Clogged fuel filter. Veg Oil and Bio do a grand job of cleaning out your fuel tank and lines, which then all gets trapped in the filter - as it should. Change the filter and it should be fine. This time of year it won't be too high a concentration of oil (and I'm assuming we're talking 200 or 300 here?), the TDi's can run quite happily on 100% oil, I know, I have.
Won't account for the tapping though. I have the same on my 200. I don't worry about it,
I've got temp gauge (which is how I know what she's really running at and can speak from actual experience), oil pressure gauge and boost gauge - which as Nick rightly points out, I hardly ever look at! It does help though in that I've for some reason had a spate of hoses falling off, the gauge and turbo to FIP. No idea why, but it's made obvious by the lack of reading on the gauge. I have a rev counter also in a separate bin, not often I look at it though. Was installed when we were comparing various combinations of transmissions.
Have you fitted the Series sender unit to match the Series gauge? That said, I haven't, and my gauge isn't far off accurate. It never climbs above about 95C, which sits just about middle of the 'N'. Make sure the stat isn't stuck shut.
Yeah don't go with 3...not straight off anyway... Best bet is probably to go and talk to the manager, explain basically what you've just said, give him a chance to answer for his bill
I fitted Goodridge hoses to my 88 and 109 and I'm really not sure it was a good idea. Every time I do brake work now I end up having to re-bleed the whole system simply because I can't clamp off the corner I'm working on. Nor can I clamp off a corner to identify problems. I'm seriously thinking when the 88 gets her rebuild she'll go back to original rubber hoses
Yeah my 88's got loads of space, unmolested front panel, Series rad, no intercooler as yet though, that's a job for another day. The 109 has a Defender PAS box. Big mistake, and caused me no end of problems when the box needed replacing a few weeks ago, fighting for space with the radiator. Plus the expansion tank was getting in the way all the while
I wouldn't bother putting it on a galv chassis just to sell it. Lots of time and effort, not to mention money,, with the risk of it stretching out and out, or bit's getting lost.
I've got one, it was very good....manged to break it though...have got spares, but not got round to repairing it.
Makita do a battery one, friend just bought one, works for him, but whether it would be up to that much work I wouldn't like to say
