I have a 2.0tdi 140 Octy that seems to have an uneven power delivery. The turbo spools up around 1700rpm then noticeably kicks again around 2000rpm. Is this normal for this engine? Does anybody elses car do this? I find I have to drive around the issue to maintain a smooth drive.....

My car is the later version with the lower emissions output (145g/km) bought new late Sept last year, could this recalibration have introduced this?

Any help would be appreciated before I decide to book it into the delaer to have a look at it.

I have an June '06 version and do not have this problem so it might be a 'feature' of the later model but it does not sound right. I do find the power delivery a bit vicious in first but thats just high torque low gear, power is very smooth in all other gears..

If this is consistent than I would get it back to the dealer ASAP

No problems of that ilk here with a Marcj 07 TD140 4x4 - so it could need a trip to the dealer?

Tbh the PD140, whilst better than the PD130 in this respect, still has a very peaky power delivery, its a characteristic of this engine.

I have driven an A3 TDI140 (55 plate) that didn't exhibit this tendency, and although these engines are quite agressive in their boost build-up, to have two steps in the delivery doesn't seem right. Maybe it's a problem with the variable vane geometry not adjusting smoothly....?

I think I'll have to get it to the dealer, unless someone else knows if it is a characteristic of this later engine?

Mine is 06 and has the same behaviour. Friend of mine has 05 and also the same. I know what you mean. If you want to take over the car in front of you, running bellow 2000rpm doesn't give almost any power to accelerate. So, before starting to accelerate I make sure I'm on more then 2000rpm. Sometimes it can be tricky as I forget about 2000rpm and start accelerating. If there was little space to take over I find myself in trouble. In other ocasions, on more then 2000rpm, I have to be careful not to charge accelerator pedal fully because it responds with so much power that sometimes I loose control on steering. So, two years now and I'm still getting use to TDi 140. All my previous cars were gasoline with constant power response. That's the reason I find this kind of power response a bit complicated. Other poeople I know, who have been always on TDi's, see no problem at all. So, that's the way it's suppose to be.

My last car was a Focus TDCi that suffered from the traditional turbo lag too, but it didn't have a second step once the turbo was spooled like my Octy hence why I'm thinking it's not right.....

Mine aint peaky

Mine aint

Mine pulls like a train from about 1600 rpm to just shy of the red line.

The 2.0TDI was way too 'peaky' for me, and we test drove a few different ones to make sure. It is quite interesting how much they vary!

Decided to go for a second 1.9Tdi, which is much nicer in its more 'gentle' power characteristic.

......Horses for courses though, I admit!

I disagree that is it peaky. Sounds to me like the DMF is a bit soft and taking up the power delivery then springing back at about 2k rpm.

If you are accellerating on say , half throttle [1] from 1500 rpm there is the obvious noticable step in torque as the turbo comes in at 1800 rpm , but if you keep the throttle constant there is another smaller step at about 2500 rpm.

It's not as noticable when accellerating flat out , but I've seen dyno plots from other people's PD140s and you can see it on ther chart

[1] for all the pedants , yes I know diesel engines don't have a throttle but you know perfectly well what I mean.

Is that something that can be checked by the dealer?

Could it be a variable turbo geometry problem not closing properly at low rpm to provide the stronger bottom end - then only working properly from 2krpm?

Having a 55 plate 140with dsg box and now done 24700 miles we do not have any problems,if i have to put my foot done the only problem i had at first was with moment of front tyres screech. As for the comment about looking at what revs before changing, jeeze it sounds dangerouse. I have always driven by the seat of my pants knowing most things from tyre stones engine etc.

Is there a method using VAG com to exercise the VNT vanes?

Hear hear! It's just the nature of the engine. There are two noticeable steps on the power delivery when accelerating, that's just the way it goes. On full throttle, it is not that noticeable.

Every single 2.0 140bhp TDI I have driven behaves exactly like that. VW, Seat, Audi and Skoda. So does mine.

You'll get used to it.

Under normal conditions or full throttle you can't feel it , but last night I deliberately drove so this would be more noticable , and it is definitely there.

mine does too

I've driven the 170 TDi VRs and the power delivery was pretty smooth but I don't know about the 140.

my 2008 is also a little peaky at 2500rpm.

after removing EGR hose it came considerably more peaky and I had to lenghten VNT shaft one turn to get it work more smoothly.

My friend has older II and he said that he dont have such a kick anuwhere, but hi has some flywheel chatter at lower rpms.

My guess is that Skoda has lowered injection quantity at low rpm to avoid flywheel chatter and 2500rpm is the point of more IQ.

I have not yet logged IQ with vag com, but MAF and MAP figures are far from requested at low rpm and my friend said that he had really close.

My stock power was okay. I measured it at 3000km, it was 161hp/360nm so its well above advertised.

I should go to measure my hp this weekend with EVRY mod.

edit: this is non DPF / 16 valve.

In Denmark have we (until 3 months ago) 2 models 2.0 tdi now all have dpf

without dpf = 16 valve

with dpf = 8 valve

Both have 140 bhp and 320Nm

Can it have some influence on the power peak ?
