Transit connect 2004 tddi lack of power

[Marty.H]

I have recently bought a transit connect and the power does not seem right to me it was not a bad price so don't mind spending some time and money on it.

The van has done 62000 miles the history is a bit vague but its proven at 62000 miles from all the MOT history and the HPI.

The turbo has a slight whine so will possibly need replacing i can feel the van is producing boost but don't seem to have any punch to it:


Im a mechanic and MOT tester for living so what i was planning on doing next is

Full service and all filters

Remove EGR and clean

Clean MAP sensor

Scan van with diagnostics to see if any codes present



What else would you guys recommend doing while i'm there


Thanks in advance

Clean MAP sensor ???????

Strange request, being a mechanic I though you would have know what to do on a vehcile with a problem, hope you dont ask your customers for advise when service \ repairing their vehicles

make sure its a ford f/filter,clean maf sensor,decat it,then remap

Yes cleaning map sensors out it was a very common problem on the T16 rover and several other vehicles

I am a very skilled mechanic but im not familiar with the connect having never worked on one only its counterpart the mondeo. Just because im a qualified mechanic does not mean i still don't learn and have to ask questions.

The reason for asking on the owners club is because there may be a common reason for this happening and it would save me time asking instead of going through the motions as i would do with any paying customers that came in. The only thing i ask customers is the symptoms and problems they have been having which aids me to diagnose the problem.

I have found in the many years i have been in the motor trade is the mechanic who is prepared to ask and take advice is the better mechanic then the one who's head is to far up his own arse to swallow some pride and ask and they the ones who often miss diagnose and cost the customer a lot of unnecessary expense and make mistakes.

Thanks to those who have confirmed what i thought would be a good route to go

can i just add to fully clean the egr properly the inlet manifold has to come off as the valve is sort of part of the manifold and to get that off the exhaust manifold has to come off first

Thanks for that what sort of time is involved removing that as i have not looked at the job in hand yet and was planing to fully de-coke the intake as best as i can tomorrow after work


cheers

ford book time is between 2.6 and 3.1 hours for removal and refit without cleaning

Thanks for taking time to reply looks like it will make more sense for me to get another manifold and prep that and then just swap them over.

Can the EGR system on these be capped off without causing a MIL light to come on or do they have a hissy fit


cheers

i dont honestly know as mine is still running it all connected, although members on here have without problems i think

Thanks ill have a poke around the forum

I think they can be run without fault codes. A solid blank is used for TDDI and for TDCI there is a hole drilled in it to stop the fault codes flashing up.
The egr can't be removed from the ECU programming on a connect though Martyn/VanTuner told me that

seems strange the code cannot be removed on the Evo's we use to alter the hex code to remove the re-serc system on them and it would take it out of the system maybe ford has that well and truly sown up in the Rom so it cannot be accessed or easily found maybe the rom on the fords is not easily indexed having not had much to do with Ford ECU;s i don't know

Im sorry I offended you, would a dirty MAP sensor not flag a fault code, you could also have a look on your scan tool at the live data or scope it to see if the MAP is doing its job and check boost pressure at the same time. I belive the TDDI uses a VP30 or VP44 pump so maybe it could be a problem with the fuel quantity solenoid valve or injection advance solenoid, then there's the accelerator pedal position sensor + a few other engine sensors, EGR position sensor, again all them can be checked with your scan tool in live data or your scope, then the injectors, spay pattern or nozzle opening pressure, it could of had bad fuel or water in the fuel at some stage, blocked cat (if fitted) exhaust, blocked\swarf in filters, cam timing out, as you say you are a skilled mechanic so your going the correct way by checking the basics 1st

[Marty.H]

Thanks for the reply. No offence was taken.

Ill give the van a good service tomorrow and change all the filters and then get the diagnostics on it and data log some data to see if I can see any abnormalities , spikes or readings that don't seem correct.


Ill report back on any findings

Cheers
