Hi Folks. I'm new to this forum I have Rapid 2015 spaceback 1.2 Tsi manual.

And i noticed hesitation from the engine on harder acceleration, usually away from junctions in second gear? like it takes some time to get acelleration and stalls for a second.

Is this normal for this engine? I bought it a month ago. 

 

Whats the Optimal RPM range or speed for manual transmission of this car?

I use to put it in second gear when moving slow thrue junctions. Do i have to adapt driving stile, put it in first gear when moving in junctions?

Its dangerous when car doesnt move quick from second gear and you are in the midle of the road ...

 

any help  would be appreciated.

 

 

 

 

 

I found the older 1.2TSi (8V chain drive) did behave that way too with a bit of a flat spot in the mid range - but only at certain throttle openings. Light throttle or pedal to the floor it wasn't noticeable. Some on VAG forums say it has no boost in first gear, so that would be a worse choice for T junctions.

 

I haven't driven the newer 1.2TSi (16V belt drive) enough to recall if it behaved similarly - but I did find the low-rev drone on that one a step back from its beautifully refined predecessor.

 

The engines changed over in the Rapid in mid 2015 so you could have either.

 

The rev range on the 8V is remarkable. It really has loads of useable torque. I now drive a 1.0TSi which is the exact opposite

This really...

 

"I use to put it in second gear when moving slow thrue junctions. Do i have to adapt driving stile, put it in first gear when moving in junctions?"

 

I have occasionally found it slow to pick up if you catch it wrong and want power for a quicker getaway say at a junction/island in 2nd gear. If I know I need a swift move off and I'm almost staionary I stick it in 1st. BTW I have the 1.2 TSi 105 engine in my '14' plate Toledo, the same as it's Rapid counterpart.

It's a matter of working out how the engine behaves in different situations - if you catch it wrong then it's underpants to brown as you find yourself half way out of a junction with no power, then the turbo kicks in and away you go.

 

The 1.2 had no turbo in first so it could be scary at a busy motorway sized roundabout trying to pull away only to find out there was no power until you got it quickly into second.

 

If you take your foot off the gas and then back on then it be a few seconds before the turbo kicks back in so you have to factor this into your driving style.

 

Once you get used to it the car can be good fun to drive and I've surprised (scared? 😁 ) a few people with what it can do - both the 1.2 I used to have and my current 1.0

Thank you guys so i guess this is normal with 1.2TSI 90 KW engine i didnt know... I guess i have to adapt to knew car   

Do any of you have sugestions how to move in junctions  with this kind of engine so i dont  "damage it" in a long run. I guess my question is what is the best way to drive this engine to get the most out of it.

For the moving off whether you need 1st or 2nd it's something that needs practice. I came from the 1ltr Citigo to this car so I already knew it may lack a bit of go at a very slow speed in 2nd and I'm in 6th gear by the time I reach 45mph. It's a bit of a chalk and cheese situation too as I have a Mazda 2ltr  engined (MX-5) totally different drive and the way I use the gears.

Yes my 1.2tsi Roomster behaves this way especially if in second gear on an approach to a roundabout with engine rpm under 1500 rpm. On booting it there is nothing there until 1500 rpm when the turbo kicks in. I have resorted to dropping to first gear to avoid the missed heart beat moment when you realise that it will be difficult to accelerate out of trouble. There is no turbo boost in 1st gear otherwise the engine will over rev. My handbook does say to change up to 2nd gear within the cars length to gain the turbo kick but this doesn't help when you are on the move.

90kw? Actually unofficial Dyno testing did show some 1.2 had near that, but it was rated at only 77kw by VW. No wonder you think it's slow if you were expecting 90kw.

Nail it in first - works fine and provided you keep the oil changed on a regular basis it won't hurt it unless engine is cold
