    I've had lots of jobs done on the Bora, mostly sorted. I was told that after having the exhaust/cat replaced, it should have a bit more power.

    Marginally, perhaps, but I am conncerned about the lack of power. I have to change down all the time, even going up- a slight slope. It really feels like the clutch is slipping, but I can't hear it or smell it, so I don't think it's that.

    I've never had a diesel car before, but I would have thought a 1900cc diesel would be more powerful than my 1.6 21 year old Driver, but it's not. It's done 145k but doesn't seem to burn much oil. It's OK round town, but hopeless elsewhere.

    Is there anything else I should check out? Or is it really this pathetic? I know that it's really a Mk4 Golf and they were a bit sad, but is this all I can expect?

    Have you had it scanned for trouble codes?

    Most common thing on a mk4 for lack of power is air flow meter but they rarely show up as a fault, if you know somebody with vagcom they should be able to check the readings of it

    ^^ yep my vectra had a vac pipe that had gone brittle at the end and come off - was some sort of re-circulation thing for the turbo iirc and it was real sluggish. Popped it back on with bit of leccy tape and it was miles better.

    even if you have the 110bhp model, it should still put really well compared to a 1.6 mk2

    Thanks, Rob. I wouldn't even know where to look for a vacuum pipe. It looks so different from my Golf when I lift the bonnet that I take one look and put it down again!

    Problem resolved by Rob (Coalville Dub) at our meet, where he spotted the hole in the vacuum pipe, went to Halfords to get a new one, then came back to the meet and fitted it for me in the pub car park!

    He's now moved up to first place in my VW driver Top Ten :)

    Thanks, Rob - it's like driving a different car!

    yeah, those engines are pretty simple things really. mpg should improve big time too

    youd do yourself a favour by going over those hoses with a fine tooth comb to find any other grmlins

    when mine went I thought the turbo was goosed as it had such little power, was so chuffed when it was just a vac hose.

    Not so much when the turbo exploded 2 months later though

    Yes, what a surprise that was. Your Mum is one of about half a dozen - definitely no more - intelligent people at my ex-workplace. People with brains there are a rarity, believe me!

    lol at Matt :lol:

    does anyone have a diagram or checklist of the hoses that i can go through? iv got patchy performance - sometimes it just doesn't go.

    iv read somewhere else too that it may be vac hoses. anyone help me out?

    cheers!

    When you take the cover off, they're at the back, near the windscreen, if that helps. I'll take a photo of mine later on for you, though I expect they're in the Haynes Manual of Lies, if you have one.

    just take the cover off, and follow every hose that isn't big enough to be carrying water or air (boost pipes) and check the whole length of them. mine had knackered one's after 4 years old

    It's happening again, this loss of power [:^(]

    I've checked the vac hoses again and they all seem to be fine, but yesterday, going up the long hill to Ashby on teh A42, I had exactly the same pathetic power as before replacing the hose.

    So what else should I be checking? (I put some ASDA diesel in yesterday morning - could that be the problem?)
