THP power loss

[alex102]

And did that fix the fault? I know for a fact that a dealership in Romania said that the reason for the fault is that the driver did not rev the car enough, but that's a stupid answer. All they do is reset the ECU and hope that it won't happen again. So i think i'll have to go with the solution to this problem.

Yes, sounds like you've got the timing chain tensioner problem. Welcome to the club!

[alex102]

Thank you for the advice. I'll try and ask for a "timing chain" replacement. I have read a lot about this problem that seems to affect all the cars equipped with this engine. Fingers crossed.

Can i still drive my car of it is in limp mode?

Can i still drive my car of it is in limp mode?

I was told yes, but I can't help wondering whether driving it in that state caused the premature wear on the VVT unit that led to a further big repair. I'd press for the cam chain & tensioner replacement ASAP, & go very easy in the meantime.

i told CUK that it was in limp mode and i felt it was a safety risk when pulling out of junctions / roundabouts and he agreed got me into local dealership next day and hired me a car :| tell um its not safe to drive and they cant tell you it is

Popped up the hood today, but i couldn't spot the spark plugs. Is oil around the spark plugs also a sign of timing problems?

I bought the car a few days ago. After taking a look in the log book i noticed that "oil and filter" was changed under warranty. That's a strange thing to replace under warranty... any idea why?

to try and fix the power loss.

[alex102]

Great! So there's metal in the oil and timing change could fix that...

[Rickzayne]

dont think they know a fix yet

On early THPs the wrong oil was used, and there was an info rapid instruction to dealers to change the oil. Do a search on here & you should find it.

[alex102]

Okay, thanks. I've read about it all day, but no one seems to know exactly what's happening. I also checked out the M*N* forums in the US, and those people have really big problems. A few engines blew up.

I'll read more about it in the morning, i'm glad to hear that i'll find all the information i need here.

UPDATE: After driving at a constant rpm (2.500 rpm/minute) for a few minutes, the car refused to accelerate any more. I turned it off, then turned it back on and the warning light is gone. But the car still isn't accelerating as it should.

yh id be careful revving it and trusting it after its done it too you , you never no wots goin on in there now , search for the info rapid link posted by dangerousfish theres stuff on there thts about hesitation etc. keep eyes on spark plugs , oil level and colour and your water level. other thn tht happy days

[alex102]

Thanks matt, found the thread but there's no good news. The fix is oil change, which has already been performed in October or November, under warranty. I don't think this problem will go away soon.

yh bin through it hopin my "fix" is gonna work had the whole power loss engine management light and it took them 5 visits to dealership, 14 days with the car and a 150 mile test drive by dealership to change some hoses :|.

[alex102]

So you're telling me that the power loss has an infinite number of possible causes... ) Good news for me, as in Romania dealerships don't have a lot of experience with the THP engine! Do you have any idea if the problem has been fixed for the new ones?
