Hi There,

I've been struggling for a fortnight to start my 308 1.6 HDi.

Changed the Fuel Filter - followed the Haynes book of lies and appear to have air in the system.

I have read, and read, and read, and read about how to resolve this and do not seem to be able to get the priming bulb to firm-up - that said, I don't know how firm, firm is?

I can get fuel flowing through the priming bulb, I can hear it. I cannot see air bubbles as I don't seem to have any clear pipe anywhere?

I'm guessing there's a chance that the priming bulb is shot, as it is 11 years old, so my plan is to use a separate pump and piping connected at the fuel filter, so I can see bubbles and also so that I don't need to lean in to the engine bay for quite so long, as to be honest my arms, wrists, legs and back cannot take much more.

Can anyone tell me what size quick connect adapters I need to order? I cannot fathom it out. The fuel filter is a Delphi HDF939. From what I can see, these are listed as 10mm on anything I can find related to the filter. Quick connect adaptors appear to have two sizes listed, I've just had to return ones that were listed as 10mm as they're not correct, (11.8mm x 10mm). I had guessed that the 10mm, referred to the 10mm, however that doesn't appear to be so, as they do not fit whatsoever and have been unable to find any guidance anywhere on this type of adapter.

Cannot find them listed on ECP (don't know if they have another name?) and really don't want to part with anything from £90-£150 on a full on priming kit for a job I'll rarely do again - in fact, after this, will likely never tackle again. Cambelt is easier than fuel filter!

Had a leaky injector last year which was repaired by a diesel specialist. When I picked it up, they advised that the best way to avoid an issues was to ensure that the fuel filter was replaced when servicing. EGR was sticking had to take off all the gubbins to get at that to clean it - which I cleaned and subsequently replaced as it was beyond serviceable.

Figured changing the air filter and fuel filter at the same time made sense.

Figuring and knowing clearly being two different things.

Yes, other than running a little low on power as the EGR was sticking. Kicking myself now, as hadn't anticipated this. If I had, I wouldn't have done both at the same time.

First time the car has ever not started.

Yeah, tried these. Have pumped that thing so much that I physically couldn't do any more the day I changed the filter. After several hours had the missus try turning the engine while I was pumping away at the prime pump. Battery has been off a couple of times to charge it up again.

Can't for the life of me find any documentation anywhere that details the sizes of the connectors. Seem to be known as SAE J2044.

It takes quite a few presses to firm up the bulb, what you are doing is filling the new filter with fuel and it holds maybe half a litre so keep pressing and it should eventually firm up.

How many days do I have to do this for? I've spent literally hours and hours pumping away on this thing and it hasn't firmed up. Hence the thought that maybe the bulb is passed it's best?

I would prime the filter with diesel before fitting too - however that ship sailed a fortnight ago. I cannot imaging that there isn't enough fuel in the filter now, like I say, if I had to total how many hours I have spent pumping away at that little pump, I'd estimate it at between 6 and 7 hours.

As you can see (on not see) in that video, there is no clear pipe to check for bubbles.

Sorry to hear that...but perhaps im old fasioned but where is the air going that's in the filter? If I was to come and help you (but your too far away ..sorry) I would remove the filter...press the bulb to see If any fuel came out of the pipe near the filter...prime the filter...refit...press bulb a few times...I've done this a few time on the wifes 308 when she had it...

Maybe you have lost the imobiliser key codes by having the battery disconnected for too long?, if you disconnected it that is. I used to do mine with the battery in situ.

I'd thought the same - where is the air going, but figure there must be a return to the tank so the air is probably going there?

I also wondered that about the imobiliser code as it's something I've seen others online have struggled with too, how would I know? The key unlocks and locks the car using the remote and I have tried the BSI reset just incase. What symptoms would I see if it was the immobiliser? Would it crank?

Hmm... No beep, pretty sure it did though - car is now in economy mode, so not sure if it would beep now? I'll take the battery off and charge it and test again tomorrow.

Not sure charging the battery will help with economy mode, I don't think that will go away until the engine has been started. I personally wouldn't leave the battery disconnected even for charging as the imobiliser codes can be easily lost, then you will have to reprogram in the code using Planet, that is assuming you do have the code.

Also, don't have the codes so may end up just scrapping it as really getting tired of dealing with it. It really is an odd design. Same with disconnecting and reconnecting the battery - it's a convoluted procedure, made all the more challenging when working in poor weather - having to keep a window open so you can reconnect a battery is almost as nuts as having a car that cannot have the battery disconnected.
