Thread: Essential gauges for Tdi ?

Boost gauge would be low on my list.....same bracket as a taco.

I replaced sensor temp gauge with a mechanical temp gauge.....solved earthing issues

I also went with a digital EGT

Update your existing water temp gauge to a VDO mechanical. You will need the sender adapter as well.

Also remove the clock and put in a VDO tacho.

I also have a EGT plus a boost gauge.

I purchased all 4 gauges (and temp sender) from Otto Instruments in Brisbane. John who runs the joint, is a Defender driver and a member of the GCLRO. Not sure if he visits AULRO much any more.

A low coolant alarm is a must. The sensor screws into the bung on top of the radiator on the passenger side

A boost gauge is only really necessary if you intend to ‘play’ with tuning, otherwise they’re just for curiosity sake.

Any particular one you'd recommend?

Errr ... yes and no.
Can be handy to catch a boost leak as it develops rather than once it has become an issue.
Splitting hoses, or pin holes in intercooler, or whatever.

"Gee I wish I didn't have that piece of information." Said nobody. Ever.

If if I didn't have the wife to worry about my dashboard would look like the cockpit near the left hand seat in an early 747. More data please.

Again can anyone recommend a particular low coolant alarm?

I'd have a seperate temp guage so a simple light would be fine, and with a buzzer as well possibly even more useful.

Sometimes low tech is the best tech.

In my old 300 I just plonked a Jaycar float switch into the header tank
You can run them NO or NC quick 12V from ign switched live to the switch in NO setting to a buzzer in dash to earth

Float Switch | Jaycar Electronics

When level in header drops (which it does before it drops in the hoses) alarm goes bing.

I’ve been to lazy to put same into the TDCI
I keep intending / thinking of replacing the header tank with aluminium and installing a float switch

It’s on the list
