Disco 200Tdi

I'm trying to replace a Disco 200Tdi temp sender. I went with John B's part number b/c I thought that the Defender and Disco 200Tdi's would be the same. Not the case. The photo shows the difference. I double checked the part that eGauges sent, it was 323-026D. The 026 was too long to even begin to thread in. I didn't match the threads up, guess I should do that.

Anyone know the correct VDO sender part number for a Disco 200Tdi?

Stephen,

What I found out was that at NOT (normal operating temp), the resistance sent from the original sender was 90 ohms. As the engine cooled down, the resistance went up to around 200 ohms. I am going to experiment with some small resistors in series to up the resistance therefore moving the needle to match whatever the infrared temp gun reads on the waterpump housing as compared to the VDO gauge.

I'll post my results as soon as I get a chance to play around with it. This way we can just use our existing senders.

Thanx Neil, I am awaiting a mudpod for my vdo guages, and have my stock temp guage hokked up now. I guess this is not accurate according to my guy in uk. He says there is an adaptor and is looking for one untill I can find the disco 200tdi guage parts # source.

Steve,

Could you post a shot or two of how you fit a disco 200tdi in your NAS 90 ? Just looking at the clearance to the steering shaft and box it would appear that would take some ingenuity that's beyond my realm to put one of these in a lhd truck. Very curious to see how you did it.

Doug, I will try to get some shots tomorrow. I actually did not do the work, My freind (Matt Hawkes) who is a LR Master Tech in maine did it with Guru (in New England) Bob Veil s help. Look for pics tomorrow. The Steering shaft we just had machined in a straight fashion and a bit of cutting to clear the turbo. Have got some tweaking to do on cooling and intake filter arrangement. She is going to Matt Browne for ip tunning and all. I will neve drive a v8 again after owning the tdi........I likeee

IT looks like the steering fits from the pictures. Is this true?

tdi fit

It is mated to a short bellhousing on the factory R380(original tsb replacement I think) with a short input shaft. Works great w/ GBR 4.10s and arbs I got from Jeromy in Texas. The truck is acually a bit quicker than it was with the cammed V8

The steering shaft is a custom straight job that Matt had machined and fits great.

Hi Neil-

Any resolution on this? If your ohm numbers are right, I wonder if VDO Gauge Part No 310-104 (220 deg) would work OK as it has a range of 240-33 Ohms. Here's a thread about drilling and tapping the original sender:

Hey Stephen - what ratio is your LT230?
