Jerky car, struggles on pull away, high fuel consumption

[ChrisBrand]

All symptoms of two things I found wrong on my car.

Crankshaft sensor and MAF sensor needs replacing.

Just thought I would post this as alot of people post threads with these symptoms.

Now if they would just use the forum search function...

 

[Loom]

Did you get specific codes for those sensors?

 

[ChrisBrand]

I did not check the codes but they are there. WIll pull them and let you knowi

 

[Twinz]

Codes are a good place to start :thumbs:

Does it suffer more in this heat than it does on a cooler day?

 

[ChrisBrand]

Yes it does suffer more the hotter it is.

The details I got:

DME -> 53/B8 - Signal, crankshaft sensor
08/B2 - Signal, air-mass flow sensor

It seems the codes are expressed in DTC(hex)/PARAM(hex) format and not the conventional P-code

My 330i is horrible to drive in this hot weather and pinging like a mofo!! Today it is a fair bit cooler and while it is still a bit of a handful in terms of being jerky, the pinging is less.

Same here, especially between shifts and pulling from a hill.

As a side note I phoned around for prices on the abovementioned parts:

Crankshaft sensor:
G-drive R450.00
Goldwagen R975.00
BMW R1700.00

MAF Sensor:
Diesel Electric R1200.00
G-drive R1200.00
BMW (Didn't even bother, last time I heard it was something like R5000.00!!!)

 

[Loom]

What brand sensors did you use?

 

[Henry330i]

If its for a 330i oem is Siemens. I've phoned diesel electric and they don't seem to stock them. Also look at partsonline.co.za. I'm also looking for a MAF. Incomex don't know when they'll get stock again and I'm worried about some of the brands out there. On the international sites quite a alot of guys had issues with the no name stuff.

The E90 MAF is VDO - will price it from those guys, there's also a local place that sells MAF and other sensors, they often advertise on Gumtree. Will have to search for them again...

 

[ChrisBrand]

Siemens is OEM. Think Diesel Electirc stock Bosch. Not sure about Goldwagen. G-drive told me their MAF sensor is OEM-like. Thus, its not Siemens or Bosch.

I have bought a pirated MAF sensor for R700 before. Lasted all of 4 months.

On BidorBuy there are Crankshaft sensors for R450. Not sure what brand otherwise I would have bought it long time ago.

@Loom. All sensors were OEM. Looking at replacing them now. Crankshaft and Camshaft sensors have never been replaced. MAF replaced twice before.

Found the site: http://airflowmeters4cars.co.za/

Have you tried Mr. Turbo, they brag that they have MAF sensors for almost any car?

Thanks! Can't seem to get onto their site for the moment, will try again - might be down temporarily...

Feel free to swing by and try some MAF cleaner if you want. Sometimes it's just dirty. Especially if you use an oiled filter.

 

[Philip Foglar]

Have cleaned the MAF a few times with LiquiMoly MAF cleaner - no difference. Plus, I am using an OEM non-oiled filter. I must just test a good MAF on my car to see if there is any difference...

 

[ChrisBrand]

Thanks Gareth! Will maybe swing by sometime next week to catch up.
