VW Golf 1.8 2005 - Oil warning fault - Unresolved #

Year of Manufacture *: 2005
Engine Size and Code *: 1800
( Optional ) Scanner Used: KTS

Hi guys

I don't know if this post is in the correct forum but here goes the vehicle has done 88,000 and it came in with the oil warning light and display flashing on intermittently normally after a motorway run I have looked at the obvious /flushed oil replaced oil pick up and oil pressure switch but it still flashes on it can go 10 days and not happen I have tried to get my oil pressure gauge in to check the pressure but it is a nightmare it took forever to change the switch .the only fault code related to oil temp intermittent signal out of desperation I changed the level/temp sensor in the sump I would change the oil pump but its the one that's chain driven and is a big and costly job and I wouldn't be confident it would cure it .I know I should check the pressure but it never happens in the workshop any ideas

Thanks John

Hi John

If I remember correctly this same problem occurs if the bonnet switch is malfunctioning.

can you read MVB's? You could check pressures there and also check bonnet switch.

Check if reverse lights work, and fuses relating to them, had a golf plus doing the same and was reverse light switch on box.

Measured value blocks. You would go to Onboard power supply or convienince unit and check the signals. Ross tech will tell you which ones but if not I can find out. Jim

Hi guys the vehicle is back in I am not sure what I am supposed to be measuring the bonnet switch looks ok and lights up the display in the dash to tell you its open the reverse lights work and there are no fuses blown .The oil pressure is 2 bar on tickover I am beginning to wonder whether it is the oil level warning that flashes up even though I have changed the sensor in the sump any ideas ??

Hi,John
If the wiring loom is routed close to starter motor,( similar to passat 3C ) might be worth checking for chaffing around starter area if not already checked.

Hi John
Can you scope the oil pressure switch on a long road test. It may flicker to earth not bringing the light on [ If you can catch it with light on even better]

If the light comes on and the scope doesn't go to earth you can be happy its not oil pressure.

Then switch disconnected, wire a fused bulb to the switch and scope again. If it flickers to earth you know the faults the oil pressure or new switch.

Hope that makes sense regards Ian.

Do you have codes in aircon?

Did an 05 golf with tdi BKC engine this week, was a/c pressure sensor short to ground.
Seems to be protected by same fuse, although there is no mention of it on fuseboard layout.
Until you check vivid that is!

Have you checked all of the fuses?

Liam.

Hi John I am going to throw my two penneth worth in, we have been plagued with VAG warning lights just of late and most have been traced back to the multi plug connections on the PCB of the dash board.

Just had my brother-in-law's Polo which spent a lot of time in Winchester getting nowhere running up large bills. The problem was intermittent coolant warning lamp which would randomly come on, also the key would not be recognised occasionally and would not start. The immobilizer light would also randomly light up when driving. No codes for the coolant light but the key would come up with aerial recognition & incorrect key codes. After studying the wiring diagrams we traced the relevant pin no's in dash & under a good magnifying glass you could just see slightly cracked solder joints, with a fine solder gun we sucked dry & re-soldered the joints and wala no more annoying beeps or lights flashing. We had a similar job not so long ago we solved another warning light but couldn’t solve the immobilizer but after installing a second-hand dash and this also cured the problem. Worth a look!
John Kennard.

I have had this fault before.
After reading advise from this forum i checked the wiring going to the bonnet latch switch(I may have removed the latch to do this)and found it to be shorting out or broken(it was a couple of years ago) very close to the latch.

Hi John and Colin thankyou for your inputs my customer spoke to me today to report that since we serviced it the light has not come on I dont think this has cured it and agree with you both that it is an intermittent electrical fault he is going to carry on driving it untill the fault becomes more frequent I hate intermittent faults I will keep every one posted many thanks to all .

Thanks for all the input but I never got to the bottom of this the last thing I did was to change the oil and filter and add a Forte additive for worn engines the customer reported that the light had not been back on fingers crossed sorry I have not posted a responce sooner I have half expected it to show up again having posted this it probably will cheers
