Restricted performance, orange light, whistling from motor

Checked the error codes, P1074 and P1000

 

Started about three weeks ago when I picked the care up after several weeks in the garage. Required jump start, then, about 1km out, went into limp home mode with gearbox fault message showing. Replaced battery, but on the way back to the garage the engine light and the battery light came on. Checked battery voltage - 11.99v with motor off, 12.40v motor idling.

 

Picked the car up yesterday, started fine but engine light still on, though battery light turned itself off. Since then, the restricted perfomance message comes on intermittently then turns itself off. There's also whistling noise that increases/decreases with engine revs.

 

I'll check the air filter today, but am wondering what else it could be. I'm also a little concerned by the battery readings, which seem a bit low.

 

Your help much appreciated. I should add there is no Jaguar dealer or mechanic for miles around, and its a 40km round trip to the closest town, which has a Ford dealer.

Hi, thanks for your reply.

 

I included the codes because that's what people ask for. The car is a 3.0 petrol, so I'm not sure what you mean by turbo hose - where would I find it?

 

I took the air filter off to find that it was filthy and looked like it hadn't been changed in  long while, although it should have been last service, and that  the cover hadn't been put on correctly, as in the lugs at the back weren't engaged.

 

That brings me to another question: what is the correct size for replacement? Sites I've checked quote two slightly different sizes, one 298mm in length and the other 310mm.

hi brian 

           the hose for the turbo on the x type and is located under the battery tray,not sure if its the same on the s type, if its loose or split you may get this noise   your best bet would be to ask old peter (user name) he's had s types for a few yrs.

i only said about turbo hose as my x type had the same sort of noise.

hope it helps out

Hi Brian,

 

I have been off line for a day yesterday so i missed your post,

 

I have since checked and it seems that the 3.0 litre s type does not have a turbo charger which is not uncommon in petrol engines.

 

Martin has made a good suggestion, as escaping air causes a whistle.

 

A Ford Dealer would have the diagnostic equipment and Jaguar was owned by Ford for some years prior to TATA.

 

Regards,

 

Peter.

Thanks for the input everyone.

 

I took the car to a garage that seems to deal in specialist cars - as in makes besides the ubiquitous Renault, Peugeot and Citroen - and he located the noise as coming from the belt that drives the alternator. He's going to replace belt and pulleys, plus investigate the other problems and give the car a service. Was going to do the latter myself, but when he quoted me the prices I couldn't refuse.

 

So we'll see what happens. I'm still not super optimistic. The air filter has clean seems to have improved the running of the motor, but the engine warning light is still on.
