Anti Pollution Warning and Limp Mode Advice

ChellyD86

Looking for some advice on my Peugeot 207 1.4 petrol car.

Approximately 4 weeks ago my car cut out and although it would start it would cut out when pressing on gas pedal. Got it taken to a garage who had it 3 weeks and eventually fitted a new ECU.

Got it back and 2 days later anti pollution faulty warning light came on and car would be stuttering at times but then would drive fine. Took it back to garage who said no issues showing and cleared warning light. Light came back on following day but car seemed to drive fine. Yesterday car cut out and again would cut off when pressing gas pedal. Left it all day yesterday and tried again today and car started and drove fine with it slowly slightly in limp mode but then drove fine.

Taking it back to garage tomorrow but losing faith with them. Any ideas?

crank/cam position sensor, had this fault with pug 307 1.6 16v. everytime anti pollution threw up the crank sensor was at fault, these pugs can go through 1 per year.

How much did garage charge you? 3 weeks and they just ended up chnging the ecu, guess they couldnt be bothered to check properly and just went by some fault code rather than finding out what actually caused it.

Thank you both for your responses!

I paid £270 for the ECU it did fix it for a wee bit but was still stuttering and then cut off again on Saturday where I couldn't drive it at all. Managed to drive it home today, I'll mention the crank/cam sensor to them tomorrow. Are those expensive to replace? I'm hoping to not pay anymore anyway cause surely that should have been picked up on in the first place.

Would that cause the car to not accelerate and also when it does drive go through quite a lot of fuel? I did mention this to the garage when I took it back second time but obv something they didn't want to deal with.

Cut your loses and try a different garage. Where located someone on here might know a decent local.

I'm in Airdrie, Lanarkshire it's just outside of Glasgow.

faulty crank sensor can give loss of power, excessive fuel consumption, rough idle incl hunting or surging, stalling excessive rotation of the engine in order to start off the key.


crank sensor Error code normally doesn't show up on a cheap fault code reader its a dealer specific fault code.


crank sensors are easy to fit (literally 2 bolts to undo one) not expensive.


cranks sensor is where I would start knowing the pug 307 my dad owned, if not careful you can damage the or fill up cat converter driving it with excessive fuel consumption and damage O2 sensor pre cat and also heat up the exhaust manifold when the cat is blocked and cause it to fracture and these error codes can follow shortly after a crank sensor has failed to be diagnosed.

Thanks so much for this. What you said in the first sentence pretty much sums up what is happening with my car. I'm about to phone the garage just now as I took it to them first thing and they weren't opened so they're being told to look at this first and also to try and fix it once and for all. I don't want to be paying anymore for any other damages that really should have been fixed in the first place.

Thanks again!

Just an update!

Well garage have said machine showing 2 faults relating to sensors and exhaust overheating. They've ordered part which should fix both faults and should be done today, £85 for sensor.

Exhaust overheating..?

I would personally be asking them what they're intending to do about the ECU you've already paid for and which almost certainly was unnecessary.


Is this a main dealer by any chance? Typical 'can't be bothered to diagnose' approach involving fitting a series of parts which *could* cause an issue, starting with the most expensive and working down the list to the 5p washer or fuse which will ultimately fix it, all the while relying on the 'ah, this fault will have been caused by the failure of the previous component but we wouldn't see it until that one was fixed' excuse.
