TheRecklessEngineer Posted November 8, 2006 Share Posted November 8, 2006 Just put my disco through an MOT. During the smoke test, the tester had to rev the nuts off the engine to get the oil temp to over 80 degrees. At idle it sat at 61 degrees. Is something wrong here? I would have thought it would have sat much higher than that. Jammed thermostat? Quote Link to comment Share on other sites More sharing options...
Andy Posted November 8, 2006 Share Posted November 8, 2006 could be, early Tdis seem to have had 82degree stats anyway. i replaced mine with an 88degree one, heater is much better now as well. had you driven far to the test center? seems to take 20+miles to get mine fully warm.

TheRecklessEngineer Posted November 8, 2006 Author Share Posted November 8, 2006 Yup, and it had an 'italian tune up' on the way there. Maybe an 88 degree stat would be the way to go. Quote Link to comment Share on other sites More sharing options...
JST Posted November 8, 2006 Share Posted November 8, 2006 i thought they had dropped (as in lowered) the engine oil temp requirements. Quote Link to comment Share on other sites More sharing options...

JST Posted November 8, 2006 Share Posted November 8, 2006 the engine oil temperature measured by a probe in the oil level dipstick tube is to be at least 80°C, or normal operating temperature if lower (60°C minimum). Testing an engine below normal operating temperature may affect the test result so could use 60 deg then for pre '79 and after '79 is just says . the engine is at normal operating temperature Quote Link to comment Share on other sites More sharing options...
western Posted November 8, 2006 Share Posted November 8, 2006 my tdi has never had a temp probe shoved down it's dipstick tube, the emissions test is always done as soon as possible when I arrive, after a long run it'll be at normal operating temp anyway.

simonb Posted November 9, 2006 Share Posted November 9, 2006 Had my mot on the Tdi yesterday. Printout showed oil temp at 67.1 degrees, and it passed on everything. Quote Link to comment Share on other sites More sharing options...
