on that then....

Just use Sainsbury’s normal fuel.

 

It had its first service which included oil change last September at 8500 miles and the oil used was long Life I believe.

OK, thats not so bad then, i was more concerned you were on Variable Servicing.   

Maybe buy the 97 Super at Sainsbury next time, worth the 5 pence a litre extra. Worth trying for the extra £2.50 or so a tank fill.

 

Maybe think on getting 5w 40 FS oil in at the next service.

If the Service Desk Staff says you can not, that is because they often say that. Ask them to ask the Master Tech and ask them if they have VW 502 / 5w 40 FS in the Dealership or you can buy and bring in if they only have Quantum 5w 30 FS LL or other oil to VW 504 / 507.

My 1.4 TSi has always sounded "tappety" above 2000 RPM for the first few hundred yards when the engine is cold, and is fine thereafter.  It's only noticeable with the windows down when driving between hedges or walls. The noise is proportional to engine speed AND to the amount of throttle applied, so not purely mechanical. The noise is no different after its annual oil change. I run on BP Ultimate (slightly better MPG / slightly smoother).  I wondered whether it was a tiny leak from a flexible joint in the exhaust system, which cures itelf when the pipe warms up, or possibly a noise due to greater piston to bore clearance when cold.  After 45000 miles during which time the noise has neither increased or decreased I'm not too concerned.

oil change interval

Yep, like you most noticeable between hedges, walls, parked cars as the sound is enclosed.

 

Strangely with the aircon off it’s less noisy!

 

A few people have listened and just say it sounds like an engine! Will bring it up when it goes for its service though.
