I don't enjoy being the bearer of any bad news, and I truly hope that what I think happened didn't happen.
It is completely possible that when the oil change was done, either the pan plug or the oil filter were not screwed on tight. This enabled the oil to leak out of your engine, causing lack of lubrication. When the bottom of your engine stopped being lubricated it caused a spun bearing on crankshaft at piston rod bottom. This is just a guess on my part since you stated oil pressure light and loud noise. I do feel that you should call the place where oil change was done and report this problem to them. DO NOT drive the car, let them come to you to inspect or tow back to there place. GOOD LUCK FRIEND.

SOURCE: 1998 lexus gs300 multigrade oil to FULLY SYNTHETIC oil

You can Safely Convert over to Full Synthetic and it will be Just Fine. It will actually be Better for the Higher Mileage Motor. Just make for sure that you Drain all of the Old oil out as Possible Before you refill with the Synthetic. A Little Mix will not Hurt the Motor at all. Please Rate My Response! Thanks!

SOURCE: loud knocking or tapping sound when engine is cold

Take our oil pan off from under your car and there should be 4 to 5 covers over a rod bearing. wiggle each one of them and find out which one is loose. take that cover off of the one that is wiggling and get the rod bearing out. order a new one from auto zone and replace it. The knocking in your motor can end up where you will need a whole new motor. so get it done before its to late.

2006 5.7 545rfe trans. Last wed replaced solenoid block pack. Went great wed, thurs but friday morning got po700 and po876 code and has gone in limp mode. Any suggestions? Please help


Possible front transmission pump getting bad. This will also cause accelerated wear on the clutch packs. Talk to your local Tranny repair shop for advice. The solenoid/pressure switch assembly you changed relies on pump pressure for its operation.

Oil min light keeps coming on


What kind of oil? Is its not synthetic it's wrong...the Audi engines have a small oil pickup tube and the cheap oil gunks up the engine and clogs pump screen causing light to come on eventually engine failure....you need to flush engine ....you can use kerosine or go to parts store and tell them you want to clean the internals of gunk ...pour in engine oil let run for few min drain oil ...buy cheap oil for this do same thing 3 times ...when light goes off your done fill with fully synthetic oil and you just saved your engine ...only synthetic oil

This could be a low oil pressure problem or a failing oil pressure sending unit (sensor). It could even be diluted engine oil. If it has been a while since the engine oil was changed, then change the oil and filter. If you still have the problem, then perform an oil pressure test and measure the actual oil pressure. It should not drop lower than 7 PSI at idle with a warm engine. If it does, then there is an internal problem with the engine like failing oil pump or worn bearings. If the oil pressure tests ok, then have the oil pressure sending unit replaced.

Flashing oil light audi a4 1997 on the dashboard


Your oil pressure is low. It could be your oil pump going bad or you could be just a bit low on oil. Be sure and top off the oil with a good synthetic oil, or, to be safe, get the oil changed (could also be sludge).

Hi just bought i999 1.6 audi a3 and it has started to pulse when idling and oil light comes on when engine reaches nornal temp what could this be please help


If by pulsing you mean that the idle is fluctuating up and down, this is caused by oil/sludge build up in the throttle valve. To rectify this remove the intake pipe at the throttle valve. Use engine cleaner/degreaser on a rag to clean out throttle valve around throttle butterfly. Open butterfly manually to assist access. The oil pressure light coming on is usually caused by the oil pump pick up becoming blocked by carbon and sludge in the oil sump. If you have a suitable oil pressure gauge, check the oil pressure at the oil switch. Oil pressure should be 3.5- 4 bar at 2000 rpm at operating temperature. If pressure ok, Pressure switch may be faulty. If pressure low you will have to remove oil sump and clean out or replace oil pump pick up. If not done, may result in major engine damage. Sludge and carbon build up caused by oil not being changed often enough. Best to use a synthetic oil.

My oil service light came on a few days ago than today my car stopped while i was driving it i was able to restart it but now its making a weird sound


HI, you dont say what the sound is like, Have you checked the engine oil, this car as the PD engine fitted and only use good fully synthetic oils.it could have gone into limp mode for lots of reasons, go to a reputable repair centre and get the car checked out, good luck.

Try to change your oil and add one quart of lucas oil that will quiet your engine and will lubricate your valves too.
5 quarts of regular oil change. Pour 4 quarts of synthetic oil 5W30 and one quart Lucas Oil.

Oil light comes on in hot weather


Changing the computer doesn't sound right. Most likely a bad oil temp sensor. Make sure you are using the recommended weight (synthetic) oil.
