1.4 TSI (150bhp) Modifications / Improvements

@OccyVRS I wouldn't dare suggest such a thing, but! There was a third element, another box out of shot under the bumper with the exhaust tip attached, which I assumed to be the backbox. When researching res deletes on VAG vehicles they have often looked like the rectangular box at the top of the photo.

  • Depends which aspect of performance you wanted. Better go usually means better stopping is advisable so you could get some better discs and pads; not necessarily bigger but drilled/grooved will stop h

  • The 1.4 4cyl EA211 lump has been in VAG cars for a fair few years - be it ACT, CoD or neither. As far as I'm aware, interaction with the DSG box aside, both variations have the exact same throttle un

  • That K&N filter might not be improving the breathing. So is it an Airbox & Filter kit meant for a 1.4 TSI? They (edit) were hopeless IME on 1.4 TSI Twinchargers at stage 1 or above and 210-220

Hi ,

My 2019 1.5 Tsi has trouble putting 150 bhp down onto the tarmac and that not even flooring the throttle

I have no idea to where all the drivings aids are hiding but from a standstill the performance is not good.

Once the wheels are turning that's another matter.

These little engines produce more power than the original Rover V8 3500 engine.

That is the problem with front wheel drive cars but I am aware that other member will not agree.

That's what 50 years will do. Maybe take a look at the tyres you're running?

My 150ps Leon FR had no issues and even my Octavia, with 350ps, had less drama than expecting - trick differential or not. In the wet is another story, but that's with WOT.

FWD is indeed limiting, but I wouldn't really say that's the case below 200bhp. My vRS can be quite fun in the cold and wet, but that's half the fun.

Hi , thank for your ideas re wheel tramping.

Tyres Michelin Primacy 4+

Tyres on front have 5 mm of tread

If you're running decent tyres then I would probably say it's just one of those things. I remember my Leon struggled a bit below 30mph sometimes.

The XDS (electronic limited diff) I find needs encouragement to do stuff. Off the mark is always going to be an issue. Once moving you need give the steering wheel and go pedal some positive input to get the XDS to wake up. Once woken it definitely helps rotate the car.

If you drive too gently then it doesn't activate and you end up in an awkward mid space where you don't have any help.

Yes, this is also true. XDS isn't really an electronic differential at all - it just uses the ABS to emulate the effect of an LSD.

VAQ is VW's electronically controlled limited slip diff. I always found it a particularly misleading term, as it comprises of Haldex parts and a clutch pack, controlled by electronics, rather than torque sensing mechanical resistance.

Does XDS work? Depends on who you ask. I personally found it useless for acceleration, but it did make some difference in the handling department.

Ultimately, it's a 1.5 Skoda Superb. It's not meant to do standing starts, even if it does only have 150bhp. I loved my Leon FR, and it drove very well for what it was, but it was ultimately a rigid rear beam 1.4 economy hatchback with some big wheels and a flat bottomed steering wheel.

As an aside, I'm surprised you're finding issues with the DSG - I wonder what the manual is like?

I was going to put "fake diff" but didn't want to confuse people. It's a tool for a job and definitely not a patch on a VAQ or a mechanical LSD. I wonder how hard the XDS is working without the user realising? Could be not at all or come be doing stuff seamlessly enough to be hidden. Dunno, so many variables to really make a definitive statement.

I never liked the 1.5. The 1.4 was a much nicer engine.

Agreed. That being said, I wonder how far the average person really pushes things? I would assume XDS is far more utilised in situations with poor traction (wet, ice, etc) rather than 'handling'. Lot's of people throw shade on it, but as you say, it's not really designed to do anything except augment and improve the driving experience of the average person.

A few years ago someone hit the back of my 2016 1.4 Leon FR. I was given a 2021 Golf 1.5 and was very excited to see how the new derivative of the engine performed, since the one in my Leon was so good! To say I was disappointed was an understatement. The whole car was void of any feeling, from the engine to the steering to the clutch. The engine felt rubbish - slow to get going, a lack of low down torque and yet breathless. I will say, I doubt it was any slower or quicker than the Leon, it's just the way it felt. Even the gearbox felt rubbish, despite being the same MQ200. I've never been a fan of these smaller EA211's in cars like the Superb. It moved my Leon along nicely, but when fully loaded things were a bit... sluggish. I'd hate to think how things are in a Superb on the motorway with four people and their bags.

I'm pleased to report though, things might have changed. I had a 2023 Polo as a courtesy car last week, and was pleasantly surprise with just how good the 5 speed box felt. In fact, the whole car felt good - really good! The steering was nice, the engine felt really nippy and aside from a rough 3 pot idle, I couldn't really fault the car. This was a bog base spec, but still had ACC, a tidy digi dash, power fold mirrors (unlike my vRS) and a very pleasant, if plain, interior.

We liked it so much, my girlfriend is looking at one. Mind you, we bough my mum a 2022 1.0 Ibiza FR DSG that I absolutely love, so I might be slightly biased!

Hi ,

Really appreciate the response from members

A generally surefire way to sort axle hop is to do the lower dogbone mount. That said, it does increase NVH.

@OccyVRS This is on my list to do.

I have a billet 034 one you can have for postage. Absolutely ruined my car! I’m looking at Powerflex now.

@OccyVRS That is very kind of you, thank you, but you're not really selling it to me! 😅 I've been considering this one (or a seemingly identical cheaper version from Creations Motorsport): https://progressiveparts.com/product/vagsport-lower-dogbone-insert-mount-mqb-ea888-gen3-gen4-evo?k=112398-2017 I think the Version 1 should my vehicle, as the photo matches up. What do you think?

I would look at a poly version - that is the same billet insert as mine, which wasn't great for NVH. If if was too much for my vRS, I can only image how it would be in a 1.4.

You want something more like this, IMO.

Hi ,

As I have mentioned previously I tried two example of the Skoda Superb Tsi 1.5 , the 2020 car was the series 2 version and had lane assist that I felt a little uncomfortable with.This example was rather flat against the car I have.If I could have found the 2 litre version I would have all things being equal I most probably bought model.

I have no regret of buying the smaller engine example as it drives well and not a single rattle.

I don't drive round thinking I wish I had the bigger engine car.

If you do end up going for this I have one surplus to requirements which you can def have for cheaper than that. Never used (bought the wrong one).

Definitely look underneath and check your mount though. The reason I bought the wrong one was because I assumed badly.
