Re: 1.5 EVO - 1st gear kangaroo

Post by NGr » Fri Jul 02, 2021 8:42 am

I have a MY21, 1.5 manual. If I start the car and drive, it lurches in 1st and second gear until it has warmed up a bit.

I have found that no matter what the ambient temperature after starting the engine it idles at ~1400 rpm for a while, then drops to ~1200 rpm before dropping to what I would consider a normal idle of ~800 rpm - it takes about 1 minute to drop to this normal idle. If I wait for the revs to settle to 800 rpm the car drives fine.

I've never had a car behave this way before and I shouldn't have to sit idling until the car is drivable. My wife has a Citigo and that drives fine even when running on the "choke", I assume that the mapping is different in the T-ROC (to heat the cat up as quickly as possible) to meet the ridiculously strict emissions standards from the EU.

Yeah that sounds like the kangaroo alright.
Even the latest 1.5's have it 🤷‍♂️🙈

If they messed with the fuel/air mixture ratios, then there will be different mappings covering a mix of ambient air temperatures vs engine temperature. So a 'cold' start on a warm afternoon needs different mixture from a 'cold' start on a frosty winter morning. Obviously there needs to be some balance between the extremes and it could be that fixing a problem at one end of the spectrum makes matters worse at the other end.

Just when I was beginning to think that a 1.5tsi may be safe to buy now, this appears to show that VW have not cured the 'Roo. Never mind, quite like our 1.0 for what we use it for.

Took my car to be serviced and asked them to look at this problem as well for me, hopefully they tell me something other than "it's fine"

Picked up my 1.5 tsi Dsg in early may and been actively looking for the roo defect.
But it’s been faultless hot or cold so far.

VW said it hasn't found anything, I'm thinking whether its how I use the clutch, I have a bit of a heavy foot. had a polo 2001 model and its clutch was pretty light when so I used to almost release it before I press the gas. It might just be muscle memory, will be getting it back from the service hopefully today.

VW are reinstalling the ECU software for it, so I will find out.

My new (June 2021) T-Roc 1.5 EVO Black Edition can be a little difficult to pull away in smoothly when warming up. It's nothing major, I've adjusted my driving style to compensate.

A few people have had the software update and it made no difference, myself included.

The kangaroo gives you a similar impression of when we were first learning to drive. 🤷‍♂️

Turns out it is my stupid foot, I had a Polo from 2001 and it was a bit of a late clutch so my muscle memory needs to adapt from it.
