    hi all,

    audi a4 b8 2008 2.0 tdi 143hp caga engine

    137k miles, castrol edge only, well driven and well maintained

    2 days ago, I got the low oil pressure light on dashboard. I was on a busy road, hence I drove for another 2 miles/5 minutes before shutting the engine off. I then called green flag, who took me home. it turns out the oil pump module on this engine is crap, as audi thought it was wise to connect some of the most vital parts of the engine with the crappiest quality metal out there.

    long story short, I'm getting my hands dirty and changing shit. initially I thought it was a matter of removing the undertrays, removing sump, removing oil shaft assembly, replacing old parts and puttin things back together. turns out you must remove the subframe... really???

    who's done this on this car before? any special tools I need? can it be done with the subframe in place? how do I undo the bolts holding the sump in place (the ones from the gearbox side)? some people say you don't need to remove subframe, others say you do. some say you must remove gearbox to get access to bolts, others say you don't.

    anyone here who has a bit of knowledge they can share? I would have to pay a garage £300 just to look at it (if the turbo/main bearings are gone), so why not buy tools/bolts/silicone with that money and attempt myself? I already have all the other tools, unless I need an engine jack.

    thanks,
    chris

    That’s for the B6/B7, not related to my car. My car already has a delete in the way that it doesn't have any chains. The weak link in the new set up is the oil pump drive shaft. You can’t delete that, just replace it with a proper version, which will make it indestructible and the engine bullet proof.

    Fixed mine at ring engineering in hayes for £780 (incl. VAT). Engine runs like a charm. Was told there was absolutely no damage at all and that my car was the only lucky one. I use duralube, which I’m sure saved my engine. I heard stories of peoplerunning on no oil for tens of miles without engine damage, all because of duralube.
