Thread: 300tdi disco EGT

ok changed to Celsius..sits at around 104/110 at idle.

can you guys tell me what your limits are set too?

it would be really helpful to, to know what sort of temps I should be expecting on average hills, highway driving that sort of thing..

your experiences (I appreciate its not black and white and everyone will differ slightly) would be appreciated

Recommended maximum 720C, can reach 700C easily if flat out up a steep hill.

Lou,
Unfortunately that question is like the old chestnut "how long is a piece of string?" there are simply too many variables.

When you get a chance, try driving to keep the egt as low as practical, without suffering too great a loss of performance and without lugging the engine. You will find your right foot can make a big difference - you might also like to think about how that affected economy.

Lou,

John has hit the nail on the head there, everyones vehicle is slightly different, as Beeutey said HIS EGT's are around 700, I would want to see 600 to 650 for a Tdi auto though, and basically the harder you drive and the more fuel is wound on the hotter it gets...and aconomy will suffer a little too. I'd suggest 'suck it and see' and make adjustments etc along the way.

guys I appreciate all this hence why I said I know everyone's car is different but unless I know what is and isn't an expectable level how can I judge?

hence why I was asking what people get if my plod gets 600 but mr lead get 750 then I know that I have a reasonable safe parameter

thats all I was trying to get out of that question

Its kind of useless me fitting this gauge if i don't know what the unacceptable levels are

Lou,

Thats why I mentioned 650 degrees, that would be MY safe prolonged temp. 720 degrees is an 'industry' recommended max. All these temps are 'upstream', before the turbo. That is where your probe is if it is in the EGR port.

You can loose 150 to 200 degrees across the turbine, so if you were measuring downstream, you'd start backing off at 550.

have a look on the thermoguard website.
They give some very detailed info at what happens to your motor and what temperatures are considered save.
they tell you what makes it hot and how to very quickly drop temperature should you find it climbing.
The website is full of engineering detail and are not just hear-say.
They have probe up-stream same as you and explain how the intercooled air improoves performance. ThermoGuard Instruments

Go there and all your questions will be answered- trust me.
