Hi all
Been noticing a bit of hesitant engine response lately when accelerating. Doesn't always do it but becoming more often than not.
I have to very lightly put pressure on the accelerator pedal at times to smooth it out.
This also happens with motorway driving where you might be on overrun with your foot off the pedal for a short period, then when reapplied you can feel it.
I know this could be any number of things but is there a common problem that has come to light with these engines of late that might cause this?
Other than this at present its behaving as normal, but i guess something's brewing...
It gets the normal annual servicing schedule at the dealers.

Cheers

How many miles has it done and has it had the spark plugs replaced and the air filter looked at or replaced?

It's a 2019 so if you have a look on this forum you with find issues with other 2019 Fabias.  There was a recent thread with something similar to yours about accelerator if I can remember and find it I'll post a link as I can't remember details or if there was a resolve posted.  2019s IIRC have issues with the throttle body and definite starting the engine on cold days with a member posting a DIY repair to the poor quality fixed electric relay used on the fuseboard.

 

Of course it could be down to another issue, such as lack of full timely maintenance, the annual "service" that Dealerships and most garages do now are little more than an engine oil and engine oil filter change and a look for more chargeable work to increase revenue and profits not even a service of the engine let alone the whole car.

 

Or the issue could be a very simple and basic one.

 

You really need a diagnostic scan tool full report to start the diagnostics now to help speed the process up or much more information and checks to do an over the air website diagnostics but I presume you are not new to VWŠkoda models.  ETA: just remember we've been in threads before.  😁

 

I'll have a quick look for that last thread I mentioned earlier.

ETA:

Sorry I can't find the thread I meant but as you're in some of the threads I've seen you probably know a lot more about this subject and be able to use better search words and terms than me.

 

You could check your engine oil level as per this thread and post for 2018 car. - 

 

 

This thread for throttlebody issue and DIY repair. -

 

 

As always let us know how you get on., good luck.

 

Cheers for the replies.
It's had the annual dealer services like i mentioned.
Spark plugs could probably do with being changed, I'm at 26600 miles now. Just to rule those out. Last service back in August was at 24000 odd. I couldn't see the point of spending an extra £155 on 3 spark plugs at that millage.
Those links are quite concerning regarding the oil leak around the cam belt area due to loose / missing bolts. Seems to be affecting other engine variants as well. I can't remember which my one is. Guess its the EA211.
Not noticed any oil leaks on mine but maybe i should have a closer look now...
No problem with cold starts so far either so i would expect it to be the throttle body issue with the broken internal spring.
Mine fires straight up, fairly newish battery as well so cranks over fast. It also helps now i know how the charging system works so can drive to help that.
 

Simples.

3 spark plugs not 4 and the Dealership should not charge the same price for 3 as 4, but they do.

 

Just do not pay Main Dealership prices if there is an Independent that actually Services cars and not just looks and sees, and often see,s nothing but an Up-Selling opportunity.

 

?

Has the Air Filter been looked at.

Low miles is fine, but 5 years old is 5 years old. 

Ootohere beat me to it again, 3 plugs is 25/33.3% away from 4 plugs so an issue with just one is a third of them and as has been put 5 years is 5 years, some will say the plugs will last years longer and the mileage use is far too low, I do not go along with that, 4 year change seems reasonable to me on such an inexpensive item (car ownership wise).

 

Spark plugs used to be a service item but they're not part of the VWŠkoda (UK?) "service" rather part of the "maintenance" schedule.  At £155, for 3, is up from the £99 for 4 we paid as it was about the same price as buying all the tools and plugs and farting about removing the to me PITA engine air filter box and when I said at least the tools would be an investment for the next change my wife said she didn't expect to have the car then, which I annoyed me as I thought I've suffered all my car mistakes long term. 😆  But the ladies have more common than men.

 

If you are keeping the car you could look at doing the spark plug change yourself it's not difficult or complicated, I could do it so it can't be, and you could look at more expensive different material plugs that last a lot longer.

 

Don't worry about bolts loose but again it's easy to take the belt cover off to have a look (well on the 1.2 it is) and if you don't have a noise or oil loss it might not apply to your engine.

 

I totally agree with about engine numbers then their codes so difficult to know what you have as the number and codes apply to different things on the engine and when looking for parts or information different company want different numbers and codes.

 

Don't assume it's the throttle body, don't assume full stop, diagnosis instead, it might be neither throttle body or spark plugs (or bolts) diagnosis still involves other tools like multimeters, test light, human brain, eyes, ears, nose, touch but with German marque complex computer program cars an appropriate scan tool can often speed up diagnosis greatly and find stuff that other methods might not.  The scan tool has to have a program for your (make) model and year and that program needs to be fully up to date before use to avoid errors, the car battery and if appropriate tool battery, need to be not too low in charge to get a full report, error codes and preferably often live data.

 

As you know the car battery is a hobby horse of mine for various reasons, your car is about 5 years old yet the battery has already been replaced, which isn't uncommon but often unnecessary, so being newish and car starting straight up doesn't mean as very much as you think, even a new battery can be depleted as it's only a store but I don't think it's an issue here by what you have reported but if you are keeping the car as I've probably done before I would recommend you buy and use an appropriate battery charger maintainer given your lower mileage use, or you may prefer to replace the battery again in another 4 years.

 

That's it, all I can think of, unfortunately at a guess I think you could be right that it's probably the throttle body but at that sort of hassle and expense you can't go on assumption and guess you want diagnosis, a scan tool report.  If you don't know anyone with a VW appropriate scan tool you could see if there's a Briskoda member near you that offers such, most for beer tokens, very few others professional with different renumeration. - 

 

HTH.
