Full Version: P0299 Obd Error Code
Ford Owners Club - Ford Forums > Welcome to Ford Owners Club > General Ford Related Discussions

Hi my daughter has a ford focus 1.6 tdci 58 plate.


She has been complaining of a lot of black smoke from exhaust when accelerating so i plugged it in to a basic obd 2 scanner connected to my phone using the torque app. I did this originally 2 weeks ago or so  and generated lots of codes which i cleared my thought was id recheck in a couple of weeks to see what came back.


The code there this time was P0299 OBD error code i had a look at this link


I was just wondering if you guys or girls maybe know what to check first or is it worth getting some specific ford software to pin point the problem?


I have looked for split hoses etc air leeks but cant hear or see anything?


If anyone can point me in the right direction i would be grateful it is a pain trying to catch her in though lol.


Thanks Dave.

Hi managed to find the problem I hope massive split in a large hose on right hand side of engine its the one that goes in the throttle housing maf sensor bit I think thats what it called!
Will this be a main dealer part and does anyone know what it called?
Thanks dave.

if your thinking of the part I just replaced, its the Mass Air Flow hose, that goes from the air filter box / MAF sensor, to the turbo and then has a little "7" shape hose, that goes up to the top of the engine block...


If it is, dont bother buying it from the dealer, they want about £90, what you want is one off ebay.


much cheaper and does as good a job!

Thanks for reply it's not that hose!

Its the one on left as you stand looking into engine!

Its the biggest pipe jn diameter it goes into the throttle housing down to the bottom of radiator there is a link bracket the pipe goes through off rad ?

can you take a photo? I am imagining my engine bay and struggling to remember the in laws (he has a similar Focus) I am thinking it may be the intercooler pipe / turbo hose area?

Yeah will do been trying to catch her in lol

Had the pipe off glued and taped it up the car so much better! 

Went the stealership they wanted £82 pound for a new one!

Wouldn't give me part number either!

Does anyone know it? Its a intercooler pipe?

Chuck a photo up :-) and will go from there...

^^^^^^^^^^^^^^^^^^^^^^^^^^  +1


Sorry about post earlier couldn't do it on phone here's the pics








could be the intercooler pipe. is there not a model number printed somewhere (moulded somewhere) into the pipe itself?

Couldn't find a number anywhere!

What's the software ford use at there dealers?

For my bmw just go online think it called real oem and find part through diagrams etc!

Is there anything like that for fords?

One of the guys with the ford software will be able to supply you a part number.

It is the hose between the intercooler and inlet manifold.

Have you checked the likes of ebay?
