Okay, here goes.

I own a 2.2l CDTI Honda FRV, it has 55k on the clock and has F6HAD's stage one, with EGR remap on it.

Here is a video of the fault I currently have

A week ago on Monday I was caught out by a tidal road while on holiday in Devon, which saw me having to drive through about 150m of foot deep sea water. When we made it to the dry road the car juddered a little in first gear, but after a short time the car drove fine and we got home with no issues.

On the Tuesday the car started and ran absolutely fine with no symptoms.

On the Wednesday the car struggled to start. In the morning it seemed to labour, judder or misfire when starting up. Once started it ran just fine and we went out for the day. When we came to start it at around 5pm that same day it took several attempts and maybe 20 seconds to get started, with the same labouring, juddering or misfiring. Again, once it had started, it appeared to run just fine.

Since then the car has continued to run fine, however the start up is not what it once was, still seeming to labour/judder/misfire before starting. It may be my imagination, but the engine also seems to stop a little rougher than before.

I am concerned about myself or my wife getting stranded.

In an attempt to see what I could figure out I have done the following.

1.Looked at the air filter which shows no sign of water ingress.
2.Had the battery checked by Kwik Fit and that was found to be fine.
3.Started and stopped the engine a few dozen times. Whilst doing this the engine, on the odd few occasions, seemed to start and stop completely normally only for the fault to return soon after. Currently I cannot get the car to start normally no matter how many times I try.


Does anyone have any idea what my issue is?

Thanks in advance for any help.
 
Hi Barry,

is it possible some water has got into the fuse/relay box? perhaps some ingress into the fuel system somehow and caught by the fuel filter?

Take it on a good blast, and really open it up a bit, that might help.

Without diagnostics, it's difficult to know what's happened
 
Thanks for your input F6HAD. The car has done about 600 miles since the insident, do you still think a proper blast could help?


I've been having another look and tried the start up test as in my first video on a warm engine. It certainly seems easier to start, and occasionally feels normal again. See what you think, the difference is quite significant.

I have done another video after taking the car out for a "spirited" drive to get the engine hot. It seems to rule out the chance that this issue gets better when the engine has been run!
