Yes my Skoda can be more fuel efficient at a higher, but still legal, road speed than when on sections with lower limits. The car must be geared to be more efficient at what the constructor thought would be normal cruising speed. When the limits here were reduced to 80 it was a real pain! Car will cope with 80 in 5th but with all the hills around here it was regularly necessary to drop to 4th and fuel consumption went up! Must add that the restriction wasn't a fuel saving measure but aimed at reducing accidents & injuries.

The best time to do a brake test is when the roads ARE busy. You stamp on the brakes and the cars behind all benefit and get to test theirs as well. You are performing a public service. 🙄

I've got one of this type, bought it when I needed to change the filter the first time after I bought the car. Since then it is me that fits the filter so don't over do it so I can remove it without a tool.

Right then, 1. nothing untoward, other than a bit of a mess that could do with a tidy up. 2. Before trying a filament bulb I got the engine running and the oil pressure up to the light going off. Blipping the accelerator didn't get the led to flicker. So went to make a test wire and bulb, which will always come in handy. On return started car and this time gave it some real heavy foot, it did flicker. Fitted a filament bulb that was tested to be 100% sure it worked. No flicker! (I can hear Mr Lewis laughing 'I told you so'). Refitted led flickering returned. 3. Used the test wire which was fitted with a led connected to battery and all the wire and bulb placed on top of the coil. Yes I did make sure it was connected the right way round and not 'back to front' Ran engine and reached across to the carb to give it some welly. No flicker! Fitted filament bulb and went for a run 'round the block', all as it should be as far as I could see. For the time being I'll stick with the normal bulb even though I would like something brighter. When I get bored and have nothing else to do (what really?) I might make up a replacement wire with a led and run it well away from the coil, ht cables etc to see what happens. Thanks to all for your thoughts and suggestions I would have liked to have been able to find a 100% sure reason for the effect.

Interesting. When I tried 2 leds with different power consumption I did get the flicker, although the lower rated bulb was less visible, as would be expected. Lunch break nearly over so I'll soon be able to go and have another look. I'll report back at tea break time. Oh, yes been here nearly 30 years and still have a tea break in the afternoon, some habits can't/shouldn't be broken.

Well, I'm aged between 21 and 76 so I will have that coffee then go for a drive in the sun and on return fix it ( I hope) or ignore it.

That is where I am as well, I like to know 'why' in general and hopefully understand. If all goes to plan I should have the time later this afternoon to have another look at it in 3 steps. 1. Careful inspection under the dashboard for any faulty wires. 2. Fit a filament bulb in place of the LED. 3. Make a test lead with a bulb and run it a live feed (probably the battery) via the bulb ( if I can find my old soldering iron & solder in my 'archives' to the sensor. I will of course report back. Watch this space. Thanks to all for the help & suggestions A bientôt

How close is 'pretty close'? The loom goes along the side valance to the bulkhead and does get quite close to the coil. As well as trying a good old filament bulb I think will also try a temporary wire going 'the long' way from the bulb to the sensor thus keeping well away from coil, distributor & HT leads. Isn't life just full of fun, at least I'm certain (🤞) there isn't a genuine oil pressure issue and can simply regard the problem as an exercise in practical electrics. 🙄 Thank to all the professors who are enlightening (💡) me. Ah, 18h30 - apéro time!

Yes. All instrument and warning bulbs are LED except the red ign. light, and have been for quite some time. The LED for the oil pressure warning was changed a few weeks ago for a brighter one. When I swapped the bulb for another the other day it too was a LED but the less bright version. Maybe I should do a bulb swap and put in a filament version and see if there is a change. The short could have been there for ages but I never spotted it with the less powerful LED. You have to bear in mind the car is a convertible and is driven with the roof down all the time hence the reason for wanting bright warning lights to be visible in the sunny conditions Normandy is famous for.😎 I'll do a bulb swap tomorrow if I can get time free for the car. I have ordered some wire, correct colours, and a few other bits and pieces to make the postage worthwhile Is it, my wife is bi-polar. One day with the penguins, the next with the polar bears.

