This afternoon it seems my turbo has gone on my 06 Toyota Avensis d4d 2.2 80K on the clock.

Its not picking up any speed and on uphills its coming to a near-stand still. Standing still the rev meter doesnt go above 3000 revs.

Just before i had the issues i heard a whistling sound too - not loud but loud enough to know it wasnt a general sound

Took it to the garage where they've checked the valves there was some residue which was cleaned. Unfortunately its still having issues.

They've said its the turbo thats packed up. However another user on another forum has said it maybe turbo pipe thats cracked. would that be easy to spot or not?

Finally on the subject of new vs used, the price difference is about £600+ - is there a risk with the used apart from the fact that it may break down etc or would it just be worthwhile to get it newly fitted?

There are loads of things it could be before "the turbo has packed up".

There are numberous sensors and the like - for example I changed the OHs air filter a couple of months ago and forgot to reconnect the sensor on airbox inlet pipe - got the exact symptoms you describe. Start off with the cheap, obvious stuff.

Take it somewhere competent before you write of the turbo.

Working on a 406 HDI I cracked the Turbo inlet pipe once (didn't find out till after), the car then had the same symptoms as you describe. If there is a leak it will be easy enough to notice if you have a look under the bonnet with the engine running, you should start there...

As said it could be many things, if a turbo goes you can usually tell from a ending noise a bit like a belt whine, or lots of smoke through the motor or oil out of it.

A blown boost pipe, knackered MAF, map sensor gone, even things like crank sensors and egr valves can give problems, as well as injectors that wil make it go into limp mode and limit performance.
So get it checked out and with luck it won't be too costly.

Oh and don't EVER call it a rev meter on here again.............

The mechanic did mention oil on the turbo - would this be symptomatic of a cracked pipe?

I'll have to take a look tomorrow at this.

There was heavy smoke for about 20/30 seconds of revving the engine, but since then its as it should be.

Boost leak mate, turbo should be fine. If the turbo wasn't fine you'd have a bad spooling noise (destroyed compressor wheel) and probably a bit of smoke- (you can check by removing the air filter pipe and physically looking at it and making sure there is only a tiny bit of play).

I've taken off the air filter pipe and had a look at the turbo i cant see any crack on it.

at the garage as the mechanics were revving the engine for about 30 seconds there was alot of smoke but this was before they cleared out the valve at the front.

Blocked fuel filter.

Dog biscuits in the air filter

Pipe off the waste gate actuator.

An injector problem causing too much leak off.

This was my first thought.

hehe

I was once called to a dealership who had a similar running issue with a car.

it transpired that the owner had a dog and kept a large sack of dog biscuits in the garage.

Mr Mouse had been merrily running back and forward between the dog biscuits and the air box, making a cosy little nest.

He handed the owner half a carrier bag of biscuits when he came to collect his car. hehe

This sounds like an EGR valve or turbo actuation problem, or a split turbo pipe as suggested up there ^
It could be the turbo itself but the smog coming out of the exhaust would be burning engine oil and not the usual diesel soot.

unfortunately i dont have a dog nor are the mice around here clever enough to go from my kitchen to my car frown

i think i'm going to have to give it a dealer come monday.

its beginning to look like an expensive proposition already. let them plug in their computer and get the problem

it could be any range of them and i dont think any good will come of guess work!!

EGR valve blocking up the inlet plenum / mani I reckon. A big bit of crud broke off, wnet through the moter, hence the smoke and dull performace.

evil things on diesels, block them up!!

The Egr valve was opened at the garage and it had alot of residue. this was cleaned up and air sprayed clean.

the symptoms still persisted after this.

would the residue cause enough of an issue to cause the problems?

Hi folks i'll give a lil update

took it to the vantage toyota garage where they checked it out and i'm honestly lost for words

it turns out you guys were right. the garage i took to was wrong.

the turbo itself is fine.

the seal from the the air filter to the turbo had worn away and worked its way loose. as a result the turbo wasnt doing its job.

they've fitted it back on as a temporary measure and i'm going back tomorrow to have this seal refitted.

at most at a cost of £100.

I'm just surprised they didnt pick it up at this garage i went to that it was meant to be tightly fitted and sealed.

thank you everyone on here for the advice you gave!
