Texas Heat and Coils

[btmed]

60 plus days of 102 to 107 degree heat here in texas. replaced coils and plugs just last summer, meyles, for my 2001 x5 3.0 120,000. was running rough this week and decided to let moritz diagnose. They found 1 coil bad and replaced. On the way home punched it to get on highway and the car starts shuttering just like it did before. pull over, restart the car and everything fine. Same thing happened again this am when wife went to work. I would think if it was another coil it would not reset. I noticed on the repair bill they mention possible faulty inlet and exhaust cam sensors but they didnt replace. Those were also replaced last summer but not oem. Would it be more apt to be sensors instead of coils? BTW moritz wants me to bring it back but will charge me another $130 diag. fee. Anyone else having coil probs due to excessive Texas heat this summer?

I'm in Carrollton and have not had problems with coils/sensors. I did just lose the water pump though. Keeping fingers crossed to last out the hot weather without any more issues.

If your aftermarket sensors and coils are all failing after 12 months, might be an idea to go with OE BMW.

Your right should have gone with oem. Those that I bought were bwd brand at oriellys, $200 instead of $250 at BMW. Not that much of a savings but on that note they have a lifetime warranty. So off I go back to oriellys a d they give me 2 new ones. No charge. Put em in and the cars running like a champ. Another sidebar moritz wanted $348 to replace intake side and $288 for exhaust side. It took me maybe 20 minutes to replace them both! F#*¥ers!

still continues, had to go to a wedding in dallas with the wife last night and the same problem came back. about 20 minutes into the ride the 5 starts running rough again. Pull over stop then restart and it goes away. Same thing on the way home after about the same mileage. Read the codes this morning, P1345 misfire cyl 2 with fuel cutoff, P0505 engine speed not inexpected range, vacumn leak, dirty throttle body, iac motor defective take your pick. Happens when im doing bout 75 or 80 on highway never in town. Cylinder 2 is the one moritz put the new coil in. Did notice intake cam sensor slid right in when i installed where the exhaust side was very tight. The reception was at the State Hall in fair park last night. If you know dallas that is not the best area but a beautiful building. I told the wife not to lock the car when we got there, maybe somebody would steal it! No luck. Guess i will replace the oil housing gasket tomorrow then the oem intake cam sensor on tuesday.
