Damsel in distress.

Mr Google is only of limited use. Does anyone on here know anything about cars?

I have a 2010 Peugeot 207 1.4 petrol.

The little engine light doesn't go out when the engine starts and the on board computer says that the antipollution control is faulty.

Handbook says it is the Engine diagnosis system.
Light is fixed: The emission control system has a fault.
Observations: The lamp should switch off when engine is started. If it does not switch off, contact a Peugeot dealer urgently.

So the questions.

How urgent is urgent? I won't be able to get to a garage until tomorrow, if I am really lucky.

Can I drive it without buggering the engine? I had planned a few errands today.

Can any garage run the diagnostic tool to get the diagnostic codes, or does it really have to go to a Peugeot garage?

I suspect the exhaust as it is a wee bit rattly, so should I just go to an exhaust place and ask them to look at it?

Have you tried You Tube ? Its a mine of Info. I managed to fix my car before the AA man got there by watching a clip after entering details of the fault.

AA man was well impressed ! And no , I hadn't run out of petrol , it was a gear problem.

Morning Minnie. Sometimes these little lights come on for the flimsiest of reasons but I can understand your worry. Have you tried ringing any Peugeot dealerships? Their service centres will most likely be closed but the sales departments will be open for part of today and there may be somebody there who could put your mind at rest. Most dealerships open at either ten or eleven on a Sunday.

Thanks, Battie. Could try that. Had assumed that they would all be closed today.

A rattly exhaust and emission control system fault could indicate a sensor on the catalytic convertor - I wouldn't think it would bugger the engine driving it. Maybe the rattle has dislodged/damaged a sensor or the exhaust is leaking slightly.
I would think many garages could diagnose the fault, manufacturers scare people into rushing to their nearest main dealer cos the car is going to blow up...

Have a gander at this Minnie, see if any other symptoms are present.

Sounds like sensors on the exhaust to me.

Thanks folks. Advice from friend of an FB friend who works in a garage, is that the urgency is because the emissions probably mean that it is above legal limits. They said if I am going to use it around town, no problem unless I got stopped by the police, but unlikely to harm the car if I am going to get it checked out tomorrow. He said to go to my tame garage first and ask their advice, as a visit to a Peugeot dealer is likely to cost and arm and a leg and the usual guy may well be able to fit me in tomorrow and fix it.
I am a bit cautious with warning lights after the fiasco with my lovely Focus, when the garage serviced it and didn't replace the oil afterwards. It's a long story what happened, but it involved a long north to an MSE meet and predictable results on the way back.

And thanks guys, the friend of the friend, said he thought the sensors likely too.

I agree with Hierophant.


I am not an engine diagnostic specialist, but I ran a business with my ex for 28 years discussing engine tuning and fault diagnostics with him and what Hierophant describes sounds very familiar.

The problem might arise when you come to your MOT as it might fail due to the gas emissions and "Lamda" reading.


My daughter ran her old Yaris for a few years and got away with it because of the year of her vehicle 2001, but later changes might affect this.

A faulty sensor can also cost several hundred pounds or a few quid, depending on the manufacturer, some are part of the exhaust, some are not.


It can also contribute to using more fuel, and if the combustion is wrong, then a less than perfect mix could, over time, contribute to carbon building up in the spark area and eventually lose compression on a cylinder or two. (I bit like cholesterol in the heart and arteries causing faults on an ECG in a human...lol).

vanman,

Out of curiosity I did a search for any mileages on Morris Minors. I'm sure there are more, but this is one...

"I had a1968 A35 van until March this when I sold it to buy my Morris Minor van and the A35 had done 369000 miles on the same engine,clutch and gearbox.and never broke down.The A35 was by owned by my brother-in-laws uncle since it was 6 months old until 1996 when I got it.It had done 342000 miles between the end of 1968 and 1980 when he took it of the road and laid it up in a shed intil I got it in 1996.It had been off the road 16 years and I just put a battery on it and cleaned the fuel pump and it started.I just replaced the brake cylinders and it passed the MOT first time for over 16 years."

