Dirty Fuel Tank?

[mouks]

I'm no petrol head and need some advise. Can anyone tell me what the symptoms off a dirty fuel tank are. I'm currently fixing up a E36 318i BMW Dolphin Shape. Car idles fine but has trouble accelerating in first gear, slight jerks effect like it not getting petrol/power or something. Once it reaches optimal speed the car runs fine. I need a second opinion and don't want to be conned out of my money

Doubt its that.
It might be your fuel pump or MAF or even a dirty fuel filter that needs to be replaced.
Suggest you take it to a reputable BMW workshop for proper diagnostics.

Yeah, most likely the MAF or some other sensor. Also check the throttle body that the butterfly flap is not stuck. And stay away from BMW dealerships, they will rip you a new one.

There are probably more symptoms, but from my experience a dirty fuel tank will exhibit stuttering on acceleration when the tank nears empty.

yeah, meant to say reputable Independant BMW workshop, not the dealers themselves.
Its probably the MAF, but at +-R2700 a pop its best to get a proper diagnosis of the problem first.

Yeah those things are goddamn expensive :wtf: I paid R3k5 for mine.

Well realistically you should replace the MAF and most other sensors at around 160k as part of preventative maintenance...
Im just glad all of mine are still fine...

When driving about 90 or 100kmph put your car into 1st & let the clutch out. That should clear it up.

Get the OBD plugged into by a BMW workshop (stealership or other) get a print out of the fault codes and work your way through those first.

Also check all vacuum hoses for leaks

You can get MAF cleaner from some part shops although they are normally reluctant to sell it to the public and will try sell you a new sensor at a retarded price.

Take it to Frank's Motors, Queens Park Road, Salt River. They fixed my pa's 318i after Auric Auto had quoted R9000 for a whole list of things. In the end he paid R1250 and only 1/3 of the items listed needed doing

MAF cleaner will not work if the MAF itself is faulty. I've used pure alcohol on mine for my previous car, and it worked.

You have to be very careful when using MAF cleaner.

 

[Sinbad]

Symptoms don't sound like fuel or Maf related... Does it also jerk/hesitate in higher gears?

True but it's a lot cheaper than replacing the sensor so it's worth a try.

That's why you should read the instructions
