Hi guys need advice,

Brought a 2001 tddi 2.0 Mondeo Zetec the other day more as a project.

My turbo doesn't seem to kick in at all and the car seems really sluggish.

I am driving with my foot down and feels I'm driving a 1.0 engine in my big car. There is nothing at all it just goes up slowly. There is no misfiring or anything.

The car was used on a farm and have fixed the oil pressure switch and the rear wheel bearing hub will be doing a service On the car next week but this is my next mission.

Any ideas welcome please

If it was me. Check the air line between turbo and actuator. Clean out all the intercooler pipes and inlet manifold (inlet manifold removal requires exhuast manifold removal)

A stock one is slow off the line/ through the gears and in 1st and 2nd, there is no point in revving it past 3.5k (power/torqueband is usually about 2k-3.5k) and it is quite a big heavy car (depends what you are used to- if you owned a moped before you would think it was quick, if you had a 400Hp evo you would think it was broken!) in 3rd and 4th it should pull well and can be deceptively quick (because of the engines "torquy" low revving nature)

 

The TDDI can have a fixed vane or variable- vane turbo - they have different power delivery characteristricts

 

 The inlet manifold is at the front , the exhaust at the back, you can remove one without having to remove the other

 

If its not performing like is should there could be a whole load of reasons - do you intend to keep it stock?

I would give it a bit of a service 1st, like a fresh air filter, and who knows when the oil was last changed, then get a solid blanking plate on the EGR, clean out the inlet manifold and the intercooler, check the boost hoses for splits/ leaks (sounds you could be low on boost)

 

if you could post up some pictures to see if you have a fixed or VNT and front or rear EGR

VNT = Variable Nozzle Turbo/ variable vane turbo

 

if you have a VNT (rather than fixed-vane) it can be another potential source if trouble, as the VNT mech can get coked up, causing it to sieze or jam, which can cause low boost or exessive boost

 

if you have a rear EGR one (solid) blanking plate will do, it fits after the EGR valve.  

 

its debateable whether engine oli flush is nessesary - the main thing is fitting a fresh oil filter and the right oil, and not leave the old oil in for too long - after a while oil looses its protective qualities    

 

the manifold can get badly clogged up, (much worse than the intercooler) spraying EGR cleaner into it is a waste of time, you have to take it right off the engine, the best way i found to clean it is with a hot, high pressure foam/ soap jet- wash.(ie- industrial) and a de- greasant - its a dirty, messy job

its the long plastic thing at the front of the engine, you simply unbolt it, it is easy, try not to loose the rubber gaskets and it does not need a lot of torque to replace it  

 

The mk3 diesels (TDDIs/ TDCIs) do not have flaps, that is the petrol- engined Mondeos, so no, you won't need (non-existent) flaps  

 

You get the blanking plates online (eg - ebay) best to use solid, stainless steel plates, especially on a rear EGR engine, (plate gets hotter) as aluminium ones can melt
