S Type Black Smoke

Recommended Posts

Driving to work the other day - everything was fine then all of a sudden, lack of power and belching out black smoke. Restricted performance on dash but remove and reinsert key and restricted performance light cleared, drive the car, not as responsive and restricted performance warning re-appears after a few seconds.

OBDII fault code reader shows No Faults Stored. MAP sensor cleaned out.

I'm at a loss - any ideas would be greatly appreciated.

Thanks guys

Hi Martyn, 

I think the cause of black smoke is unburnt fuel.  You will need to put in a diesel additive,  - something like Diesel Magic or a similar fuel system cleaning additive -- Wynne's  diesel auto max etc.  Also, use the premium fuel available --  shell v power etc.

Regards,

Peter.

Hi Martyn

My partner and I experienced similar with our 2.7D S-type just after we bought it.  At that point it had covered 52K miles on a '07 plate, and had been used mainly for "poodling about" locally.

My partner says that the amber DPF warning came on (Diesel Particulate Filter Full) a couple of times and this could be cleared by running at around 3000 rpm for a short while (15 mins or so) in lower gears.   However, twice the red warning came on and performance was restricted.

A couple of applications of Wynns additive didn't really help, as by this time the problem was beyond being solved with an additive.  A visit to a local Jaguar Independent showed that one of the EGR valves was blocking up, hence the black smoke and restricted performance. There are 2 of these on our '07 S.  The guilty one was replaced and, touch walnut veneer, there has been no problem since.

Not saying that this is the definitive answer for yourself, but the indicators are familiar.    Whatever, Mr Jaguar would say that it is not wise to continue running around when the performance  restriction keeps coming into play, as you could do some pretty nasty damage to the power unit.

Hope this helps, and we wish you well with sorting out the problem

Happy growling

Thanks guys for the info.

It looks very much like one the GET valves has given up the ghost - two new ones on order.

Strange thing: tried ordering for Jag £174 each. Ordered same part from a Land Rover supplier - two valves for £124.

Worth bearing in mind

Good morning Martyn

Good to know you are en-route to sorting the problem.  My partner says that If you are doing the job yourself, allow plenty of time as access isn't particularly easy.

Once you have done the job, you may experience an odd occasion, for a while, of the amber DPF FULL warning as the DPF will have been taking a bit of a battering.  We found that running at around 3000 rpm for 15 minutes or so in lower gears (using the manual hold) clears the issue; this negates the need (as per the Jaguar advisory) of running down the motorway at 70 mph for the same time, which isn't always convenient or practical. 

Other than that, happy growling, as always!

Hi Martyn, 

Good luck with your EGR valve change.  I have heard that one of them is quite easy, although I don't know which one.  My s  type had an engine change under warranty  when it was three years old so in effect it has only done just over 40,000 miles,

Peter.

Hi Peter

Not started the work just yet but the right hand side (drivers side) would appear to be straight forward although somewhat fiddly but the left side would appear to be somewhere where I can brush up on my French language.

Hi Martyn, 

I will think of you exercising your French!

My  case is packed and I am now waiting for the taxi to Gatwick, courtesy of SAGA, and just trying to brush up on my meagre knowledge of Italian!

It is nice and sunny in Rome and Naples!

Regards,

Peter.

Hi Martyn

It is indeed the n/s EGR that can be difficult; my partner and I decided to allow a local Jaguar Independent to do ours, when they commented that the o/s was "fiddly" but that the n/s was "b..... difficult!   They estimated usually at least a couple of hours for the n/s, so take your time and be patient.       It would probably be good policy to throw a cover over the wing tops to protect the paint because there's plenty of leaning over the wings.

We don't know what the french for "what silly s.. designed this lot", but we do bring to mind the ancient latin of "non illegitimo carborundum".   As this is a family forum, we'll not translate but we are sure you can work it out!     Meanwhile, whilst undertaking the task, do remember the happy chants of "Sacra Bleu" and "Mon Dieu", and if things get really nasty, how about a rousing chorus of "Non je regrette rien" mixed with "Allouette".   And don't forget the Cordon Bleu Fromage Frais.     Doh.

Happy growling Monsieur, excuse us while we go and take our tablets

Hi Martyn,

Could you please pop a link up to where you bought your EGR valves?

Cheers

Hi Mark

I have checked all the info received from the suppliers of my EGR valves and there is no direct contact info to be found anywhere.

The valves were purchased via ebay using the TDV6 engine as a reference point as its the same engine fitted in land/range rover as well as Jaguars but you already knew that.

The company name is "top-quality-autoparts" of which there are many companies of the same name but I found by entering the name EXACTLY as I have written it in google search, it does give you the option to go straight through to their ebay site.

Hope this helps

Well guys & gals

Both EGR valves have now been replaced and what a job they were. I think it will be a few weeks before the skin grows back on my hands - Not a job I would do again.

Did it make any difference - NONE whatsoever. So clearly that was not the fault although in fairness, I think it was only a matter of time before the old EGR valves would have caused a problem as both caked solid and one could barely move. 

So what is the problem - don't know - HELP!!!!

Lack of power - limp mode almost immediate (clears when engine switched off) - Thick black smoke (both exhaust pipes).

Any suggestions?

Hi Martyn, 

Black smoke off a diesel could be faulty injectors, or just plain dirty ones.  Some say it could be a faulty turbocharger.  Definitely something in the fuel system, though.

Regards,

Peter.

Hi

If its the diesel, I would go with faulty injectors, only way is to get them tested really

if you have a bad leaky injector, it can cause oil level to rise, is you oil level correct

you still should get a fault code

cheers

Hi Joe

No fault code is showing either stored or in real time.

One opinion is, an electronic turbo actuator is not  working correctly or at all. I have decided to book my car into a specialist garage (DTM in Bristol) and let them trace the fault.

DTM are not cheap but anything diesel, they are the guys to go to
