Tdi Loss Of Power (again) - Resettable

[trumpettrouserspablo]

Sorry first posting so not sure how to add something but here goes!

 

Hi can someone help me please

I own a Ford Galaxy mark 2 2002 plate 1-9 tdi 115 bhp starting is fine first gear fine and pulls well until i go for second gear the revs drop to around 1200-13oo ish and will not pull until the

Revs return at about 1900 then the turbo seems to come-in on full power. Anything above 2000 revs the car seems to run absolutely fine ie, on motorway driving or fast flowing roads. Tricky manoevres, parking, stop starting and town driving can be a nightmare. At low revs keeps on stalling if revs aren

Help!

 

I have a 2001 (65k miles) 1.9TDi (115 BHP) that developed an interesting (and ALARMING) problem last week whilst towing a caravan. After about an hour of "hard" driving the car suddenly "lost power" and would struggle to hold 35-40 mph (VERY embarassing on the motorway) - up to that point it had quite happily towed at 55-60 mph. There were no warning indications or anything that alerted to a problem (engine temp OK, etc). I limped into a Service Station, waited 30 mins and set off - all was OK with no reoccurrence for the remainder of the journey and for the rest of that week (not towing). On the return journey towing the caravan it happened again after 45 mins - after a 10 minute wait on the hard shoulder I set off again and it was OK for another hour. This time when it went again, I came to a halt on the hard shoulder, switched off and immediately restarted - engine back to full power! No problems for the remainder of the journey (approx 1 hr).

 

Reading the TIS I note that the turbocharger's vanes have an emergency position (maximum opening cross-section) to obviate engine damage due to execessive boost in the event of a turbocharger control "concern" (eg "in the event of an electrical concern or leak in the vacuum system"). It seems most probable that this was what was happening with the PCM putting the turbocharger into a latched "safety mode". Question is, what is tripping the PCM?

 

I persuaded my local (and very friendly non-Ford) garage to have a play with their SNAP-ON diagnostics kit and it came up with code "17965 - Turbo Pressure Control - Limit Exceeded - Occurs Intermittent". This appears to validate the latching of the emergency limp home mode. Question is what is the probable cause? The SNAP-ON diagnostics do not give any further clues. Outwith of the actual turbocharger the control system appears to be very simple: the PCM controls the Vane Adjustment Solenoid Valve which regulates a vacuum across the vacuum diaphragm unit. Given the car drives OK normally, it is not a vacuum issue and the range of actuator movement appears OK. My thoughts are turning to inputs to the PCM that would cause it to trip the turbocharger. I'm aware that operation of the brake lights will trip out the turbocharger (boost not required during braking) but this is not the problem (this is not even mentioned in the turbocharger section of the TIS). Has anyone had a similar fault and satisfactorily cured it? Does anyone know what other "sensors" might persuade the PCM to "trip" the turbocharger?

 

I am very hesitant in taking this to my local Ford garage who have a poor track record in my eyes - the options here (turbocharger change, PCM change, etc) are all horrendous and with WDS hook-up starting at

Hello - this is my first post, but hopefully a useful one to anyone else having an intermittant loss of power from their Galaxy. I have a Y/2000 Galaxy, 1.9TDI 115. I recently bought the car from a dealer with 105k miles on the clock. When I test drove it the dealer informed me that the Air Mass Meter needed replacing and that he would change it if I bought the car - the symptons were intermittant loss of power. For the first week after buying the car it seemed fine, albeit a bit juddery at times, however it started playing up after a week or so. The dealer took the car back and replaced the Air Mass Meter again, and again it seemed OK for a week or so and then played up again. Switching the engine off and then on again seems to solve the problem, but it eventually came back every time.

 

This time, with the dealers agreement, I took the car to a local garage and they diagnosed the fault as being "excessive boost pressure" in the turbo. Initially I was asking the dealer to replace the turbo, but then I found a company near Huddersfield called "A R Turbo" who as well as supplying standard Ford Turbos can also repair them. For a cost of

Hi guys just new to the forum, could anyone tell me the location, or where i would find the boost valve on my 2004 galaxy?

I had the dreaded problem for the past couple of years until recently.

 

1st Replaced MAF, thought it made a difference for a while but hadn't

2nd Took car to local garage changed N75 sensor, no difference

3rd Took car back to garage few more times, checked hoses all reported OK

4th Gave up for a while

5th Went to new garage as turbo cut out was getting more frequent, checked hoses all OK, changed N75 sensor made slight difference (back to original level of occurrence)

6th Was advised the only option was replace turbo, so bought a recon from essex turbos as garage could not compete on price. Had it shipped to garage & fitted. During fitting they noticed that the oil supply pipe to the turbo was blocked so replaced it.

 

Problem now fixed ;) after time & spending loads .

I suspect it was the blocked oil pipe all along which at
