1.5 TSI EVO Issue

[SRGTD]

Edit:- remember that the T-Roc was the replacement for the Scirocco!!??

Off topic but yes, I do remember it was the Scirocco replacement, although it’s not an obvious replacement when you look at it; 5 door SUV replacing a 3 door coupe.

As logical as Ford's replacement for the Puma - or was it the Capri!

I defo notice something but I have DSG

it just seems to jump forward every now and again and is low revs normally when I pull off and then let of gas or break.

could also be the DSG have a mind fart thinking I was going to accelerate

I have a model year 19 1.5 tsi 130ps manual on a 68 plate and have the issue.

It is bad when the engine is cold but i have adapted my driving technique basically give it revs and ride the clutch until you are into 2nd, not exactly good for the longevity of the clutch but as they car is a lease then its not really my issue.

its a pain in the backside in start stop traffic even when warm (kangaroo isn’t as noticeable - but its still there) so i would advise a city driver to stay well clear of purchasing one. Not until they get an actual real solution to the problem

I've had my '69 1.5 130 for 3 months now and I thought it was just me not driving properly. Regarding hesitation, seems to be more a throttle map thing than a fuelling thing on mine but it's caught me out a few times.

I've also resorted to riding the clutch into 2nd and give it far more revs than it should need, just for the sake of not bouncing along and looking like a learner!

My 6 week old 130 is nothing but a dream to drive. I thought that coming from an Audi A4 1.4 150 I'd prepare for disappointment especially after reading about all the 'issues' but must say I'm very happy with the way mine drives

I'd expect that MY2020 cars would come out of the factory with the so called fix, but it seems inconsistent!

Is this issue on manuals or do you guys have DSG ?

Mines a 6 speed manual.

Part of me wonders if it’s something as simple as different part manufacturer and one ‘fuel injector’ or ‘fuel pump’ or ‘sensor’ for example isn’t quite tuned the same hence some cars ok and some unaffected...or are all parts from a single source?

 

[RUM4MO]

Some parts will be sourced from more than one parts manufacturer and some parts will be sourced form more than one plant of one manufacturer, it makes no sense for any global manufacturer to single source any parts.

Thought that was likely the case...maybe I’m on to something there then but guess I’ll never know.

Parts come in massive boxes, manufacturers outsource the parts and just take delivery and assemble cars, thats all they are doing, assembling them. Every part on the car is made by a different company seat don’t make parts themselves, one batch of injectors may be from one company, next batch its another, same with almost every part on the car, contracts may also change throughout the production of the car leading to varying suppliers

Leading to differences in fuel supply and kangaroo issues...maybe...

I have worked at a Nissan and Vauxhall plant before so i have seen it in work.

forklift delivers the parts absolute truck loads of them, brand spanking complete engines on pallets. Quite cool to see

I imagine that is a pretty cool sight. I used to love racing the gas forklift against the electric one haha...that was until I ran over my own mobile phone in one

Sadly, I'd think, if that was the root cause of any of this kangarooing then VW Group would have nipped it in the bud early on and been willing to resolve that by swopping parts at the expense of the "faulty/marginal" parts suppliers - no one has mentioned any of that being done, but as owners would you - probably not, but word normally does get out.

I'd think that this kangarooing is down to a major design fault/oversight that is proving a bit tricky to overcome while keeping the emissions in check, one thing to remember it seems, when these cars get homologated for use, they are assigned the correct maximum carbon output - that stated figure and not any other tolerance given in general to that grouping of cars, so the number in the documentation is the one that MOT stations in UK at least, will use and that might cause owners a future problem if "sloppy" tuning/improving maps are applied to these cars - how true that is will remain to be seen.

the 1.5 tsi is a miller cycle engine so not your conventional engine, so that coupled with the ever tightening emissions regs i agree with you that they cannot get a solution that keeps the cars mot legal

I agree, but how could a big company like VW Group end up designing this engine and committing it to production without fully checking it out - that says a bit much for VW Group's engine design commitment.

Edit:- I think that it is officially referred to as being a Budack cycle engine. Officially this technology was only originally implemented into the EA888 2.0TSI engines a bit later in time, but maybe in reality these 1.5TSI EVO engines also ended up with it or trialled it!

Can’t beat a big N/A engine...main reason got my wife a 2.0 N/A and not a 1.0T a year ago...wasn’t expecting issues on a 1.5T to be honest...especially from VW AG.

Never mind.

Nearly drowned my Leon on way home today...weather has been ridiculous.

 

[RUM4MO]

True, but present day emissions regulations have destroyed that being a reality for a new car - unless you buy certain BMW or M-B I think.

Unfortunately so.

If it wasn’t for our company car policy I wouldn’t have changed at the mo to be honest but bound by policies etc.

still...aside from the occasional bouncing the car is great and loving the digital dash and other new tech

Love an n/a motor no sound compared to it, turbo’s are pish
