Hi there, I have a scirocco 2.0 tsi petrol. I have also owned a 350 not long ago. Mine is pretty good, it's pretty reliable, nothing has gone wrong with it since I've had it. I chose to get a petrol as you can get 40mpg on a good run, it's quite a light car. I thought about the diesel but the dpf put me off and there's not that much of a fuel saving between the two. I've heard the 1.4 petrol has issues though. Handling is good, the cabin is nice and we'll put together, it's comfortable inside with adjustable suspension too. If you like the looks of it, it's a good buy.

Hi. Just a quick update. I got it back from the garage today. (chose not to fit new pump as was sceptical) Started it up and it was fine. Psi about 50. Then drove it for about two mins around the block and it fluctuated, dropping down again to 5psi I Topped up with about 500ml of oil and started it up and the psi stopped fluctuating. It read fine. Only dropping low when turning around corners. It runs spot on and the pressure seems fine. It's just the going around corners which is the issue. I will keep an eye on it and will take it to Horsham Dev. Soon.

Yeah, that's a possibility. But yeah I agree, I'm sure there are many on here yourself included, that have surpassed 40k on the original pump. I found another link which stated that the DE oil pump couldn't handle the increase in rpm that the revup oil pump could. But again, there's probably people on here that have had remaps and their original DE pumps are still ok. I will have a look at other possible issues today and will update any info. Cheers.

-G- I have spoken to the garage and it is apparently the internal component of the oil pump which has failed. So the link I gave would supposedly be the problem? A Nissan one apparently lasts "only 40k". So the question is, surely just replace the oil pump.? Has anyone here even had to do this? How much should this be? I should be getting the car back today or tomorrow. Thanks.

Ok thanks. I'll have a look when I get it back tomorrow.

Hi, that is a possibility. And yeah it's hard, But he told me that he put in 4.7 litres, which as we know is the correct amount. Even if he didn't even change any, i had done the previous change two weeks earlier (and the level was spot on then, so it'd be full either way. I bought it with an aftermarket oil catch can. I'm not sure if this could cause any probs..?

Ok.. I started the car previous day it was fine psi 55-65, but seemed to have lower power, and normally when driving it was always about 55psi Or thereabouts. I noticed on my way home the next day that the psi was at 15psi when driving. This got my attention, so I carried on looking at it, then noticed it down to 5-10. Then at junctions in neutral it went down to about 2psi. When I was driving, in higher revs it went up to 5. I was about a mile from home and noticed it at under 5 so I parked up on the side of the road. Literally As I parked up the oil light came on and it was on 0. Engine off. The oil change was about two weeks earlier. So I presume it'd be full. I think I'll do that. Thanks. There's no noises and we're none when I was driving. I've decided with your advice and other opinions that this whole "weak gear" thing is a bit dubious. And further more simpler tests need to be explored.

5w40 62k 5w40 at 72k then another one year later. 10/60 race oil at 78k 10w40 year later The earlier and later oil changes don't say what weight. But it was done. It's on 131k. The garage have put in 5w30. I stand corrected, i don't think it's had 5w30 before.

Ok. I looked at the service history and it starts off its life with 10w40 semi then halfway through goes to 5w30 with one receipt near the end stating 5w40. So it's a mix. When I got it, it was quite low on oil. Since doing changes, I've had issues.. Though I've used the correct grade. Though the garage used 5w30, it was acea c3. Which I queried. Would that cause low pressure?

Yeah that's possible. I know that sort of thing happens. When I first got the car I did a change and put in 5w40, but got a misfire few days after. After the garage did the service and another change (due to them thinking 5w40 was too thick and the reason for misfire, it was prob the plugs) the misfire cleared but then got low oil pressure. I think what I'll do is get it back, check oil over, get a specialist opinion/quote and go from there.

Thanks mate, Yeah, I've decided to speak to them. Hopefully Monday. I cant afford to fix it and then it turns out that that wasnt the problem. If its too expensive I may be forced to sell it as it is. Obviously being upfront about the issue and cut my losses. Not sure if itd get any interest. It has loads of receipts and is vgc. I'd love to fix it obviously, but its become too much so far. I hope it wont be too much.

yeah I havent driven it hard. It has had a new clutch, so I rarely took it above 4k whilst it was bedding in. He quoted labour at 9 hours. I'm trying to google as much as poss. it seems like a very rare diag. Ive emailed horsham and abbey for their advice. It sounds like it could be a few things. I was told that the pump was ok. The car hasnt been turned over for obvious reasons, I will need to ask a few questions on Monday. Cheers.

Ok, the thing is the oil was changed only two weeks previously and I have only done about 300 miles. I know having a low oil level can lead to low pressure but It shouldnt be that due to the recent oil change. I typed in 'oil gear softer metal 350z' to google and the first result with the title 'INFO' from the my350z website has some info, maybe this could be the issue? I think I'll take advice here and speak to a specialist. Thank you.

Hi, It has had a service, so oil would therefore be ok. 4.7 litres was put in. So it shouldn't be low oil. I was told that the timing chain needs to come off to fit this part, hence why I'd need the timing chain kit. Im looking at 700 to fit in total, but I basically need to know if anyone has heard of this problem with this 'degrading/softer metal part'. Thank you, appreciate any input.

Hi, I'm using a local garage, he's worked on my cars for a while and has been helpful so I just decided to take it there. He used the term 'cog' when describing the problem and it being a softer metal. Could it maybe be another part that suffers this issue? I've never heard of this issue and as I'm new to zeds it's an issue I need to research a lot. I am reluctant to buy the kit for £200 as this would undoubtedly be a non Nissan part at that price. As you say, it should be more expensive. And I dont want to fit such a vital part if the manufacturer/part isnt reliable I'm in Hampshire. You're right I do need additional opinions, I only had the diagnosis yesterday and came here first. Thank you.

Hi. I'm a new member and owner and this is my first post. So I'd just like to introduce myself. Firstly, I would just like to thank people here for their advice/experiences with their zeds as I have read a few posts regarding repairs/mods/diagnoses etc and its always valuable and helpful. I bought my zed in December, its an '05 gt spec and had a discounted price as it needed a new clutch and f/wheel which I had fitted. However a bit later it then developed a random misfire which I had repaired. (Turned out my spark plugs were dirty) and had a mini service and at this point it was running great. I'd like to ask a quick question to members as I now have an additional problem... Mine suffered very low oil pressure recently 0-5 psi whilst driving and I immediately pulled over, turned off engine and had it trailered to my local garage. I have been told that the oil pressure sensor/oil pump is ok. But that the earlier 350z models before '06 had an 'oil pump cog' made of a weaker/softer metal that wasnt present on later models. This cog supposedly degrades more easily and now I need a timing chain and oil pump kit and to fit which has the harder metal cog. It it would be 9 hours labour to fit, the kit being £200. Has anyone here heard of this softer metal cog issue? If you could help, I'd appreciate it as I've been a little unlucky so far. It's a great car and I'd like to see it working. Many thanks!
