How much oil for oil change 2003 Jetta TDI

yes- check your oil level - sounds like they didn't fill completely or something is loose and leaking oil out

Most guys just replace the sender, as tools to measure the old one would cost more than the replacement sender.

Most guys do not actually test the sender, as it is somewhat hard to do, as you must know the pressure to evaluate what reading you get.

IF you suspect you have incorrect oil pressure, test the pressure by using an external pressure gauge. If pressure is okay, just change the sender.

If the pressure is NOT okay, shed tears and commence surgery to find cause.

PLEASE DO NOT add any oil to the fuel,use redexe/wynns diesel additive to clean the lines/injectors/turbo vanes,but burnt oil will stick to the turbo vanes and could cause failure.....just use 10/40 semi synthetic oil as normal and change regularly.also let the car tickover for a min or two after a HOT run....

don't know about the MPG it could be a lot of things. I have a 2001 Jetta TDI. You should NEVER change the oil at 3K miles. VW recommends 10K miles for a reason. The Synthetic oil has additives to remove varnish and it does that but it needs some time to replace the varnish and properly protect sensitive engine parts. 3K is oil changes are not a good thing for a TDI......Just use the right oil and change at 10K

thats nothing for a tdi the a/c compressors are prone to seizing , oil pans are low to the ground hit everything easy to change though

Go to www.tdiclub.com and read, read, read. Anything and everything you ever needed or wanted to know about you car is there. Those guys REALLY know their stuff.

valve seals are going. when car sits excess oil gets past the valve seals then when you staRT up it burns the oil off then runs fine and no more blue smoke. It is fine to run like that had the same in a dodge caravan 1996 6cyl. ran another 100 000 km. and still ran fine got rid of it for other reasons.

Change it every 10k miles. You have to use 5W40 FULL SYNTHETIC oil. Not just any oil! You can buy Shell Rotella T 5w40 or Mobil1 5w40 Turbo Diesel Truck oil at Walmart. Both of these oils meet VW's TDI oil requirements.
