Buzzer of Doom - Novel Repair?

[brickinit]

We were in Northumberland this weekend on our pre Christmas trip and Basil had soldiered up the A1 without a problem other than the washers freezing up around Scotch Corner

He was parked up at my parents for a couple of days while Mrs B and I did the family visiting in my dad's Audi and I reversed him up a moderate hill to load him up for the return trip, via Whitley Bay, on Sunday but within about half a mile of setting off the BoD and flashing light came on!

This has happened in the past but it during the "test run" following an oil / filter change and I cut the engine, coasted to a halt, did some visual checks and when I re started it had gone off and has been so for about 2,000 miles except for one little winge when we were climbing a steep hill and got as bit bogged down in the wrong gear

Having read many of the threads regarding this I was fairly confident we had oil pressure but switched off and coasted for a while to see if this would work again but, sadly, was out of luck this time and the several following tries too so, being a highly trained ex RAF Technician, I used my years of training and skill to deduce a wack on the top of the instrument pod might be the way forward - and it worked!!

Drove the 200+ miles back, with a stop for petrol then fish and chips in Cullercoats, without another peep and have just been around the block in Basil tonight to check things out and all is well!

Guessing this may be pointing towards the "dry joint" in the circuit board but just wondered if anyone has experienced the same fault / cure

PS The Northumbrian coast has to be worth a visit in anyones books!

Don't tell them about Northumberland... They'll all bloody turn up!

B*gg*r, never thought of that Laurie - first one to venture into the sea may put up a post that'll put a few off!(once they've recovered the power of movement of course)

I learned to swim in the sea around Druridge Bay / Cresswell and as a result can drive a bay with J tubes in the winter without a beanie hat!

yep, ours does that , i gives it a knock every 6 months or so, been going on for years.

Of course, that jolt could equally disturb a 'good' connection required to tell you the pressure is low, Jaylo too

.. the clue being, that you would expect it to come on reversing 1/2 mile up a hill, ideal conditions, non

[brickinit]

Cheers for that HarryMann but I'm sticking with a half full glass for the moment! (must be the Christmas spirit as I'd normally be a bit "everyone's glass is half empty, it's my round, and they all want crisps" about it)

It was probably the wording in my post but we only reversed about 50 yards up hill then knocked the engine off while we loaded up. The BoD came on about half a mile up the road, which was perfectly flat, but isn't it funny the little tightening effect it has in your trousers wherever it happens!

Ah! I see.. a good quick fix then.

Here's a classic 'beginnings' of low oil pressure scenario... (2.1 DJ)

At least 15 minutes out from home; dual carriageway by-pass with roundabouts every mile or two; briskly up to 60 or ? between roundabouts; slowing for next one and waiting in top so can do a 5th or 4th to 2nd before entering; just on entering or hlaf way around - BUZZZZZZZZZZZZZZZZ

Easy then on exit, gentle till builds back up to 2000+ rpm, and buzzer goes off, might come back on between gears..

Oil hot, oil frothy (slightly overfilled maybe; endemic low oil pressure, probably a big-end starting to oval (if TD maybe turbo bearings/seals getting sloppy)...

Time to get a proper test-gauge rigged up, and check it hot (80C) and cold, below and above 2000 rpm

Buzzer has never worked on mine since I had it. Not even sure if it has one but from what i've read, having a working one causes more concern than none at all - backed up by a well known VW garage here in Cov who laughed when I mentioned it. Perhaps blissful ignorance is no bad thing.....
