HI guys. I'm looking to change my current car to something that will be ULEZ compliant. Was looking at Octavia 1.6 TDi or 1.4 TSI automatic.

Which one could you recommend more?

Also do they have issue with carbon build-up?

Hows reliable is DSG gearbox? 

 

Thanks

Welcome.

 

How old are you going, pre 2016 or newer?

?

Do you do trips / cold starts that means a diesel is needed?  Not that it will be more economic really.

 

No issues really with a 1.4 TSI and with a DQ200 DSG.    (Carbon build up is not an issue.)

 

Possible issues with a 1.6 TDI with a DQ200 DSG.  (the DPF for one.)

i do around 11k miles a year. currently owning diesel civic 2012 no dpf issue.

cold starts?

have 10k budget give or take so 2014+

Is the 1.4 a twin charger. ?? I don’t think it is but the cthe and cave engine that was in the Fabias was a bit of an oil burner. If it’s not the twin charged engine then I would defo go for the petrol. Price of fuel and service intervals and smoothness. 
I went from a diesel superb to a petrol 272 and it’s just sooooo smooth in comparison. Mother-in-law has the 150bhp version of the 1.4 yeti and it’s a really nice drive 

No 1.4 Twinchargers other than in Mk2 Fabia vRS. 

To be ULEZ compliant, a diesel has to be to Euro 6 standard which was introduced in Sept 2016 for cars.  11k a year is not much for a diesel engine. Of course, it depends on your style of driving. 

 

I'm running a 1.6 DSG diesel and the two compliment each other. No issues with the DSG.

 

Cars after i think September 2015 diesels are euro 6. May be wrong . Regarding petrol only thing that worries me is carbon build up

Apologies. You're correct. Mis-typed when taking the info from the Transport for London website

DQ200 DSG's 2013-2015 might with some require Service Campaign 34H5 which was started in 2017.

 

Obviously not all DQ200's from 2009-2022/23 have issues, only a small percentage.  Even if 2% you just do not want landed with a bad one.

The premature failure is greater than 2% though, greater than 5% up to maybe 2018. 

Worse with 1.4 TSI Twin Chargers which you do not get in an Octavia.   Not great odds with a 1.6 TDI sadly.

I have a 2014 1.4tsi Superb with the previous gen EA111 direct injection engine - 109kmiles and still runs as well and as economically as when I bought it nearly new. Hopefully that means all is well re carbon thus far.

 

I drove the 1.6tdi version of the same car (both manual) and I thought it was awful in comparison to drive. Sluggish and noisy .

 

Before you decide I'd test drive both versions.

I'd recommend the 1.5t engine within the Octavia with the dsg 7 speed box, as this replaced the 1.4t within the Octavia 3. My 1.5t engine within my experience is excellent on fuel. I've averaged 48 mpg long term with mine on e10, just done a round trip of 160 miles, b roads & town, averaged 52 mpg, ran on 2 cylinders for 35% of the time, not that I'd noticed apart from the dash light to inform me of the fact. Only downside with this engine I have found is that it can run slightly lumpy for the first 2 miles from 0 degrees or lower, only if you are covering this initial mileage around town, until the engine warms up. At any other temperatures It runs sweet as a nut. It's not enough to put me off from buying this engine again, though. The 7 speed dsg box has been 100% smooth, over the 6 months of ownership without any issues at all. 

I've ran diesels for around 6 years within the past (different manufacturer), I certainly wouldn't buy another now, especially one with adblue, diesel seems to be around 20% more expensive at the pumps, too.

There are issues there long term with 1.5 TSI's.  & we have not been long term yet know how they go.

 

There was the early Kangerooing.  That should be sorted, not all are.

They are more complex with ACT, but fingers crossed.  They have a GPF, time will tell.

The Cam Belt and tensioner replacement at 5 years is more expensive than with a 1.4 TSI. 

 

So hopefully newer is better, but that is not always the case. Tried and tested can be better on the wallet.

I don't think it's a problem here - don't think the budget of £10k would be enough for a later 1.5tsi.

It will come time with the early ones that were rejected, never addressed and in the trade and still kangerooing. 

 

Barge poles come to mind.   

 

Be sure to get a good long road test starting from cold, Do not let the sales person warm it up.

Obviously I'm only talking from my own personal experience of owning the 1.5t engine with the dsg 7 speed box. Not trying to speculate on other owners experiences of this engine. 

Within my opinion the positives outway the negatives, only negitive I've experienced so far was slightly lumpy running issues for up to the first two miles from a zero or below cold start. This generally only occurs within speeds 40mph or below. It can be rectified by placing the car in sports mode until it fully warms up, not something I've done on a regular basis. I've always ran my car on E10, I'm awaiting a cold snap to see if using an higher octane petrol would help, too.

I've not had any cold running issues once the outside temperature was above zero degrees, so probably over 90% of the time. 

The 1.5t is the most fuel efficient 4 cylinder 150bhp engine that I've ever owned so far and I've been driving for over 30 years. 

I'd consider either the 1.4t or the 1.5t petrol engine if you had the finances to do so, providing it had a fsh and had relatively low mileage.

It may not help taking the 1.5t for a test drive from cold, as what's the chance of you taking one out below zero degrees. 

Thanks. I willprobly be looking at 80k+ millage tho

@Phoenixboyones that misbehave from cold starts do not need the weather to be as cold as O*oC or lower. 

A chill air temp below 10*oC might well show up poor cold starting and running.

 

But dealers / traders cars can be sitting with fuel that has been in the tanks for weeks or months and that can be pre Winter Petrol & Diesel in the tank from before November.

Many cars run well after they have had a few miles driven and fresh fuel in after being at an auction, moved about occasionally and maybe just had an Italian Tune up to get the cosmetic corrosion off the discs.

I can certainly say I have no issues from a cold start above zero degrees. Even below zero degrees my car is still driveable, never cut out or anything like that. I'm hoping for colder weather so i can try some different fuel. Seems to be running well on Shell e10 at the moment. I always fill from empty. 

Yes cars on forecourts can stay there for months on end, usually running on empty.

Then maybe the 1.4t would be your choice, lower mileage car. I'm relatively new to Skoda, but I'm not disappointed with my Octavia, very much like my dsg box, too. I also prefer the SE spec, not too many tech gizmos I don't want, I can turn my lights on & off when I like. I also prefer the 16" alloys more for practicality, rather than looks. Showing my age😂

@Phoenixboy You have a pretty new car.  You should not have issues, not even the slight ones you do have. 

 

You are only about £2.50 a tank more for Sainsbury Super Unleaded 97 min or Tesco Momentum 99, 

maybe even no more expensive depending where you buy your E10 95 ron.

Cold weather is really not that relevant to if you feel any benefit from using it.

I'm experiencing minor issues I suppose, sign of modern motoring I'm afraid, modern smaller turbo charged engines tuned to their emission limits. Something I can live with, as long as my car stays reliable, I'm happy.

Thanks for the fuel info, my car is happy on e10, but I'll try some of the premium stuff when it gets colder to see if it makes a difference, if not I'll stick with e10, as I'm acheiving good mpg from it & my car usually runs very well. I've not owned a car yet without a minor niggle here or there.
