Also had the STOP light coming on due to potential low coolant. It seemed almost randomly!

However it happened on inclines mostly which could be exacerbated with a trailer.

It was the coolant switch in the radiator. My rad had a slight leak and just needed topping up every 3000 miles (not worth replacing on a car a bought for 400GBP)

As a run around best car I've ever owned!

Having had the old 405 1.9d. I knew these beasts were reliable and resourceful (to the point people are now trying like crazy to get these old cars, because they want to run them on used cooking oil / used engine oil! Yes used engine oil!!! Blimey!)

Drove my 96 405 GTX TD estate home after winning it on ebay for £127, and wow was I surprised! It handled like a dream!

Picked up faster than I thought it would! (was expecting no response) LOLOL

Everything worked (except air con).

Even had a 6CD changer in boot (original radio with car!)

Just MOT'd it, and it needed a bush! Wow, this old Trooper has not missed a beat at all!

It's showing a few war scars, but I would say if you come across one, buy it! For your money you won't go wrong!

All its needed is 2 new tyres, a new battery and a end cap for injector returns (would not start in mornings after the cap split letting the derv siphon back to the tank).

As for the 210,000 miles it's done, it drives like it did new! Just as long as you remember to change the oil every 6k or they don't like it...

I'd have another any day!!!

I never heard of a 2.1 diesel engine in the 405.

Was it a slightly larger variant of the 1.9 XUD? This engine was always known for being extremely reliable, as well as fast, even the naturally aspirated versions.
