You are right about this there are water trays at the back of the engine and they split and drip water on injectors 5 and 6 , I looked at mine just this week and the drivers one is split and will be letting water in , until you touch them they look fine but they are just sitting there and wobble when touched .This in mine the piece with the build date on it , looks fine but its actually broken in 2 .The centre one is the most critical and they get brittle with age.20220319_114848[1].jpg

My X6 broke down once and basically it was the water trays had split resulting in killing injector 5 and 6, although after leaving the car for 5 minutes it would reset itself , start and get about 2 miles and stop again, took me about an hour to get home....not to bad a job to change them and then of course sort out the trays.

Id say you are one one many Marti , I have heard they can corrode into the head and be a right pain to remove , Have seen the state of some that came out on utube and you need a slidehammer to attach to them to give a direct pull so then won't come out . I'm keen to get my tray replaced before any bother starts as it can't be broke too long as I have it off every few months to clear that annoying drain below the master cylinder that keep blocking

lezmtaylor I hope we can still be well enough to change plugs at your age fair play but 30 hours I take it there were issues

Hi Leslie,
With lpg there is so much more to dismantle with pipework, electrics etc. Of course with such a long plug change interval, I forgot what had to be removed, dismantled etc. Being retired and having time on my hands there was no reason to rush it, just enjoy !!!!!

Sounds like a busy week Lez

Well tried to be cheap and buy a secondhand partition tray , asked the seller very clearly was it cracked , pics were supplied and well its arrived and is for the bin big split down the part that usually splits but to be fair not obvious unless you know what you are looking for going to buy new from Bmw lesson learned Still cheaper than 2 new injectors

what with a new rad and new water pump already it's been one of those months

Are they expensive to buy from bmw?

Update yes the plastic shields are expensive lol 95 plus vat each ...for a piece of badly designed plastic ...ouch realoem way out on price this time said 60 dollars usually its the same value in pounds I find

Hi Leslie,
Just a thought,(bet you have already ) can you not repair the plastic with a soldering iron that will melt and stick back together, or rivet / bolt a patch over split, or fibre glass a patch ?
Just my twopenny worth.
You have a spare,unless thrown away to play with.

Lez I have already ordered now but yes when I heard the price make do and mend did come into my thoughts. Luckily I only need the one and if the others fall apart I will certainly be trying that type of fix in the future. The secondhand one I got is still in one piece so would have been ideal to repair. Thanks for the thoughts at this rate 2 new injectors might be cheaper
I have seen Chinese ones for sale but they look slightly different and like a few of these copies are all for LHD vehicles, the wiper motor is on the opposite side and the moulding is different I think to slip under it.while looking for a window switch cover before I found the cheap copies were all LHD and a mirror image of what was needed.

I bought these trays from evil Bay a while back for my x6 and they were a pretty good fit. Original had been broken by bmw while doing servicing work although as usual that was denied.

If my 02 sensor and exhaust temp sensor still show as current faults should my eml be on all the time? Thanks

MOD Edit - changed to sentence case from all CAPS…

Hi Eminem, please I’m Alessandro. I kindly wanted to ask you how you solved the 4B82, 40D4, 4C9F, 4C9E error code problem on your X5 E70 40D? I also have the same problem on my X5. I wait for your reply! Thank you.

You may be waiting a while as the user hasn’t been seen since April 2022.

I had a a code for the 02 sensor with no eml light on....only reason I plugged it in was I had a bit of smoke coming from the rear so changed it out and no more smoke.....
