I've replaced the oil filter and the high/low switches myself (see above in thread) a week or so before taking it in but it didn't help, however I definitely noticed a change in behaviour of when the errors appear, it would show up 9/10 times when applying heavy throttle, now it's about 3/10 times - not sure what that could indicate though. I've been under and throughly looked within the engine bay and can't spot any leaks, although it's very possible I've missed something. Another garage (which I'll be taking it to once I collect mine tomorrow) suggested dropping the sump and checking the pickup pipe etc, also mentioned the oil pump itself. Will have to ask tomorrow and see what they've actually done to fault find and so on.

Yeah, going to collect it tomorrow and will take it to another garage. I did ask over the phone, but she said where it's not a "mechanical fault" it can't be fixed, and not much else. They're very reputable in the South East for VW group cars, so I'd like to believe they've got it bang on, but with an explanation as broad as that, it does leave me wondering.

Hi @Breezy_Pete @TheClient Garage got back to me with the diagnosis this afternoon, it's a genuine oil pressure issue, the lady mentioned that my car operates at 0.4 bar (when idling, I'd imagine), which is below what it should be. They've said it's basically irreparable and requires a new engine, and have quoted me £8800, not including labour. Devastated isn't even the word, I just can't understand how it can just be faulty with no fix other than to replace the entire engine, but hey ho. Thanks for all your help.

The ONLY thing I haven't done, is replace both switches with OEM parts. I may just order the same ones @Breezy_Pete listed earlier on in the thread. For the sake of £30, atleast I know both parts are genuine OEM, and if it doesn't fix it I can say I tried.

I've already replaced both blue and brown, but to no avail. Although the parts aren't OEM, but no reason why they shouldn't work. I've purchased a new oil filter today so will fit tomorrow. I did do some research on the N428 but I'm not sure if I have the ability to replace that myself, and the part is quite expensive (around £100) so not sure if I'd be comfortable doing it to be honest.

Funny you say that, contacted another VAG specialist and they said either the oil pump or oil relief valve.

@Breezy_Pete @TheClient Update: Replaced the brown switch - the oil light now comes on a lot less often but still happens once or twice. Goes into EPC mode more frequently now - 9/10 times over 4k revs, scanned it and it came back with the blue switch malfunctioning too - replaced the blue switch but no difference. At a dead end so have booked it in with a VAG specialist at the end of the month. Have a feeling it's going to be expensive.

Hi all, I've ordered a rear diffuser which has come unpainted. Has anyone here painted or sprayed their front/rear diffuser? Did it come out okay? or is it worth just paying a professional to do. Thanks

The replacement should be here tomorrow, so will try that straight away. Failing that, cleaning it. Failing that, £££ Fingers crossed

Yep, strange isn't it? Wondering if it's a dirty connection or something, have some brake cleaner in the garage so tomorrow will attempt to clean it. Will keep you posted.

That time correlates with when the Oil Light came on yesterday afternoon while I was driving. And yes I've never seen that before but I did change some settings within Carista so I presume it's to do with that. Actually thinking now, it could be my auto start-stop, I've turned it off via Carista. Have tried clearing codes, short to ground disappeared but the exact same sensor one came back once the engine was running.

Have just done this, see attached. After looking at the code, every post says a sensor fixed the issue for them.

Those codes for green/blue are the correct ones installed, the brown is not. It shares the same part number - but not the same bar range. Will have to order and try that. Thank you Yeah IIRC it was 2 pin, and it did fit.

Have sent it across, thank you

Shall I DM you? Will give it a go, thanks.

This is the one I think I need https://www.lllparts.co.uk/product/038919081K/oil-pressure-switch This one is the one installed currently https://www.darksidedevelopments.co.uk/products/oil-pressure-switch-for-vag-tfsi-petrol-engines-0-3-0-6-bar.html It's weird because that second one covers loads of part numbers (including the one I need) but it's a different spec.

Both the 0.3-0.6 installed and 0.55-0.85 I need, are brown

I saw another thread where you used LLLParts, so I just piggybacked off that to find the part # I needed! Thanks anyway

Weird, okay. Since the other two have been replaced, that's the only switch now running the 'incorrect' bar rating. I'll try that as one last 'cheap' fix. If not, to the garage it goes. Really appreciate your input.

Following this, asked the guy that replaced it what part he used, he's used a 0.3-0.6 bar switch when it's meant to be 0.55-0.85 bar. This'll be the issue I imagine.

Replaced the third sensor - no luck! Still shows the light when moving at low speeds/idle but goes away as soon as I get 8+ mph. The brown switch already been replaced but it's not an OEM switch. I may try removing it today and scanning as you suggested. Thanks!

Interesting stuff. Thanks for that. Will try replacing it anyway and see if it changes anything!

After being under the car and trying to find it, and with the help of @Breezy_Pete on Wednesday, can confirm the 3rd switch is here. Thanks for further clarification @TheClient! Will be replacing it Saturday morning

Hi all, looking to get a DTUK PedalBox for my Octy - but want to buy secondhand, does anyone know what the 'pedal number' (it's a 4 digit number) is for a 2014 Octy VRS Estate - or where I can find it? Have looked on LLLParts for it but can't find it! Thanks

Lifesaver, I am having that exact same issue so hopefully that's it. Will attempt to replace it and see how I get on.
