I still think it' the T-MAP sensor!! Mike

Well I always wondered what that black thing was... Looks like I'll be finishing work early tomorrow to investigate... Will ley ya all know, and cheers for the info!! Mike

Ed, Fraud quoted me

Hmm.. Will reset the ECU tomorrow and clear the faults.. VAG-COM to the rescue lol.... Will try it out later on, but it will be 10pm before I am home tomorrow... Mike

Defo not the chip - has been off and on about 6 times in the past few months - ie each time it's been to a garaga... Still get same problem, but takes longer to get there!! Mike

Right - after a good knuckle scraping, in the rain and the dark... Torch in hand... Just pulled off the pipe and went for a spin... Did about 6 miles on normal roads, giving it some clog once warmed up - seemed as good as it was before the fault.... Got to the motorway and hoofed it up the slip road .... Still going well... Got to about 95'ish (haven't been able to do that for a while) and .... Yep, loss of boost... Killed the ign at the roundabout, and all back again, gave it some on the way back, but no loss of boost, mind you only got upto about 60, although it would redline in 3rd, and hit 4k in 4th easily when held in Tip mode.. So... Much better, but still not 100%.. Anyone else care to give it a go and comment? Mike

DMcB, it isn't the boost pressure control valve.. Nor the MAF, and by the sound of it not the accelerator pedal either.. I am thinking more and more that it's the T-MAP sensor, Seatkid, what do you reckon if I join together the VAC and OUT lines of the boost pressure control valve??? Thereby removing it's influence on the vacuum?? I think my turbo is fine as it boosts ok, just something somewhere is calling a halt to the process, and (apparently) opening the boost control valve... Another idea I have is wiring a 12v led to the connector on the boost control valve (correct polarity of course) and then seeing if it is energised or de-energised at the point of the problem happening - may give a bit more in the way of tracking it down.. I really do think T-MAP at the mo though... Will give tour other suggestion a go too... Does anyone know if the boost control valve operates on a variable voltagepulses or is just on/off? Mike

Right an Update - A known faulty MAF arrived in the post for me today - many thanks Seatalhambra!!! Anyway, swapped it and the car is now gutless, and still has the boost cutting out at 300 rpm in top.. So I thinks the MAF is ruled out as ok.. All things really seem to be pointing to the T-MAP sensor..... Also I am gonna post this in the 3 similar threads that are going at the moment, as it's getting hard to keep up!! Can a mod possibly combine the threads?? http://www.fordgalaxy.org.uk/ford/index.ph...=15&?do=findComment&comment=40532 http://www.fordgalaxy.org.uk/ford/index.ph...&hl=boost&st=15 http://www.fordgalaxy.org.uk/ford/index.ph...topic=5735&st=0 All the above threads seem to be about the same problem..

Approx 10deg air temp and max coolant temp of 85 deg... But some get 11 or 12 deg, yours is trhe first I have seen @ 13 but I wouldn't worry about it.. MIke

Just so happens... http://img371.imageshack.us/img371/8522/screenhunter0579it.jpg But I can't take all the credit - simply copying and pasteing lol Mike

Dave, although I am biased... I wouln't bother with any of the bulbs on Ebay, they burn out quickly, and are no match for Xenons. Also make sure any bulb is 55w max, is filtered to make it safe for plastic lenses, and is E rated for road use.. Mike

Mine ignore my bar - but don't like it when it rains lol.. Mike

Ed, was the boost pressure sensor (T-MAP) in the manifold pipe near the battery changed, or the boost pressure control valve/solenoid (behind the engive on the bulkhead) I am pretty certain that the former is causing my problems too... How much did you pay (if that's what you changed) Mike

LMAO @ Seatkid... Oh btw Russell, I'd consider myself fairly upto speed on Auto boxes, having had 3 lololol!!! Mike

Hi and welcome... If the cap you are talking about is yellow with red writing, then it's coolant... The Oil cap sgould be black with yellow writing (if memory serves correctly) and it's a simple turn anticlockwise to remove.. HTH Mike

