New Post Total Loss Of Power

[Guest allsopp89]

Hello, sorry to post a seprate topic only I am getting desprate. As mentioned car is booked in with Fords on Tueday and I am dying to find fault before they charge me an arm and a leg.

 

Just a quick question, before we got the new air flow meter and had the diagnostic done the car was not recognising when we unplugged the air flow meter, so we unplugged it and drove without, it made no difference what so ever driving without as it did, but surley if it was not the air flow meter problem, then when we unplugged it, there should have been two problems, (the existing problem and the air flow problem) but no. Now that we have changed the part and it is still no different we have been told by a Ford Mec, that it could be that the on board computer has not recognised that there is a new part and that it needs re-coading.

 

would be grateful for any advise.

 

Thanks Cheryl

 

PS I am pig sick of this car now

Sounds like nonsence to me, I have never heard of having to reset the ECU for a new AFM.

 

Where abouts are you based? Some members have VAG-COM and may be able to help.

If the airflow meter is not making any difference then there's something wrong with the airflow meter, wiring or ecu. Usually, especially on diesels, if the airflow meter is u/s unplugging it improves the performance. It's possible you may have issues with blocked cat or egr stuck open which will give similar problems.

See the copper/silver pipes on the manifold? well they are the pipes for the ERG system, see the valve on the right? above the heat shielded ac pipe? thats the air injection valve from the secondary air pump, if you follow the pipes around to the rear of the engine you will find that its linked into the intake manifold and the ERG valve IIRC

[Guest allsopp89]

thanks for the pic. but our engine has no copper pipes there, but we have the same layout :)

[Guest allsopp89]

hi i,ve removed the heat sheild and there is one copper pipe under the manifold which goes round to the back of the engine, and enters a plastic box which is linked to the afm. hope you can help :)

I believe this is the EGR valve,,,,,as vr6174bhp told you

I had a similar problem with my 2.3. In the end, and got I the answer from this site, I checked the plug connecting the Lamda sensor to the rest of the loom.

Find the Lamda on your exhaust, you can see it through a cut out in the pan under the engine, trace the wire back up towards the front of the vehicle for about a foot. You'll see a black plug. Check that the two parts are firmly pushed together, mine weren't !

I'd spent hundreds at Frauds and fitted a new cat, all to no avail, it was simply that the two halves of the plug had become slightly seperated.

[Guest allsopp89]

Just to update you. Car is in with Frauds, has been all day. They think I am going mad. They say nothing is wrong but I know there is. They suggested that it goes in for a diagnostic and they will find the fault, dropped car off at 8am, at 2pm they had not touched it, rang back 30 minutes later and they told me that the master tech had been out in it and there is nothing wrong. I asked whether they had done the diagnostic and they said yes, so what they are saying is that within 30 minutes they had diagnosed it and test drove it, so if they think they are charging me an hour they can think again. Anyway, my husband went up, and supprise supprise car was in the car park dispite the service department telling me that they were working on it that minute. Husband and tech went out in and and I am so happy that the car tried to stall twice, otherwise it would not have beleived my husband at all. He has now admitted that it should'nt do that however confirmed that they would have to look at it tomorrow for me now. Just read the post above about the lambda, so I think we will try that - will just have to wait to get car back cos Frauds have still got it. Will see what they say tomorrow. I will keep you all posted and thanks for all your help.

please please please can anyone tell me where the egr valve is on a petpol engine. i have been told it is behined the battrey box :lol:

[Guest allsopp89]

Desprate for some advise please. Pulled car out of Frauds today coz they were not doing nothing and had the car for two days, luckly I put them in their place and they did'nt charge me, however tonight I have unplugged the intake Air Temperature sensor, and for some besare reason the drowning noise and gone and it is pulling like a new car - fantastic? or is it?, ok I could get a new part, but is it just working better because it is getting information from somewhere else, I am not sure. Furthermore I am not sure what problems it is going to cause if I was to drive without it unplugged. Supposed to be going away tomorrow in Caravan and I just hope to god that it will be ok. Please if you have any advise let me know.

 

Thanks

Where is the "intake air temperature sensor" you mention? In the pipe from the air filter? If so then that is the MAF. And if it is the MAF then the best way to test it is to unplug it and see if the car runs better without it!

[Bigjeeze]

The object circled in white is the MAF - this is what MM thinks you are referring to - If it is then all you need is a new one and the problem should be solved - providing as you say that when disconnected the engine runs fine.

Hi.I recently purchased two MAF,s from Fraud and both were defective.Third time lucky and the car is fine.I think that all fraud do is recomdition them and put them in a new box and sell them as new.

Best of luck
