Citroen c3 error code P2015 64
Discussion
Anyone had this issue before? Any idea how to resolve this?
Symptoms have been rough idling, sluggish, draining fuel.
Cat glowing red.
Changed inlet manifold sensor, throttle body sensor, checked manifold with garage, swapped cat and O2 sensor.
When remove pipe to brake booster pressure sensor, car sounds normal, changed the part, no luck. New cat glowed red almost instantly but didn't when removed pipe to brake pressure sensor.
Anyone help or advise? It's a Citroen c3 2018. Wet belt changed a few months back, had the belt checked also.
Thanks

A "glowing red cat" is frequently caused by unburnt fuel entering the cat & being burnt off on the cat substrate.Symptoms have been rough idling, sluggish, draining fuel.

This CAN obviously be caused by several things some of which are:
A collapsed cat.
Over-fuelling.
Mis-firing.
Ignition timing.
Faulty MAF.
Good advice would be NOT to drive it like this as it is a VERY obvious fire risk and can cause further damage if the cat itself is not the problem.
A few points of note/questions.
IF the cat was not the issue (as it has been changed) further use like this would be very likely to ruin the cat, so have you continuing to drive it since?
Assuming the pipe that you mention is from the inlet manifold, by removing it and allowing more air in would make me think the issue could be MAF/air inlet related, so you need to start by going through the inlet with a fine tooth comb checking for air leaks or anything else amis, at this point a genuine MAF might be a good bet if you want to swap something.
Coil(s)/injector(s) could be an issue, but another question would be how good is the code reader that has been used?
Agree with E-bmw, especially about not driving it while the cat is glowing.
On the code itself: P2015 is the generic "intake manifold runner position sensor/switch, range/performance" code, and the "64" on the end is the failure type, which in the standard list means a signal plausibility failure. In other words, the ECU is getting a signal that doesn't make sense against what it expects, not necessarily a dead part. Generic readers often show the generic wording, and PSA doesn't always use the codes the same way, so I'd get it read with a proper PSA-level diagnostic tool. That gives Citroen's own description and lets you see the live data.
A couple of things I'd look at with that tool:
1. **Fuel trims.** If the short and long term trims are pulling a lot of fuel out, it's confirming over-fuelling, and the trims with the pipe connected and disconnected will tell you a lot. The fact that it runs better with that pipe off is a big clue that it's reading something wrong on the air or pressure side and fuelling to match.
2. **Cam/crank correlation.** As the belt was done a few months ago, check the timing values in live data. A tooth out can cause rough running and odd air readings.
3. **Oil and vacuum side.** On wet-belt PureTechs, belt material breaking up can block the oil pickup and has affected the brake vacuum pump on earlier cars (there was a DVSA recall on 2013 to 2017 builds). Yours is probably outside that range, but it's worth running the reg through the GOV.UK recall checker and asking whoever did the belt whether the sump and pickup were cleaned.
What reader was used, and has the car been driven much since the new cat went on?
