Hey there,
I have had my 06 ML320 CDI for about 2-3 years now and for the past 4-5 months, it has started showing some signs of old age (105,000 miles).
1. First of all, the engine start up. Every morning it takes quite some time to get the it started, varying between 5-10 and sometimes even 15 seconds. Once started, it's fine throughout the day. If I leave the car off for a few days, it get slightly worse, starting even harder.
My mechanic told me that it might be related to the fact that not all the injectors are working properly. However, lately, I have started to lose trust in my mechanic (had the turbo reconditioned about 1 year ago and last time I took the car to service, he charged another £200 or so on some more turbo work, telling me that it was not working properly....hmmm).
Back to the problem at hand, I started asking around, and was told that the start-up problem might not have anything to do with the injectors, (as the ones that are working fine, should compensate for the ones that are not) and in fact be that the fuel system is losing pressure somewhere. I sense that the latter opinion is much less costly.
2. Secondly, after starting the car, leaving it on idle for 5-10 minutes it start spewing smoke out of the exhaust. Throttling does not help, the smoke keeps coming, even during driving.
Again, asking the mechanic's opinion, he told me that this could also be related to the injectors. For the same reason mentioned above, I started asking some friends about it and found out that (as before) it might not have anything to do with the injectors, but with the EGR valve not being cleaned.
I would very much appreciate some of your opinions on these 2 matters.
I am actively searching for a better mechanic that will not dry my wallet (in London).
PS: one other thing, not related to engine issues though, is that the parking brake handle now sticks out. I can pull the brake, but I need to push the handle back into place. Is there a way to tighten the brake cable to keep the handle back in place?
