Just got myself a 3door 308GT. Very nice, like the car. :cool:

I thought it was quite nippy when I had put my foot down as the revs picked up, "That'll be the turbo then." I thought to myself. :thumb:

That was until about the same time the weather got very cold (10 days ago?). Coincidence? I thought turbos were supposed to run better with colder/denser air. :confused:

So anyway, the car drives fine, no fault codes. Fine that is if it were a 1.6 without a turbo. Basically there is no more boost. Eh, I'm not exactly David Hasselhoff. so who needs turbo boost when the roads are this iced up? Well heck, I like to know its there even if I can't use it! :rolleyes:

Is this a cold weather issue or something that needs investigating by Peugeot?

They're not a ball of lightning (though no slouch either), and the map on the 308 is much better than the lumpy delivery on the 207, so it should feel smooth and linear with no pronounced kick.

Still, if you're not sure get it checked out. Maybe the supplying dealer will let you try a regular 1.6 as a comparison?

Nice motor BTW.

Thanks for the reply. Actually, I have just driven a regular P308 1.6 I think powerwise it felt almost exactly like mine does now.

I'd have to say my car 'felt' slightly better than linear until recently, now it feels slightly less than linear, perhaps almost a third drop. There used to be enough power to experience a little torque steer under hard acceleration, all that edgy feeling has all gone now.

Its still under warranty so I think I'll have to book her in. While they're checking the 'turbo boost' I will ask them to install the talking computer from the top spec RCZ that addresses me as 'Michael' in a camp voice. :D

I've booked her in tomorrow at my local dealership, they'll run a diagnostic and take her for a test drive. Charge is £75 (apparently only if they find a problem), wear and tear repairs I pay for, but anything else should be covered under warranty. They were unable to specify the cost of making a K.I.T. upgrade. :shrug:

I'll let you know the outcome.

Peugeot ran diagnostics: No problems found.

Peugeot mechanic test drive: No problems found.

Peugeot suggestion: Book it in for a whole day for extensive testing.

So I decided to think about it. I Drove it away and found it drove like a champ again. In fact I gave myself a shock because I expected much less power, so I put my foot down, torque steer was back and everything, so was the much fruitier exhaust note!

Yeh, so something they did with the diagnostic software seems to have fixed the turbo (or whatever). This wasn't an intermittent problem, it had been every time I drove, engine hot or cold. Anyway, I advised them by phone and they were just like, "oh, if it happens again let us know". There was no charge for today.

Did they press the secret turbo button? Had I turned it off by accident? :confused:

I'm really no wiser what the hell the last two weeks have been about, but at least my baby is back. :D

Had a few weeks of really good driving then the power went slack again. Instead of 0-60 in 8.5 seconds, it can almost do 50-60 in 8.5 seconds.

This problem is somewhat intermittent, a few times the power comes back (always for a whole journey). Anybody got any ideas please?

When were the air and fuel filters last changed? Fuel system should also be checked for vacuum/air leaks, but this is probably a job for a specialist.

Thanks for your reply. :)

First service was about two or three months ago (20k miles). But looking at what is in the service looks like neither filter has been changed. I can try changing these to see if it helps.

Ah, sad to say that as time goes on this sounds like a fault that afflicts a lot of the turbo'd Prince engines - that's what happens when you let BMW redesign a perfectly good Peugeot TU unit for you!

There are 2 main problems that afflict this unit...

1) Software issues that suddenly leave you with big holes in the power delivery, usually half-way through a really tight overtake. However, yours is one of the later cars with this engine so I would hope that it would've been addressed by the time yours was made.

2) More worrying. Somewhere in the valvetrain is a metal peg or key that keeps the cams properly timed up. This can wear/fail, and while it only makes a fractional difference to the mechanical timing of the engine, it is sufficient to cause the ECU to get confused and throw a wobbly as the signals it received from the camshaft angle sensors are then at odds with what the rest of the engine is telling it.

At this stage, from what you tell us, I'd be plumping for number 2 at the moment.

BTW, if it's under the manufacturers warranty, and not an extended aftermarket warranty, all inspections related to reported faults (aside from wear and tear, or otherwise damaged through misuse, collision etc) are free, regardless of whether they find a fault or not. The EU says this must be the case - after all, it's hardly your fault if it's an intermittent problem and the car is behaving the day it goes on, or their techies are dullards and can't find it.

Thanks Chopper.

Ironically they recalled the car for a software "upgrade" shortly before the first problem started, hmm. I think I'll have to go back to Peugeot while I still have some warranty left on the car.

