ANTI POLLUTION FAULT Problems!!!

[bestbass42]

OK, Got a 2005 206cc 2.0ltr with 109,000 miles on the clock. The car drives ok for its mileage but after stopping then starting up again the ANTI POLLUTION FAULT comes up in dash display & Engine management light comes on. When this happens the car goes very 'chuggy' like its down 50% on power & rattles on start-up.

The car has been to our local garage & has had fitted new plugs & new coil pack & still the same. Diagnostics came up as # 4 injector, changed that & still the same & still saying # 4 injector!!! Mechanics came to the conclusion it MUST be the ECU. After speaking to mechanics from another garage they have had the car, reset everything, pressure tested the engine & lights disappeared. Drove car home, went all round the block & had no problems. Started it up 10 minutes later & BLEEP-ANTI-POLLUTION FAULT & engine light come on again & car starts 'chugging' badly!!!!

Does anyone know what this could be??? I Have read it could be tappets or rear Lhamba sensor etc. Has anyone had this problem and actually found a solution & got it fixed??? It seems on here people report problems but never come back on when problem is fixed. I'm a motor trader & this is a car that a customer returned to us because of this problem. It wouldnt be so bad if it didnt affect the running of the car but it drives terrible when these lights are on!!!

Thanks in advance...

If hydraulic tappets then normally one gets the symptoms from cold start and more often than not in cold weather i.e. winter. People selling cars with this problem often warm up the car beforehand so that the fault is not apparent when the prospective buyer test drives it. The new buyer finds there is a problem the next morning when starting the car from cold. The cure is to fit the hydraulic tappets from the 1.8 engine.

Lambda sensors can be problematic and if these are at fault replacement of one or both ought to be the fix.

New plugs? Hope that the correct Bosch ones were fitted. Peugeots don't seem to like other makes such as NGK.

Is it fuelled with decent petrol such as Shell V Power, BP Ultimate rather than cheap supermarket fuel? I won't use anything else in my wife's 206cc (which is a 1.6).

I'm not a mechanic, just an enthusiastic car owner but I've been a moderator on this forum for years and have a fair knowledge of the posts on here. Feel free to use the search facility if I haven't pointed you in the right direction.

Good luck.

Cheers mate for the reply. Yes when we first bought the car it was running on fumes so i filled it up with V Power. First time after filling the lights went off. The new owner filled up & said he used good stuff but of course i carnt be sure. But since its been back with us i have again filled it up with V Power.

No doubting the 206cc is a really nice looking car but I've got to say as a motor trader they are nothing but trouble!!! Great sellers yes as the women love them but almost everyone we've had has had problems. If its not the roof deciding not to open while showing a customer the car to AIR BAG FAULT to ANTI POLLUTION FAULT they are nothing but a pain in the backside! We sell a lot of Fords mainly Pumas, Fiestas & KA's and hardly anything goes wrong on them! Even the 10-12 year old Pumas & Fiestas the only real problems are heater control valve (£17 & 5 minute DIY job) & the Lambda sensor (£25 fitted).

With these 206cc's it seems that it could be a whole host of problems for every little thing! You'd of thought if a car has a display saying ANTI POLLUTION FAULT it would also put in the dsplay what that fault was!!! I Mean now we're talking fitting tappits which is going to cost more ££££££££££££££ & if that dosent cure it Lambda sensors & again more ££££££££££££££££!!!-& still no guaranteed fix!!! It really is ridiculous that car manufactures can get away with this because from what I've been reading this is a very common fault on both Peugeot's & Citroen's.

Take a look at this thread regarding the throttle position sensor:
http://www.peugeot206cc.co.uk/viewtopic ... 6&p=116087

Let us know if it helps. Careful though, that one was a 1.6 engine.

Spurious warning messages are often a sign of the battery on its way out, or sometimes an incorrect battery fitted ( a cheap hatchback battery instead of the pukka 206cc spec one which is taller ).

I have to agree with your comments. I don't think I'd buy a high mileage modern Peugeot or Citroen, or a Renault for that matter without expecting problems. I sympathise with any car trader dealing in them.

Do you know the exact fault code? It could be the wiring to #4 injector. Does the workshop you use have a set of "noid lights" as they will check you are getting pulses to the injector or not?

UPDATE!!!!!!!!!!!!!!!

OK, so the car has now been to THREE different garages. First two couldn't sort the problem out so we took the car to 'JUST PEUGEOT'S' which is in Darlaston, just outside Wednesbury, West Midlands (5 mins from J10 M6). We really should of took it there first as they are Peugeot specialists but as we have an account at our local garage we took it there thinking they'd be able to sort it out.

Anyway, cut a long story short they ended up changing all four injectors & so far-touch wood-the Anti Pollution Fault & engine management light have stayed off. Cost was £120 including labor.

Was also told that on these cars the injectors are back to front-ie what you think is injector #1 is really #4.

There is still a bit of clutch judder on pull off which is cured with a bit more revs but at least the car drives ok now (fingers crossed!!!)
