nfbr Posted May 13, 2007 Report Share Posted May 13, 2007 (edited) Probably the N75 valve you need to replace... This is the "Boost control valve / solenoid"Like i say - I've had the engine in more bits than you could count, and i still have not found any form of Dump Valve or Recirculating system... You can't run a dump valve on a diesel because it does not go below 0psi boost... A dump valve operates on the fact of the system going below 0psi, i.e. Into negative boost, or Vacuum..."Diesel Dump Valves" Operate on an electronic pedal switch, because the engine has nothing to open a dump valve with.also - You obviously can't tell the difference between Caps and lower case. NFBR is someone else... defo not me.P.S. I apollogise for my ill found knowlege on the engine that i've practically rebuilt with my own bare hands... Perhaps i lost my dump valve when i built it back up... Edited May 13, 2007 by nfbr Quote Link to comment Share on other sites More sharing options...

g-man85 Posted May 13, 2007 Report Share Posted May 13, 2007 Right to add some of my thoughts. As far as i'm aware these TDI engines operate as nfbr says. Just from my boost gauge it never boosts below 0psi, unlike petrol turbo cars which you often see the boost going into negative pressure on the gauge (hence the dials are designed to get into negative boost)There's a N75 valve and something like an N18 valve?? I've followed all the tubes/connectors but I agree there is no such dumpvalve system as I have seen on my bro's old mk4 gti 1.8 turbo.The turbo dump valve uses a cable running from the throttle positioning sensor. Its a little black box you're meant to connect up.Which part is it that you're meant to be fixing? Just out of interest.Here's two sketchy ETKA diagrams for the 1.4 TDI engines (AMF) for the turbo connections and the charge cooler: border="0" class="linked-image" /> border="0" class="linked-image" /> border="0" class="linked-image" /> border="0" class="linked-image" /> border="0" class="linked-image" /> border="0" class="linked-image" /> Quote Link to comment Share on other sites More sharing options...

nev Posted May 27, 2007 Report Share Posted May 27, 2007 (edited) I found it look, that dump valve thingy seat mentioned. lolIt could be the one I put there. Yes I know it does naff all for the performance but I don't mind I like the noise it makes.There easy to fit and if you put in a switch you can shut it off any time so it is like it was never there.If you want power flick the switch to off and if you want noise flick the switch to on.So in the on position all the chavs go WWOOWW when you drive past them sitting on the seats in the main street wishing they had a car that did that. lolIts all good fun and at the end of the day. Its night! border="0" class="linked-image" /> border="0" class="linked-image" /> Edited May 27, 2007 by nev Quote Link to comment Share on other sites More sharing options...
