Nonimouse Posted April 27, 2020 Share Posted April 27, 2020 I'm on my 11th 200 tdi since 1992. In the previous ten, I have never had to change an oil pressure switch. My 11th - a 1993 Disco 5 door, I am about to fit my third in 2 years. I'm using Intermotor switches, not Britpart. Every time one fails, I have to double check all is ok, so have the joy (and mess of using a oil pressure test kit. Pressure is fine 50+ psi on cold start tick-over and 38 psi on warm tick-over. Using Shell Rimula 10W40 I've ordered another switch - OE from Bearmach, but am contemplating fitting an electric oil pressure gauge to avoid annoyance in the future I'm aware that 200tdi owners are now a select few - has anyone else had this problem?

Bowie69 Posted April 27, 2020 Share Posted April 27, 2020 Intermotor stuff is often actually complete rubbish, in my experience. ...and I used to work in an independent car accessories/parts place. Take V8 dizzy caps, fail within a few hundred miles. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted April 27, 2020 Share Posted April 27, 2020 Try Britpart? 2 Quote Link to comment Share on other sites More sharing options...
Nonimouse Posted April 27, 2020 Author Share Posted April 27, 2020 To be fair, this style of pressure switch is famous for it's unreliability - but I've never had problems until this vehicle/engine Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted April 27, 2020 Share Posted April 27, 2020 I've just had one fail as well , not been in long I put it down to just a duff one as I thought they where a good brand . 1 Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted April 27, 2020 Share Posted April 27, 2020 I replaced mine a few years back, used a genuine one - no issues so far. Quote Link to comment Share on other sites More sharing options...
Snagger Posted April 27, 2020 Share Posted April 27, 2020 Mine still works, and was fitted long before I bought the engine in 2007. I think it is original to the engine, K registered donor, so probably around 28 years old. I’d pony up for a Gen Parts sender. 1 Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted April 28, 2020 Share Posted April 28, 2020 I replaced mine last year as it was leaking oil. Now the replacement is doing the same. Time to buy a real one methinks. Anyone got the part number as I'm too lazy to search for it 😆 Mo 1 Quote Link to comment Share on other sites More sharing options...

Snagger Posted April 28, 2020 Share Posted April 28, 2020 That’s not bad - I was expecting it to be over £100 from the build up! 😂. Certainly a lot cheaper than repeated replacements or rebuilding the engine because it didn’t want about low pressure... 1 Quote Link to comment Share on other sites More sharing options...

Snagger Posted April 28, 2020 Share Posted April 28, 2020 I put a worry gauge on mine donkeys years ago, against advice of a specialist. Had good pressure on my 12J, but I’ve never been happy with the readings on my Tdi. It’s probably harmless and may be an indication error, but it’s going to cost me more money just to get a right reading because of my OCD!

Peaklander Posted April 28, 2020 Share Posted April 28, 2020 How about this one on eBay here for £17.99 delivered? It's a new genuine one. 1 Quote Link to comment Share on other sites More sharing options...
Nonimouse Posted April 28, 2020 Author Share Posted April 28, 2020 I've already ordered am 'OE' unit of Bearmach. Most likely an Intermotor unit in a Bearmach box/bag Nick, I'm tempted to leave the pressure tester hooked up permanently, but under the bonnet Quote Link to comment Share on other sites More sharing options...

Nonimouse Posted April 28, 2020 Author Share Posted April 28, 2020 Just looking at the LED flat Oil Pressure doofah and it also does water temp, boost and EGT I have a second water temp sender on the lower LHS rad tank I could do with a BOOST measuring doofah And an EGT sender is an easy thing to acquire/fit Quote Link to comment Share on other sites More sharing options...

Mo Murphy Posted May 1, 2020 Share Posted May 1, 2020 @Nonimouse So, oil pressure switch arrived today. No makers marks on it except for the part no. stamped on one flat of the hex and 41/12 stamped on the opposite flat, though I've no idea what that means ! The white housing with the spade connector above the fitting feels like ceramic rather than plastic, though it may be a hard plastic. It accompanied by an aluminium sealing washer nattily punched off centre ! Packaging indicates it is Polish made. Now all I have to do is wait for the lock down to finish so that I can get up the farm and fit it 🤐 HTH Mo 1 Quote Link to comment Share on other sites More sharing options...

Sigi_H Posted May 1, 2020 Share Posted May 1, 2020 I had a defect pressure switch on my Moto Guzzi years ago and one on my 200Tdi too. Since I do not really rely to those switches I installed a direct pressure gauge. I drilled a hole in the oil filter carrier and connected a simple manometer (6 bar) as pressure gauge.
