Title: BLOODY OIL TEMP!!!!!!!
Post by: rongti on 01 December 2008, 09:15

OK so after a dodgy readout for the oil temp (was reading very hot when water wasn't) I have changed all the sensors for the water and oil and checked all my earths.  I even went so far as to get a load of new connectors for the wiring loom and re-loomed a load of stuff and replaced a load of fuses.

Now instead of the oil temp reading hot (110-120), it now reads cold (never gets above 68)!  Has anyone got any ideas...?!  Surely this has to be wrong   :huh:!?

Hi mate sounds like ur having fun  :undecided:
Where did u get ur sensors from? I got an oil temp one from gsf and it wouldnt read any higher than 68 degrees fortunately my old vw one was ok so put it back on. I think the sensor is rated from 50-55 degrees to somethin like 190. If its not as vw sensor try and get one and see what happens they are not very expensive.
I would say a normal operating temp would be high 80's.
Hope u solve the problem and i hope this helps  :wink:

Yeh I've heard only bad things about GSF sensors but thought that the oil one would be fine form there as it's so simple.  Obviously not :angry:!  Looks like another journey to VAG then.

Cheers.

have a look at the sensor, what colour is the collar? MFA sensor has a white colar, coolant temp has a black collar.  Different ratings :)

It annoys me that GSF can't even supply something that works correctly.  Fair enough it's not a VAG part and it's made at reduced cost, but surely the basic fact that it works is a pretty important design concept.

Mine always read 112 even when pootling along. I suspected this was wrong because the rad fan hardly ever came on. I went to GSF and bought a new oil temp sensor part no. 93490 (which was different to the sensor I took out). At first I thought it was OK until it never went over 70oC on my 25 mile commute. I mentioned this to GSF but they were adamant it was an 'equivalent part'.

In the end I bit the bullet and forked out £20+ for a VAG oil sensor which was different yet again to the other two sensors! Now it reads 98 on the motorway and 90 when pootling. Third time lucky  :grin:
