Hiccuping Tdi

[marinabrid]

hi all, wifes motor, tdi 110 on a 98 just had my once a month drive in it and i notice that when engine warm normal temp i put foot down at 40 mph in 4th gear no under load much and for a couple of seconds hiccups occoured. on the car that is. tried it in lower gears right up the rev range and nothing.

behaved fine from then on. took it out later and tried again let it slow right down to 35 mph then floored it in 4th did this about 10 times and got :unsure: 1 hiccup then fine.

could it be the start of something or is this a common thing with these, though it not happedned in 2 years. thanks all

Try draining your fuel filter, hiccups are a symptom of water in the fuel, which is normally trapped in the fuel filter. There is a plastic tap under the filter.

 

Fuel filter is normally changed every 20,000 miles

i changed the fuel filter aboot 6 months ago about 2000 miles couild water have got in by now ? what do i do ? just unscrew the drain screw for a short while ?

Its a squeeze to get at the tap,so loosen the strap that holds the filter, lift the filter a bit, get a cup or something under the filter (if you dont want diesel on your gearbox) then with your fingers undo the plastic wheel under the filter (it also has a little crank handle moulded in it). You have to undo it a fair way and you'll get your hand covered in smelly diesel. When I did mine only an egg cup full of fuel came out but the hiccups stopped.
