Hi All,
The orange fuel system failure light on my 50k mile Vitara seems to have developed a mind of its own.

It will come on after about half an hour of driving , when you stop it goes off and will come on again in another 20 to 30 mins.

It did give a fault code on our local independent garages system, indicating a throttle position sensor fault. this was changed and the codes cleared. No change. Fuel filter changed, no impact and it does not show a fault code on my OBDII scanner which works fine with my other cars.

Any ideas please or is this one for a main dealer??

sorry can't help. Can't cope with ecu prefer old school mechanics

Cheers Robbie,
Much the same myself unfortunately.

First of all welcome. Another newer generation Grand Vitara on theboard.

2013 might still be covers under a Suzuki warantee? Sounds like you have done all the things I have suggested by way of fuel filter. Did you reset the codes / clear the error message when you did that?

Sorry, can't help much more. Stay with us on this forum, and see if you can get any clues from a Renault forum as that's a Renault diesel Suzuki fitted.

Ahh, rightho - of course it is. Thanks for that. Mil light has come on today so I might have a code now.

Post up the code, I'll see if my resources tells us what to look at. Do you notice any difference in engine note / pulling power or anything else? Sometimes cars give too much information.... but I'm the sort who'd hate a little light warning about something no matter how trivial.

Been doing a bit of reading and apparently it could be to do with the Diesel Particulate filter.. a clogged air filter, an issue with the EGR valve, or even the pipe between the turbo and intercooler de-laminating on the inside.
Don't have a GV or even a myself but might be worth checking those things out too

Same fault , fuel system warning light on after about half an hour of running. Goes off when stopped on again later etc. Sometimes throws up a throttle position fault code. If you clear that it goes away.
Is it a defective EGR? Time to replace? If so any ideas on how i can obtain the part number. I notice ebay sellers have EGR valves for about £80.00 rather than the £304 at Euro car parts.

I've also got a similar issue on my 1.9 ddis 2011 gv but the 'water in fuel' light is now staying on constantly. I've drained the filter but nothing fixes it. No codes that I can see. I'm assuming it's the sensor but been quoted £160 by suzuki for that. Its not doing many miles because of lockdown. Did you manage to get to the bottom of the fault? I can't decide if I care enough about it to fix it! Any thoughts? Cheers

I used to have an old Peugeot 405 diesel and the water in fuel light used to come and go all the time, I got fed up with trying to sort out why ands just left it in the end
