Ever wondered what happens when you push the handbrake button whilst driving ?

Another link on that page takes you indirectly to Tenneco, an American-based company who apparently make DPFs for most car makers. To further confuse, they state:

"Diesel particulate filtersfor original equipment (OE) applications remove particulate matter from diesel engine exhaust in a closed loop system. When gases carrying particulate matter flow through the filter's substrate walls, particulate matter is trapped and collected in the filter. A regeneration process, triggered by the engine management system, then burns off the soot using either a fuel borne additive or a catalytic filter coating. Filters are completely cleaned or replaced at a service interval between 150,000 and 225,000 km.

DPF for OES applications work in an open loop system wherein there is no communication between the filter and the engine management system to trigger the burning process. Instead, the design and the coating support continuous regeneration of the filter."

Open loop, closed loop - the first line in each paragraph seems to confuse the issue even more.

So now we (don't) know!

Holding down the parking button whilst driving WILL stop the car even if you are accelerating! At lower speeds the car comes to a very sudden stop. At higher speeds (40mph+) it slows down before stopping! Quite fun actually. probably not a good idea though.

I thought you had to keep it pressed too. Maybe there are different scenarios that it takes into account (speed < x apply full brakes, speed >=x ensure button is still pressed to apply brakes).

I take it you've tried it then

Should be no different to an old-fashioned handbrake.

Been reading this thread and just realised how old it is.

I have definitely seen my hazards lights activate under heavy breaking from 50mph to a standstill. The lights on the dash light up and the clicking noise is obvious.

I did try putting the handbrake on while driving, on a private road and seem to remember it beeping and displaying a message something like "don't be silly", but my memory is fuzzy, and it would have been only around 10mph. I'll try it again.

Also mentioned in this thread, is the DPF and reference to the Skoda Suberb. Their was a big thread on BriSkoda a while ago about this engine in the Skoda suffering with the problem mentioned. Big surprise was that the Skoda 140bhp engine in the Suberb (at the time) was not the same engine as we know, and I'm sure they found out it was an 8 valve, weird. The chap concerned was serious about taking legal action over it not being fit for purpose. There was a canister of gue in the inner wing of the boot which would feed into the DPF, or whatever it was.

o yes!!

I read somwhere that to use the handbrake as an emergency brake you need to keep it pressed. should work at speeds up to 70 mph!!

Foot off accelerator, press and hold handbrake button.. Car will stop very suddenly, ABS stopping wheel lock. Just brace yourself and steer! Didn't notice if hazards flashed at the time though.

i can honestly say it really bugd me when i first got mine and i tested mine on grass... if u hold the button in and dont let it out it will lock the wheels at any speed!!! beware, see for yourselfs...
