Maybe it's because I've not had a turbo-diesel before, but although I really enjoy this car, the one thing that annoys me is the turbo lag.

This occurs especially after slowing down - for example slowing down for a red light, and the engine is on overrun and low revs. As you approach, the lights change so you apply throttle...but then you need to count to 2 before the power comes in.

Also more pronouncd when the car is warming up. There have been a couple of occasions when I've been filtering into traffic from a side road when you go for a gap and simply, nothing happens when you floor the throttle! Count 1....2... and the bang- the power arrives in a big wallop.

Is this behaviour common to all of these cars, is it the auto - or is it my car in particular?

Your comments appreciated.

is it DSG? or is that only on the 2.0?

Not DSG - just the usual slush-matic.

I just found that I had to drive differently, a combo of any diesel and an auto box is never going to set your pants on fire.

yeah, I think the Auto really isn't helping things... could always use the manual selection to make sure the revs are up before booting it

I dont know what settings you have on your box but if i need to do as you describe I either move it to S or switch over to manual and drop it down 1 gear. Mainly I dont bother though, think you need to get one of those VRS thingies if you want the performance from a Octy.

I 100% disagree. IMO, the 2.0FSI, 2.0TFSI, and both the 1.9PD and 2.0PD engines all offer excellent performance.

I have the 2.0PD Tom and even though the performance is good when you are up and running, when you want to gun it , there is a delay, even with the DSG. Unless I have a duff car that is the reality. I also find that the DSG, as good as it is, does jump a bit when you are driving in D quickly. Hope I dont have a Friday car.

reeeeeeemaaaaaaaaap....

I've got the 2.5 v6 Tdi, and turbo kicks in at about 1700 rpm, maybe the same in the 1.9.

Best way round it is to use BP Ultimate. The low down power difference is fairly remarkable. The 1.9 might not make as much use of the advanced fuel though. I had been using it for about 3000 miles and engine is so much quieter.

I have heard it is common across many VAG 1.9 units. Mates got an 1.9tdi A6 and he thought it was dangerous at roundabouts initially.

Hi,

I'm no expert on this, but my son is, and he tells me it may well be the "fly-by-wire" throttle that causes the delay rather than the turbo lag. My 1.9 130 TDi Superb is manual, and though I don't notice a lag as such it is easy to stall if I'm too quick on the clutch when pulling away.

Mike

just a thought, but could your MAF be contaminated? there's *some* turbo lag on the TDIs but it shouldn't be 2 seconds' worth...have you a good tuner near by?

I'd say the delay in throttle response is perfectly normal and can be due to turbo lag. Could be just the fact you've come from a petrol car.

Hi Mike,

I have just got back from driving my fathers Rover Diesel Turbo, I am going to shut up as my 2.0 now feels like a Ferrari after driving that piece of rubbish, by the way Fly-By-Wire makes response quicker I think.

Hi Rob

I too have the 1.9PD Tiptronic (Suprise really given my username! ) and yes it can be somewhat. I could be wrong, but I seem to recall Ross (Lummox) saying that the box selects 'neutral' while stationary, hence the delay when you then stamp your foot down.

You do get used to it, and adjust your thinking when looking at gaps. IIRC the auto has better torque than the manual, so I don't know what gains there would be from a remap, besides horsepower.

All the Best

My Superb is manual, and I also drive new Transporter T5 with 5 cyl 2.5 pd130 and 6 speed tiptronic. Both suffer to a degree some lag which can catch you out usually on slowing down then accelerating before being stationary. The auto van is worse than the car as the box is controlled by me.

I suspect the electronics of the auto box exagerate the engine characteristics.
