Jaguar problems

[Olds]

###### Jag
Put the jag in for MOT today and received a call saying it had blown off one of the coolant hoses!
No idea why this should happen as I've not touched the cooling system since replacing the cam chain tensioners last year after one of them decided it was a hand grenade
Brought the car back, put the hose back on, filled with fluids and ran the engine. No problems . Cleaned off all the coolant from the engine bay and now I have restricted performance warning come up! On checking the obd, seems the right hand bank, knock sensor has gone duff
I can only think, that washing off the coolant from the warm engine, caused thermal shock to the sensor.
Should have kept the old V8 landy. No ECUs or sensors to go wrong. I got rid of the wrong vehicle.

Clean the plug for the sensor with wd40 or the like. Coolant probably got in there and fouled the connection
At a guess

Thanks chewie but have already dried out the connection with an airline and used wd40.
Seems that as the sensors get older they become prone to moisture ingress.
The sensor for my vehicle would cost about £70+ each ( 100+ aussie dollars) but for the year later about £20. Same thing but the cheaper one has a longer lead Guess which one I'll be fitting

I hate modern cars with thier over elaborate electrical systems! I really fail to see the point.
Last week I suffered the inconvienience of an intermittant starting problem on my old Rover. Eventually intermittant turned into permenant and I had no choice but to call out a man with a magic box that identified a problem with the ECU communicating with the immobiliser.
Suffice to say that a large amount of cash needed to change hands in the hope that a `minor` reprogramming of the ECU would cure my ailment.
I declined the offer and accepted a different one from a local salvage yard instead. Now of course, I own an even newer car, with even more dubious electrical circuits, and every one of them ready and willing to fail me at the most inconvienient time!

Yep Tbone. It's getting ridiculous.
Cooking the sensor seems to have cured the problem for now but while putting it back I lent on the plastic bleed pipe from the thermostat housing to the expansion tank and it broke . Local dealer (Harwoods) doesn't have one but will get one sent up, from their Chichester branch, for 3.00pm today. Total cost £7.80p

Tim, I long for the days when I could open the bonnet of a "dead" car and almost guarantee I could bring it back to life, now, well I don't even open the bonnet as there's very little point! indeed I'm not at all sure where the bonnet catch is on my current motor! For the first time in my fairly long life, being a member of one of the breakdown agencies seems an imperative,...bah, humbug.... ...Morrag

It was suggested to me that an ej20 would be better then a Vw lump for resons including the electronic control
Shortly after i discovered the joys of being stuck with a dead car due to a bad sensor/plug
It seems that they foul up more then anything else these days

Fixed the bleed pipe but the senseor warning has come back . Not going to touch it now until after the MSVA. Too much other stiff to do.
 I put my daughters car in for MOT yesterday and it passed so for a while I will be driving around in a Fiat Panda.
