I think I am missing something because I can't find anything in the online Driver's Handbook.

 

Does my TDI 105 bhp 1.6 tell me when it is automatically doing a regen and does it tell my when it needs to regen and can I make it regen in some way ?

 

I don't seem to have a warning light anywhere --only a glow plug light.

 

Please can someone explain it to me.  Thanks.

You won't normally get a light on when its doing an active regen. If you do its because its already failed to complete a number of cycles on the trot so you'll need to make sure you drive it until the light goes out. Normally the tell tale signs are increase in tickover to around 1000 rpm and it might smell a bit hot. If the fans come on flat out when you switch the engine off you've interupted a cycle and you'll have to wait until it starts another. There's more info here

Since hetting mine the DPF light has only come on once that was at 800 miles.  Now on almost 2000   and light has never come on since.  I guess it's done it's own regen.  This is the first diesel I have owned.

Regeneration is carried out without any info to the user. If the ECU is unable to perform it after several attempts it will notice the user, that a long drive is necessary. 

Why aremodern cars so confusing and technical.  My old Honda civic was never like that.

look around the yeti,fabia threads about regen

 

common clues that it is doing an active regen

• tick over about 1100rpm
• fan run at high speed after you turn the ignition off
• engine seems slight sluggish (due to timing change to increase exhaust temp)
• mpg suddenly drops on a run you do regularly
• strange rubbery smell when you get out of car

have a look in the book of words that came with your motor, will give you a list of things and which warning lights to be aware of if it fails to complete a regen fo a period of time, ignore this at your wallets peril as a replacement for a clogged DPF is not covered under warranty and an expensive mistake

 

one other thing, certainly on the fabias and yetis, they seem to regen more often in cold weather, also the regen process seems to be better if you drive in 4th rather than 5th in winter as you don't seem to take so long to get the DPF up to temperature to burn the soot of as not so much cold air cooling the DPF

Thank you to all who replied.

 

When / if my car tells me it needs a regen what indication is given ? Where is the light and what does it look like?  Is it the glow plug sign that flashes or something ?

 

The other day I had to nip down a motorway and took the chance to keep it in fourth gear and do 65/70 for about 15 miles. Get a few revs on and knocked a hole in my fuel gauge but did very little harm to my overall average MPG

Sorry folks. Cancel all that--I've found the warning light.

 

It's in the rev counter top left.  Why had I never seen it ?  When I turn on the ignition it shows for what I estimate is a millionth of a second.  never seen (or failed to see !!) such a fleeting warning light ever.  But I'm happier now I've found it.

 

Thanks

It would be really, really nice if they put a green DPF light on the dash to show when its regenerating, so you have some idea of what its doing.

I'd agree with that, I don't have a TDI so doesn't affect me but it seems odd that it's standard practise to try and do all of this stuff without ever letting the driver know, if it's doing a regen it should tell you so that way you can take a more scenic route home (or have a spin around the block etc) to give it time to complete instead of continually turning the engine off mid-cycle because you don't know it's happening.

Diesel particulate filter? (diesel engine)

 

The diesel particulate filter separates the soot particles from the exhaust. The soot particles collect in the diesel particulate filter where they are burnt on a regular basis.

If the indicator light ? lights up, soot has accumulated in the diesel particulate filter.

To clean the diesel particle filter, the vehicle should be driven at an even speed of at least 60 km/h »  at engine speeds of 1 800 - 2 500 rpm for at least 15 minutes or until the warning light goes out with the 4th or 5th  gear engaged (automatic gearbox: position S)  when the traffic situation permits it.

The indicator light exhaust warning  only goes out after the diesel particulate filter has been successfully cleaned.

If the filter is not properly cleaned, the warning light does not go out and the warning light coil lamp begins to flash.

The following is displayed in the information display:

Diesel particulate filter Owner's manual!£ The engine control unit allows the vehicle to run in emergency mode. After switching the ignition off and on again the warning light, the indicator light engine check lamp also lights up.

Seek help from a specialist garage.

 

 WARNING

? The diesel particle filter achieves very high temperatures. Therefore do not park in areas where the hot filter can come into direct contact with dry grass or other combustible materials - risk of fire!

? Always adjust your speed to suit weather, road, region and traffic conditions. The recommendations indicated by the warning light must not tempt you to disregard the national regulations for road traffic.

 

 CAUTION

As long as the warning light lights up, one must take into account an increased fuel consumption and in certain circumstances a power reduction of the engine.

 Note

? To assist the combustion process of the soot particles, we recommend that regularly driving over short distances should be avoided.

? Using diesel fuel with an increased sulphur content can considerably reduce the life of the diesel particle filter. A specialist garage will be able to tell you which

countries use only diesel fuel with high sulphur content.
