Vauxhall Owners Club

Either a plug to the lamp has become detached or even a rear suspension suspension level sensor rod has become detached

Two things I can think of - 1. if the belt has previously come off then was the tensioner okay or is it worn and therefore throwing the belt off? 2. a split turbo pressure hose to intercooler can produce this sound

Wow! this is a strange one - and you seemed to have done all the checks to verify the individual systems Are there any other fault codes (battery charge, ABS, Traction, etc)?

Hi....and welcome to the club I would start my search on eBay and make sure you check Opel even if you have to get it shipped in from Europe

I believe i have seen something on eBay to resolve this - worth doing a search

Did a google search for images of vacuum hoses so maybe if you zoom into some of the images you may find the locations https://www.google.com/search?sca_esv=79f64c1ff2a1fa8b&udm=2&fbs=AIIjpHxU7SXXniUZfeShr2fp4giZ1Y6MJ25_tmWITc7uy4KIeioyp3OhN11EY0n5qfq-zEMZldv_eRjZ2XLYc5GnVnME7glWodDcaQwvGYJtospyF4GO5MC0p7Um53mJ2FnRmWwYsd7hv9AfrxH9qUZHRFRalIEFxklAeOUUu2HryaeymXfIRKrbIDV05r5-M57YhEO4LvvmDEUH_Q8-RZZ_9JlQJwsEpg&q=1999+vauxhall+cavalier+1.8+8v+single+point+injection+vacuum+hose+location&sa=X&ved=2ahUKEwjIjuSelauQAxXBbEEAHQ6NAV8QtKgLegQIFRAB&biw=1659&bih=847&dpr=1

I have used a company that is based in Europe and great service - AutoDoc, worth going onto their website to see if available

Its worth pursuing with treatments on a regular basis as some seem to work really well. Wynns is a good make and there are others available that I would trust (STP, Redex, etc) which may be worth trying to see if any difference

That's great to see some of the old cars still around - i used to work on these when they first came out and never remember getting annoyed by anything unlike the Leyland cars I also used to work on. Happy to offer advice on the Datsun/Nissan when you get round to reviving it in the future

Glad to hear you had a (semi) successful outcome - the radio does not consume huge amounts of power but left on over time it will flatten the battery.

Yep, sounds like the level sensor as the adblue chrystalises over time and this usually affects the system Please let us know how you get on with it

Sounds like the level sensor is sticking which happens when the adblue chrystalises over time. It would need flushing out and refilling at the least otherwise it could also be the sensor that needs replacing as well.

There are radio code sources online, best bet is to google search it and see what comes up. Some of them you would have to pay a nominal amount to get the code but others are free. You will however, need the serial number from the radio to provide them with something to search against

I can't see the sensor as such but the position is bang on so maybe it is. Worth putting the scanner on the car and see what the live readings are for the ambient air temperature sensor - you'll soon see if it is out of range

Oh didn't realise you had an old Datsun, Andy - what model is it?
