Have just bandaged and gun gummed a hole in the exhaust part of the cat this week, but have now got an anti pollution fault come up with engine light after driving around the block.

When the hole was there i didn't get this message, does anyone know how to rectify this? I've double checked the exhaust system by hand to make sure there are no leaks.

Could this just be the ecu throwing a hissy fit because it's been driven with a hole in for so long?

Have an MOT booked saturday and need it to go through.

Car details would help and getting the car read on pp2K is vital. Anit pollution is Peugeots way to tell you you have an engine fault but we are not going to tell you exactly what cos we are Peugeot!!From that then just because you were working on the exhaust does not necessarily mean you have a exhaust related fault, Hence need to get the car read. I have a reader if you are near I would read it for you.

It's a 2003 1.6 16v Rapier, I've fitted a new rad yesterday and replaced the manifold gasket this week also but the fault hadn't appeared after. The only work i did today was a spot i missed on the exhaust sealing it completely and securing the cv boot.

I did notice just that the back box sounds like it has water gurgling in it so might be contributing. The coolant is also a little low from where i refilled the system yesterday but will wait for it to cool down before topping up.

I really need to invest in pp2000 to be honest, it's been one thing after another with this car since i got it,mainly cheap fixes but lots of them! lol

I'm going to have a look tomorrow as losing light now. Twice now i've booked MOT and had a light come on, thankfully i don't think they can fail for engine lights but emissions are a different story.

The 'antipollution fault' error message covers a wide range of potential problems. You need to get live data to get an idea as to what the actual problem is as the error code will only be generic.

reload3d same as mine then although mine was abs(saga) and limp mode(still in but am tracking a lead thanks to pp2k.) As mentioned the title does not mean it is emissions! But if you have not done so since getting the car a good all filter service might do it good. My offer is still valid if you live myway.

I did the filters in January both cabin and air filter along with plugs, the oil filter was also replaced in January when the oil was changed. Iv'e just managed to scan the car with ScanXL Pro and it's showing the only faults as the following:

p0141 02 Sensor Heater Circuit Bank1 Sensor2
p0140 02 Sensor Circuit No Activity Detected Bank1 Sensor 2

I'm guessing Sensor 2 is the one in the Cat pipe underneath the catalyst itself and not the one in the manifold?

It's bloody sods law as i have a spare manifold sensor, does anyone know if the sensors are the same ie will it be ok to fit a green plug to blue socket?

The o2 sensor wasn't the problem i replaced earlier and still the same, i've decided to take the car off the road and overhaul the engine and gearbox over summer, so it's back to driving the zafira as the daily for now.

The clutch is on the way out anyway and the engine is quite noisy and lacking most of the time, so the plan is to strip out the head and gearbox and throw a new cat in, clean and replace all moving parts that are worn and check the piston rings at the same time. Replace belts and pump while out and also clean and protect the car engine bay and underbody with some valvoline tectyl before re-fitting everything. I'll bung a new head gasket on at the same time.

I have to drop the rear axle to replace bushings and replace bushings on the front suspension arms also so just aswell strip it nearly completely and rest the body on axle stands while i get the work done. I might even treat it to a respray while everything is off as the paint is starting to peel in places as i had planned to get a body kit for it in a few weeks.

Lots to do the next couple days stripping out, when i look in my shed it's a very minor job in comparison, the mrs junk is gonna take some time to clear!.lol

You have set yourself a task and a half there! Might I suggest that it might be a good idea to solve the problem before you strip for two reasons. One its a job out of the way and two you might have to start stripping again after all your nice work is put back. Also I find its best to do a bit of the car at a time by areas. One it means you don't fill all your valuable space that could stay on the car and two there is always the possibility that something comes up and the overhaul stalls, and you get involved with another car etc etc!
Best of luck and keep us informed as you progress.
