is my turbo dead?

darich

Update...spoke to my non-mechanic but VERY knowledgeable mate and he suggested a sensor had failed. He listed several that could fail and gave me a couple of examples from his own experience and of a few mutual mates who had replaced sensors having experienced the same as me.

He suggested disconnecting the battery on the off chance that the sensor failure was intermittent/temporary and the loss of power to the ecu would clear the memory and let the car run properly again.
I disconnected the battery for 5mins and drove round the block - the car is perfect!!!

I still need to get it checked though but at least i know it's not the turbo, fuel pump or air flow meter all of which can be quite costly. He told me that the sensors he and mutual friends have replaced have varied between £35 and £65. So diagnostic test, sensor and fitting should hopefully be a fraction of a new turbo or fuel pump!!!

Thanks to all for the tips and help!!

I was driving my gf's car home tonight...a 2004 Nissan Almera 2.2 tdi. Nothing exciting but a decent enough car.
As i was approaching the top of the slip road i felt a massive drop in power - as if i had hit the rev limiter. I was surprised since i was certain i wasn't that high up the revs....anyway....the road then bends a bit so i was off the power but when i went back on thre was hardly anything there.
I also noticed there was no whistle anymore - just regular diesel sounds.
There was no noise, no sudden cloud of smoke from the back...just a sudden loss of power.

It meant that the car would barely go above 35mph and 2000rpm...not ideal on the motorway. Rightly or wrongly i figured i was safer to keep moving on the hard shoulder at around 35-40 with the hazards on than stop and wait for the AA. Ileft the motorway at the next slip and continued home on non-motorway roads- total distance driven after power loss - approx 10miles barely above 2000rpm.

Obviously home now and the car made it too. It idles ok. Doesn't sound any different, other than the lack of turbo whistle. No smoke at all from the car.

Is the turbo shot? is it more likely to be a burst/split hose?
any ideas from anyone??

thanks

Now look, it's a modern japanese car, made before renault got involved, there can't possibly be anything wrong with it:rolleyes::rolleyes::rolleyes::rolleyes::rolleyes:, can there,


Fuse lit.

Sorry to burst your bubble Bri, but Renault got their mucky fingers in to Nissan as long back as the year 2000.

It has gone downhill since..

You know I really wasn't sure about that one but I thought I'd chance it anyway?

Anyway, you haven't told me who makes a "proper" Japanese car yet anyway

Daihatsu make cars in Japan, the Sirion is definately made there, of course there must be others, but it is all getting very blurred these days.;)

Will do.
Nothing confirmed and won't be until it's plugged into a diagnostic machine.....hopefully early next week. I'll post a message with the actual problem.....just hope it is an inexpensive sensor!!!

Usually a sensor fault will cause the check engine or engine management light to come on.

Another possible cause of power loss in diesels is a blocked exhaust filter. Obviously not in this case ( I doubt your car has one) but may be some use if anyone in future has the same issues.

Just for my own curiosity does anyone else think that it sounds like the car put itself in limp mode?
