Title: Few questions regarding some parts
Post by: CM690 on 09 June 2011, 19:27: Over the weekend I'm planning on replacing a few parts on my Golf 1.4 'L'.

I changed the oil pump and one of the pressure sensors around 2-3weeks ago and although my oil light does come on its not as much as before (virtually all the time) now it only comes on under around 1,500-2,000rpm so I'm guessing its the 'other' pressure sensor that I need to change as I only changed the one. :undecided:

Here is a picture of my engine with the sensor highlighted in red. Does anyone know where any other oil pressure sensors are on my car?

And which one I need to buy, here is a list from GSF Car Parts.

Secondly, I changed my headlights to Mk4 style lights a while back and have noticed people flashing me. I've worked it out that one of my bulbs is flashing! When I stood in front of the car the other day I noticed it flickering, is this a sign of a dead bulb?

Do you know where I could pick one of these up? What bulb is this? Front Fog? :/ I dunno

Is this the bulb? :tongue:

Any help is greatly appreciated. This forum has helped me so much since I've owned my Golf! :D

Post by: Leon27 on 09 June 2011, 19:59: That bulb looks to be the sidelight bulb but fitted with an LED bulb as opposed to the traditional W5W ones:

http://shop.ebay.co.uk/i.html?_from=R40&_trksid=m570&_nkw=W5W+led

It also looks like there should be LEDs lit around the centre one?

With regards to the oil pressure - I had nightmares getting the correct oil pressure switch for mk Mk2 16v as GSF kept on supplying me with the wrong rated ones. Confirm a like for like sensor by removing the old one and reading off near the threaded section the range of pressure that particular sensor covers.

Just to be sure though, did you have to use the same pick up and clean it out or were you supplied with a new one? You may need to get an oil pressure guage on the car to confirm that its ok then possible try a new sensor. Cant confirm where the other sensor is though but hope the rest helps.

Thanks I'll take a look at some of those bulbs, they seem cheap enough. Yeah when the bulb flickers the LED's around the center one are the ones that are flickering.

I'm guessing the one I already did was the right sensor because its solved my light come on after 2,000rpm but I just needed to know where any other pressure sensors might be. Unless that's the only one :( Not sure.

I used the new pick up that was supplied with the new pump. I was thinking about a gauge but I thought the best place to start was the sensors just in case as they are pennys :D

Post by: dom on 09 June 2011, 20:57: The side light bulb should be a 501 i'd have thought :undecided:
Title: Re: Few questions regarding some parts
Post by: boneybradley on 09 June 2011, 21:29: all vw's I have worked on had 2 oil pressure switches (1 for idle and the other for 2000+) although i can't help with location

and the bulb will be an led 501 type (try ebay)
Title: Re: Few questions regarding some parts
Post by: CM690 on 09 June 2011, 21:44: :( No one seems to know the locations, Ever Google isn't helping :O

Yeah I've found some on ebay going pretty cheap thanks guys!

Post by: trog_nfs on 09 June 2011, 21:51: If its anything like an ABD, then the AEX's should be on the head. Doesn't have an oil cooler or anything, so there can't be any more places it could be.

EDIT:

Heres the pic from wagenstad
(http://www.wagenstad.com/diagrams/go-1996/9-919-60.gif)

Its the top left, number 2.

Says its a white one, and looks like it might be on the front left of the block

By on the head, do you mean near the one I've already changed? Somewhere up there? Do you know roughly where abouts in relation to the one in the image or is it in a completely different place :tongue:

Post by: trog_nfs on 09 June 2011, 21:57: On my old ABD, it was literally the other end of the head.

But the wagenstad pic makes it look like its on the block.

I'll take a look at both places, could you link me to the page showing the picture you linked with the numbers to each part. Cheers

Post by: CM690 on 12 June 2011, 07:47: Ok so I took my car to my dad yesterday and we spent a good few hours trying to locate this other sensor. Going by the image you posted above of your engine to start with we couldn't find it at all. So we used the Volkswagen diagram and looked at the two places it was suggesting and it wasn't there! :shocked:

My oil filter screws directing into the block so it wasn't there and it wasn't at the side of the engine like under the timing belt area like it was directing in the picture.

I honestly have no idea.

All I did was replace the blue one with a black one I also got from GSF to see if that made a difference and it is now slightly worse so I've got to change that back to the blue one.

On another note, I did change my air filter for what looks like the first time in it's life (the filter was literally black xD) and now my car seems to have more acceleration...although that could just be me thinking it has :tongue:

regarding the sensor though, no idea what to try anymore

Hi,sorry to butt in but i have just read the problems you were having with the 1.8bar oil pressure location although it was a while ago. Im having exact same problem as you did. I have a Golf mk3 1.4 multipoint AEX engine code. What i noticed on trogs pic of the back of the engine is its slightly different. I think its an AEX single point injection in the pic and mine and yours are the multipoint AEX engines. I may be wrong though. Say,did you eventually find the location for the 1.8bar oil pressure switch. Just brought my car back from an independent vw garage to find the location and they were baffled. They looked at the side of the timing belt covers as in the diagram but found nothing. Its listed as having two oil pressure sensors even at VW stealerships. Personally i dont think its got one. I just changed the one on the left of the head on mine and it made no diff. Oil light/buzzer driving me insane.

Post by: gasketface on 09 July 2012, 21:17: OP.With you aying that the oil light was on nearly all the time and that a new sensor makes it worse or has little difference i would be doing an oil pressure check first.It sounds to me as id your engine may be worn out so that you have low pressure.If your air filter was filthy it says to me that the car was'nt serviced properly which may also mean cheap oil was used with few changes.

It could also come down to a worn out/faulty oil pump but my guess would be a blocked pick-up pipe/strainer which is common on high mileage old cars.

Good luck,hope you get it sorted.
