Should this be a fresh post as it may detract from the OE post.? The car is a Sharan TDI belonging to a financially challenged friend -Its left hand drive and in france Engine AHU, first reg 17th august 1998. Car vin number is: wvwzzz7mzxv013***. Would this be an NVT turbo?, on the turbo plate is 11989/600-30K J1075/1820. -Could be the odd incorrect number due to reading in a mirror lying on the garage floor upside down with head and arm jammed round the driveshaft. . I now have the car with me today and have spent this morning on it. Road testing last week from cold it dropped power for the first time part way up a hill after a 20k drive (thrash). I came back ,had a quick look, replaced a section of worn vac hose (under bonnet - to MAP sensor in ECU) Road tested again and power dropped off again at exactly the same place as before (sneaked another scan,clear and res-can with original fault code reappearing), back to base,another look round, disconnected and reconnected turbo valve and all the other sensors I could easily reach. Road tested again and exactly same result. Working on it again today I road tested it and exactly the same as before but found if I switch off then back on (read to try this on forum) then it is ok until next high boost demand then power goes down again. When it does this it is instant and very obvious, feels just like a turbo hose has blown off I then replaced more vac hoses as ness, had the codes read, cleared and read again comes up with 65535 035.on one scanner and "permanent ecm fault" on another - neither proper VW scanners. Asked for turbo boost readouts but circumstances (garage boss came back) and the only one we had time to record was "desired boost 795, -"boost pressure 979". Seems a fair difference does that confirm it's overboosting? Got back to base and then checked the turbo operating valve which gave the correct figures according to Autodata Another problem I encountered was the engine cut out as I braked to 10kph to turn down a side road after driving about 30k (the last 2k up a long uphill gradient at only 65/75kph due to the power loss). Wouldn't fire at all on the first attempt to start, fired intermittently after a while on the second attempt, better on the third attempt then eventually picked up properly and revved ok. Sneaked probably the last free scan ever, no other fault than the previous one still recorded.THe owner says it has done that before and is doing so more frequently.Last thing I did was replace the fuel filter I had ordered days ago (this is france). I did notice the fuel pipe in at the filter was perished / split so I shortened it slightly and do wonder if it was drawing air in before and causing a problem. Sneaked the very very last free "clear and reread" scan - no change, same fault recorded Logic tells me ECU wants replacing but they are expensive and look a b*ga to get out and I have read that others have done that and been wrong Just read the new post and will check actuator tomorrow but could do with knowing how to ID the turbo type if the number above can't and also does the ecu control limp mode by reducing turbo boost or fuelling ????. Got involved with this to help out and I obviously know all about VW's as amongst my fleet I have a golf mk2 diesel na and a passat '93 tdi (GO SLOW BUT GET THERE CARS)!!!
