1.6 N47 Glow Plugs - How to know which are correct ones?

[Grigsi]

Hello Guys, 

BACKGROUND:

After 3 years of being SORN, I am now trying to put my R56 Mini One D back on the road. 

It was running perfect when parked up, but now it is quite rough and will not rev above 2700rpm.

My OBD2 scanner cleared the engine light and detected and cleared a code for Mass Flow. 

But no other faults could be found. So I bought a Vlinker BM+ scan tool and downloaded BimmerLink and low behold, found another 12 codes that all cleared ok. 

However 2 codes now keep returning which say Glow Plugs 3 and 4 have failed. 

THE PROBLEM:

Every time I go to any car parts website and enter my Registration Number my car details are correctly found and I am offered a list of compatible glow plugs. 

However, some of these are 4.4 volts, some 5 volts, some 7 volts and even an 11 volt option. 

Most of them tend to be 4.4 volt plugs, but how do I know which ones are correct for my car please? 

🤔

Morning George

I use www.realoem.com it is a BMW online parts list Dealer level, put the last 7 digits of your Vin number into the search box it will bring up your model. Then search the engine electrical system section and get the correct part number. Then use google to find the best price don't dismiss your Dealer they often come up competitive.

A tip I have learnt the hard way if your changing Glow plugs on 1 series and X5's prepare first soak them in penetration fluid for a few days change all 4 and the controller (I have had to redo it on two separate occasions to change the control unit !!!

Thats your weekend taken care of 🤣

Good Luck

Thank you Dave, 

I replied last week, but do not know why it is not showing. I must have done something wrong lol 😂.

I used your link and I now know the N47 block in my R56 needs the 4.4v ones, which incidentally are rated for 6 minutes afterglow and are also able to assist with regenerating the DPF by boosting the gas temperature during regen.

Make sure you change the Controller as well as the Glow plugs and I am sure you will be fine.
