Guest sharon Posted January 28, 2004 Report Posted January 28, 2004 having lost the power in my galaxy i forked out Quote
Guest SA Intruder Posted January 28, 2004 Report Posted January 28, 2004 New Turbo? we think not. MAF sensor more likely. Disconnect it and if there's a difference, replace. Loads of previous threads - see if there is one with your symptoms? Quote
seatkid Posted January 28, 2004 Report Posted January 28, 2004 What would be the usual symptoms of a duff turbo anyway? Lots of smoke, noise, possibly a wrecked engine? Not just a power loss - any comments? Quote
Guest sharon Posted January 28, 2004 Report Posted January 28, 2004 WE HAVE RUN THE CAR WITHOUT THE SENSOR ATTACHED FOR THE LAST COUPLE OF MONTHS AND YES IT DOES RUN BETTER, BUT IF THE SENSOR WAS FAULTY ,SHOULD THE DIAGNOSTIC CHECK OF PICKED THAT UP, ALSO WE MENTIONED THIS SENSOR TO THE FORD CHAPPIE AND HE SAID IT WORKS BETTER BECAUSE IT USES MORE FUEL!!!!!!! SCARED STIFF OF BUYING THIS MAF SENSOR AND IT ANOTHER PROBLEM ,IF WE HAVE TO WHERE IS THE BEST (CHEAPEST PLACE TO GET IT)WE WILL TRY CLEANING THE SENSOR TOMORROW AS MENTIONED IN ANOTHER AREA,CAN WE USE WD40 Quote
Dave-G Posted January 28, 2004 Report Posted January 28, 2004 Do you know ANYBODY else with a VW 1.9 tdi? Try a temporary swap. It's incredibly easy...all you need to do is go to a motor-spares shop and get a small set of security torx drivers (security can also mean anti - tamper/tamperproof) cost from about Quote
seatkid Posted January 29, 2004 Report Posted January 29, 2004 WE WILL TRY CLEANING THE SENSOR TOMORROW AS MENTIONED IN ANOTHER AREA,CAN WE USE WD40 NO! (please don't shout!) Use an electronic solvent such isopropyl alcohol, although clean petrol will probably be just as good. (Knew that petrol was useful for something.. :rolleyes: ) Take the Sensor off the vehicle, clean it carefully by washing it through and dry it out thoroughly before refitting (plus leave an hour or two for solvent/petrol to evaporate). Don't poke things into it (cloths/qtips etc) Not guaranteed to work and there is a risk you might damage a good sensor. BUT BEFORE YOU DO THAT...... the diagnostic report was fine but we need a new turbo What do you mean by fine? Did the report say there was low or no boost pressure?That can be caused by a number of things that arent picked up by the PCM diagnostics. Vacuum pipes/boost solenoid/PCM/wiring. Quote
Ivor_E_Tower Posted January 29, 2004 Report Posted January 29, 2004 How did the dealer decide that you need a new turbo? I mean to need a new turbo itself, then there must be vane or bearing failure (or a problem with the casing which would be most unusual). If it's wastegate-related, then you'll just need the appropriate bits and not a turbo. Seems odd diagnosis. Quote
Guest SA Intruder Posted January 29, 2004 Report Posted January 29, 2004 Turbo failure causing power loss is very rare, most Turbo failures involve oil loss into the inlet or exhaust. If you have run without the MAF connected for some time, you have been running on preset safe values and have not been running efficiently. If the MAF was disconnected, how would the diag pick it up? Cleaning the MAF is not generally effective. Replace it after temporary substitution as mentioned above. And never use that garage again. Quote
Guest sharon Posted January 30, 2004 Report Posted January 30, 2004 have found a very very nice man who has a maf sensor in stock and is prepared to put it on and let us test drive the galaxy to see if this sorts out our problem. fingers crossed, watch this space. will post results saturday evening. <_< Quote
Guest Shazza Posted January 31, 2004 Report Posted January 31, 2004 The MAF sensor is Mass Air Flow, right? Is that the same thing as the MAP sensor, which I thought stood for Manifold Absolute Pressure? When my power went last year, we were told it was the MAP sensor and Fords changed it under the warranty. When a friend bought a Galaxy and hers wasn't pulling properly, I suggested it might be the MAP sensor, and it was. Seems to be a common problem in the Galaxy. Shazza Quote
seatkid Posted January 31, 2004 Report Posted January 31, 2004 No, not the same things. MAF sits after the airfilter but before the turbo and measures the mass rate of air into the engine. The T-MAP sensor sits after the turbo (and intercooler) and measures the turbo boost pressure (and air temperature going into engine).MAF is used in the calculation of amount of fuel required to be injected. MAP is used to control the turbo pressure via the pressure solenoid/waste gate. Quote
Guest SA Intruder Posted January 31, 2004 Report Posted January 31, 2004 No, they all have MAFs not MAPs to measure air volume. They is an inverse "MAP" in the turbo pipe that measures boost pressure - not normally a problem part. I would hazard a guess at 100:1 on MAF. Quote
Guest gemineye Posted February 2, 2004 Report Posted February 2, 2004 My power loss problem is sometimes happens from start off from lights, picking up power as it goes along but is a pain with traffic behind. Quote
Guest sharon Posted February 4, 2004 Report Posted February 4, 2004 :blink: total success, car runs great now so i would like to mention apollo garage, lichfield ind est, tamworth, staffs, fitted in 5 minutes and cost Quote
