W211 E320 CDI jerking excelerating hard in 2nd gear 722.9 7g Tronic

Update on my intermittent kangarooing/jerking: Well Mercedes said i could not get the actuator on its own so needed to buy a whole turbo for £1500. Went to my indie who said he Kew a place who could recondition it for £350+VAT. I was not convinced coz after some research I found out how to take the actuator off the turbo which I did and found a place in Leicester that recondition these for £79.99...I thought it sounded too good to be true so I took a gamble as their EBay reviews looked very impressive. Very fast turn around got the actuator back within 24hrs and plugged it back onto the car(20mins ish) and wow what a difference. Car pulls with more power now and even managed 45mpg which is never got before. I highly recommend these guys to anyone with such fault..it's not always the turbo as the dealer would suggest and for £79.99 surely it's worth a punt

A fix for £80 means as a fix there is likely to be no replacement parts used and is very much likely to be a 1/2 hour to an hour manual task to rectify. Bearing in mind the postage also. The one question I have is - is the unit you posted exactly the same unit you've had returned? Then the question is for £80 is it worth getting your hands dirty yourself to fix or leave it to those who've seen this issue and rectified it numerous times. So most likely a common manufacturing problem, much like the other problems we see with these cars and others do with other makes. When I get the issue on mine I'll certainly try and investigate if a repair is possible within my capabilities, if not then I know where to go.

The top black cover with written Garrett on it was the same but the Silver metal bottom bit was a new part as it was really clean and the number markings that were on my old one where not on the new one coz I took detailed pictures of the Actuator before I posted it as I was a bit sceptical. So far Iv done 1000miles since I got it remanufactured with no issues at all. It also comes with a 2yr warranty so I can complain. You could be right that it's probably just a 30min max repair job

Hi guys can you advise if this is what we are talking about? Also Gareth you say u wd40 the rod I cannot see any rod can you advise - mine jerk the odd time but only in C setting on box nd it has never went into limp mode so don't know if mine at a really early stage?

That's what there on about. I've put white grease on mine but it was very free before hand.

Would white grease not attract dirt and dust? Causing it to seize? When u say it was very free before hand how are u gauging that did u remove top pivot and push and pull rod?

It moves freely on the pivot points as you can twist it. I didn't remove the rod. If it's sticking then that would be crud in the vanes at a guess. Wouldn't think you would get dirt etc on the grease as it's under the engine cover.

Yesterday with the car warm, I had to join a carriageway with some power and kangarooing came in at 2500 revs, scanned for codes this morning and I've a pending P0244 code, car went into limp and had to pull over stop and start to get normal drive back. Fine for the next 1:30 of motorway driving and all good this morning. Will search this forum for more detail on this as I'd lubricated the turbo actuator rods following the last occurrence.

Cheers
