| Discovery 3 EGR or HPFP problem? Help needed |
|
Hi guys. Trying desperately to sort out long standing problems and any assistance before it costs me a fortune would be greatly appreciated.
I have a 2007 TDV6 auto with 83k miles. About 6 months ago I started to get an intermittent fault code big F on dashboard, park brake fault and go into limp mode. Restart engine and all clears. This fault now occurs more regular but only on journeys over 20 miles. Never occurs on short trips. Diagnosis from local LR independent garage is low fuel rail pressure and main suspicion is the high pressure fuel pump although no brass filings have been seen in the fuel filter.
However, whenever it is really cold weather, initially when starting off there is no power when accelerating but when it reaches 2500 revs all is fine. This only occurs in winter and is fine after a couple of minutes . This I believe is a symptom of the EGR valves failing.
So my question is could both the EGR and the high pressure fuel pump have failed or could the EGR valves also be causing both issues????????
Really need to get this sorted asap.
Thanks for any replies.

You need your codes read, the symptoms you describe are consistent with fuel problems and EGR but without codes it's hard to pin down. If your car is a keeper it might be worth considering your own IIDTool? Worth twice it's weight in gold IMHO.. -------------------------------------------------------------------

Thanks for your reply. Initially LR dealer did a diagnosis for free as I argued that there was a recall in 2009 for exactly the same High Pressure Fuel Pump issue for 2007 vehicles. They initially said they may contribute but finally declined saying my VIN number was outside the range. Upon looking at recall notices on the internet its hard to understand because of the way they are printed i.e. recall for SALLAAA137A412125 to SALLAAA177A424188 and then SALLAAA137A435285 to SALLAAA178A450620. Mine is SALLAAA137A4349** so at this time Ive had to accept this as no recall shows on their systems for my vehicle.
They also said both EGR valves are not maintaining a steady pattern.
Just sees a coincidence that both failed at the same time and was hoping that the EGR valves could hopefully explain both symptoms.
The engine runs fine all year round except if left for a day or so in winter and only affects the initial acceleration performance for the first couple of minutes.
So at this time looking like a new HPFP and EGRs at a later date.
Can EGRs on a 2007 Discovery be blanked and remapped to save on costs and if so is there anywhere near Manchester to do it?
Many thanks

Hello Garbo500,
have you found the cause? My car has the same failure, except that the EGR were changed 2 years ago, so I would expect that they are not the problem...

Hi Junds.
Both LR Dealer and Independant LR specialist diagnosed HPFP failure.
As I have been sticking to short journeys it hasn't faulted for the last few months until last week, so I will post the latest fault code for any more suggestions but am resigned that its going to cost me a grand for a new fuel pump.
Although the slow acceleration when cold appears to be the EGR's it's not a major problem and doesn't cause any warning lights to activtate at the moment, so will reassess next year if I am going to keep it.
Hope this helps and I will post the latest codes this weekend so you can compare.

The fault codes are as follows;
P2290-00 (6 8 ) Unknown which I think will be the HPFP.
PO45D-00 (6C) Exhaust gas which I believe relates to the EGR valves which are sticking only when cold for a few minutes until the engine warms up
The car struggled to start this morning. First time in 6 years so the following faults also flagged up:
B1D29-93(2E) No start, even
U1A44-6C(2E) Fuel Level
B1B70-81 Body Control circuit 2
P0489-00 (6C) Circuit low
U0100-87 (A8 ) Control Module
So at the moment it looks like a new HPFP. This has only faulted once in the past 2 months as I have stuck to short journeys.
The EGR valves might have to wait and will reassess when the weather warms up if I`m going to keep the car.
Hope this helps.

Big thanks to Narpy.
Ive been battling with Land Rover since August regarding this High Pressure Fuel Pump.
After giving up decided to email Dr Speth, CEO of Jaguar Land Rover direct and within 5 days they agreed to recall the car and fit a new HPFP for free.
Work now completed and symptoms have vanished fingers crossed.

Hi Garbo,
this P2290 and P0087 drives me crazy.
Do you have the e mail to Dr Speith?

Urhunden. His personal email is ralf.speth@jaguarlandrover.com
I see that your car is a 2008 model. Have a look on the internet for recall notices R/2010/147 and R2009/051 faults P008 and P021 which affected thousands of Land Rover Discoveries and Range Rovers.
The HPFP was defective in those vehicles, so they replaced a new pump under the recall.
My car had NO recall notice showing but my VIN number was near to those listed in the recall notices.
I sent a copy of all the notices to Dr Speth complaining that the HPFP was obviously defective in many more vehicles manufactured at that time that were included in the recall.
They examined my car and saw that the HPFP was the same as fault P008, so finally after 3 refusals to replace my HPFP they finally agreed after my email to the CEO.
Hope this helps
Good luck !
