Octavia Mk2 Bottom end gone ?

    I have a 05 DSG Octavia 1.9TDi that was having issues starting the odd time (first start/cold start) maybe once every month or 2.

    Recently when it dose start i get 3 beeps but no warning light or spanner on the dash. I had it plugged into a snap-on scanner and no issues came up bar erratic oil pressure when revved [though oil pressure would change anyway when revving]

    There is also a knocking noise at idle sometimes but even a 2-300rpm increase and it disappears.

    It's been said to me this could mean the bottom end is shot.
    The car gets an oil/filter change every 10K/year and had the turbo replaced a few years ago at 190K miles its now at 240K miles
    The timing belt/water pump was done Oct 2013 aswell

    Is there anyway to know for sure its the bottom end bar just wateing for it to go ? the cars only worth 2K id say with its millage

    Get the car diagnosed and stop driving it in the meantime. Bottom end bearings do go on these, especially if it's a bxe engine. Usually it's a conrod through the block scenario so you may be lucky in that regard (if it is the bottom end that's causing the issues on your car), in that you won't need a whole new engine.

    Your engine will still have to be taken apart though and the conrod sent off to an engineering shop to be repaired.

    I didn't think the bxe engine was out till 2006 I could well be wrong though.

    BXE = Passat
    BKC = Octy/Golf

    Or so I thought...?

    You could well be right, I'm not sure myself tbh. I'd still get it diagnosed before driving it. Not so sure that other variants of this engine are immune from these bottom end problems.

    The golf, passat and octavia had the bxe engine. My golf has it. Basically all vag 1.9tdi cars between 2006-2008 ish although I don't know the exact times. I'm fairly sure the 1.9tdi octavia 2005 my dad had was bkc and not bxe.

    I know of an 06 Passat with a bkc. It could well be an 05 model though.

    There was probably no definite transfer date but to me it seems mid 2006 when bxe was up and running in most vag stuff before that was the bkc. But thats just from seeing various cars and years and which code they had maybe the bxe was fitted to some in 2005 I don't know. Although a quick check of the spare wheel well or the sticker on the door pulled seen when the door is open will tell the op which it is.

    It's on the timing belt cover too, provide it's the original cover that is.

    It's a BKC I checked the TB cover.
    Iv also been told it could be the flywheel.

    It's been scanned with the snap-on tool and nowt showed up bar erratic oil pressure when reved

    It's unlikely to be a bottom end issue. Flywheel would be a prime suspect. Could also be a worn out cam lobe and a damaged hydraulic lifter. It's common enough on those engines when the mileage gets high. You should get it checked out sooner rather than later.

    If it was a worn cam lobe wouldn't the noise be there constantly at idle rather than coming and going?

    Not necessarily, particularly in the early stages. They can behave very strangely when they wear out a lifter.

    Still more likely to be a flywheel issue though.

    Thanks George,how would i know what was the issue as the mechanics both said bottom end due to the noise and oil pressure ?
    The cars not worth alot so don't want to end up throwing €€€€€ into it as i was hoping to change for an 07-09 A4/A6/Superb next year

    Get another opinion. Where are you located?

    In any case it is likely to be an expensive fix. If it is a flywheel problem or a camshaft issue then you are looking at €800 plus. Bottom end problems will most likely cost more again.

    Don't know if it applies to Ockies but the BMW 2.0 litre diesel uses a rubber mounted crankshaft pulley that when worn gives exactly the same symptoms, in fact when it happened to me the AA insisted on recovering the car because they thought it was oil pressure related and the mechanic dropped the sump to check the oil pickup was clear before finding the crankshaft pulley fault
