W211 E280 CDI Turbo Actuator Broken cog?

Guess I'll find out when I've swapped the Lambda sensor, should be here Monday.

Worst case I guess I'm going to need an EGR. Can't believe how expensive EGR's are

My E320cdi ran for 2 years with no issues because of an O2 sensor , I doubt that’s it .

Have a trawl through this thread , there’s a good bit on taking the egr apart that might be worth trying first

How much have you been quoted by MB?

 

[Uridium]

MB haven't quoted me. Although my car is always serviced by a great local indy (plug for MBAutomotive in Lboro ) I tend to swap easily serviceable parts like these myself.

Cheapest EGR's I've seen were around £170 up to around £400

If anyone has a good recommendation for a fairly priced EGR I'd be grateful

Maybe buy a cheap working second hand one in case it’s not the egr ? If you don’t want to try my suggestions above .
We have the same cars by the way .

Yeah I might grab a used one from eBay for now (after I've replaced the O2 sensor)
I have taken the old EGR apart and all seems ok, I've given it a thorough clean and lube and it works fine for about 10 miles or so and then throws a p0404 error

The error you are getting is the same as I was getting. It suggests that the valve is sticking and not
operating over the expected range.

So Lambda sensor swapped today, I've since covered around 30 miles and its not missed a beat, I was getting EGR issues before after just a couple of miles and the car dropping into limp mode but no faults showing at all yet via ODBII. So fingers crossed it was just bad data from the Lambda causing the EGR issue.
I will be taking the car on a longer run tomorrow anyway so time will tell i guess.
In the meantime I found a cheap EGR on Autodoc for £150 that I've ordered just in case, can always return if I don't need it or quality is dubious.

Thanks to all for the advice, should have joined here years ago but never got around to it, threads on here have helped me countless times.

Couple of Gratuitous shots of my two MB's...the CLK220 Sport is a 2008, the E280 CDI Sport is a 2009 (One of the very last W211's I'm told)

CLK is totally stock (Other than a nice factory looking Chinese Android headunit to add Android Auto)
E280 has been remapped but other than that it's stock save for a Pioneer headunit

C-Class and E-Class styling went downhill for me after these models, planning to hold on to them for some time

(Paint correction done by myself, many many hours mopping the paint) and yes the Alloys need a tidy up on both cars, that's happening soon