So very, very true

And some string to tie it to your head! I nearly lost a baseball cap last year, happily it landed on the back seat. The new one I treated myself to has been modified by Mrs. and has a draw string from an old bag ( no comments please) that goes under my chin. Very discreet - I don't wear the cap when not in the car. As for Panama hats : Mrs bought me a genuine one when she was in Ecuador some years ago. Handmade by Homero Ortega P & Hijos.

At that point it was still connected. I did think of stopping and disconnecting it but knowing my luck a neighbour would have driven past just as the bonnet was up, the reputation of British engineering would have been lost forever! As I have mentioned the fault is there even when the pressure switch is disconnected. It is erratic, after 'fiddling' under the dash it seemed to have been cured but within a couple of hundred metres it was back again. I'm going to have a VERY close inspection of the mess of wires under the dash next. As we all know to do that is "less than easy" and my back has to be having a good day or else I risk being stuck . .Picking strawberries & raspberries in the garden for over 2hours this pm did me in. It will NOT win, a draw is possible though 😠

I wasn't confident either but worth a try, after all no cost involved 🙄

Did wonder about the bulb being the cause :

It should sell very easily I would have thought.

Ok, as you asked. Checked the visible loom and wire under the bonnet all looks fine, although the wire from where it comes out of the loom and goes to the sensor is a bit (lot?) crusty and the insulation is broken in places but well away from anything. To be honest I was aware of this and it had crossed my mind (quickly) to do something about it. Under the dash, apart from it being messy, again no obvious fault. I did wonder if the bulb holder was shorting onto the back of the instrument unit, so pulled bulb holder out and let it hang free - still did the same. Put it back in and it appeared to be ok. Went for a run on the local bumpy lanes, fault did reappear. Still faint and intermittent, seems to get brighter/more frequent as the revs/speed rise - up to a point over 50mph it seems to stop. On the way back home I even wondered if the bulb itself could be the cause - swapped bulb still there. I am going to give the under dash area another check but I will order some new cable in the same colour combination (white + brown trace). As the postage is a bit more than the cost of wire I'm going to check my stock of connectors etc to see if there is anything else I need. I would prefer to be able to find the real cause in case it results in other problems. In the meantime I will use the car as it is clearly electrical not lubrication. And now for something completely different : I have to go and pick strawberries and raspberries in the garden, that's the afternoon taken care of.

Got one! Somewhere in the bottom of my 'tools I never use' box. Solder? I think there might be a bit there as well. My first check will be to follow the route of the wire ( especially behind the dashboard in the mess there!) and loom to look for any obvious damage causing the short circuit. If the loom/wire is rubbing on something it could cause more trouble in the future so better to be safe than sorry. Second step, make a completely new length of wire from the bulb holder to pressure sensor as I'm convinced it is along this section that there is a problem.

Yes, but although I have spare bulbs no bulb holders 😒

Effectively that, the diagram shows it on the input side of the stabiliser so yes 12v from ignition. That's the same conclusion I have come to. I need to look at how I can link it in easily. The wire is soldered direct to the bulb holder which means I'll have to cut it and fit connectors. Although I have test cables I don't think I have a length of suitable cable in stock for a permanent replacement, visit to motor factor called for this week.

No mix up with bulbs, they haven't been touched in ages. I'm convinced it is nothing to do with the engine lubrication, my wallet gave a big sigh of relief!

And/or : to keep the sun off their neck. 😁

Just had a look at those posts, thanks. Oil would be due for a change this summer so I guess having to empty it isn't a waste. Tricky part is a drill bit 9/16", unless the closest metric will do 😁 Exactly, I still think the most likely suspect is a fault in the wiring somewhere letting it earth. I should be able to have a closer inspection in the next couple of days

Just looked at the parts diagram. Did you replace the whole assembly or just the spring?

OK, another possibility to look at after the wiring.
