PLEASE someone that knows these engines give me some idea what could be causing this annoying problem, i am heavily in debt now and whilst the car is reliable and driving well we still have this hiccup and its got no engine warning lights up so what are your suggestions please x

To be honest it could be one on a hundred things, but without more info, there's no way of helping, without suggesting things at random.

The first thing to do is to have the fault codes read, and then tell us what they say!

I have a 2.2 tdci st and it felt like it was surging and when you nailed it in 4th,5th and 6th it felt like the power was coming and going,I put 20k boost straight into the turbo and fuel system cleaner and it's pulling fine now with no surging.
Funny thing was I was getting 48mpg after I serviced it then changed the tyres for new uniroyals and I'm getting 43mpg????

I bet you have a split EGR hose......................

If she has, I have just the solution!

monica

Thankyou for taking the time to read and reply to my post, much appriciated, and Cosnada if it were a split hose it would have shown up in the smoke test last saturday .also when the car was plugged into machine it showed no faults which im led to believe can happen if warning light hasnt come on then problem /fault isnt severe enough for machine to detect, i have put fuel cleaner through it a few times, its so damn annoying, but i thankyou all for reading my post and giving me your thoughts to what to try, i shall let you know if i do eventually sort it

If it's a 2002 car no faults with either the turbo, or EGR will flag up as they're controlled by vacuum, rather than electronics. Later Mondeos had electric turbo actuators, and EGR control.

It could still be EGR related, especially as it's occurring around 2000rpm. Even if the EGR is fine, it 'could' be the EGR solenoid operating incorrectly.

The cheapest, most sensible next step (if there are no fault codes) would be to blank off the EGR valve with one of these to see if it makes a difference.

Such a shame these cars have so many fuelling issues,I drove my mates one up from Wales 3 weeks ago and it's a pleasure on the motorway but I just couldn't live with the thought it could break at anytime and cost ŁŁŁŁ's to put right.
Hope this gets sorted,I remember your previous posts and this has been a shitter to you lately.

monica

Thanks you guys, yes this car has been a sick note that has cost me far more than car is worth and thanks DanW@FastFord ill def look into trying your sugestion but can blanking off cause furthur probs to other parts of engine ? as thats the last thing i need lol i drove 500 miles this weekend ran great other than around the 1 1/2 - 2000 rev mark soo frustrating !!! i even had to stop and put old air mass meter back on as 3rd second hand one was showing some really erratic fuel comsuption on digital reader ?

monica

Thanks Vaughant i too hope it gets sorted, no chance of me selling and buying anything else as its put me in soo much debt got to keep and drive it till its finished - hopefully a few years but not looking too promising lol , it is a shame i love my mondeos but this model has put me right off ever having another

I've blanked the egr off of my mk3 diesel mondeo and it definately accelerates more smoothly.

Blanking off the EGR won't cause any issues as long as your car is a Euro3. You can tell because it won't have any electrical wires going to the EGR. If it does have an electrical connection it will bring on the EML but that in itself won't cause any issues.

monica

Thanks so much Dan@fastford, i will deff be asking garage to look into this, will blanking off cause bad emissions at mot ? and it wont cause other problems long term to engine ?

monica

Thanks for info Richie

monica

popped into garage yesterday and one of the guys pulled a thin rubber hose off nr side at front of engine ? bunged end of hose up with a bolt/screw as a tempory test and said its a quick way to blank off so see if it makes difference, so drove home after work and still surging !!! grrrr does this poss mean its not the egr, egr valve or egr solonoid ?

powley31

have you had the turbo checked?

monica

Hi Powley no the turbo hasnt been checked but according to lots of forum reading the turbo apparently doesnt get bad it either works or doesnt ? i have no idea if this is true ??? but one thing we have found is the pipe that leads to one solonoid my mechanic sucked it and it appears faulty so either split in the pipe or perhaps the solonoid ? only confusing thing is when pipe was removed like a tempory blank off, the car drove no different so perhaps that was wishful thinking

powley31

Not always the case, if the turbo has intermittent fault, it may play up and surge/judder, I have recently fitted two turbo's one on an Audi and one on a VW both of which had no fault codes but hesitated, worth getting it checked.

monica

Thankyou very much powley31 i will get it investigated, blooming hope turbo isnt faulty as well !! this car has been a money pitt !

It's not really the same as blanking it off. If it's stuck open it will still cause issues even with the hose bunged up. You ideally need to get it blanked. It's cheap and easy.

Turbos rarely fail intermittently on these. It generally is either working, or not working. Especially on the older none electrical ones like you'll have.