You can buy a plug in diagnostic tool on ebay for about a tenner, they will tell you what the problem is, you then have to reset it so as the engine light goes out. It all depends on how computerised your car is, my old Renault was a nightmare for warning lights, the lights would come on if I had a tyre changed, I think that car was more self aware than I am.

Be careful with the diagnostic tool, but we have 4 to cover different makes. One was £125 off Ebay, the other was £7,500 from Lucas electronics.

Also, switching off the light does not necessarily rectify the problem, otherwise the light just will keep coming back on. It can be a very expensive part changing process if you don't know the code.


My ex and I bought a brand new Citroen and it ran annoyingly very erratic. We took it back to the dealer under warranty and they said their equipment showed no fault. It was horrible to drive as I am quite sensitive to that kind of thing.


Anyway, by sheer coincidence, we decided to buy what was then the latest diagnostic tool and we / well, he, decided to test the equipment on the brand new car. He came rushing in the house really excited saying he had found a fault on the brand new Citroen. Our new equipment had a facility of recording a couple seconds of the fault and could play it back.


We went back to Citroen and explained why we had the equipment and showed the service manager the playback of the fault, and why the engine was having a varying tickover on occasion. What did he say?


He said the fault did not exist as Citroen's own equipment could not replicate the fault and they would not do anything.

If the light stays on, it is most definitely an MOT failure without a doubt. I won't be leaving it that long.

It will go to a garage as soon as I can find one that is open. Tomorrow morning hopefully.

At best, the emissions are likely to be illegal and police are out in force in this town atm, doing spot checks on all kinds of things, including looking for DD. It says a lot about where I live. They nicked less people for being positive for DD than they did for having stashes of drugs in the car.

I am having problems with a light coming on at the moment too, but it goes off as soon as the engine is warm, if I restart the car. I have a Vauxhall Astra Tourer. Garage tell me its quite a common thing in cold weather. ???

Some lights come on and stay on even if the initial problem goes away.

If your problem is a sensor part of the fuel-air mixture control then there may be an unwanted side-effect of damage to the catalytic converter. Replacement converters are expensive, so don't drive any more than you need before you can get the sensor (if that's the problem) fixed.

ah, you get a flashing light for that one, SQL. According to the handbook.
No, worry not, it is going to the garage first thing tomorrow.

Always with these lights - you have to ensure car main battery is fully charged (overnight charge should do it/cables disconnected)

Battery voltage drops in the cold weather anyway - and lots of short trips can be a net drain on the battery - and EVEN IF CAR STARTS that does not mean battery voltage is enough to properly power the electronic modules.


The QUICK TRICK - is to do a HARD RESET - that simply is disconnect main battery cables (NEGATIVE off first and reconnected last)

Then HOLD BARE END OF CABLES TOGETHER for say 1 or 2 mins - this enables the micro capacitors in the various modules to drain all stored power - and on reconnection to main battery they reset back to normal (hopefully).

MAKE SURE YOU HAVE RADIO CODE BEFORE DISCONNECTING BATTERY - though you can get it from main dealer by quoting Reg No etc.

Finally - yes you can use any good CODE READER to check these faults - a good one is maybe £50/£75 online

Check handbook for location of OBD plug - looks like the old scart plugs - usually below steering column

You need to regularly recharge main car battery - do it overnight - especially if doing lots of short trips which can be a net drain on battery

Took to the garage this morning and he ran the diagnostic tool. Came up as intermittent fault, due to either faulty sensor or manifold inlet. He reset the sensor and said wait and see if it comes back. Will have to book it in if it happens again.
Had to laugh when I got in the car and started the old girl up. The engine light went straight out and did not get the warning on the computer either, having got the warning for the last 3 or 4 days continuously.
Anyway, he also topped up fluids and replaced a side light bulb and then didn't want any money.
