Momentary loss of power on steep downhill roads

[swoakes]

I have a 2014 vRS Diesel.

 

I have noticed that nearly every time I go over a certain hump backed bridge the engine seems to loose power for a split second on the downhill section.

 

Anyone else had this issue?

Are you "gettin' some air" dude? 

[swoakes]

 No...

 

The bridge in question is narrow and is on a RH bend. Tend to take it slowly in 3rd. As you descend down the other side the engine seems to just die for a split second and then picks up

Was common on the MKII CR engines as well.

It is a safety feature apparently.

Safety feature!... what does it save you from?

[andyvee]

Using fuel, who knows!

There were some quite heated discussions about it when the CR170 was fitted to the vRS MkII.

Yeh, it does it on my 61 vRS Mk 2....a bit unnerving sometimes but defo a "feature" whichever way you look at it (good or bad).

I got it all the time on my mkii.  Never had it once on the mkiii, even on the same roads (and glad at that because it did my head in!)

A safety feature designed for a bridge, on a rh bend, taking it slowly in 3rd gear.

Wow, I love my car.

Or maybe the car was travelling faster than the gearbox and you've had a bit of lag, a stumble if you will....

My Superb 170CR does something similar and my Audi A4 3.0 TDI did it on certain roads near me. Usually when half warm and after a few hundred yards on overrun- not responding as quickly as usual to throttle inputs, clears itself after a short time. I assumed it was an emissions control thing

I've noticed it too. Also did it on my previous mk7 golf.

Must be a VAG 'feature' as never noticed in on any other car.

Never had this on my mkII or mkIII vRS CRs.
