    C320 cdi OM642 sometimes loses boost

    The main thing that worked for me was the boost hose which had cracks in and the replacement actuator from turbovanes. (After this failed almost catastrophically) Feel free to post up here if you find anything else relating to the matter. I have suffered the over boost twice since then, but...

    C320 cdi OM642 sometimes loses boost

    I’ll try anything, and as it’s free there’s nothing to lose. Cheers for the suggestions. I may also try and get some smoke for a Vacuum leak test too.

    C320 cdi OM642 sometimes loses boost

    Well it never came up on a mates reader today so that’s all good. the car did cut out with the below condition on an Italian tube drive home. P0234 - Engine boost condition - limit exceeded it was past the motorway speed limit - so I can’t help thinking there’s still a problem somewhere...

    C320 cdi OM642 sometimes loses boost

    I have a refurbed one on the way as the second hand one was going to take too long to arrive. It should be here by 1300hrs today. I intend to remove check/clean the egr valve and then fit new actuator and clear codes, so fingers crossed once fitted and codes all cleared I’m back to happy...

    C320 cdi OM642 sometimes loses boost

    Thanks @Wighty for the swift response. I did a check of all the fuses and they are all ok. I will do the PCV as a matter of course once this issue is resolved. 1 wire had already been re soldered in the actuator but that along with all other connections looked fine. Im hoping that the...

    C320 cdi OM642 sometimes loses boost

    Ok, so now I have limp mode. Upon investigation the actuator is goosed. No movement when switching engine on. Get to 2000 rpm and the car just kangaroos along the road. there is no G Code on the side of the actuator gearbox, so I have ordered a second hand one to see if that gets me right. If...

    Nonstarter.

    I used this site: https://www.downloadworkshopmanuals.com/index.php/mercedes £9.95 for the C-Class. You get the WIS and EPC access. its approx a 50gb download, and then you need to install VMWare player 15 (free) to run it on a virtual machine. Works fine on my windows PC. If you only...

    C320 cdi OM642 sometimes loses boost

    I'm not pulling it off until I have a replacement for it. It must be the issue, reading other forums its a common issue and it causes all my issues. Others have reported the exact same OBD code I received first time round, although my googling never turned up their threads....odd. I have one...

    C320 cdi OM642 sometimes loses boost

    In the last picture, is that a) a coolant return hose b) look like its not home all the way In the second & third pictures is that the hose from the intercooler? Are these likely to be big jobs as the car is my only daily driver?

    C320 cdi OM642 sometimes loses boost

    Ok, I did the TPS reset procedure and things seem improved. Not sure if it’s 100% right but it’s definitely fine for the commute. Haven’t had any error codes popping up either. if after a week no error codes/issues I may swap the old MAP sensor back in to see if it was that that caused my...
