To Daniel - if you haven't sorted your idle / stalling / self revving problem yet, I suggest you check out the idle stepper motor. It's a common fault on 306's with the 1.8 or 2.0 engines. My old 1.8 had the same problem twice in the 2 years I had it.
You can sometimes get away with cleaning the old one out which will cure the problem for a bit (usually about 6 months), but it will eventually need replacing. Can't remember the cost (it was 3 yrs ago) but it wasn't ridiculous.
The big problem with this failure with regard to getting it fixed is that it doesn't usually trigger a fault code in the ECU. This confuses the hell out of the average fitter in the Peugeot dealer. I say fitter because the ones in my local dealer cannot be called mechanics or technicians. Your £65 + VAT "diagnostic" session consists of a YTS kid plugging the fault code reader in, and if that doesn't tell him exactly what needs doing, he shrugs his shoulders and gives you the car back still playing up. I had that four times. The fifth time, their service manager diagnosed it over the phone and it was fixed while I waited! Work that one out?!
Hope this helps mate.

Having the same trouble with the engine idling erratically and general loss of response in the engine. Have tried all else, will definately get the idle stepper motor looked at now though.
Cheers and good luck with the pocket rocket.

Had niggling idle/starting faults with my 306. Often used to take a good thirty minutes before the engine felt warmed up. Like most people I just started the car as soon as I got in. I was tipped off to turn the ignition on and wait 5 seconds or so before turning the key further to start the engine. Funny enough this is how I have to start my diesel. When I wait the five seconds I can hear the fuel pump behind me pumping the pressure up in the fuel injection system. It seems that if you set off straight away the system is charged which upsets the engine management system. Don't know for sure if this is true, but it runs sweet when I delay the start.
Anyway, an excellent car which has "long legs" for the motorway and handles well above its price.

HI all, I am Maltese and own a 306 Estate 1.4 multipoint fuel injection, which I reckon is known in the UK as Meridian? I have the same incurable erratic idling syndrome bunny-hopping phobia! Have heard it's to do with the Sagem coilpack creating a voltage spike to the Sagem ECU and damaging it! Revs to 5000revs on cold start, then plays between 2000 to 3000revs and never goes below 1100! What a shocking car to own!
Changed stepper motor, had all wiring harness and sensors checked at a professional garage, but all to no avail. sounds like ECU might need replacing..?? But what caused it to blow in the first case? Peugeot dealership in Malta are totalled and lost! Believe me, yes lost!! Any ideas..!!! All your help much appreciated. Thanks to all!

Does anyone know where I could buy a rear ABS sensor for my 306 1.9 diesel cheaply?

I have a 306 Peugeot 1.9 diesel. I put the key in the ignition, put my code in, and turn the engine over. It just turns over and does not start. Has anyone got any suggestions please?

It seems that wherever you go, Peugeot owners have the same problem. The dealers do not understand the cars, and lack even the most basic electronic diagnostics skills.
An ECU is inherently reliable. It's a box of solid state electronics which are sheltered and shielded from the elements. Electronics rarely fail unless damaged or short circuited. Think about it - you almost certainly replaced your last computer because it was outdated, not because it stopped working. Your last CD or DVD player died because of a mechanical fault with the laser pickup or drive system than the electronics that ran it. On the rare occasion it does fail, it can be opened up and repaired with components available from your nearest RS or Maplin store.
In fact, I can only think of one engine management fault caused by an ECU of all the cars I've worked on in the last year, and that car had been suffering from a rainwater leak which had soaked the ECU box. Replacing this most expensive of components at your cost with only a guess that it's going to fix the problem is inexcusable.
These dealers need to be stripped of their franchises and reported to Trading Standards. What they are doing constitutes theft.

Dear Sir,
My Peugeot 306 - 2001 /1.6, on the way to work in the morning or when it's cold (I mean overnight, no snow or freezing cold), I start my car and it starts for about 5 seconds and shuts off. I restart it again for 3 seconds, and when I'm pressing the fuel pedal, the engine RPM goes up to 2000 RPM or higher, and shuts off again!! This is happening about 3 or 4 times when I start the car!
I used some carb cleaner spray inside the air filter house to help me get started, and finally started by using the spray!
I need urgent help with this problem. I have checked, and the spark plugs are good, the fuel pump is good (6 bar pressure), fuel injectors are good as well, crankshaft sensor is good, MAF sensor is good, air filters and fuel filter are all good and new. Idling sensor, I don't know if it's that where the problems come from!!
Please help. Email me on qahtan.kahalf@gmail.com
Regards.

Good idea to change the oil more frequently than the service interval, that's only there to keep fleet managers happy, I don't believe in letting Diesels do more than 10,000 miles between oil changes it just shortens the life of a perfectly good unit.