Aaaaww Schucks! :( Lol Mike

Quote.... "The turbocharger is an integral component of the exhaust manifold and although it is possible to separate them, they are not supplied separately and should therefore not be disconnected. The turbocharger consists of two elements, a turbine and a compressor. These elements are installed on a single shaft and are contained within a housing. The turbocharger bearings are supplied oil from the engine via the oil supply tube. This is returned to the oil pan via the oil return tube. The turbine uses the pressure of the exhaust gas to drive the compressor. The compressor draws air through the air cleaner and forces it into the intake manifold. The turbocharger vane adjustment vacuum diaphragm unit adjusts the turbocharger vanes according to the vacuum supplied by the turbocharger vane adjustment solenoid valve. The turbocharger vane adjustment solenoid valve is controlled by the powertrain control module (PCM). The actual turbocharger boost pressure is regulated by the adjustment of the turbocharger vanes and so eliminates the need for a wastegate control valve. The turbocharger vane adjustment vacuum diaphragm unit is preset during manufacture and must not be tampered with." And "Principles of Operation - Vehicles with 115 PS Diesel Engine The turbocharger is designed to improve engine induction and engine performance. The list below details the concerns relating to turbocharger performance. l High engine speed produces excessive turbine speed and therefore creates excessive turbocharger boost pressure. l Low engine speed does not produce sufficient turbine speed and therefore not enough turbocharger boost pressure is achieved. The variable turbocharger does not have a wastegate control valve. Instead, it has variable turbocharger vanes which are located in the turbocharger turbine housing. The turbocharger vanes act as the control for the turbocharger boost pressure. The variable turbocharger produces its full turbocharger boost pressure over the entire engine speed range, not just at high engine speed. This is achieved through the adjustment of the vanes and the resulting change in the flow of the exhaust gas. The speed of flow of the stream of exhaust gas is increased independent of engine speed by varying the intake cross section in front of the turbocharger turbine. This drives the turbocharger turbine faster. The higher turbocharger speed produces a high turbocharger boost pressure at all engine speeds. The powertrain control module (PCM) controls the turbocharger vanes. REFER to WDS to diagnose the turbocharger vanes." http://img44.imageshack.us/img44/7017/screenhunter0517pg.jpg http://img44.imageshack.us/img44/5424/screenhunter0520xw.jpg At low engine speeds the PCM actuates the vane adjustment solenoid valve to enable a vacuum to be applied. The vacuum diaphragm unit moves the adjusting ring so that the vanes are set at a shallow angle. The shallow intake cross section this creates for the stream of exhaust gas allows the turbocharger boost pressure to build up rapidly and easily at low engine speeds. http://img78.imageshack.us/img78/9536/screenhunter0562ej.jpg Mike

Xenons do take approx 10- secs to reach full brightness after switching on... I don't find this a prolem, already having fully warmed up dipped beams.. Mike

{Ian... Constructive chat, hopefully... Have emailed you my addy Look at these, may give you some more info.. http://www.fordgalaxy.org.uk/ford/index.ph...wtopic=3417&hl= http://www.fordgalaxy.org.uk/ford/index.ph...wtopic=3800&hl= http://www.fordgalaxy.org.uk/ford/index.ph...wtopic=3618&hl= http://www.fordgalaxy.org.uk/ford/index.ph...wtopic=4483&hl= and http://www.fordgalaxy.org.uk/ford/index.ph...ic=4231&hl=auto Cattch ya soon.. Mike

Are you sure it's the wipers? I had a similar noise on mine - it was the two panels that fit around the wiper shaft - the plastic clips had broken and they were rattling at speed, new clips were pennies and cured it immediatels. Mike

Mine has had 2 boxes and 3 valve bodies!!! But - it ain't a VW box, it's made by Jatco - Japanese Auto Trans Co, and they fit the same type of box in the rover 74, MGF and others, they are all crap too! Mike

Dave, I only have 1557, Boost pressure control POSITIVE DEVIATION... Mike

Davem, guess you didn't see my post yesterday... http://www.fordgalaxy.org.uk/ford/index.ph...opic=5699&st=15 Have been on to Ford and told them they had misdiagnosed the fault and I am not paying for the time they took to do so... Guy apologised and is putting their so called "master tech" on to it on Tues, no charge for the diagnostic or investigative work... I still think it's a T-MAP sesnor prob though.. Mike
