Going from bad to worse. Rang the dealer this afternoon for an update.
Car needs a new engine and a new turbo. Why turbo is in the singular I don't know, because it's got two of them, and it would seem odd to replace only one.
Worst thing is, they're waiting for the nod from the warranty "company" to proceed. I thought it was Jaguar who supplied the warranty, but it may of course be under-written by some-one else.
Apparently there's an issue about the car's service record, because the service that was done last year by the main dealer down south isn't showing on Jaguar's system - which would invalidate the warranty apparently data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7.
Ho-hum.
If its anything like BMW they need to contact the warranty department for authorisation to carry out the work, normally only takes a day.
Update - the car needs a new engine and both turbos - estimate £20,000 data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7.
I believe that's quite possibly more than the car's worth, so the dealer (Jaguar main dealer) is steering away from the Jaguar Approved Two-year Warranty and referring it direct to Jaguar.
I suspect they'll write it off/buy it back/exchange it for something of equal value - at least, that's what I hope they'll do.
Find it hard to see how, given that I drove it to the dealers (on other business) and it started and ran smoothly enough when the workshop manager came out to see what was what - until the metallic rattling chimed in after a couple of seconds that is, the engine and both turbos need replacing? Sounds like a broken valve stem = bits blown down into one or both turbos maybe?
Pissed off, big style data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7
Does the car use the same TDV6 thats used in the disco and well known for spinning a bearing and fudgeing the crank?
I believe it is, possibly a different state of tune, mine's 275BHP - or it was data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7. Only a software difference AFAIK. Whatever, that's something I didn't know. The lady at the dealers cheerfully mentioned that the youngest Jaguar TDV6 they'd had to replace the engine on was 4 months old, and less than 12 months isn't that uncommon data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7 . Under 40,000 miles on mine, btw, and, my annual mileage may be low these days, but I do a 250 mile round trip every 4 weeks.data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7
More likely turbo failure sending bits into the engine, it wouldn't happen the other way around.
That's what I was thinking,s##t flows downstream not upstream.
Interesting, see where you're coming from, @djbsom too. I'm trying to work out though how any fragments, from either side of the turbo, could get into the combustion chambers.
It's my understanding that the exhaust gases - and anything else data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7 that goes down the exhaust manifold(s) - spins up the turbine side of the turbocharger, which is connected by a shaft to the compressor/impeller. (same shaft, but in a separate chamber).
The compressor in turn pumps and compresses air, through the intercooler, fuel is added, and the mixture is injected at high pressure into the individual cylinders.
So any stray bits from the inlet (compressor) side would have to pumped through the injectors to get inside the engine wouldn't they? It's hard to see that happening data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7.
Conversely, if the turbine (exhaust) side fails, it's hard to imagine any bits travelling against the flow of the exhaust gases and getting into a cylinder(s) past an exhaust valve?
Yeah, grandmother/eggs, sorry guys, I know, but just trying to rationalise the need for a new engine and two new turbos - just seems so catastrophic.
I probably think too much - it's only a bleedin' car data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7
EDIT Scrub all that - they've just phoned and said they've found metal particles in the oil filter, looking very much like main bearing metal - see @Hpi_matrix 's post #14, so they're awaiting instructions from Jaguar UK. If it is the mains they can't repair - crank can't be re-ground, so it has to be a new engine data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7
That wouldn't be my understanding.
The air, whether forced induction (turbo/super-charged) or not, enters the cylinders through the inlet valves, and only the fuel is injected, so the fuel only mixes with the air once in the cylinders.
Quite right, I over-simplified it - wrongly data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7
