1Z oil switch ratings.

80 diesel 1Z engine......can anyone confirm that the oil pressure switch on the top side of the oil filter housing is 0.15-0.35 bar.....and the lower one is 0.75-1.05 ??
Thanks.

Giving us the year would be helpful for next time.

Based on guessing 1996:

1. 028919081D is a blue, one pin, M10x1, 0.25 Bar.

2. 068919081A is a grey, one pin, M10 x1, 0.9 Bar

I was assuming all 1Z engines would be the same, you're right with the year.
Many thanks for the info.

The thing is you don't start a parts search on the engine, you start on the model, e.g. Audi 80 and then the year. Then and only then can you start searching on the engine.

Anyway, I lucked out and you have an answer to your question. Hope that it works out for you.

Have replaced the upper one but wanted confirmation on the pressure ratings as have been supplied the wrong lower one.
Hopefully get this sorted soon.......oil warning light comes on intermittently.full brightness then fades 'till it's out.....no pattern to this, hoping the switches will sort it?
