Bmw troubles

Asked by Feb 21, 2016 at 06:02 PM about the 2003 BMW 5 Series 525i

Question type: Maintenance & Repair

I just got my car out the shop. Spent about 700
dollars on a fuel pump and a new MAF. Two days
after getting it back from the shop. I went to start it
up, and had a very rough idle. Little to no power
when accelerating. After looking stuff up and talking
to a mechanic who fixed my car, I unplugged my
MAF and it started running fine. I plugged it back in
and it ran fine when I started it up. Now today I had
the same problem and had to unplug the MAF then
plug it back in to get it to move.  Thinking maybe a
vacume leak even though the shop said they
checked. Any ideas?

Unplugging the MAF forces the ECU to run on default set values. Is the check engine light on? Time to find an independent BMW mechanic.

Best Answer

@tom yes the check engine light is on. I had brought it to a place called bimmerwerks.

Scan for the codes and post them back here. We can't help before then. Surprised they couldn't fix it for you.

@tom just got a obd meter P1351 P1349 P1353 P0300 P0102 (which may be because I unplugged my MAF to drive my car but I plugged it in right before I scanned for codes)
