Hi. 2 months ago i bought Fabia 3 1.2 TSI 90HP. I have a problem because this car doing 0-100 in 13.5s...

I have VCDS, which values i should check to diagnose my problem? I have 0 fault codes in engine when i checked this.

 

Also when im doing full throttle at low gears i have fuel consumption max 40l/100. It should be like 50l/100?

Hi welcome.

 

What is the service, maintenance history of the car, is factory standard or messed about with by previous owners, what year.

 

Often a proper service (not just engine oil & filter change) but for the whole car can transform how well a car goes.

This makes me wonder if your post is just trolling but assuming it is not then this post would be better in the Fabia Mk 2 section (the 3 model number does make things confusing) and if you want specific VCDS info there is also the Diagnostics & VCDS section but some in the Fabia Mk2 will also know.

 

The 'Owner's Manual' is full of useful information to an owner or driver, if you do not have the paper printed copy you can downloads a free pdf version from VWSkoda here. - https://manual.skoda-auto.com/004/en-com/Models

 

I will ask if this thread can be moved to the Fabia Mk2 section.

 

Good luck.

 

Welcome.

So that is 0-100 kph (62 mph) not 100 mph which would be nice.

 

@nta16*No need to have it moved if a Mk3 Fabia from 2015 & not a Mk2 Fabia 3.*

It does sound like it is a Mk2 Fabia 3 Euro 5.

Bottom screenshot shows just what has been posted in the OP.

 

?

What country are you in, and servicing & km covered matter.

?

How many km has the car done.

Is this running 95 ron petrol in where ever you are?

@toot @nta16

 

So i have Skoda Fabia 3 2017r. 1.2 TSI 90hp.

My car doing 0-100kp/h in time 13.5s. (Manual says it should be like 10,5s).

My car mileage today is 290 000km and oil is changeed every 10 000km, petrol 95 and LPG Prins VSI 2.0. But when Im testing accelreation 0-100kp/h im doing this using petrol 95.

 

So what i should to do first to diagnose this car? As i said i have VCDS but there is no fault codes.

 

I also don't undeerstand why I should put this thread to MK2 section while i have MK3 version of Fabia.

 

What the manual says means nothing really.    Is that an after market LPG system?   That was not part of Official Figures from Skoda was it?

 

It is nothing like new / low miles.

That is a lot of oil changing for a car with high km,s covered, why  is that because of running LPG?

(I ran LPG for years and never changed oil more often than necessary like every 6,000 miles.)

 

How often do the spark plugs get changed, or when last were they changed? 

@toot Spark plug changed a year ago. My post is about this how to diagnose a Fabia 3 in vcds bro, i dont neeed advice how often i shoul change oil in TSi car. My car don't have fabric new power 90hp, look at yt videos, this car is doing 0-100kp/h in 11seconds max, mine 13.5.

@teesiskoda 

Maybe take out that spark plugs fitted a year ago and inspect and measure the gap and are they as when fitted.

Yours is not stock though, and LPG is a higher octane than 95 or even 99 ron petrol so if set right it should perform better.

 

So maybe 'bro' give people a clue, have you had the car with the LPG for over a year & have you just recently discovered it,s poor performance.

 

What are there any  is there any fault codes logged, is there misfires? 

@tootbought a car 2 months ago, it has LPG from the start since 2017 its Prins VSI 2.0 called. As i said earlier, any fault codes in vcds.

I read you said there were no fault codes.

 

So there is a record of spark plugs replaced a year ago, but that means nothing, inspect them.

 

You might just have bought a quite high km / mileage car(180,000 miles) with not much oomph.

@toot

 

ok, so i wlll check those spark plugs. Could you tell me what to pay attention to when I take them out?

Sorry my mistake, as you called it a Fabia 3, and not Mk3, and without a year of production I wrongly thought you had a Fabia 3 (trim) Mk2.

 

Back to your concern, your car has 290,00 km (180,000 miles) in 5-6 years, not factory standard, you have only owned the car two months, you are told the oil was changed every 10,000 km and spark plugs last year, you are doing "full throttle at low gears" and worried about higher fuel consumption with no engine error codes showing.

 

There is more to the car's fuel consumption and acceleration than just the engine or lack of engine error codes.

 

You need to look at and record live data to see how the engine and rest of car is performing - but you have a non-standard car with 180,000 km on it so do not expect it to preform as a newer car being thrashed.  One element of 0-100 times is the driver and how much he is prepared to thrash the car to get the lowest time.

