C5 (X7) Component Failures /Faults / Replacements Polll

X7-Saloon.png X7-Tourer.png

This is just an experiment to see if this is something that would be of interest to members and could be extended to other models. There would seem to be common and not so common part failures, so I thought an ongoing poll may be useful for members to record...

Attention C5 and C6 Owners

Another member of the Forum recently had his C5 X7 LDS tank explode at a recent tyre fitting session, when the vehicle was lowered back to the ground.

For those unaware, the C5 and C6 should have the suspension raised to the highest position and the LDS tank cap removed whenever the vehicle will be lifted off the...

A burglar broke into a house one night. He shined his flashlight around, looking for valuables when a voice in the dark said,

'Jesus knows you're here.'

He nearly jumped out of his skin, clicked his flashlight off, and froze.

When he heard nothing more, after a bit, he shook his head and continued.

Just as he pulled the stereo out so he could...

Hi All,
Seems I have a new neighbor with a lovely silver Xantia with personalized reg plate.

Have not seen up close yet, so not clear on the specifications, also due to vague parking arrangements I don't know exactly which house is theirs either.

Is this anyone on here living in HP1 area with a Silver Xantia on a personal plate?

Admins, sorry...

A post from a member who has likely suffered a Hard Drive failure on his NG4 Navidrive 3D system has prompted me to re-double my efforts in finding a possible pre-emptive solution to Drive Failure. The same can be said of the RT4 system with a HDD, although these units seem to have more issues than the NG4. Although the principle is the same for...

Any more/amplification?
