flashing oil warning light

started flashing when i started it up the battery light stayed on too (but a new alternater sorted that)........was all fine when i parked it up........still plenty of oil pumping up to the top end of the engine...........keeps flashing when you unplug from the pressure sensor (pressuming the sensor is the one by the oil filter)...........its a 1.9 td abl engine btw........



any info appreciated.......

thanks in advance.......

cheers

thats wot happend to mine..............flashed on and off a few times then the battery light came on constant and the oil light started to flash.........new alternator sorted the battery light out but the oi light is still flashing.............not had chance to look at it yet.........wil keep you posted when i get to sort it or let me know if you get sorted..........



cheers

happened on my t3 it was just the high pressure oil light cable had been cut by the fan belt...took 5 mins to fix with a swiss army knife. Im sure t4s are more advanced.

ok sorted mine..............the alternator on mine has  three cables goin to it...........a big one secured by a nut and then then two other single small cables that each plug in..........it was the bottom one that wasn,t clipped home correctly.............hey presto no more the flashy oil light............

(joy!)   Sounds like VW up to their old tricks - I remember on the Beetle Starter motor they have a puny wire thats quite key to the thing working and its just a spade connector !!   Duff question but where are the oil pressure switches on the engine - sorry the manual really is pants for identifying stuff like this? Tells you about the 2x types of switch but not where they are located?

the switches do go m8, i changed mine a few time on the filter and was still the same, then fitted a new pump and it was the same, then tried the one in the head and all is well, the switches are about £6 to £10 from any motor factors £20+ from VW dealer, if the oil level is right and the switches don't make a difference then it could be your pump, with any luck it wont be that, the switches are the easy thing to check and not a lot of money, oh they are coloured as well make sure they are the right ones

Hi - got it serviced - runs so sweets after just an oil  and filter change (well as sweet as a diesel can sound anyway!!  ) Garage had a look no loose connections and they say the engine is fine and pressure is fine? No lights or anything but then last night - both lights came on - the alternator was glowing a bit and the lights dimmed slightly in the instrument cluster? So I switched down to side lights from full lights and no change - then switched back up and after a second or so the lights both went out - the cluster brightened a little no more lights rest of trip? Revving engine does'nt make any difference - so its got to be a lose connection? I am inclinded to think its the Alternator contacts , or recifying circuit?

must be something to do with the ecu, the two thin wires are energizer going to the alternator and on that goes to the led for the charge light, on pre 96 (before ecu and transponders)
