Speed/Cruise Control Fix...

Postby SimonR » Wed Apr 01, 2009 10:01 am

Just in case anybody has the same fault I thought I'd post this:

I stored my car for 18 months and after I got it going again the cruise control did not work any more. I spoke to Chris at KWE and he said that it was caused by the fact that the rubber bellows were no longer airtight, meaning that the vacuum was leaking.

His fix was to remove the bellows, disassemble them, clean the metal plates at either end and then silicone seal the bellows to them at either end.

It took about 30 minutes in total and I can now report that the speed control is working as it should.

This relates to the early kind of bellows - it's a rubber cylinder about 10mm in diameter with a steel plate at either end, one has two air valves attached, the other end is attached to a cable.

i fixed mine , almost like the method above

i bought a new bellows from America, and then followed the same steps as above

just a note, the bellows isnt supplied as a separate part from Jaguar, you have to buy the whole lot

the american OEM replacement was £10 ,

this was last year though
