*Glenn* 854 Report post Posted December 10, 2009 how about you temp gauge does it sit on or just above the blue or will it get up to 1/4 or 1/2?? All BMW's run at half way (middle of the guage) if everthing is working properly Quote Share this post Link to post Share on other sites
Mark 178 Report post Posted December 10, 2009 How diagnost fault crectly? but mine is working i think jus want to chek it is proper. Mine has testy ligt 12 volt did this right or not ? Nun morse help from peples I think I found your problem OP... these guys have been drinking your gas. Quote Share this post Link to post Share on other sites
Wervie67 0 Report post Posted December 10, 2009 what would be the average time for an e30 to warm up glenn? mine gets to halfway but it can take a while Quote Share this post Link to post Share on other sites
e30ftw 393 Report post Posted December 10, 2009 ^ LOL There is 2 sensors for temp, Brown one is for the gauge cluster and the blue one is for the ECU. It's supposed to be measured by resistance at certain temps, not power. Quote Share this post Link to post Share on other sites
*Glenn* 854 Report post Posted December 10, 2009 (edited) what would be the average time for an e30 to warm up glenn? mine gets to halfway but it can take a while Really depends on ambient temperature, engine condition and how its driven and whats turned on at the time... like AC Edited December 10, 2009 by *Glenn* Quote Share this post Link to post Share on other sites

Wervie67 0 Report post Posted December 10, 2009 (edited) Really depends on ambient temperature, engine condition and how its driven and whats turned on at the time... like AC its PFL so no ac. usually around mid morning (7,8am) down in the deep south, so only a couple of degrees just a bit annoyed cause it uses ALOT of gas when its not warm and usually dosent fully warm up by the time i get to school. about 5km away?

*Glenn* 854 Report post Posted December 10, 2009 My wife resists all the time ... how do I measure that? Sorry John.. I had to say that You need to be more specific with your advise. Your right... you measure resistance at a given temperature at the sender unit.. I dont have those values here at home though. Quote Share this post Link to post Share on other sites
hotwire 352 Report post Posted December 10, 2009 Could please expain how to check this falt ? Resitance values - approx: 3ish k ohms at cold, 250ish ohms at operating temp. Blue two terminal temp sender. Single terminal sender is for gauge Quote Share this post Link to post Share on other sites
e30ftw 393 Report post Posted December 10, 2009 I have different values for the bosch engine temp sensor? 187ohms at 100C. 1707ohms at 30C. Quote Share this post Link to post Share on other sites
hotwire 352 Report post Posted December 10, 2009 I said ish. You will find when stone cold resistance will be high 2k's. At normal operating temp will be around 250ohms Your figures will be correct - 100C is higher than normal operating temp - hense lower reading Also cold engine is below 30C - again - reason fo higher reading. As long as the unit is coming down to a low reading - this won't be the problem Quote Share this post Link to post Share on other sites
_ethrty-Andy_ 2122 Report post Posted December 10, 2009 ok some basics.. but could affect gas milage: tyre pressure, wheel alignments, fuel filter, leads, spark plugs dirty trans oil, injectors, leaks, o2, MAF, dirty diff oil etc... is your car running lean or rich?? exhaust smells like gas?? oh and are you carrying a dead hippo carcas in your boot? LOL all of the above has been worked on/replaced in the last year, except the AFM (my first idea) and the fuel filter which may be a good time to replace it as said above, i have no sence of smell so i cant tell you that :S not a dead hippo. just a few subs and amps. but the car has always had bad economy even when it was stock standard. havent noticed any increase in consumption because of this weight Quote Share this post Link to post Share on other sites
_ethrty-Andy_ 2122 Report post Posted December 10, 2009 Memory fail. Seriously, My m20b20 used to be the same as this.. It was slow and sluggish, blew smoke up high in the rev's, spat unburnt fuel when idling. The fix, threw that motor. M50/52 next year.. i have it sorted out haha Quote Share this post Link to post Share on other sites
_ethrty-Andy_ 2122 Report post Posted December 10, 2009 I remember talking to a guy, he didn't know he had a fuel leak but noticed it one day when his car was running under the car, it was dripping slowly but evaporating as it hit the ground. So you pretty much would never notice. Maybe run the car and have a look around the rear fuel lines, lift the rear seat check under the inspection cover for the fuel pump, follow the lines under the passenger side of the car to where they go rubber again into the engine bay. will do Quote Share this post Link to post Share on other sites
_ethrty-Andy_ 2122 Report post Posted December 10, 2009 how about you temp gauge does it sit on or just above the blue or will it get up to 1/4 or 1/2?? It chills on half way, sometime goes around 3/4 when i drive hard but will then go back to half Quote Share this post Link to post Share on other sites
_ethrty-Andy_ 2122 Report post Posted December 10, 2009 can i get an agreement on the temp sensor ohm ratings? parts list: Temp sensor Fuel Filter Possibly AFM if those other two dont work Agreed? I expect the 3.5ish LSD to make a difference over the 4.46 open as well. if i get exactly 200kms now, (calculates: 200*4.46=890/3.6=247kms ) can i expect to get 247kms when the LSD is in? or doesnt it work like that?

Temp sensor readings - as I stated. If you read my second post - all the figures compute thereabouts. It is entirely dependent on engine temperature at a specific time. Again -As long as it comes down to around those hot readings - it is recognising a hot engine Quote Share this post Link to post Share on other sites
