SportingShooter 0 Posted April 9, 2008 Report Share Posted April 9, 2008 My old man had the same trouble with his passat 1.9 tdi. it just wouldnt pull in the end, turned out the turbo had gone and subsequently ruined the engine. nos? nos and diesel, make an interesting bang im sure ss06 Quote Link to post Share on other sites
BlueCoyote 0 Posted April 9, 2008 Report Share Posted April 9, 2008 (edited) husband (who is a mechanic )says could be water in the fuel - happens with diesels - he says replace all fuel filters. could be as simple as that. and dont buy diesel from the last place you bought gas because they could be mixing water with the fuel. could also have lost compression - depending on age - if its new then its probably just fuel.

Rabbithunter 456 Posted April 9, 2008 Author Report Share Posted April 9, 2008 the van isnt turbo....... if it was,,, then i would be worried Quote Link to post Share on other sites

RatSnatcher 0 Posted April 9, 2008 Report Share Posted April 9, 2008 Has this just started being sluggish or has it always been sluggish? If it is the latter then look at the picture I have posted and see the black line at the top I have drawn........ you can turn the midrange power up by removing the metal tab that is on top of the unit where the line is drawn ....prize it out with a small screw driver and mark the screw head with tippex or a blob of paint for reference .......undo the nut and turn the screw half a turn at a time till you notice a power increase, dont over do it 1 full turn will be enough....and dont forget to tighten the nut after you have made the adjustment it works a treat on non turbo's Quote Link to post Share on other sites
gsi2000stokie 5 Posted April 9, 2008 Report Share Posted April 9, 2008 if its not a turbo then stick one on. or drop one of these diesel engines in but youll have to mix a bit of top fuel in with it. but it is a diesel name="wmode" value="transparent"></param><embed src=" type="application/x-shockwave-flash" wmode="transparent" width="425" height="355"></embed></object>"> name="wmode" value="transparent"></param><embed src=" type="application/x-shockwave-flash" wmode="transparent" width="425" height="355"></embed></object>" type="application/x-shockwave-flash" width="425" height="350"> Quote Link to post Share on other sites
Rabbithunter 456 Posted April 10, 2008 Author Report Share Posted April 10, 2008 ratsnatcher,,, its always been sluggish. do i have to dis-assemble anything to get at that part of the pump ? is there any dangers in doing this? Quote Link to post Share on other sites
DDD 4 Posted April 10, 2008 Report Share Posted April 10, 2008 If you adjust the screw as described without doing any other changes all you will be doing is throwing unburnt fuel straight out the exhaust, hence why you get black smoke on so called "tweaked" engines. All depends what van it is & how much you are carrying! A bit more info would be good. In fact, I would like to see you do the suggested adjustment if it's non turbo!! The bit on top of the above Bosch pump is the boost control unit, under that there is a diaphragm, spring & an odd shaped cone. For more tweaks................become a mechanic, that's why we spend years of training!! Quote Link to post Share on other sites
RatSnatcher 0 Posted April 10, 2008 Report Share Posted April 10, 2008 You dont un bolt anything.....where I have drawn the line on the pic is a blanking tab as I say remove the little metal tab at the top of the unit where the line is........do this and take a pic and stick it up on here for me to see what setup you have .....all you are doing is allowing a little more diesel through the pump the main thing is not to over do it, 1/2 a turn then take it down the road and test it, if it feels no different try anothe half a turn, but no more, the paint or tippex is to mark a reference of the original setting...

abley 0 Posted April 10, 2008 Report Share Posted April 10, 2008 I'd do the simpler things first, changing fuel filters and flushing tank etc, before tinkering with the pump. No offense DDD. Also what mileage is on the van. Any other symptoms such as using oil or water. Quote Link to post Share on other sites
DDD 4 Posted April 10, 2008 Report Share Posted April 10, 2008 your right DDD but its has nothing to do with the turbo this can only be done on Bosch pumps....... So by your reckoning this has nothing to do with the turbo? I reckon you should go & look under your bonnet & you'll find that the boost pressure acts on the top of the diaphragm that is in this chamber, overcoming spring pressure & giving you the extra oomph. Where is this boost pressure tapped from? That'll be the turbo then OR If you have a newer car with electrickery controlled via the ecu, you'll find that there is no pipe to it & it's all done off sensors to activate the boost electronically, using MAF sensors, etc etc etc. Now then, who wants a lesson in drive train properties & epicyclics!!!!!!

I dont need a lesson in any mechanics from you, you dont know much mate obviously heres a link for VW Bosch adjustment.......... if you look clearly its from a Bosch publication see left hand corner of the link ......... http://www.elektro.com/charlie/vwdiesel/ oh here is another........ http://www.vwdiesel.net/phpBB/viewtopic.ph...adca147577d33a6 oh and another on a transit ...........non turbo http://fordtransit.org/forum/viewtopic.php...p;sk=t&sd=a Funny there even doing it on Dodge Rams..........http://dodgeram.org/tech/dsl/more_power/Power_ve.htm So maybe you should check your drive train properties & epicyclics!!!!!! and stick to your Haynes and clymer manuals....... Rabbit hunter if you look at the transit link I have posted it has pictures to illustrate, I have done this and gained a lot more power especially up hills Quote Link to post Share on other sites
