Anyone got a latest shape VW Passat 2.0 TDI?
Discussion
As per title.
Reason that I ask is that I have. 2012 model, 4 door, 2.0 TDI 140 PS Bluemotion with 56k on the clock.
I've noticed something with the car - always have done and wondered if it was a new-ness matter. But car is almost out of warranty so can't be new-ness now.
Thing that I've noticed is that as you go down a hill in it - and generally don't accelerate, i.e. foot of 'the gas' and let the car take itself a little bit - the car seems to pull back a little. Perhaps like the engine's picked up and is starting to gradually slow itself.
I don't believe I've changed my driving style. The last long term car I had was a SEAT Ibiza Cupra 1.9 TDI which never did anything like this - however, it was on 108k. Perhaps things were considerably looser.
Just wondering - has anyone else noticed this? I thought it was a problem at first - doesn't seem to have done any harm to the car - but my Dad noticed the other day when he was in the car with me and asked me what I was doing and so i'm guessing it's not really improved (if improving is the word!?).
Safety feature?

My Seat Exeo does actually the same thing - same engine /ECU I guess too being a Tdi 143CR - it's being discussed on SeatCupra now.Reason that I ask is that I have. 2012 model, 4 door, 2.0 TDI 140 PS Bluemotion with 56k on the clock.

It's definitely a feature rather than fault, or at least one they all seem to share - theories are either it's something to do with economy/ emissions and cuts the engine when gravity/momentum is enough to maintain speed or that it's caused by the ECU cutting it because it senses the car accelerating when the throttle pedal is closing and is a safety measure.
It's barely perceivable sometimes on mine, I feel it but passengers don't - but sometimes it's quite obvious and living in Wales means I'm either climbing a hill or going down one so I notice a lot.

As mentioned, it's a feature of the car, applies to the A4 with the same engine as well:

CRD TDI Holding back after brow of hill
Release date: 29-Jun-2010
Customer statement / workshop findings
Customer complains of vehicle “holding back” or a hiccupping phenomenon when driving on roads with aggressive changes to the gradient (e.g. humpback bridges or on undulating roads where the terrain goes up and down) and where the vehicle is driven with light throttle application.
Technical background
Audi vehicles are fitted with an ECU with a monitoring concept, which constantly compares the drivers throttle input against the vehicles speed (measured by the tyre speed sensors). If necessary the engine torque will be controlled to ensure the driver’s throttle request is maintained.
This can lead to a reduction of torque on downhill roads compared to the torque given on flat roads with the same throttle position. The reduction of torque on downhill roads is normal behaviour for all current Diesel vehicles.
This does not affect the maximum engine torque which can always be achieved by pressing the throttle pedal, regardless of the gradient of the hill.
Production change
No change
Measure
No service solution. "

Thanks to you both for this.
Glad others are feeling it - thought it was just me! Couldn't even describe it properly to a work colleague.
Interesting feature mind!
SEAT Exeo - any good? Potential change of job means i'm going to probably have to buy my own car. Fancy something VAG again and enjoyed my last SEAT. Need family sized car really and Exeo nicely cheaper than equivalent Passat.
