Roach Posted February 2, 2018 Report Share Posted February 2, 2018 Hi there, new here and first time owner of a bmw e46 53 plate 320d touring. I recently got the car, and noticed when driving the temp gauge only got to quarter way on the gauge. Ive just done the stats (engine and egr) and bled the system as per the procedure I read on here countless times. On the driveway the car get to 12 o’clock on the gauge and blowers are lovely and toasty, great right, all fixed??..... But when I take it for a drive, the gauge barely gets over quarter, and even fluctuates about between the first 3rd of the gauge, it drops when I come off throttle and go round a roundabout etc?? What’s that about? I should note I’m running it with no engine covers and no undertray as I was checking nothing was leaking... I can’t see how that would affect it tho. Is there a CTS on these cars that could be playing up? What should I check next? Have I put another duff stat on? help please. roach.

Roach Posted February 3, 2018 Author Report Share Posted February 3, 2018 Yeah it’s got the egr stat, I also changed that one for a non gen part. Ive just ordered two genuine bmw stats, I’ll whack em in midweek and see how I get on. Quote Link to comment Share on other sites More sharing options...

R11CH Posted February 4, 2018 Report Share Posted February 4, 2018 Definitely stick with genuine items. The few aftermarket items i fitted have now been replaced with genuine Bmw items from my local dealer as they failed in one way or another.

Roach Posted February 4, 2018 Author Report Share Posted February 4, 2018 Yeah for sure, lesson learned, I just hope it fixes the problem. Took it for a test run earlier, it gets to around 58-60 degrees, quarter way on the gauge and no more. Quote Link to comment Share on other sites More sharing options...
Roach Posted February 7, 2018 Author Report Share Posted February 7, 2018 Well after a nightmare with a flat battery, now fitted with a new one. Reading 12.2 ignition on and 14.1 ish when running, I can assume the alternator is healthy and charging the new battery? New genuine stats fitted too, Car needle now sits at 12 o’clock, and reading 88/89 degrees.. So I think, my nightmare of an introduction to bmw’s is over for now... I hope! Supposed to be driving to Scotland from oxford on Monday... best go give it a really good run. Quote Link to comment Share on other sites More sharing options...
Roach Posted February 8, 2018 Author Report Share Posted February 8, 2018 Oh and just in case someone was reading this with the same problem, it was the egr stat that was the issue, I’m glad I did both, but the engine stat that was on there was working perfectly. For ease, take the egr stat off first and see if you can blow through it.... if you can, it’s stuck open... I should have done this first. :/ Check your new egr stat by blowing too, you should be able to pass a little air, but not loads. Quote Link to comment Share on other sites More sharing options...
rasa Posted February 8, 2018 Report Share Posted February 8, 2018 great,,its deffo one of the items that only genuine will do. Quote Link to comment Share on other sites More sharing options...
Roach Posted February 8, 2018 Author Report Share Posted February 8, 2018 Indeed. Oh and my battery had got low again upon returning to the car today, with a brand new battery fitted.... thought the worst, but it seems I should pay more attention to my interior light.... I had a certain 4 year old helper the other day who I specifically asked not to touch anything inside the car..... how did I not notice it on?? :/ Quote Link to comment Share on other sites More sharing options...
