Oil Pressure Gauge Giving Up?

[DanRM 0 1 Cars]

Hi, when I first bought my 1.6gti last year, the pressure gauge used to go up and down with the revs, now it just stays at the 2nd bar and rarely might drop down for a second when changing gear. But this morning I noticed that the needle drops right down to the light and stays there for a while then randomly jumps back up to 2nd bar again.

 

I managed to do 5miles on the way to work before it came back up and has done this about 6x today, however when it drops down the warning light doesn't come on (it does with the ignition on so i know the bulb is working), would this be problems with the gauge itself or something else?

 

Cheers

 

 

Oops just realised I put it in the Mods & Upgrades by accident

Sounds like a bad connection to me. Might be that the terminal has come loose from the tab on the sender, and is just making occasional connection, or the wire could be broken further up. Or - more likely if you still have the OE brown multiplug that sits above the gearbox - it could be a corroded connection in the plug.

have your oil pressure checked just in case, i had a similar problem recently with a customers 1.9 gti and it was the sender unit for the guage which is on the front of the block next to the oil pressure switch, its around 80 quid from peugeot.

My money is on the brown multiplug. It is a common issue on a 205

Where is this multiplug? Mine seems to go up to half but sometimes flicks down to nothing and then back up, but the warning light does come on. I hope it is a multiplug problem!

.... brown multiplug that sits above the gearbox...
