This behaviour is normal, oil temp will always rise under strain but I wouldn't read too much into what the gauge is saying, they're not really accurate - the gauge is indicating a rise in oil temp, which is correct, if it stayed 'high' then it would need looking at but the fact that it drops again...

Mine doesn't have any numbers between 90 & 140, but there are a couple of 'divisions'. As the scale is pretty non-linear, it's not clear to me what they represent. My car usually sits at the next mark up form 90, (which I guessed to be 110). If I go really gently, it drops a bit and climbs half way...

I have a 406 110 bhp diesel estate. Everything is fine, oil temp and water temp.... except when I tow. The oil temp creeps up to approx 120 (130 on hills) but the water temp stays the same at 90. Has anyone else had the same problem or does anyone know of any additional cooling kits I could purchase...

Is it broken or has the spring gone?
Look on this site for a quick fix if the spring has gone.

I am planning on fitting some on my 406 estate cause the missus wants some.
I will let you know how I get on.

I am on my second 406. The first was a petrol d8 and the petrol gauge used to fluctuate a bit on that but on this d9 406 HDI Diesel the gauge seems to be worse. It was showing 3/4 the other day and I called in to top it up and only put about 2 litres in and it came up the filler pipe! Any ideas anyo...

Thanks.

Reassured.

Hi, I am reletively new to this forum and reading through quite a few people refer to D8 and D9.

What is a D8 and D9?

I have a 406 2.00 HDI 110 estate.

Great site with plenty going on.
Just recently bought a 406 GTX HDI Estate after owning a 406 2.00GLX Petrol estate.
I think the cars are good and the diesel is excellent for towing.
