Leon 184d Starting Issue

Hi All,

New to the forum I just wanted to share my experiences with the Main Stealer in my area as well as consult the gurus among you as to where to look for this issue. I have a 184 Diesel Leon 2014 plate, bought used back in November 16 went fine until around Feb 17 when I started to notice an intermittent starting fault. It would turn over and over 4-5 seconds then start but running fine no miss firing no loss of power etc.
During that turning over it will not fire on a single cylinder closest I can describe it would be getting no fuel, I have some footage of it I will attempt to scrape the audio from the video and post it here.
This happened maybe 1-2 times a month and it was cold so acceptable in my eyes anyway it has progressively got worse and worse 10 seconds turning over in 30Deg C heat something is definitely wrong! I took it into my Local Seat representative dealer and they have now had the car on and off for 8 weeks or more. They first seen the car in April and it's in for a further two weeks currently so this gives you an idea of the time scale involved here.
On the odd occasion, it has caught on a couple of cylinders but not enough to start i.e. rough starting as opposed to the usual tuning over and over not catching a single cylinder.
Diagnostics - There are none the car is throwing no faults Seat have confirmed it as has a friend with a Snap-On Diagnostics scanner so we have no hope on the ECU throwing a fault it seems.
Now onto the garage I have a dash camera and can I just say please everyone buy one!!! Caught the garage doing all sorts
1) Undertaking on dual carriageways
2) Replacing my rear light cluster due to water ingress turned up to collect and the newly fitted light unit is literally hanging out of the car!!!
3) Claimed the car was started once if not twice a day to reproduce the intermittent fault and I have footage of it being left out front for 5 working days out of the 7 it was in the garage.
4) One day they started it 20 times (not according to my dash camera you didn’t start it once)
5) Two chips to the paint work one when fitting the light another on the end of my drivers door clearly opened into a wall or rough surface.
6) Next up we have some potential fraud a fuel filter I paid for the part; fitting they did free under warranty, so then I have a convo with the senior mechanic and a trainee on the camera slagging me off calling me an F*ing anorak and all sorts (never met the guys) to then:
(senior) Has it had a fuel filter?
(Trainee) Yes brad fitted it.
(senior) Hmm but do you think he actually fitted it.

Sorry wait a minute a senior engineer just suggested a part I have paid for may not have been fitted on my car why on earth would he say something like that unless they are working that way on a daily basis.

Anyway, I have since recorded all sorts of funny noises coming from the fuel tanks hissing (sounded like I popped a tyre) loud buzzing with a full tank of fuel, weird sucking noises also got video of these I will attempt to attach those also. With this evidence Seat reportedly replaced the fuel tank but it's still making the sucking noises and the hissing was intermittent anyway.
As you can see I have had a hard time of it my car ran out of warranty in July they have kindly extended it for the starting fault personally I think they had little choice but still nice of them to do so.
I will release the name of the garage eventually so others in my area can avoid it like the plague.

Adding link to audio as promised (Cannot put a proper link in can someone please reply with the full link just needs https : // infront of it:

I had mine back in a couple weeks ago with similar starting issues and they had a software update available which was applied and it's been behaving itself since so I'm hoping it's resolved it. Might be worth an ask if it's up to date or not

Indeed I will post it once things have calmed down a bit! Thank you I did search before posting and found this one but indicated it seemed to be in cold weather so I thought it different to mine. Although sound like in general they are not starting great!

Thanks for replying, It does indeed have a full Seat Service History, and I am using BP Ultimate Diesel.

Perhaps just try one full tank of Shell Vpower Nitro Plus Diesel and see if these 'gremlins' go away?

Thanks, I will give that a try once I get the car back ATM Seat are accepting it's an issue so much so that they are not willing to give mine back to me until they think it's resolved even suggested I go down every morning / evening and start it with them until I am happy, no doubt due to the overwhelming negligence I have them for currently.

Without actually naming the dealer can you say which area you live?I'm worried it could be my local dealer!

Anyone got any comment on the link to the audio I provided does it sound familiar to what you guys were experiencing or worse etc? just wondering if I have the car back and tell the garage not to bother as they are looking for something that is not there! Only problem is I have diesel lawn mowers that can start faster than my car without any pre heat...

Having listened to the sound track - that's exactly like my old 184.
As Stu_m said - I posted on the other link.
Mine was the camshaft angle sensor.Never showed on diagnostics but Once changed it never happened again. Maybe worth mentioning to the stealers :)

Sorry - now having listened to both !! Doh !!
The first sound is the normal fuel pump purge on ignition. This spins up the electric pump in the tank to get to the correct fuel rail pressure.
If there was a fuel problem - this 'whine' sound would run for much longer,but yours sounds ok.
Therefore my guess would be a sensor failing- the engine cant 'find' which cylinder order to fire up first - so the injectors wont release fuel until it knows its position in degrees - found by looking for the camshaft position sensor so it knows which valves are open or closed and which cylinder to squirt into first !
Thats my theory !
Anyway hope you get it sorted ! :)

I have the same thing with my fr184-seems to take a bit longer to start from cold.I also had it on my fr170 and that was the cam sensor.

Thanks for taking the time to listen and replying! I have told them since day one it could be the CPS plus it is cheap and relatively easy to replace worst case put it back in the box and swap back to my old one.

Had a LR Defender with a defective starter motor that was drawing to much current this interfered with the unshielded sensor wire for the CPS and low and behold intermittent starting issues.

Thanks,
Luke
