Is Peugeot scamming me: Replacement aftertreatment needed?!
Discussion
Hello PH-ers,
I have a Peugeot Rifter, 1.5 hdi, 130 hp. A few days ago the EML came on, followed soon after by a AdBlue warning light and a message on the dash that after 1100 km I would not be able to start the engine anymore. The car otherwise drives normally, no loss of power and no increased fuel consumption, it's not in limp home mode. I took it to Peugeot and after a diagnostic check and a run on the rollers they told me that I need to replace the entire SCR catalyst and DPF assembly at a cost of over 2k.
They also sent me a test protocol, and after looking at the numbers for a while I'm thinking that they might be taking me for a ride with their repair recommendation. The protocol is only a snapshot of the entire test, granted, but the numbers don't paint such a bleak picture.
The fault code is P20EE 92, which is a general code for reduced cat efficiency. The technician didn't tell me of other fault codes coming up. The protocol states that at 70 mph, with a warm engine and at 30% throttle, the computer detects that NOx emissions are high and that 99.3% are not getting cleaned. It then demands 11.8 mg/s of urea, but the injector delivers 0 mg/s. The AdBlue pump is delivering 5.3 bar of pressure, so that is working. On top, the diagnostic tool predicted that the cat chemical life utilisation is 36%, and that there is very low build up of urea crystals in the SCR. The temperature in the cat is reasonably low at 330C, and crucially, the temp after the cat is higher than before it (SCRs produce an exothermic reaction, so it somehow works).
My take: this sounds like a blocked or failed AdBlue injector, not a collapsed catalyst, as the technician told me. If it was collapsed, I'd expect much higher temperatures inside, limp home mode (as the computer tries the protect the turbo from these temps), and a flurry of other fault codes coming up.
I think that Peugeot just don't want to do any fault finding, and instead just rather change the entire system at the expense of the customer. I think that I just need a new AdBlue injector. But am I wrong? Am I missing anything and is this just wishful thinking?
For context, when I challenged the technician and asked for more information he told me that "I don't have to understand this" and that "I should stop making up bullsh*t". I immediately took my car and left.

Instead of taking it to a main dealer, take it to a disel specialist.I have a Peugeot Rifter, 1.5 hdi, 130 hp.

All main dealers wnt to do (in my experience) is change bits that the computer says.
It might be a blocked injector, it might be a failed sensor, I personally would start with getting everything off & cleaned & inspected if it were mine.
Probably not that they are scamming, just completely inept.
Really, with this adblue s
t the best thing is to get it mapped out if you can because these things are just a f**king disaster. What a scam that a bloody pointless system like that, is allowed to force a shutdown and prevent you driving. It's insane.
if you can find a proper garage that can diagnose and test the system properly it would be helpful, but they are just a nightmare and just another scam forced onto poor motorists by corrupt governments.
I do wonder if they all get backhanders from the adblue/DEF companies.
