Golf TDI strange behaviour
Discussion
Been having some strange things happening to our Golf TDI Sport reciently, and following a visit to our dealer, nothign was picked up in the fault codes, and they seem not to beable to replicate it.
The problem is that when driving, and cruising with the throttle being fethered lightly, the car literally "hiccup"'s before the turbo spools up and she accelerates. Its not turbo lag, there is no power for maybe a second, before she accelerates. Other times, this pause isnt there, and the acceleration is hardly noticable.
It seems to happen at all different rev ranges, so I dont think its a flatspot.
Interestingly enough, comming back from a 200 mile run a few weeks ago, cruising at 80mph, pressed the throttle to the floor to accelerate and nothing happened !!... backing of the throttle and trying to acce;lerate actually resulted in slowing down!!.
Made it to the services, engine off, checked the intakes and hoses, no signs of any splits or loose connections, jump in car, drive off... problem no longer present... Very Strange.

Hi,
never had the hic up problem you mention, but have had the problem when crusing above 70 and then trying to excelerate you get no power.
Once this problem kicks in, when i get it you get no turbo at all in any gear, only way ive found it to get some power build up is to put in a higher gear than normal insted of revving the tits off it, this seems to build up the power more gradual and you end up with the mph creeping back up.
had this problem in a 2002 golf gt tdi, changed turbo loads of other bits, sent to vw stil couldnt sort it out, eventually sold car way it was.
now have a 2006 A3 tdi with the dsg gearbox and the same problem has started again, not sure if anyone else has had this problem and fixed it??? with the A3 it doesnt happen alot, once a month at most.
Did hear from a friend that it can have something to do with the brake sensor.It sends info back to the cars ecu and for some reason it can affect it with this problem we have had.
Its a cheapish fix, so worth trying first, think most indy vw garages will know about it.
hope this helps you out.