:shrug: Update:
Had the car into Peugeot, again, but it wasn't playing up at the time. Naturally after half a day they found nothing. Booked it in for a whole week for testing.

Last night; complete loss of power, red "oil can icon" light flashed, then red "STOP" light. Car made nasty noise on restart attempt. Called out the AA, he checked dipstick (which seemed ok) but when looking inside oil filler cap we could see lumps of sheered off metal :yikes: (presume it was bits of rocker or something as it was too dark to see). AA guy didn't know what it was or the cause, he guessed perhaps something to do with the
cam/cam belt and/or the rockers or the variable valve timing....
...no sh*t Sherlock!?! :confused:

Towed into Peugeot who are currently "having a look".... thank my lucky stars its still under warranty.

Peugeot dealer said all the rockers have broken, but the timing chain hasn't, which they would normally have expected. Therefore until the engine is pulled they can't say what the cause is, but they suspect a faulty oil pump.

The car will probably need a new engine, certainly a new head. Either way it has to be pulled out. Waiting for Peugeot assessors to confirm the warranty before they start any 'big' work.

The sad thing is they can't (and probably now won't ever be able to) say either way if the power loss was in some way connected to this breakage of the rockers. So while I may get a new engine the ongoing intermittant power loss could still be present.... :nono:

*sigh*

Also since the one service was done at ~21,480miles, not at 20,000 with 1000miles wiggle room they say I might not be covered by warranty.

A new engine would be ~£5,000

I'm beginning to dislike Pugs. :cursing:

i hope your all covered under warrenty, but they will try and wiggle out of this one, so they wont loose money. but because you have been back twice (if i have read correctly) to complain about a fault which, could be engine related and you let them look, so they should, i repeat should, of seen this coming, if they did there job right in the first place. you could possibly use this as an excuse/reason for them to do it under warrenty.

as for the 1000 miles, that is nothing, you can claim to have been at work and unable to get the car into a service within that time...if you know what i mean...

hope you get this sorted mate :thumb:

Cheers cck2k9! I appreciate all the support I can get right now!

I should find out tomorrow. I reckon Peugeot might authorise the engine to be pulled to find the cause and then decide, but I guess I'll have to wait and see.

Dislike pugs? The TU engine was a perfectly tough old boot until BMW came along and redeveloped the block to create the Prince engines.

Hopefully you'll get a whole new mill, but as nice as they are even when they're running well the THP is probably the one and only lousy motor in the current range.

Still, BMW/PSA were the first to foresee the need for smaller bore high output motors, and despite the mocking they were right - WRC is now down to 1.6 turbo units from this year, making the 2 litre turbo a completely pointless and redundant unit in any range, with no need any more to homologate a 2 litre tubbie for motorsport, and no marketing kudos back to the same capacity in road cars, and with the next range of Euro emissions regs due to come into force the 2 litre petrol tubbie will become extinct. Then everyone'll be clamouring for a small-bore-tubby-four and then everyone will be suffering explodo-engino as they get to grips with reliably extracting big power from small cubes...except they'll in the main be a generation behind BMW/PSA in doing so.

Nah, I love Pugs really. My other half has always had Pugs as well, she loves hers too. I'm just frustrated with the situation, or rather the possible situation....

Peugeot today authorised the removal of the head to discover the cause of the rocker breakage. I doubt they would have bothered if they were going to tell me to "jog on". I guess I'll find out where this is going later this week.

Interesting what you said though, and yeh I bet you'll be proved right about the death knell of the 2litre turbo. You've made me think I've been a BMW/PSA guinea pig with my "explodo-engino"!

All things being equal; like never having any power loss problems &/or broken rockers and Peugeot being cool about my warranty, I have to say that my 308 drove beautifully when it did work. :lol:

RESULT!

Local dealer just called, Peugeot have authorized a new engine. And I can keep the courtsey car until they've got it in next week! :thumb:

Apparently the timing belt torsioner had failed, which caused the rocker arm to break off and go into the oil pump... they suspect. They're not 100% certain cause there isn't much left, but thats what they believe. The torsioner slipping previously may have caused power loss in the past as well...but they admit they're (educated)guessing at that.

Reason for timing belt tensioner failing: "unknown".

Actually...NOT. :(

Turns out now my Pug is a Maltese import and they only have 2 year warranty, not 3year..my car being 2 1/2 years old. Due to the oversight, my local dealer is offering to replace the engine at cost to Peaugeot. Which works out at £4100+VAT.

They're 'aving a Turkish...
