relax the cacks. school's in session.
you're lucky you have the new avensis that tells ye "DPF full" on the instrument panel. my aulwan has the same avensis as yours and she does tell me "the car is sayin DIV full again what does that mean". the new avensis does'nt even go inta limp mode like the T27 model that i had. you were notified by a full dpf by virtue of a myriad of 6 or 7 warnin lights. i remember the first time it happenned and the car lost all power. i was brickin it. obviously i did'nt know what was happennin or what a DPF was.
Diesel is a dirty burnin fuel. A DPF absorbs all the soot and carbon like a sponge that otherwise would get belched out the exhaust in plooms of black smoke like the old school diesel lorrys. Problem is the DPF gets full. The way to empty it is to blast a lot of heat through it. Dipetane is great stuff. It works my raising the octane number of the fuel which means you get a more efficient burn of the fuel. more efficient burn means more power, more heat created, less oppurtunity for soot to build up in it.
how i remedy my aulwan's DPF full or any DPF full car;
1. Wait till the tank is nearly empty
2. Grab the fuckin car keys off her and go to the petrol station
3. Throw a full bottle of Dipetane in
4. Fill tank to about a quarter full on top of the Dipetane to make sure it mixes well and you get a strong concoction of souped up Dipetane/fuel
5. Floor it up and down the motorway in a loop holding the revs at 2500rpm to create maximum heat for the soot in the DPF to turn to ash and empty out.
6. Process can take anywhere from 30 mins to an hour dependin how full the DPF is.
7. DPF full message will automatically dissappear
8. It's advisable to do an oil change afterwards because holding the engine at 2500rpm for such an extended time will riddle the oil.
9. To keep the DPF in good order add a little bit of Dipetane at every fill up and every once in a while on the motorway gun the car at 2500rpm for 10 minutes or so.
Mechanics simulate this by doing a "forced regeneration" of the DPF. They'll connect a computer and rev the car at 2500rpm in the garage for 30 mins but the engine ideally hasta be working very hard (up a hill with 4 yanks on board) to speed the process along. If that does'nt work they'll connect a hose to the DPF and wash out the soot and build up carbon. If you get a pain in your nuts with the DPF keep gettin full you can have it removed. pricey though because they're usually buried behind the engine. once they're gone you'll get a strong fume smell out the exhaust which can be remedied by using Dipetane at every fill up.
