EGR Valve issues?

[sooly]

HI Guys and Girls,
I've developed an acceleration lag in my puma in between 1800 - 2200 revs, in all gears but is most noticable in 2nd and 3rd. I think Scallops had a similar issue about a month ago. I have been to the dealer who reset an engine sensor which did nothing. Has anyone else had this issue and had it repaired? If so what was it so I can return to the dealership with some knowledge of the issue?
Thanks

Mate I've had it too. Have already had one replaced last week, but new one seems to have the same issue ! Is generating OBD fault code P0404.

Am driving it down to Melbourne next Monday so will see if that 'clears out the pipes' but have already booked it in for a second look at it when I get back

Given some of the feedback on Defender2.Net it seems the only reliable long term fix is to blank it off - something I don't really want to do esp while under warranty.

Hi Gav
thanks for the reply. Doesn't sound good. I talked to a mechanic mate of mine and he said if it's blanked off it will transmit a constant error code as it won't be detected by the ECU. I wonder if a fuel additive would clear the crap?

No mate - you can get around that with one of the blanking kits made by the UK guys - which leaves just enough opening to avoid triggering the sensor.

Check out: Defender2 - View topic - Accelerating...

As for fuel additives - I spent $60 on 2 bottles of the strongest stuff I could find and it did nothing beyond give a short term octane boost.

Anyone locally fitted an EGR blanker?

It must be a very variable thing...I'm at 40,000 km and 2 years without issue.



Mostly city driving at 60km per day but with some freeway stuff and off road mixed in.

There's clearly a **** batch of EGRs floating around hence why some are OK and some are cack, and I (joy of joy) have had 2 in a row... Same thing as the clutches, gearboxes and other notable examples of LR's appalling component quality. Gee I wish I'd bought a vehicle from a company which has been making drive trains based around the same basic body shape for 60 years - oh that's right, I did....

I have had a faulty EGR for almost 12 months now. I'm awaiting a new one to be fitted. I haven't experienced any lag as described and the Pumas done over 49,000km now.

I can't recommend enough putting silicon hoses on the Puma to smooth out acceleration. The difference is considerable as the intercooler hoses are so soft they expand under boost.

G'day sooly,just get rid of the egr valve,easy to do and there are many kits to choose from,did mine about a month ago (03 disco) and its a different car to drive and better on fuel!!Plenty of info on these forums,if your getting a driver demand fault code,its probably the pedal,also did mine and made a big difference,cheers!

Oh the joy of a TD5. Not so easy on a Puma unfortunately, I wish. ECU doesn't like people fiddling. I know lots of people are trying in the UK but haven't heard if very successful without reprogram ECT.

Mine has been doing the same since i got it and no matter how many times I mention it to my stealership they always say the same... no fault detected. I will now go armed with the info in this thread and get the stupid thing fixed. Thank god for forums like this?
