Hi,

I own a panda cross multijet and in June (after 6 months or so) the warning light for the preheating glow plugs lit up. So I went to a garage, they replaced the plugs and updated the firmware. They said it was a known issue and it should be resolved by the new firmware. However, after two months only the warning light flashed up again. So it's time to return to the garage..

Is anyone experiencing the same problem, or do I own a lemon car?

I have had the same issue (on 4x4 MJ, not Cross). Warning light came on to show a glow plug failed in February, replaced under warranty, and another in June. No issues since. I am sceptical when dealers talk about things being fixed by 'software/firmware updates' - I don't believe they exist!

The illuminated "coil" shaped warning light isn't just a warning light for the glowplugs on modern diesels, it's used as a fuel system warning light, similar to the "Check Engine" light, but for fuel/intake issues.

Basically any fuel system fault can cause this to light up or flash.
It's the bringer of dread for may diesel owners as it's often an expensive fault, sorry to say.
Common causes are
Low rail pressure, usual caused by excessive injector leak off (light flashes or lights up on hard acceleration) or clogged/water in fuel filters.
Turbo wastegate issues, jammed up and an over boost detected. (again hard acceleration)
EGR or emissions issues (DPFs??)

I doubt the plugs themselves are at fault in either case.

Thanks Goudrons for your explanation! Makes me worry a bit though. I'll see what the garage says and does :/

If I had one , there's one or two other things they have to fix anyway, something with the clutch lever and some foil to be fixed.
