Hi,

My omega is idling at just under 100rpm when I switch on in the morning, was just over 500rpm last week. Blocked breather hoses? Anyone like to point out where to check? Diagram maybe? :-/

Cheers,
Iain

Idle increases as it warms up? Suspect CTS?

(Note: being a BMW engine, most failing or failed sensors do NOT bring on EML)

Hi,

CTS? Idle doesn't increase, soon as throttle is moved it dips back to 500rpm

Coolant temp sensor.  2 CTS on that beemer unit, both in head. One (the single wire one) is used for dash, other (2 wire) used by ECU

[TheBoy]

If yours is paperclippable (about 50% of TDs are), iirc, cts is a 15

Hi,

The stat is gone on it, nothing to do with that would it? Problem to repalce? Any need?

Stat is easy on TD, though unrelated to your idle

[Omegatoy]

if stat is stuck open cts will never get to correct temp!!!

Hi,

Might be the problem then, going to get done this weekend, after i've managed to get the fan off , and the rear discs and shocks done, and the steering idler

Cheers,

Don't forget - viscous fan is left-hand thread.
A sharp jolt usually starts it undoing.
