can anyone explain what "pef"?fuel additive is in peugeot cars and is it an absolute neccessity to replace it?

Question

my car keeps telling me that fuel additive is low and apparently this stuff is really expensive to replace.I just wondered exactly what it is and does it affect the performance of the car?

Answer 1

The PEF is a particle filter developed by Peugeot to reduce carbon particle emissions on it's diesels.It was done as part of Peugeot's effort to clean up the diesel exhaust
Read the piece I found on this Irish site:

THis doesn't answer your question but I will ask around at work tomorrow and get back to you.

Look here:

It is required for emissions control. Some diesel engines use a particulate filter to reduce soot emissions from the exhaust. This soot needs to be disposed of somehow and that's where the PEF additive comes in. It is used as a catalyst to burn off the soot trapped by the particulate filter. You don't replace it, but do need to top off the reservoir at regular intervals. The link above specifies 48,000 miles.

I'd suspect that you could fail the emissions portion of your MOT if it's not working properly, i.e. topped up properly. The exhaust system would eventually become clogged without it as well, hurting performance as well as probably requiring early replacement.
