e46 320d fl rail pressure sensor

[Allym22]

Hi

I have a 2003 e46 320d and currently on 234000kms. Car runs great :rollsmile:! I need to replace my rail pressure sensor. Anyone out in Cape Town with an idea of where I can get one at the best possible price?

Dude what makes you think it is the rail pressure sensor? Mate had a cab also throw rail pressure codes, turned out his fuel pump in the tank was on its way out.

As above, rail pressure faults isn't only the sensor hey. In fact, I'd rather say it's your pump or blocked fuel filter. Replace those first, especially if the fault only comes up under high engine loads.

If your rail sensor is faulty, the car would probably not start in the first place.

Thanks for your response. I have an occasional misfire. Have cleaned out the MAF sensor with MAF sensor cleaner, egr valve as welll. The misfire is occasional. I have an automatic and the misfire occurs in P as well as N, R and D. Car still runs smooth and fuel consumption on display averages around 4.2-4.4l/100km.

Misfire is more frequent under load from the aircon.

I have changed the fuel filter. Car starts fine without any hassle. Have cleaned out the MAF sensor with MAF sensor cleaner, egr valve as welll. The misfire is occasional. I have an automatic and the misfire occurs in P as well as N, R and D. Car still runs smooth and fuel consumption on display averages around 4.2-4.4l/100km so no fueling issues.

Misfire is more frequent under lroad though. I will have a look at the pump again. Last time i listened both pumps were operating.

Thanks again

Yeah bud, pump may be operating but on its way out hey. What is the exact error message you getting relating to the rail pressure sensor? And check if you only get this error under load. That will help us narrow the issue down.

Hi guys... Turned out to be a breaking contact on one of the injector plug wires. It was thinning out quite bad. Soldering the contact seems to have done the trick....:clapper: I'm back on the smooth path again with thankfully a cheap and quick fix.

BMW dies not have the connector plugs in stock and will have to order from Germany at just under R50 each incl vat. Will replace it once it arives in two to three weeks. :ty: thnx for all the responses .
