So I had been out running errands today. Outside temps around 34 degrees. Was at a red light and then it turned green and I noticed the acceleration was a bit slower than normal. Looked at gauges and temp gauge was in the red and the little red dot light was illuminated. No flash, no beeping. Pulled into gas station, opened hood. No steam, no leaks. I didnt check the expansion tank level (dooh!). I let it sit for about 20 minutes. Turned it back on and drive less than a mile to my local BMW dealer. Temp stayed in the 12 o’clock position for that short trip. Don’t know if it was still in limp mode or not since I was keeping my RPMs low.
Lucky for me I was so close to my dealer, and I was already scheduled for an appointment with them for tomorrow to address the open PCV recall.
Questions are since I am do new to the e85 platform :
- Does the red light flash when it is way hotter?
- Is there an audible alert at some point?
- Is the limited acceleration part of the ECU limp mode?
- I really don’t know how long it was in the red, but didn’t notice any difference in engine behavior until I took off from the stoplight… what are the chances of damage to the engine?
I have replaced the similar pump on my N20 based engines in the past (not hard at all) so not looking forward to big $ paid to the dealership knowing i can get the parts so much cheaper and do it myself… but it is already there so.
Anyway, wanted to pick your expert brains on the topic.
I plan to have them replace the pump, thermostat assembly, and mount an aluminum coolant flange fitting that I already have (part is by Rein and eliminates the plastic OEM part that is prone to failure).
