Re: Quandry / Query - NOT Porsche related ... need abs help

OK - Issue found , sorted and mot redone ! Faulty wiring (too many Birthdays) on the Rear ABS sensor - so that was both sensors and both bits of wiring on the same side (front and rear) ! What are the odds of that ?. Problem coming and going by jacking up the front - was "caused" by the fa...

Re: Quandry / Query - NOT Porsche related ... need abs help

An ABS fault can be triggered (and stored) if tyre pressures are uneven - a tyre with lower pressure is smaller in diameter than another with the correct pressure, so the wheel turns more often over a given distance. This tricks the ABS monitoring system into believing one wheel is a locking-up, or...

Re: Quandry / Query - NOT Porsche related ... need abs help

Thanks for the response - I'll copy and send on to owner (BIL) and see what that brings. We don't have a tool that will talk to the car , so that makes things awkward. The fact that light clears with sensor not in hub , makes me shy away from bearing / ring related issues. WIP
cheers

Re: Quandry / Query - NOT Porsche related ... need abs help

Not sure I fully understand you. I am NOT sure what the fault code is at the "fail" point. The abs warning light simply comes on . Car is not moving - therefore it can only be sensing wiring or whatever it picks up at a standstill. The wire going to a front sensor was "iffy" - wh...

Quandry / Query - NOT Porsche related ... need abs help

This one has me "confused". Car : circa 2006 Skoda Fabia - 100k miles ABS warning light comes on (inital stationary check) . (Long story in middle here - which involves diagnostics , new wiring , new sensor , etc etc). Jack up the car - (JUST-ie nothing else !) , recheck ... light goes out...

Re: 928

Yip - 25mpg with sensible use ... that can go up to high twenties on a longer run. Then there's the "opposite"..... For Rally use (calculating range - eg fuel needed for a loop of stages) , I used 25 mpg for road sections , and 5 mpg for hard use .... that was 5 !! I reckoned possibly clos...

Re: KS's hillclimbing odyssey

Agreed that high CR can equal higher HP, but it also leads to higher combustion temperatures, which in a VW motor is a problem. I've built 'a few' VW motors over the years, for road, rallycross, rallying and drag racing and for a road engine, around 9-9.5:1 is a sweet spot. If the car was trailered...

I would consider 9.3 LOW...ish ... even for a road engine. Higher CR = Higher power ... simple as that. Could go 10.25 - 10.5 with little consequence , apart from more power.

I hope you replaced the one rotten inner sill that I could see (appears you managed to save one ?)

Re: Time for a mini rant ! (Insurance for a 1.4 Diesel AX)

Just to round this off . I got an online quote from Hagerty , for a more reasonable £185 odd .... Meanwhile , when I got paperwork in from Direct line , it included a "charge" for my normal car policy ... which had NOT been changed. I phone and queried this ... got waffled at , so I asked ...
