SCV time ?

PostPosted by sich1 » Sat Dec 10, 2016 11:50 pm

just what you need around xmas......

on the return leg of a trip to visit my dad today i began to notice some small
hesitations when at cruising speed. nothing on acceleration.
then i get a couple more, then a EML light! no limp mode though.
pulled into the next garage and got the code reader plugged in, P0627.
i seemed to remember that it may be scv's and looking on here i think it probably is.
lack of acceleration above 2.3k res.

looks like £200 quid for new ones...damn

cars now done just short of 90k which seems to be the fail point on other 4.2's as well.

any advice etc hints on fitting most welcome

are there any other things that give similar codes?

Nope. Cough up bostik pockets.

You can sometimes recover them with a good wash off in degreaser or IPA. Keep everything dead clean. You can reach under from above or up from underneath. Make sure your Allen key is right in the screw or it will round off. Clean it right out first.

This might help with other causes, but as Anchorman said it is more than likely the SCV.

Don’t soak them long in IPA though Jase. And keep in mind it might not work!

lol ipa...what a waste of good beer :shok:

i was running a can of bg224 through the system when the fault occured.
was fine the first 145mile leg, then the return leg thew up the fault.
i would have thought the bg224 would have given them a good clean and wash out.

would this info change the verdict any?

Only in that if they won't clean you need to change them.

well, i think this has confirmed the need to cough up for a new set now.

same trip as before, 2 x 145 mile runs.

a couple of hiccups on the way down and on the way back i was stuck at 70mph most of the way.
no acceleration on any hill which is annoying as i like to keep a steady speed. just the oddl burst of power then nothing again.

has anyone tried Thomasdieselparts on the bay before?

http://www.ebay.co.uk/itm/Denso-Diesel- ... SwHnFVxNJm

just nipping around town was also no bother before, but now i have the same lack of power and hiccupping just dodging around.

any clue what size the hex key is i need?
