Before the comments like; “Learn to drive mate!†I would be interested to find out if other 140 BHP owners have had to retrain their left foot how to operate the clutch?

When I started out, I tended to stall the SM at least once a day. This would be when slowing down in 2nd gear, and then the road situation would change, and would accelerate to find the engine had stalled. It’s almost like the vehicle is expecting the driver to change down to 1st. :|

I test drove the 140bhp diesel - and kept stalling it! Did it must have been 3 times in 10 minutes - when picking up the clutch at slow speeds in 2nd.

The VAG Diesels are not forgiving if you get the rpm below the idle speed. The PD's were worse than the CR, which seem to have a little more leeway then the PD's. My 140 Octy PD 2.0 was very dramatic - the CR 170 allows something like 800 rpm and then quits -but not as dramatically.

Problem is that with all the torque available down there, one tends to get a little sloppy.

That does not sound right. If you were stalling from a standstill one mights say it is just getting used to the clutch but as you describe more of a fuelling problem I would have thought. I would take it back to the dealer.

I think the engine is designed to cut out at about 800rpm. A traditional stall in a PD engine is a violent affair, indeed its not unknown for a stall to tear the gearbox off its mounts! I guess something is built into the software not to give a soft-stall if the revs get too low.

It does not feel like a fault, more like an unforgiving set up. As Agerbundsen said; "Problem is that with all the torque available down there, one tends to get a little sloppy". I was just interested to see if other owners had found the same.

Remember also a new engine is not as loose as a fully run in one.

Thats a good point

Stalled mine twice; first time being the unrequested 180° reverse manoeuvre going down hill in the snow, in first gear with hill decent engaged and the other trying to accelerate away having slowed right down but forgot to drop the gears

As commented above much less violent than the 140 PD, which happen a couple of times for the same forgetting what gear I was in :

I managed to stall the 140 on the test drive - again, let the revs drop a bit low.

Did the same - stalled it - on a 140 at the test drive.

Not so much due to letting the revs drop - but more like not realising just how tight the new clutch was.

i.e. you had to put the pedal right down and it started to bite only a few cms from relasing the clutch pedal.

Got a bit lazy I guess, since the previous car ( Mazda) that I drove for 5 years or so had a clutch that was completely the opposite.

I'm sure it's just a case of you and the yeti getting to know each other....

I stalled mine once on the first day and it seemed pretty violent. Thought something had gone seriously wrong, but thankfully tried a restart before calling the dealer!

I've managed okay so far with the CR170, but the joys I had when I first had the PD130 in the Fabia vRS - especially having just done 45k miles in a clutc pedaless smart....

I haven't noticed it on the SM as the thing is so quiet but the PD130 appeared to switch the fuel off (engine noise went completely) on the over run, ie under engine braking.

Most cars have an "anti-knock" sensor to avoid damage, perhaps the Yetis is a little aggressive.

Most cars have an "anti-knock" sensor to avoid damage, perhaps the Yetis is a little aggressive.

The "knock" in a petrol engine is the normal ignition for a diesel engine - so antiknock is not relevant to diesel engines. Probably it is more an injection control difficulty at low rpm that the ecu will not permit.

I wonder, if while on the over run, the fuel is leaned down to the absolute minimum due to the attainment of low emissions and fuel consumption. Then at low engine revolutions,when the accelerator is suddenly pressed, the loading it too much for the engine, so it stalls suddenly. This does not happen at higher revolutions because of the higher torque and inertia of the rotating masses within the engine. This is why I think that it might be a fuelling problem, one that should easily be overcome by reprogramme at the dealers.

It could be down to driver error but with several people reporting, it makes one wonder

I seem to stall the Yeti a couple of times if I haven't driven it for a while, I think it may have something to do with the extra drag on the car in relation to the Haldex system.

No problems on my CR170....

I noticed on my former PD engined 4x4 Octy if yer let the revs drop to below a grand then there wouldn't be a warning it would just stall...had it remapped and never had a problem

Is this a bottom of the curve fuel mapping issue on the CR140?

I agree, I had a seat leon cupra 1.9 TDI PD which ticked over at 700 rpm, used to stall that when I first got it till I started keeping the revs over 900-1000.

Interesting that a remap cured the problem.

I stalled the diesel (140bhp) on a test drive too - the dealer (sitting next to me) said it was easy to do. And I thought he was just being polite! 1.2tsi test drive much easier!
