Puma slight power loss - any ideas?

[The Cone of Silence]

Morning all

Could really use your help today with Monty ('08 110 Wagon) as time is not on my side.

I drove from North Sydney to Mortdale this morning as Daniel at Mulgo is installing my roof rack, awning and rooftop tent for me before I go away on a trip up to Tamworth and surrounds tomorrow...terribly excited...a mate's birthday at Willow Tree....but I digress.

The problem
On the way down to Mortdale, while travelling at 80kph through the tunnel on the M5, I noticed a sudden drop in power - down to about 75% of what I'd usually expect. Throttle response was sluggish - acceleration wasn't 'all there'.

Conditions
Road was flat to very slight incline.
Temperature gauge read below halfway and the radiator and intercooler are pretty mud free after some sustained hosing. Ambient temperature was below 20C I'd say.
No engine warning light


I got to Mortdale ok - with sustained engine performance below what I'm used to, i.e. for another ten minutes and with stops and starts at lights etc, it still seemed to have about 75% of the usual acceleration. My first thought was that perhaps the turbo wasn't working but the turbo noise was certainly there.

Further problem
At one point the hazard warning lights came on all by themselves and after about a second, switched themselves off.
This could be the result of some ham-fisted gorilla installing my new stereo last weekend (a normal sized unit) and messing about with the wires behind it but that remains to be seen.

These don't sound like related issues to me but Pumas never fail to surprise me...so I shan't rule it out.

Thoughts?

Water/ dirt in fuel?
EGR?
Hoses?

Does it sound like something I can fix this evening when I pick up the vehicle or is it sounding like a spare part is required. Would hate to miss out on my trip after Hannibal Safari and Mulgo have gone to such an effort to ensure the gear is ready on time for its maiden voyage (top effort boys, well done and thank you!)

A very nervous Bobby (Monty is out of warranty).

Hi, it's worth checking the fuel line between the filter and tank. I have read of blockages here causing the symptoms you describe, (mainly in the UK however).

Best of luck,

Tim

There seems to be a run of loose Turbo hoses recently. That's where I would start.

[Marty110]

yeah, check the bottom intercooler hose - they rub on the steering and can fail - this happened to me and now have replaced with Terrafirma silicone hoses as they are better and much cheaper than the crappy LR rubber ones - then zip tie the lower hose up off the steering. Hope this is all it is

[Marty110]

P.S. If Daniel has a Nanocom, plug it in and the error sode for turbo underboost will read if it is the intercooler hose - but then crawling under the car and having a look will tell you too!!....

[The Cone of Silence]

Thanks guys. I'll have a butchers at it this evening and hopefully it's just a worn hose that I can get replaced tomorrow first thing. Inquiries have already been made regarding a new performance intercooler and silicone hose kit.

I'm assuming that if it's a worn hose, I'd be belching black smoke out of the exhaust from over-fuelling?

I'll keep an eye out for it. Either way, a bit of a nurse home is in order first of all.

It depends on where in the system it is... e.g. If the hose has come off before an air-flow sensor, you won't notice anything as the sensor will be detecting a drop in air-flow and therefore reducing the fuel.

Check the hoses, air filter, etc... but if the car is still running smoothly, not belching smoke, etc... I'd suspect something like the throttle potentiometer.

Have you checked the Dilithium Crystals and the Flux Capacitor?:eek:

Nah just kidding sorry I cant help, I really hope it amounts to something very simple and inexpensive, good luck. Let us know how you go.

[justinc]

In all likelihood, you may have inadvertently snagged your toe hitch on another vehicle at the traffic lights prior to entering the tunnel,, and towed them all the way to Mortdale. Did you check for an attached B double or other similar sized object? :D:D:D:D

Seriously now, the intercooler hoses are my first thought, especially the one near the steering column

Babs, don't get to cheeky:p, you pick yours up today so your adventure is just starting. Lets hope the new Ddci is minimal on the wrong kind of adventure.:eek:

[The Cone of Silence]

Had a look at it last night - the steering has definitely been rubbing on the hose but not to the extent that it's done any real damage. Not a great design but I suspect the hose is only required to last long enough to get it through the warranty period, right? Such a cynic...

The hose did feel very soft to the touch though, which makes me thing it may have delaminated on the inside. I'm not sure how firm it's supposed to be. I couldn't see any clips loose or detached, so I shall give the car to the boys at Ayres this morning and if the Gods are kind, I'll be able to get on the road at lunchtime and head away to Willow Tree for the weekend.

Like you Babs, I'm hoping for something easy and inexpensive to fix!

Will update once I've found out the culprit. Thanks for your thoughts guys, as always.

Don't forget Bobby, as much as these trucks can be a pain, they usually don't need a tilt tray home.
Is it full of weight? just something from left field.
I can drive mine to work empty and it goes well, but fill it with work gear and come home and its down a bit on response.

[Babs]

Bobby,

I pray you will be on your way.

Awesome up at Willow Tree, I used to get around there quite a bit made a few friends over the years all from that region. Which reminds me have a mate in Murrindi that I have not spoken to in years.

I kick around east of there these days out past Gundy hard not to stop in at the Linga Longa, great Steak.

Anyways I'm sure you will be on your way and have a safe trip. ;)

I do have a stack of stuff in the back but it's always in there....and the performance reduction happened part way through the journey. I got the hot sweats too when it happened - does anyone else get that?

When something happens and you know it's serious but you don't know what it is and all you think about is having to stop, hit the hazards and be "that guy" blocking a lane of the M5 in a tunnel because there's no hard shoulder?!

Maybe it's just me.
Maybe it's worth a separate thread! How we react when something goes clunk, or boom!, or psssssshhhft, or bang bang bang or the dials light up like a christmas tree and the hazards turn themselves on inexplicably.

I started to suffer from these symptoms not long after hitting 100k when I realised I would be paying to fix the issues.

Prior to that is was only when the wife nearly took out cars on the motorway.

Hope you find a quick, easy and inexpensive fix!!

[newhue]

when I start to think about the end of my I get twitchy and easily rattled. At the moment I don't really care what happens...... um well I do, but at least I'm not paying for it.

I have beginners luck I think, or lack of it. But I have been that guy twice.
Early in the piece the new truck decided it was going no further after I filled it up at a servo. Blocked the lane for a bit until I could muster some help to push it out of the lane. I watched the people watching me while I waited for the tilt tray.

And my first outing in the Series 1, it just so happened to stop at a major intersection. I thought no worries I'll pop the hazards on, nah no hazards. My induction to series ownership was pushing it out of the way across the intersection with lots of traffic looking on and probably wondering..........why

if it doesn't kill you it makes you stronger or something so they say

[The Cone of Silence]

So, as it turned out, the hoses are all fine and the fuel line is fine....the issue was with the air filter. Again!

I had written it off as a potential cause as I've been very careful in water crossings but I guess driving behind my mates has kicked up enough dust and at some point there's been enough rain in there to send it all into the air box. Should have checked. Feel foolish... :blush:

I think it's high time I got a filter at the top of the snorkel. Is a footy sock good enough? Can I get a filter for the Safari Snorkel that won't excessively restrict airflow?

Good idea. My (first) LR arrives tomorrow... I come to LR ownership fresh out of 15yrs of air-cooled VW ownership and know these feelings well... those heartstopping moments when the engine suddenly gives a chuff chuff and then dies... in the middle lane of the freeway :eek:

Each knock, jolt, creak, rattle accompanied by a shriek from the wife "what was that, and how much is it going to cost?"...

Did anyone ever try one of these?

I have similarly had a clogged paper filter lead to loss of power.
