Yellow exclamation light

[magoo1]

Driving home this evening M1 and and A52 car driving lovely.

Stop to fill up and on restarting the yellow exclamation mark warning light is on.
The onboard diagnostics some about particulate filter,

Is it still safe to drive got a 25 mile trip tomorrow.

Thanks

A yellow triangle that lights up after filling up with diesel, in most cases points to FAP (Eolys) fluid that is running out.

What is the mileage of the car? Around 100.000 miles?

When mine came on (112,000 miles), it just had engine fault, repair needed. It didn't reduce speed or power output, but clearing the message on my big screen, cleared the yellow triangle until it was re started. There was no issue with driving mine until I could get it checked, and then a week later to get it booked in for a refill and reset.

Thanks, how did you clear the message ?

Mines a 2009 16hdi multi space.

I've got the horrible big screen in the centre console/dash, touched the close x and it cleared it until I restarted the engine. But it's only a short term solution.

Ta I don’t think I have that option.

Be nice to not have it when driving.

Into the garage soon

Just got car back from garage,

the only fault code they are getting is for the glow plugs which like a lot of garages are reluctant to touch,

Gave a me a specialist but wo week wait, says it ok to drive but keep urban to a minimum.

could be fro 400 to 900.

any thoughts?

That garage wanted you off the premises - give me £900, I'll change the glowplugs and have roughly £870 left over.

Does any message come on the centre display upon startup? Does it beep?

On start up the yellow triangle with a exclamation mark inside the triangle come on with a beep and stays on, the display says “risk of filter blocking”

The garage admitted they didn’t want to do the job but recommended a specialist.

Just spoke to him and a few hundred quid

Part of the issue is that with an engine fault present the regeneration may not happen, so that needs fixed BEFORE doing any DPF work.

After that, I'd be looking to try a DPF clean rather than replacement.

Hvae a look at "o'rileys autos" on youtube to see the process used - essentially, take off one of the pressure sensor tubes, spray a litre or two of cleaning fluid in, and run it.

If you're into DIY, there are similar things available, or Wynns do an off-car chemical to soak it in. I'm about to try Mannol 9694, which is an aerosol version of the spray-into-dpf stuff that commercial places use. Anything that goes into the fuel or the air intake is likely a waste of time.


Glowplug top tip - change them with the engine hot.
