Liquid In The Exhaust Filter?

[Grandc4]

I have recently bought a 2011 grand c4 and im loving it. Not had far to drive it yet although we have done 140 miles already haha. ( since Saturday)

 

A work college has told me that if the part breaks in the exhaust is then it cost a lot? The liquid costs quiet a bit apparently... He is polish and speaks okish English. Although he is a mechanic on weekends I think.

 

Can anyone fill me in on what he is on about? Some thing about the liquid is there to cut down the emmsions? I won't have to worry about if for 3 or 4 years?

 

So many questions....

The liquid is Eolys fluid and it's contained in a hidden 5litre tank at the n/s end of the main fuel tank.   When you fill up with diesel your onboard computer injects only milli-litres of fluid.      Every 300 or so miles the system regenerates by  making the particle filter very hot so that the particles of soot are burnt instead of being blasted out into the atmosphere.   The 5 litres of fluid will last up to 90-100K miles, by which time the tank will need to be refilled and the on board computer reset.      At the same time the particle filter may need replacing but often it just needs a clean.

 

To keep the particle filter working at its best, it's advisable to follow the recommendations and use low ash oil when changing the engine oil.   That's an oil to a C2 or C3 standard

Thanks for the great reply. My friend also said that he would hook it up to a computer and cancle the message and the light that would normally appear in your dashboard. This isint a great idea is it?

 

So it is a costly thing... Our car has just done 45k miles.

Eventually - maybe around 90-100K you will get a warning on the dashboard that your fluid level is low. If you ignore it, other warning messages will come up together with the EML being lit. Ignore those warnings and the engine will go into limp mode. That means it won't rev at more than 2000rpm. Sure - you can erase the warnings but they will quickly return. The answer is to refill the additive tank with Eolys fluid (about £40 per litre) and maybe get the particle filter cleaned. Both jobs are do-able DIY - although you'll need a Lexia to reset the counter for the additive.

Well it's got a few miles Togo befor there. So I will do what's right and best for the car and fill it up when needed. £200 woah :) I'll prepare for that one haha. Trying to look at bike racks for citron c4... I didint realise how much they cost!!
