New shitboxen Mondeo throttle issue

[GtiMik]

We had a 2008 Mondeo TDI from brand new as a work vehicle for 4 years. Never got used to the bullshit lag on take-off and it never freed up or felt any more responsive in the 160k we had it. I had a few close calls on roundabouts where it caught me out, where any 20hp shitbox manual 4 cyl would make it easily. No pics got caught out with it and was hit in the rear 1/4 by a small truck cause it took 10 minutes to get going.
Also good luck when the battery dies and it needs to be skull dragged onto a flatbed and back to Ford for everything to be reset.

same on a citroen diesel auto.

In my experience with various makes and models of diesels, is that they can take up to 20k to fully free up.

Also most modern makes and models have fairly poor throttle response, with is solely for fuel economy IMO.

Old school cable throttle FTW

I don't think it's a typical DBW issue, it's worse than the various other DBW cars I've driven

Being a slushbox makes it worse I think

I give no fuck for it's ability to cruise at high speed on some motor way. It's a city car, just like everything else in our fleet. I'd like to think that I have realistic expectations of it and honestly, once it's moving it really isn't that bad at all. It steers fairly well, it stops ok and once on boost in it's torque zone it zipps along Ok for what it's got. But the fucking torque limiting bullshit in first is shit. I can't be fucked looking up the specs, but the tojo v6 Aurion sport giggers don't do this bullshit and they barley have any traction issues and I suspect that have more power and torque than the mondeo. They are certainly faster.

What torque limiting? The 2L TDCI only has 340Nm. The gearbox is rated to 450Nm
Its just the nature of the gearbox.

simply head over to diesel tuning uk's website and get yourself a plug and play box - bumps power and torque up 30% and increases throttle/drive by wire response. i have one on our golf tdi and work colleague has one on his mondeo td wagon

Have you not driven one? It's got nothing to do with the torque rating of the box. It appears to be limited to stop it from breaking traction off the line. It's very clever, for example booting it and throwing in a heap of lock to try and light up the inside wheel, if you are still into it it will short shift up to drop revs but keep accelerating instead of the old way of dropping revs/braking whatever. It also seems to know when you are on a low traction surface like dirt going up a hill and a boot full will allow it to spin its way up.

The base wagon which i assume OP is talking about is not turbo nor dual clutch trans

AFAIK all diesel Mondeos (which the op is talking about) are turbo and share the 1 gearbox regardless of spec.

Dsmith does yours sometimes forget to up shift? I tend to shift through the gears manually on it now.

Do you leave it in D or S?

Yes turbo. Nope re forgetting to shift.

D usually. All S seems to do is hold the gear longer before shifting. It doesn't change it's behaviour off the line as per my issue with it. Also doesn't seem to affect it's traction control sensitivity, which would make sense considering that it appears the traction control is intimately entwined with the no power from standing start bullshit.

I was thinking about this on the way to work this morning (driving my diesel auto mondeo on a shitty blocked freeway and through the city in peak hour) and had to re-visit your original complaint.

I must say I dont quite follow the complaint. I have driven petrol cars for 20 years (this is my first diesel, second auto and first fwd) so I get that the the first half second isn't as pokey as you would like. I had to adjust my driving style to a diesel and it took a while but now I would never look back (well perhaps not never)

But really, what are you trying do in busy traffic that means that half second loss is effecting your enjoyment so much? I couldnt change lanes in half a second and if that half second is making the difference between a safe lane change and a line ball lane change then I would suggest you are changing lanes in a dangerous manner.

I have to agree with Rorge and Rowds. The tdci modeo is a corker. So much so I will look at trading it in on the new model when it comes out.

We're talking about the 11tybillion seconds lag before car accelerates from standstill when you mash the go pedal. Once the thing is moving there's no real issues.

[seedyrom]

Yep.
As said, it's NOT a "diesel thing". The petrol version does the same.

The petrol version is turbo as well.

But i reckon its mainly the Powershift (DSG like) gearbox with a smidgen of turbolag thrown in.

Golfs etc with DSG do it as well. And people complain about it Here are some of the answers: Maybe one will work on the Powershift

However, when you take you foot off of the brake pedal it takes a second or so before the transmission controller decides to lightly engage the clutch. Anticipate a little, release the brake and wait till the car starts to creep forward, and then hit the accelerator and watch it go.

An unfortunate side effect of this is a common complaint of "hesitation" when taking off from a standstill. This is because there is a delay between the DSG being told the brake pedal is no longer being depressed and it re-engaging the clutches.

Ways around this include:
Easing off the brake rather than quick release. The "Hillhold" function means that under partial brake application at standstill clucthes are engaged. This means that at partial brake, the clutches will be connected allowing instant power transfer.
Tapping the throttle to "wake up" the DSG and cause it to connect the clutches. The DSG will stay awake for 1-2 seconds before it disconnects clutches again if you still have your foot on the brake.

There are interesting reads on how the DSG predicts which gear you may select next based on throttle position and speed (steady, increasing, decreasing)
