Is The Code Reader Wrong?

[Johndouglas]

First a thank you to Coastline for his 'messages' help. My C5 HDI has become difficult to start from cold. I've used my code reader on it and it came up with P0113 and P0102. The 113 code is the air intake sensor and the 102, the MAF. The MAF was cleared because it wasn't plugged in properly and the local dealer has supplied me with a new AIT sensor. That's the rear one in my picture. Anybody tell me what the front one is? Having now cleared the codes and the reader telling me that it has no codes, cold starting isn't any better. Any suggestions.

Could possibly be map sensor(manifold air pressure) but realy need your enginge code (in the windscreen bottom right corner) to tell you.

What are the symptoms of the starting is it just crankinig over and over then fires up what colour smoke comes out or does is turn over and gradually fires up till its running again what colour smoke

[Johndouglas]

but realy need your enginge code

 

 

Engine code is RERHRH. Gradually starts after a long crank. Haven't really noticed any smoke. Warm/hot start is almost normal. Also there's no fast idle tick-over when it's cold.

 

Still puzzled by the other sensor in my picture. My French manual describes it as "an air pressure sensor", although the MAF is in the pipe in front of the air filter. It has three pins. It doesn't show as a fault on the reader. Is it possible to test it?

Bit confused with your engine code. At the bottom of the windscreen theres a panel made up of 2 lines of numbers and letters. On the top line youl see numbers from left to right in the middle there is 3 letters and that is your engine number

[coastline taxis]

Sorry my mistake its only 1 line and the first 3 letters you see are your engine code

Bit confused with your engine code.

 

You can say that again!

Our Xsara's VIN is VF7N1RHYB7******* and the engine is a RHY.

The C5's VIN is VF7RERHRH7******* so does that make the engine a RHR

Poor cold starting but normal when hot could be the glow plugs need replacing.

[coastline taxis]

best if you pu the whole number on hear

[techbod]

im going for new glow plugs £40 but check if there is an air leak as this will require pressurising and that the problem, when you crank the engine and no fuel pressure it has to pump it up then it starts that means an air leak

[iannez]

glow plugs on a hdi will only be used if the outside temp is lower than -5. you need it on a tool that reads live data to see what pressure you have at the fuel rail and what the engine speed is when cranking from cold. if the ecu is not seeing enough pressure or high enough rpm it will stop the car from starting. had a nightmare with one of these a few year ago. finally traced it to a tired starter motor. sounded fine when cranking but engine speed was just below the set value to start the car.

[mlkey]

Glow plugs are not used until zero degrees, and then for only 0.5 of a second. As the previous post said, -5 is where they start to work for any considerable time. Save you money and look at other areas, fuel delivery, compression etc.

The good news is that my C5 is back on the top line. The bad news is that it's taken so long to track down the trouble. I eventually booked the car into a Bosch service depot. They kept it overnight but after the second day although their computer showed three codes, they couldn't tell me what was wrong with it. I took it away and booked it in with the local Cit. dealer. At first they wanted to charge me £120 for a new battery. They said mine was the wrong size. What I have fitted is a Bosch 096/100 70Ah 420/720 - and only six months old. Fortunately I was able to take them the original Fulman fairly fully charged. After swopping them over and trying again, they decided the starter was turning over too slowly. A change of starter motor and this morning's cold start shows the car's back to normal. So first prize to iannez for his correct diagnosis.

 

If you're wondering why I changed a perfectly good battery six months ago, it was because the cranking speed seemed to be so slow that I thought the battery was on it's last legs. In fact, ever since I got the car I've always thought the starter wasn't as energetic as our other three. With the benefit of hindsight, I should have got it looked at when it was still under warranty.

Good result! Mine is a little slow :unsure: Will remember this one for if it decides to have cold start issues!

 

Thanks for feedback :lol:

[techbod]

the codes would have been nice

[mlkey]

Having now cleared the codes and the reader telling me that it has no codes, cold starting isn't any better. Any suggestions.

 

There ya go Techbod..
