Red flashing light on dash

[Basilbear56]

Hi, hopefully someone on here can help. I have a 2007 Grand Cherokee 3ltr diesel. We have replaced the Turbo and resonator intercooler (problem diagnosed by Jeep scan) and the engine light & red flashing light went off for about 2 months. The red flashing light came back on and a scan said replace glow plug module.

It and the glow plugs were replaced. All good for 1 week and the red flashing light was back. Swirl pool/port? motor replaced. Scan showed all faults gone and cleared. Now it travels about 1klm does a little splutter, the red light comes on and it blows a bit of black smoke (nothing like when the turbo died).

If we turn it off and let it sit for 5 minutes then start up again it will run all day, running, stopping and staring without a problem. No flashing light, no smoke.

Any ideas before it goes back to the mechanic would be greatly appreciated.

Thanks in anticipation.

Is the turbo a G88 version? This number is on the actuator.

It is the light on the far right of your photo Clarky. Sorry dont know what version the turbo is.

The lightning bolt can be caused by either a faulty swirl motor of a faulty (or wrong) turbo actuator.

Just to prove its not the swirl do the resistor mod.

Hi
If it is not the problems pointed out by clarky then my money is on the EGR valve. This can throw the red light.

Thanks Clarky - the swirl pool motor has been replaced, no help. Will talk to mechanic about the actuator.

Thanks to you too Brit30-06 will get the EGR valve looked at.

Shouldn't these come up with a scan? When he replaced the swirl pool motor he scanned it and it came up clear after. All fault codes were removed and the later scan again after the red light came back but it didnt't show any faults???
