Ric, if I am understanding correctly it is the hose that connects with the "flame arrestor", it's part of the PCV system.

Fault code P1178Rich Fuelling Trim, Long Term (AMFR)Check for manifold air leaks, rectify as necessary Check for recorded MAFS fault code, rectify as necessary Clear fault code and perform service drive cycle to verify fault cleared Contact Jaguar Service Hotline if fault still present.

Taken from the Jag service manual.

If the brake lines and fluid is clear then you may have to look at the brake booster found at the other end of the brake pedal under the hood...

if it is displaying a security code on the face, you will need to call a jag dealer with the vin number handy to get the 4 digit code. than enter that code using the "preset" buttons

I bought a 1991 Jag XJ6 and the stereo was locked. I called the Jaguar dealer and spoke with a person at the parts desk (Cole European in Walnut Creek CA). He asked for the vin# and looked up the code. I don't think you can plainly see the code in your vin# because my code does not exactly match any of the numbers in the vin#. He did not charge me for giving me the code number, but you might have go in with your license and registration to prove the car is yours.

You'll need to call a Jag dealer and prove you own the car legally. Be prepared to show a bill of sale, a title, and the vehicel's VIN.

to get to it you will need to remove your glove box. I should be obvious how to get it out from there.

call a jaguar dealer give them the vin number an they will give you the code
