Hi All,
So I was happy the last week or so with no Trans fault, Top working, but today it came back.
It started this morning and then I got the restricted perfomance and some bucking. shut it off into neutral and restarted and good for a few miles then all over.
I had the Misfire codes and P1746 prior but now I have these.
P0301,had
1313, had here and there
1316, new
1733,,new
1758,,new
1384,,new
1747,,new
No 1746 today
so since this all happened today Im thinking thats why I got the circuit codes and etc... I never had them before, I had pulled the relays a few weeks ago and cleaned ,moved around, that took the Trans fault away,but this all started today.. Prev when I had trans fault it was in 4th gear and once up and running was fine, today it was in a low gear and if i tried to go faster it would buck, I would shut off and all fine for a little .engine light on course..
Prior to purchase it had sat a year or so, was a FLA car, Clean under, good body...Had Trans fault so cheap buy, Had it running pretty good, cylinder one has been constant issue , taking to a local JAG guru here tomorrow, see what he finds and hopefully Ill be able to DIY most of it, but any insight will help...I did not clear codes so he can see them all.??

Those codes could easily be caused by a weak battery. Before you take it to a shop replace the battery, erase the codes and see if they come back.

 

RJ237, the battery is showing fine, even had it tested for load...Like I said I was driving around last 2 weeks and yesterday it all started....

How old is the battery?

 

Be sure about the battery as the pain/costs of chasing what else it might be could be scary.

When loads of faults occur so suddenly you're looking for a common cause. If not battery, look up all the code meanings and study workshop manual etc trying to figure that common cause.

 

Hot vs COLD weather?
I know with some air leaks with the warmer weather they tend to tighten up,I have a 530i all summer the CEL is off, this week it came on, same as last year..No issues driving, engine smooth runs great. it seems like this also. could it be that a relay or plug is the answer?? As I said before, when I first got the car, I was messing with the passenger engine side relays and fuses and it was fine for a few weeks...
I checked the battery today. 12.45 went to 11 when starting. almost 14 when running..Hate to take to a Shop and find out its as simple as a relay or loose connection although I have checked and used electrical spray..
