EGR Insufficent Flow - Carista

[Lee540]

2018 150 Manual.

Been hearing a hissing noise under load for the past couple of weeks. After a 300 mile journey through the night, EML popped up and Carista says "exhaust gas insufficient flow A"

My specialist says, either new EGR or blank off EGR.. likely going to be expensive.

I had the inlet manifold replaced earlier in the year due to excessive carbon build up.

No cheap fixes?

A replacement EGR valve is due about 70,000 miles or five years.

It cost about £600 pounds for the part and about four hours labour to change.

So normally about £1000 pound at the garage.

That should get you another 70,000 miles of happy driving.

You probably have a split bellows on one of the EGR pipes, common issue, part has been superceded.
Have a Search with ‘EGR pipe’

Front & rear pipe.

Normally with a heavy exhaust fumes smell.

Front & rear pipe.

Normally with a heavy exhaust fumes smell.

No noticable fumes in the cabin but my nose isn't very good.

Had the engine running now and got my hand right behind the engine, the rear pipe has completely split in half all the way around!

Make sure you get the superceded part not the original as fitted.

Correct part ordered. I need to drive 300 miles tomorrow with the split pipe, then park up till Saturday when new part arrives. Looks like I can swap it out myself easily enough

EGR replaced a few days ago. £878.24. The EGR Cooler and the EGR Valve/pump come as one unit. The full unit was replaced. at 50,000 mls, treated it as a consumable item. As mentioned earlier, another 50K mls of no EGR issues (hopefully). The insufficient flow error came up a few weeks ago. cleared with CArista, and did not come back. May have gone on for another few thousand miles, but as the van is a keeper, did not want it causing any more related issues.

edit: the egr pipe cracked and was replaced on a service a year or two ago.

Will do the cracked pipe now and drop it into my specialist when he is back. If it needs a new unit, will just do it.

Is it such a consumable on the 150 engine? Read about it loads on the 180/204.

Yes, I’ve cleaned a 102 unit, cooler rammed solid with carbon and valve seized, same as 150ps
180ps EGR is a different problem again - internal corrosion.
204ps EGR seems to be a trend for coolant leakage.

New pipe fitted this afternoon, nice and easy on the 150 manual, about 10 mins with good access.

Cleared the fault code and hasn't come back. I will consider won't be long before EGR is totally sooted up like my inlet manifold was and explore my options to either blank and map out or replace.

Awesome.
