2002 2.0 HDI Minimum Diesel Additive warning - piersmcg
Peugeot 307 SW 2.0 HDI 110 - 100K miles

The centre console is coming up with the warning: MINIMUM DIESEL ADDITIVE LEVEL.

There is another thread on topping this up, but Screwloose mentions servicing/replacing the FAP system as well. What is this, and is this expensive? Can this be done outside main dealers?

Thanks for any information.

You've let your additive run low - kick whoever's been doing your services.

As I've droned on about before; by the time the additive is gone, then the FAP in the exhaust will be getting full of unburnable regeneration residue. The only practicable [and legal] way to deal with that is to fit an exchange FAP.

So; you need, FAP, fill and re-set additive ECU. You'll usually also need a fuel-cap sensor and often a FAP pressure sensor. If the additive ECU refuses to co-operate, one of those too.

Very few places outside a dealers have the knowledge and equipment to do this job; shop around - the bill will, typically, be somewhere between £600 and £1000+. Leaving it until it blocks completely will guarantee it'll be the higher one.

Beware the shysters now getting into this lucrative little racket. If the job's not done properly, then it'll just come back again - only worse.
