    There seems to be lots of threads regarding 'sludge' & the 1.8t engine.

    After reading many posts regarding this problem I went and spoke to my local audi specialist to see if i should change oil pump + oil feed pipe, as a preventative measure.

    Speaking to the mechanic he said i shouldnt need to change these bits as the oil feed has a syphon/filter on which prevents the sludge (if there is any) from causing problems!?!

    He said the only reason i should investigate further or change these bits would be if my oil pressure light was coming on when im on the motorway, as when the car is cruising at around 4k rpm large volumes of oil are getting sucked through & at only this time would i be aware there is a problem!

    I am now really confused about how to tell if my car has this sludge visually & if i should change these parts regardless. (it was on AVS before i changed it to fixed). & if these parts should be changed how much its likely to cost.

    Hi
    I get an oil pressure warning light after I've been on the motorway 30 mins+, do you think I have a sludge problem (I am also 1.8T 190)?

    The fix for it doesn't seem too pricey from what I've seen on here, do you guys think I need to get it done (I'm noticing no other ill effects, just the light coming on and sometimes staying on during long motorway trips)?

    If so, can anyone recommend a good place to get it done in the Leamington Spa area?

    Thanks!

    Oil pressure light should never come on, it's usually the first sign of sludge taking over your engine. If it's really bad already, then it's too late, there's not a lot that can be done about it. Auto-RX and Seafoam are good ways of reducing the effects of the carbon build up. Get some in there sharpish.

    Also, ALWAYS only use fully synthetic oil, and change it regularly, oil and oil filters are cheap and easy to change, it's not worth the risk.

    Get it checked right away, Ive been there and Blown my engine and turbo, Pricey repair but you can nip it in the bud whilst your car is still in motion.
    New Pick-up pipe and you may aswell change the oil pump to. I was quote £450 mark to have that done.....but the Big Bang beat me to it..:sorry:
