As the title suggests, there were worrying noises coming from the engine bay when the turbo kicked in. It’s also worth mentioning that every time this happened I had an ungodly amount of thick smoke coming out the exhaust.

Good news: it’s not the timing chain.

Solution: One of the m6 nuts that hold the injectors down had come loose. Upon retightening I found that too much torque caused the nut to jump back up the bolt due to a bad thread on the bolt. I fixed the issue by tightening it up to “something that felt about right” without causing a skip, then adding another bolt on top to lock it in place.

Only discovered this after changing:
Fuel pump
Fuel filter
Fuel pressure sensor
Injector seals
Boost solenoid valve
Oil
Oil filter
Air filter
Air temp sensor (recommend for nicer start ups)
+++
Injectors removed and cleaned
Intercooler removed and flushed
Intake manifold removed and cleaned
Intercooler hoses removed and checked over for leaks…

Safe to say she’s had a good bit of TLC this month, but as it’s a well serviced vehicle I would have been quite content to have noticed the slipping nut prior to all of the other DIY 😅.

I hope this thread can help someone else out who may or may not be about ready to “get the damn thing fixed and just bloody sell it”. Because now that she is back on form i’m back to being tremendously charmed by what the Freelander 1 has to offer!

Best wishes all.

A £35 LP pump from ebay? I'm keen to see how this goes. Would be great if you could keep us updated on reliability/ pump life. I bought a Peirburg a while ago as I always like to buy "good" parts, but it's mega noisy and makes me feel like it's going to let go any time soon.
 
Here is a link to the fuel pump that I purchased, as requested. It’s only been a week but so far so good!

 
So as the new title suggests, this issue has come back strong. Given the temperamental nature of it I am going to have a crack at changing the turbo boost solenoid. In hindsight, I think this issue began after it had a bath whilst doing some serious off roading. Won’t be doing that in my work horse again… Fingers crossed, will update in a few days.

Ah hope it gets sorted, water causes so many issues it's not fun. May have to get a new work horse and keep this one for play time.
 
I haven’t got the software nor “a guy” for that at the moment, unfortunately! Would you have any suggestions?
Well it looks like you have the FL1 bug, so you really would benefit from your diagnostic tool if you intend on keeping it and doing some fixing. Use it a couple of times and you’ll have recovered the cost.

Personally, I tried the off-the-shelf readers at first, like icarsoft, which are a bit hit and miss with the data they can ‘see’. Ultimately, I got the Pscan, and would say that it’s by far the best I’ve seen in terms of data access for the FL1. Philip (the guy who makes them) is on here, but this is the web site…


 
Update:

Whilst waiting for my new solenoid to arrive I decided to test the car running on 3 injectors.

With injector 1 (far left) unplugged, the car revs through the range without smoke nor splutter.

With any other combo of injectors plugged in, the car won’t rev past 2k.

Does this point to injector 1 being a leaky mcSneaky? Stay tuned to find out

You SOB! 😃 I've been struggling to find out why mine has been smokey from doing the injectors (smoke didn't start until a week or so after) and it turns out all of the nuts could turn another 1/4 - 1/2 turn! Now no more smoke! Didn't even think of checking the injectors as in my head they were good and tight.

Thanks for this, would've been pulling my hair out (not that I've got any to pull 😃) for ages trying to figure this out!

Awesome stuff! Glad my hours of effing and blinding have helped you out 😄 back to telling all my mates how the freelander 1 is an underrated and overlooked gem of a vehicle, hope you are too 😂
