Some good news about my Puma

[Scallops]

Hello Folks,

Unfortunately, over the last period of time, I have had to report on many big issues that I have encountered in my ownership of Grover.

But at last - the sun is shining - I'm feeling optimistic about my truck again. Since my new transfer case, gearbox and clutch have been fitted and run in, everything feels rock solid - much better than as it was from new.

Couple this with my engine management light issue, which, was in fact the EGR valve. Since this has been replaced, the truck drives just so much better that it's hard to believe. One example is this - at about 60km/h in 4th, hovering on and off the throttle, the truck could produce a very "jolty", kind of surge feel. LR initially insisted this was driveline slop - I knew it wasn't (it had never done so previously), but had resigned myself to this not being able to be fixed. And, BTW - I think dullbird - your vehicle did this until they changed your engine.

Well - that was the issue - my EGR valve was clogged up to the Bejezus with carbon and, given the fine electronic control of the engine's management, this was enough to cause the above mentioned effect (Austral's explanation). It's 100% eliminated now. Interestingly, I've been told to do the following - maybe once per week, drive the vehicle down the freeway in 4th at 100km/h for 3 or 4 minutes - kind of like riding a 2 stroke. This blows the cobwebs out and helps reduce carbon buildup. This was probably my problem - as I never really used to rev the engine much at all beyond 2200rpm.

In short - my Defender now drives like never before and feels as solid as a rock. I'm feeling we've turned the corner - my long (near on 3 year) period of "finishing what Solihul didn't do" appears to be over.

So I wanted to start this thread, to revisit down the track with updates to verify this really is the case - but I've now done quite a few km with zero issues - which is a first!

Secondly - I wanted to put it out there that, although some of us might have some big issues with these vehicles, it can all come good.

I'll keep you all informed.

Very nice to hear that. I hope you've got it sorted now.

Cheers

Glad to hear things are going well.

It has certainly been well earned.

Cheers

Someone remind me never to buy one of these

EGR...Don't fret too much Scallops, the Nissan series of diesels have a serious EGR = early engine problems issue, as do almost all modern diesels that try and comply with ADR's and achieve excelllent power and torque numbers.
The only way to really fix it is to block it off, which is illegal, and some engines will go into limp mode if tampered with electronically.

Good to hear the love for the Landy flowing again!

Thanks Justin,

Would you also recommend doing as Austral say and driving it, say once per week for 5 minutes, on the freeway at 100-110 km/h in 4th or 5th to "de-carbon" the engine?

I'm revving it up to 3 grand on the change up from 3rd to 4th on most changes now - once the engine is warm.

Yay!

Drive it like you stole it.

BWAHAHAHA! All that economic pootling around at 90kph. No more grandpa driving for you my friend or you'll send Grover to an early grave. He needs an occasional spankin'.

[Scallops]

Yay!

Yeah! I am having more fun with my newly adopted driving style! Thing is - you're only going to get to borrow it now - I'm not selling it - even to family!

PS - Kat reckons I've had a Stig awakening!

PPS - And Andrew - a spanking he shall get.

Gives us all hope Scallops - great to hear mate. Can I ask - with your EGR issue did you get an actual fault code the dealer could pickup? I have the same symptoms but am in MEL on a trip and local dealer can't see an egr fault code so can't get authorization for LRA to replace it. Thx Gav