 

Accelerating hard and expecting good fuel economy makes me wonder again about whether this is just a joke or just a misunderstanding as English is not your first language.

 

You can not get the best out of any computer programing unless the (whole) car is in a good or at least reasonable service and use condition, the VCDS and car's computer programs can not defy mechanics and physics but by all means if you want to ask on the VCDS section I mentioned earlier.

I just missed this with my last post - you are now getting a better idea.

 

Your @toot should allow you a drop menu with @toot on it.

 

As you have only had had the car 2 months do you actually know if the car had 10,000 km oil (and filter?) changes, that is 29(!) changes, do you have proof, not that it matters now unless that was part of your purchasing contract.  Plugs I leave with toot.

ETA: wrong number of oil changes

It is likely just gubbed and the previous owner got their moneys worth out of it.

 

My engines to run on LPG just ran on lpg & were built to, with no need to start on petrol and had no petrol tanks.

A number of years back a mate had a petrol V8 engine from them and wasn't over impressed with the product or them, might just have been a one-off or they just didn't get on but I know from bitter personal experience (not of them) more than once that a good reputation takes longer to lose than a bad reputation.

 

@toot whilst it's just the two of us here - would this petrol/lpg Fabia Mk3 have different to factory plugs fitted?

 

It might well have, and the OP should be checking this and with a Qualified LPG installer.

LPG plugs for LPG only then(?).

Standard Platinum are probably fine, as will be Iridium with these engines and LPG, but i do not know it was old school V6 or V8,s i had and good ignition leads were very important.

Does LPG burn hotter than petrol, as if so wouldn’t the sparks need to go up a temperature band?

 

Dont know enough about LPG but different gaps?

 

I mean the basic obvious thing is to check they’re lightly coated rather than black or discoloured.

 

I would also ask if the ignition system HT, coil packs and sparks are I. Good Nick.

 

I assume the air filter gas kit been left for 60k and is clean?

I can't remember anything about LPG as it was so long ago that it had a very slight interest from car drivers over here but toot and I are big fans of air filters and housing being clean, at 180, 000 miles it should be on its third or fourth air filter at least - but that's just engine stuff, the rest of the car is 180,000 miles (290,000 km) too.

 

When did this 0-62 mph test become a thing with secondhand cars, a sports or speed modified version perhaps but for others(?), can you pull off in 2nd to save a second (if not the clutch).

@nta16You completely misunderstood me. I meant that the car burns fuel at full gas in my opinion not enough because it shows me 40 liters and there should be like 50 liters of temporary combustion at full gas in the first gear. Too little fuel, therefore, can be related to poorer acceleration.

 

That's what I meant from the beginning, so I don't know what you mean with this expectation of low fuel consumption by me xd

Have the system serviced by a LPG engineer who understands the system and the change from petrol to lpg.

My systems / vehicles got about 3 miles to the litre of LPG / Autogas.

That was much better than they would do on petrol if ever to be run on petrol.

 

People with some vehicles on LPG can use many more litres of LPG compared to petrol but were or are getting LPG at half the price.

I was getting LPG at half the price per litre or even less than petrol when running LPG.   (& did not need a Tachograph when towing for Gain or Reward, but was not allowed another fuel source.)

Yes sorry I was confused and thought you had just missed putting the decimal point - but you had forgotten to mention that you were on LPG.

And other things, for that, with petrol,  I would look at live data of fuel trim, short and long and record, from the dispensing fuel pump, the actual amount of petrol added back from a full car tank (first end click of dispensing fuel pump) to full car tank (first click) again and the mileage covered to calculate the overall miles per gallon (l/100km) as a check or conformation of any computer figures I got from any machine.  The cause of any consumption may not always be rectified with a VCDS but you can get a lot of information from them to interpret.

 

I have never used LPG or VCDS so can be of very little (or none) help with those.

 

Your initial post and site nameplate gives very little information, if you had just been given the answer to only which boxes to look at on the VCDS would you have started with checking the spark plugs or toot's good advice in the last post.  This is not Twitter or Facebook or other sites where a very quick but complicated question with very little information will begiven a very very quick answer that's wrong.  You asked how to diagnose the problem, if you only want to do that using VCDS then Ross-Tech have a forum. -https://forums.ross-tech.com/index.php but you are very welcome here, I will butt out and leave you with toot and others.
