What to do when the dealer can't find the issue with your car which is under warranty

[alittlebitconcerned]

Hi all. I'm after some advice re an issue with my car that the service centre cannot find and my Puma is still under warranty so I obviously don't want to pony up myself.
Three different times I have been at about 3000mtrs altitude in misty/cloudy conditions when I get a loud squeeling screeching sound kind of like a belt slipping. One independant LR specialist has suggested it could be the vanes in the turbo sticking because he had the same issue with his and in the same conditions.
I don't think that LR would like to come on a long drive into the clouds with me and they certainly can't reproduce the same conditions in town so I'm hoping for a bit of advice on how to get it sorted out under warranty.
Any suggetions are appreciated.

Umm - I think you are overestimating your altitude by just a tad if you are in Australia (your location says Sydney).

Maybe that is why they don't believe you...??? :p

More details on the (realistic) altitude the noise starts and stops at would help.

it must be a flying puma Ben:p

Don't know Jack **** about Puma's, but if it's a Td5, check to see if it's broken a manifold stud

Matt I would film (most mobile phones have the ability to film).....I filmed a lot of things on mine, cant get any better proof then them seeing and hearing for themselves especially if they are unsuccessful at recreating.

Turbos on Defenders aren't generally a problem.

Thanks guys; good idea re camera. I'll give it a go. Hopefully they will accept it.
Considering Kosciusko is just over 2200mtrs I guess I got my height a little out. I blame my gps and my complete lack of knowing stuff :)

I'll check it out. Thanks Wardy.

maybe the GPS is reading in feet, not metres? you can change it.

[alittlebitconcerned]

Ahhhh... that could be it, I will check. Mind you this is the same gps that a third the way across the harbour bridge suggested I make a left hand turn. To be fair it is programmed for off road use. ;)

Also from memory the highest drivable road in Aust is 1780mtrs and that's the track up to Mt Pinnibar, unless you work for NPWS and then Rawson Pass is, the track up to Mt Kosciuszko:D

Well if you did make a lefty off the bridge a 1/3 of the way across you would certainly be Off-Road, (for a while anyway), Regards Frank.

I have driven my Tdi to some of the highest parts of Oz and my turbo squeeched all the way,it's the thin air that causes them to do it. Pat

[alittlebitconcerned]

Yes I would Frank! I have a snorkel that would finally be put to use too.

Considering that the height(s) my suspected turbo issue occured at was more along the lines of 1000mtrs (thanks blackbuttdisco, gps was set to feet not mtrs as you suggested :confused:), I wonder then if this height would have any effect at all? If not, the only constant would then be that each time it happened I was in heavy cloud/fog conditions and had been driving for awhile.
I'll arm myself with a recorder and wait...

Thanks Pat, now I'm getting somewhere. Do you know why it does this (apart from the thin air that is) and do you know if it is a fault with the turbo and therefore something to be concerned about? Did you travel with other turbo'ed vehicles and did it happen to them?
Cheers.

Exactly what roads are you driving on when it happens? Might give some of an idea as to how high exactly you were at the time. Then get someone else with a puma to drive the road with you and compare the difference. Assuming the other puma doesnt make the noise, film that, then film yours and take it to the dealer. Pretty decent proof that yours has an issue.
