The air dryer is inside the air supply unit is it not, didn't think you could buy parts inside this unit? 2004 black Vogue TD6

Howdy again !

I was told the dryer is effectiveley a filter and as such should be a service item (but it isn't). Perhaps if it was there wouldn't be so many compressor problems ?, but I'm not suitably qualified to comment . . . . . Where do you go after one of these . . . ?

Mine came up with that fault to on the dash to,

In a panic took to local r,r guy about half a mile away

Now if what he says is true or not i will never know!!!
I have not used it for a whole week or more and its been minus temps at night!
He put it down to just that not enough charge in battery to power it up and as we were talking and car ticking over for about ten mins ...Out it went , all lights off no warning lights on dash etc

Took out yesterday and today for a bit of a run and its fine......I hope.

WHATS THINK ??????????

Thats a bit of a hijack sorry!!

it can be the battery ...you really need to get the fault codes read, cleared and see what occurs again

I had HDC inactive + air suspension inactive on/off for about a month, finally got it into a specialist and it turned out to be a wheel speed sensor - £20 part sorted it cheers
