New turbo

Regardless of the mileage on the car, if you only bought it in June, then quite soon got a remap done, what actual evidence do you have of the car's history prior to that?
Just because an oil change has been done, for example, it could have been filled with treacle for all you know.
With the fairly thin file of facts that you've given us it is hard to make judgements, but with a car that you've only owned a short while and therefore are not 100% sure of the history of, it is a big jump to assume the remap alone caused the issue.
One thing that stands out to me on this forum during the recent spate of N20 remapping is that nigh on every owner has had their car quite a while, got to know it and can vouch for it being well maintained.
I am NOT saying you are wrong, but with such a recent purchase there are so many unknowns that could have caused the problem.

Regardless of all that, by speaking to people on this forum you have already discovered that you've been over-quoted by a factor of three!
In your shoes I think I may be asking forum members in your locality to recommend a decent Indy to fit you a new turbo without completely emptying your bank.

Good luck, hope it all gets sorted without too much hassle.
 
Another thought just crossed my mind (a perilous journey :roll: ).
I can never quite get my head round this condition based servicing malarkey, but if the car has only done 10k since new, even though it is a 2015 model, is there a chance the original oil is still in there?
I could be wrong I know.

Should have had two oil changes by now if the 2 yearly timing schedules have been adhered to despite the mileage. I can’t imagine you’d buy a car with no service history at this age right...?

Wether it’s actually been physically changed is another thing altogether if it’s been to the main dealers.... :roll:

I’m sure someone else has blown a N20 turbo but through my various research I never stumbled on anyone who had publicised it...

Given that a lot of the re-maps are copies of each other it would seem strange that one was ‘rogue’...

But as I found out the hard way for unexplained reasons my ‘quality supplier re-map’ performed by a ‘quality garage’ was duff...

So maybe it was finger trouble with the installer and he pressed a ‘wrong button’ somewhere..

The N20 has the run on coolant flow to help obviate oil cooking/ coking by shutting off a hot turbo without an idle time..not sure if someone could have inadvertently deleted that function when re-mapped..

10,000 miles seems premature for oil flow inspired bearing failure...many N20s have gone past 100k miles with no recorded turbo issues..

Those that comment strongly suggest 5k mile oil changes and using premium grade oils like the Redline product range rather than the mass marketed oils...

So do you think it was the remap that caused it mate ?
10 days after I had it done and I only drove it 3 times in that time :headbang:

You and us will never now know..

Had you taken the car to a 'specialist' in re-mapping, preferably with a rolling road and with the normal BMKW car diagnostics the answer would have been probably very obvious.. but that's an 'if' that like many you didn't explore..

So.. get a re-conditioned turbo either from a supplier like Autodoc or find a turbo re-build guy and suck it up..

The recommendations here from collective experience is have a re-map done with a rolling road to cross check your result..

All IMHO..

No its had the right services up to date

You just assume that because of the mileage , the fact i bought it from a 72 year old man who garaged it , and it looks like new and had all the servicing done , and had assurances from the mapping company there would be no problems due to all thses factors , things would be fine 😔

I did take it to a Specialist who said the turbo was damaged but couldn't say why unless he opened it up , which would have cost even more money 😒
And even then you can't prove whats the cause only speculate
 
Have you personally carried out any other work to the car, like fitting an induction kit for instance?

I'm curious to understand what a Dyno would show up? I guess that if the 'before' power was significantly below expectation it might suggest further investigation. Is there more it would reveal?

It could also show up over boost with power levels higher than expected at lower rpm.

If you had read what I wrote carefully you would see that there was no accusation in there at all. In fact I rewrote it several times to try to ensure it didn't read that way. I was working on the limited information you had given, to maybe come up with some other plausible reason for the failure.

As it happens, now you mention the 72 year old man bit let me add in a touch of realism.
Years back I drove a friend from Norfolk to Wales to collect a Tickford Capri he had just bought. It had been lovingly cared for by an old gent, with full service history, oil changes every 3k etc etc. Lived in a garage with insulated walls and carpet! Oh, and it 'looks like new'. What could possibly be wrong with that?
Within a month of getting it home the turbo failed!. The car had done 23k at this point.
Talking to the previous owner he then mentioned that as he couldn't really use it much any more, he went out to the garage every Saturday morning, started it up, ran it for about 2 minutes, including a good rev up to 'clear it out'. Then turned it straight off and went indoors.
So even a perfect service history cannot show the way the car has been treated.
Hence my suggestion that owning it for a little longer and making sure you knew it well, may (just may) have highlighted issues before you boosted it more.

Was only trying to point out to you that you could, just possibly, be about to slag off a tuning company with no evidence other than what 'a turbo specialist said'.
Be careful before you go to print with that.

I knew a guy thats dad had a Carlton and drove it like a granny everywhere he went, never revving it. The top end of the engine was knacked and coked up with very low miles on it.

To amplify what SmartBear said...

When hooked up on the dyno and plugged into the data recorders all manner of things would show up...

Most importantly it would show what the operator was asking the car to do versus what the car is actually doing and what the sensors say...of which there are many..

A skilled operator could deduce what the re-map is doing, how it’s doing it and how the car is responding to it...

Again, based on past experience the operator could reasonably deduce whether the map is ‘pushing things’ and/or that other systems were not working well and/or limiting the outcomes..

Thanks - makes sense. I guess the real key here is more the "skilled operator" than the dyno run alone!

You seem to have taken my post as having a pop at you mate but I didn’t mean it like that at all lol 😆
 
Be sure you get to the bottom of why the original turbo failed first before throwing a new one at the car. Components such as a turbo do not often just fail, they are normally the victim of another failure elsewhere.

If not investigated properly you could find yourself back with another failed turbo after 10 days.

I have worked closely with the motor trade previously, and one area I spent a lot of time working on was failed turbos, especially that of the 1.6 dv6Peugeot engine, found in just about everything nowadays. The turbo was never the issue, it was always down to oil supply or lack of it typically.

The problem with a low mileage car is items that are design to be well lubricated or rotated don’t get the use they need. Seals can perish or go brittle, oil quality can deteriorate rapidly if not getting up to full operating temps etc.

There is lots more going in here than just a failed turbo. The fact that you have w noticeable whine says to me it’s an oil problem and the bearings have failed. Either way the turbo will need a rebuild or replacement, but you need to find what caused this failure first otherwise it’s going to be an even more expensive road to recovery.
