davidwort 0 Posted August 28, 2008 KR 067 906 171 9A 026 906 171A Quote Share this post Link to post Share on other sites
Zeal 0 Posted August 28, 2008 nice one, much appreciated, does that mean the 9a one is different to the kr or are they interchangeable? Quote Share this post Link to post Share on other sites
davidwort 0 Posted August 28, 2008 nice one, much appreciated, does that mean the 9a one is different to the kr or are they interchangeable? They look the same (I've got a KR one on my 1990 16v and a spare audi 80 one (2L 16v same as 9a one) and I'd imagine the 2L one just sprays a bit more fuel. As I have 2L block but with a KR head and injection system I'd say the KR one works fine on a 2L, but I'm not sure if the KE-jet system on the 9A runs at slightly different fuel pressures or how that might affect the electronically controlled valve. BTW, no mk3 uses K-jet so won't have a cold start injector. Quote Share this post Link to post Share on other sites
Zeal 0 Posted August 28, 2008 thanks again, good information, what it is, i'm looking at buying this to replace mine, the seller claims it's a mk3 2l 16v cold start valve/injector and he plugged it into a 1.8 16v corrado and it fits the electrical side of things, any ideas? http://cgi.ebay.co.uk/VW-Mk3-GTI-2l-Col ... 286.c0.m14 Quote Share this post Link to post Share on other sites
davidwort 0 Posted August 28, 2008 well, firstly that is a cold start valve but mk3's don't have them regardless of engine, lol and secondly are you sure yours is bust? and thirdly, I've got a 2L one you can have for a fiver plus a couple of quid postage, but like I said, although they look identical, I've no idea what's different between the 1.8 and 2L parts, I would try it on my engine but I think the paper gasket would fall to bits.

From reading on hear i guess it could be the ignition switch (although we tried another) or a burnt out ecu? god knows really, i think he's as baffled as i am, the fueling and spark are all fine. thanks, i'l take you up on the offer of the cold start valve if he thinks it's ok, he did mention that quite a few cars had the same part, and gsf website says it fits most 4cyl audi/vw. i'l ring him tonight and let you know Quote Share this post Link to post Share on other sites
davidwort 0 Posted August 28, 2008 the KR CSV is specific to the KR engine, which you'll find in golf/jetta mk2 16v's, passats and corrados. I don't think it's your CSV, they're only used to give a burst of fuel for starting and possibly full throttle, they're pretty crude as they simply squirt fuel into all four manifold runners at the same time, it should run fine without one connected at all really. It's more likely you have a dodgy Warm Up Regulator which I think you can do a basic test on with a multimeter to test resistance across it's electrical connections. Failing that he needs to do a full fuel system pressure check which means conecting up a pressure meter to the metering head etc with the correct fittings. Other things to check are injectors for leakage and spray pattern and the usual vacuum leaks that can be anywhere in the inlet system, vac lines, gaskets, rubber boots on main inlet etc. although I'd expect that t ousual cause idling problems when warmed up too.

Zeal 0 Posted August 28, 2008 cool, thanks, I'm sure we came to the conclusion that it can't be the csv now you mention it, :oops: I'm not sure how i got back to that! I'll let him know and see if he can do the tests. why are corrado problems constant and never simple??? I've already changed the starter and alternator with reconditioned items after a friends recommendation and they have both failed, so he's putting the old ones back on! :brickwall: my corrado's such a money grabbing bitch! but I'm not giving up.

Zeal 0 Posted August 28, 2008 £270 quid for a new one! it would be wouldn't it. Quote Share this post Link to post Share on other sites
davidwort 0 Posted August 28, 2008 is that the price for a WUR? wouldn't surprise me, but they are pretty reliable generally and a second hand one would probably do fine. Quote Share this post Link to post Share on other sites
Zeal 0 Posted August 28, 2008 yep that's the price quoted on ecp, although they have no stock, I'll have a go at finding a second hand one, but finding any corrado part in my area is a complete nightmare. Hopefully it will not be the wur. I'll have to wait till Friday to find out because my mechanics having a few nights off. Quote Share this post Link to post Share on other sites
