Golf MkV Oil level light out and crank sensor?
Discussion
Hi all,
Been stalking the forums for some time now, and after asking a similar question on a different forum - which will go unnamed - I decided to join the Pistonheads community in the hopes I got a more appropriate answer (that extends beyond 'don't buy a TSI golf...)
1. My main concern right now is that the oil level light (orange, not red) on my dash isn't coming on during start-up. It came on a few weeks ago, so I checked the oil and topped it up. The light stayed on for a few days and then went off. I thought great, but then realised the light wasn't showing up during the start-up. Has anyone got any ideas what that could be? I'm thinking the original issue with the light not going out was the switch in the bonnet catch area but the light no longer working baffles me completely.
2. Secondly, real quick, my car seems to be running through oil very quickly. Any one know of a rough volume of oil I can expect to put into the car every X number of miles? There doesn't appear to be any leaks.
3.So that's issue one. The second problem I have is that the car takes a while to start (not even necessarily from cold). It will start, it has never not started but some times it will take a while to start. I brought it into the garage and he said it might be the crank sensor. He also said it's a repair job that can be put on hold for a while because the car will use other means to get the timing of the engine right. I do trust him but it's something I thought I'd ask anyways as I want to get it fixed. He said he reckons the sensor is behind the supercharger which means it will likely take the better part of 5 hours. Reading some VW literature on the TSI engine design and it said that if the crank sensor goes, the car wouldn't run at all anymore, which makes me question what is causing it. Any ideas?
Thanks for all the help!

I've had 2 cars with 1.4Tsi engines. 2012 and 2018 versions. The 2012 used very little oil. Not more than 500ml per 10k miles. Maybe less I can't recall exactly. The low consumption continued up to 60k miles when I traded it. 2. Secondly, real quick, my car seems to be running through oil very quickly.

My 2018 1.4Tsi 150 has had 2 or 300ml in 9k miles.

Thanks for the info. I'll need to keep a closer look at it. I'm going to get it up on the ramps this weekend and see if there's anything going on. No leaks that I've come across so far though!My 2018 1.4Tsi 150 has had 2 or 300ml in 9k miles.

With respect to the oil usage, check the PCV valve. Our 2.0 TFSI was using quite a lot of oil and it turned out to be a split diaphragm. £25 and half an hour of fiddling later and it now uses no significant oil.
hanks! How would I check that though? kambites said:
Well ours made a significant whistling noise at idle with the bonnet open but I don't know if they all do that when they fail. It wasn't loud enough to hear with the bonnet down but was fairly obvious with it open.
I'll check that later tonight (bonnet catch is broke which means I have to do it manually, it was going very well but last two weeks stuff has just been breaking and I can't find out why)haggishunter said:
Check the plugs, if it’s burning oil the plugs will foul up and it won’t be keen to start. They have a tendency to knacker coils too which won’t help either.
I put iridium ones in it when I bought it so I hope they're not fouling up! It's never not started. and it doesn't chug or anything. It just takes a couple of seconds longer than I'd like or expect.GolferTSI said:

What year golf TSI is this?
2007. What year golf TSI is this?

This. Without data, the parts cannon will end up being deployed, which gets expensive.For example, sluggish starting can be caused by many things. Weak fuel pump(s), stretched chain, fouled spark plugs, weak coils, weak battery, dead crank sensor, bad MAF sensor etc etc.
Without a live data scanner it's pure guesswork, but I can tell you if you currently have a full rpm range, the crank sensor is fine. So that's £150 + labour saved.
