The cold weather has confirmed that I need new glow plugs. My 2010 chassis number AH, should have LR001302 glow plugs. From chassis number BH the part number is LR022300. I have read all the threads on glow plugs that I can find. I am under the impression that the AH glow plugs are 11volts and the BH glow plugs are 5 volts. Can anyone confirm this for me before I place my order? I am thinking of buying these

Which are rated at 11 volts.
Thanks in advance

I've never heard of 5 Volt glow plugs. The supply current would be enormous, requiring thick cables and powerful 5 Volt drive circuits. Hyundai Ioniq 5 Ultimate. The family car.

2006 Tonga Green i6 HSE. Gone.

Here is a link to a glow plug suitable for a BH chassis number

Which is rated at 5 volts.

I am no expert on this subject, but came across the discrepancy whilst browsing for replacement parts. Some vendors ( advanced factors for example ) list one type of glow plug fitting both AH and BH models, others specify two different glow plugs, hence my confusion.

I have seen quite a few different brand glow plugs rated at 5v, but most seem to be for the BH chassis number and the 11v for the AH chassis number. It seems a lot of members have suffered glow plug failure, myself included. I am wondering if the change in part number and voltage is an attempt by JLR to resolve the issue.
The dimensions of the two different parts seem identical, just the voltage is different. I am thinking that the parts are not interchangeable, but perhaps someone who is better informed can correct me and advise differently. Do the lower voltage plugs have more longevity? Are repeated failures due to members fitting the wrong voltage parts? Seems worth clarifying.....

I am sure that this has been covered on here already. Certainly up to 2009 11 volt plugs were used and were fed from a relay. At some point after 2009 5 volt plugs were used and were fed from a glow plug control unit under the scuttle. I only found this after having replaced my 11 volt units with 5 volt ones and had to do the job again. Silver 2009 HSE

I don't want to have to do the job again. Paul from advanced factors has offered to look up the vin to offer the correct part. My car was manufactured on 11/01/2010 according to the VIN number. I will post his response

Paul from advanced factors has replied promptly ( thank you ), to say that my AH chassis number car does indeed use the 11v glow plugs.
I shall be ordering a set along with the intake manifold gasket, and getting the job done over the next week or so. I don't think that there will be any startling insights when I do the job, as both ways of doing it are pretty well covered in other threads, but will update if I find anything out of the ordinary.
Thanks to all who replied
