Crap diesel and associated problems
Discussion
Hi all, time for another posting from the workshop. Recently we have seen a number of X types with problem turbo vanes and actuators caused by excess soot, the result of poor grade fuel use. Check, those of you with after market mickey mouse warranties. They have been written to absolve the companies of all turbo issues caused by excess sooting or carbon build up.
X type diesel turbo faults are caused by excess sooting up of the EGR valve,causing the vehicle to run rich,which block the variable vanes on the turbo. The variable vane actuator on the turbo becomes clogged and the solenoid will fail trying to overcome the carbon build up . The solenoid is sub standard with built in obsolescence, not man enough to overcome the issues mentioned due to poor quality components. The result will be a turbo assembly change.
As far as Warranty coms are concerned , the fault would need to be diagnosed by a turbo specialist( not a Jag spec). This is what the independant engineer appointed by the warranty company will suggest to the owners.
What ever the independant engineer discovers, the warranty company will either use `wear and tear or carbon build up` as an excuse not to pay out, despite most Warranty policies covering turbos.
The two morals of this story
DO NOT to buy cheap jack warranties.
DO NOT use cheap s
te fuel
it may well be prudent to use a fuel additive to assist in reducing the carbon. Have a nice day, especially Sunday when England win 4.0

Unfortunately Jaguar cut corners just as good as the rest nowdays.
It's left to the end user to deal with. This and other internet boards are a necesssary tool, if these cars are to be kept functioning, without having to suffer inept dealer service departments.
There are enough good independants about now, and when they post good advice here, we all benefit.
Maybe a warranty could be offered by these outfits, then we could expect a fair deal.
Keep up the good work.
On the football though 4.0

S types aswell. My client posted a real, god awful reply about the warranty co on some public chatroom , don`t know which. I got a call this morning to say the warranty co have now authorised the repair within 15 mins of the posting(haha) ,now there is a suprise!.I await confirmation Monday.
Built in obsolescence is a wonderful tool. Very poor communities in third world countries making third rate components, using first rate ex British manufacturing equipment.
The horror, the horror............
Next I will discuss E5 and E10 component compatibilty in a different topic.

Other than supermarket fuel, how do you tell you got cheap-sX type diesel turbo faults are caused by excess sooting up of the EGR valve,causing the vehicle to run rich,which block the variable vanes on the turbo.

te fuel?Hi Fatboy, to some degree you have answered your own question. The cheaper the fuel, the lower number of additives.You only get what you pay for after all.
Best to stay with premium grades supplied by the bigger Petroleum companies. Less chance of the issues described.I have posted on another site the forthcoming addition of Bio Ethanol to all fuels starting 2011. All to do with Europe reducing its` CO2 emissions.I`m not sure if Bio fuels will cause more problems than we can anticipate, especially with components and fuel line copatability. Some manufacturers are way behind with testing due to the economic stuation. E5 will be first, that is 5% Bio ethanol followed by E10(10%) by 2013. The new aditive will hit hard the older car market and I can see a host of issues in the future.

Alternatively, buy a petrol 
That was my thoughts. A nice 3Lt Estate with a Manual gearbox, Oh look there is one in the drive.
Most manufacturers have moved forward with technology on fuel lines/ pumps etc with the new models and new fuel ( forget asking the showroom/ dealer numpties). Ethanol is highly agressive to rubber and generates considerable amounts of water.
Seems to me that with every successive tranche in the CO2 malarkey, the beleagured makers have to put in another 2Ks-worth of hi-tech kit that will eventually break.
And so as Europe legislates itself into a bankrupt standstill in the name of PC, the Chinese, who have no such qualms, buy the world.

Yes, but they'll all keel over from emphysema shortly afterwards; then the EU legion will rule all! Mwahahahaha! And so as Europe legislates itself into a bankrupt standstill in the name of PC, the Chinese, who have no such qualms, buy the world.

The worrying thing though is if the calibration does not change there may be some emissions effects that may be out of the region the controller works in.

I take it this problem is not fixable/avoidable with an 'Italian tuneup'?
Yes it is.And the problem isn't limited to Jaguars - basically everything with a variable vane turbo suffers from it. Either bladder the car to really get the turbo hot (M/way duty cycle) or strip the Turbo and use Innotec to clean it out - basically an industrial spec cleaner that isn't dissimilar to stuff used to clean out ovens...

Really? There a govenemnt directive to make this clear in at the pumps in 2011 so we can safely assume its not present at the moment
Read the topic regarding turbo and EGR issues.My background is in vehicle repair and restoration.What`s yours?
I design and build oil refineries. You cant safely assume Bio Ethanol isnt in your petrol, trust me its in there and has been for a good while. I will search your topic as Im interested in any problems being experienced by users. Ah I realise you refer to the soot issues, bioethanol wont be a big contributor to it but rather the heavy components present in diesel, as you say quality helps here as less heavies in quality fuel plus additives to help deal with it.Read the topic regarding turbo and EGR issues.My background is in vehicle repair and restoration.What`s yours?

Okay thanks for the research, please keep it coming. My colleagues in the trade have seen a sharp rise in turbo actuator and EGR issues in other models, due to Soot build up. If this is due to Bio Ethanol, well...........
I`ve tried the bladdering technique, it just doesn`t work.The turbo fault light re appears when Hot , that is when the variable vane actuaator seizures occur .I`m interested in the innotec cleaner method , let me know what type of Innotec cleaner.
Are we retruning to the bad old days of decoking cars I wonder.Carbon build up was due to poor grade fuels.
This procezs led to head/valve train removal to enable physical cleaning. No other additve would do an effective job, as it was always down to hard cleaning work
I can see a pattern appearing here.I have had two clients with loss of MPG on some 80/90 thou miles diesel engine cars, mainly due to the excessive carbon build up in their inlet track /valve train/, but without the turbo fault. A physical de-coke has resulted in the factory MPG figures return, certainly the carbon build up was excessive.They too were using supermarket fuel. .
