it is in limp mode becasue of hte egt code? it comes back straight away?

It doesn't come back straight away. I can clear the codes and sometimes they won't come back for a while. From driving it I can tell when the EGT sensors have thrown a code, sometimes it pulls like a train, and other times it holds back a lot..

Sorry to butt in again but this is exactly the same as mine, clear code and sometimes back straight away other times takes weeks.

Did you resolve this?

Just come back from 1000 mile round trip to France, checked for codes and there were none.

Went for a blast as I took it pretty steady whilst away and the "short to ground intermittent" code came up on the same egt again.

Now wondering if either the egt is getting too hot when I really floor it or movement in the engine when changing gear at high revs is tweaking a wire somewhere causing a bad circuit.

I fitted a MAF sensor and fitted a L/H EGT sensor while at MRC and after a 1700 mile trip to the Nurburgring I'm glad to say the car didn't miss a beat. It appears the MAF sensor may have been under-reading making the car run weak which killed the EGT sensors.

Cheers for the swift reply!

Glad you resolved it, my problem would seem to be different as I replaced the MAF and the EGT sensor at the same time.

The old EGT gave the same fault code as the new one even after replacing the MAF and last time I logged it my MAF was giving higher than expected readings (232 std car) which I would have thought would richen the mixture and so protect the EGT's.

As I said the fault only seems to appear when I really boot it in second gear, clear it and drive like a "sensible" person and it will stay cleared.
