Hi,
Was driving home from work the other day and some dude in a S3 started tailgating me. I admit I put my foot down for a few hundred yards before I turned off down my street. As I was going down my street nice and easy STOP engine, low oil pressure light popped up. I turned off the engine and rolled it down the street and parked it up. Checked oil and oil level was fine. It happened to a mate a few days ago and he had it towed to a specialist to have it looked at. It was confirmed he had a blocked oil pick pipe which was replaced and new oil. Total cost 450. Ouch. I wasn’t going to pay that much money so I thought I would ask him for his invoice and got all parts from stealers. I also read on another forum to clean the sump.
Parts needed:
New oil pick up 06F115251A,
Gasket sealant SD176404A2
Oil filter
Castrol edge FST 5w30
Oil sump plug
Degreaser
Carb cleaner
Few days later me and my brother got to work. Weather was perfect, sun was out and a good day to fix the car. Got the car onto some axel stands and drained the oil, removed oil filter. Took off the oil pressure sensor and removed the sump. All but 2 bolts are pains which are located near the gearbox/Flywheel. The sump will come off but you will need to pry it a little. Had a look at the sump and it was full of gunk. Sorry I couldn’t take any pics. I drained the remaining bit of oil and got on my hands and knees and started to scrub the sump clean. Sprayed it with carb cleaner and used a toothbrush and a metal bristle brush to get all the burnt oil off the side of the sump. It was this burnt oil that caused the low pressure warning. Bits of the burnt oil had started to come away from the sump and were gathered at the bottom of the sump and in the oil pick up pipe. After an hour of cleaning I turned on the pressure washer and gave it a good blast. The sun was out so I left it to dry whilst I flushed some oil through the engine. I cleaned away any old sealant both on the sump and the around the engine, oil pressure sensor cleaned and put back in along with the new oil pick up pipe and oil filter. Sealed the sump. I didn’t over do it with the seal. I used a line around the whole sump and quickly got it back on the car as this stuff dries very quickly. Left it for a few hours and went to get cleaned up and have a bite to eat. You need to leave it for at least 30 minutes before filling it with oil. After a well deserved break filled the engine up with oil and cranked it up. Left it to idle and then switched engine off and topped up with some more oil. Oil levels all ok started the engine and left to warm up before I tested to see if it had fixed the problem.
Took it for a drive after it was all warmed up and it drove 100 times better than before. I couldn’t tell you how pleased I was. The car pulled a lot smoother and was so much more responsive. No oil pressure warning and no matter how hard I drove it.
Something I would recommend to all MK5 GTI owners who have been on a long life service. My car has done 100k and has FSH. But I’m so glad I got it done because a few days later the nephew broke down in his MK6 Golf R, low oil pressure. Got it to stealers and was told he needed a new engine. The car had only done 24k and is just out of warranty. Goes to show it can happen to anyone.
Just thought i'd share my experiance.
