W212 E350cdi
So after just spending over a thousand pounds getting the glowplugs replaced on my w212 E350 cdi (2010 128k miles) something unrelatedly weird happened yesterday.
I started the car from cold and put it into drive and went to pull away and the revs rose but I didn't move! despite the dash saying D I was not in drive
So i then tried reverse and it was the same. So I turned the car off then back on and it selected gear normally.
It was find the rest of the day but again earlier today i selected D to start off and nothing. Then I tried R and it selected. Then D and it selected.
what could cause this kind of oddness? the gearbox is very smooth in operation normally and changes gear beautifully
 
Welcome to the forum :thumb:

The first port of call would be to take it to someone, preferably a good independent, with STAR* and get all the fault codes read and more importantly, correctly interpreted. While it's there get them to check the transmission fluid level. It doesn't have to be that low for all sorts of weird things to happen.

*MB's own very expensive and comprehensive diagnostic and servicing system.

£1000 to have glow plugs replaced? 😬😬 are they made of solid gold or something? And regarding gearbox you need to check for fault codes....

well the relay was £240 on it's own and 3 of the plugs were seized and broke getting them out and was charged £150 each (so £450) to get them out by a local specialist

Wow thats mad, I've replaced loads of them and touch wood not 1 snapped 😳

My regular garage tried and couldn't get them to budge and didn't want to risk breaking them. They had been in there for 13 years and 128k miles I guess and one was a little rusty too. Apparently the risk is bits falling into the engine requiring the head off to sort
 
Agree with Stratman. Get the codes read using MB STAR diagnostics before throwing money at it.
It could be electro plate, expensive£££ or just low in oil.
When was the last time the gear box was serviced?

I have owned the car for a little under a year but I have a receipt for the torque converter being removed and repaired with oil,, filter and gaskets from just over 2 years/22k miles ago

The difference is that you know what you are doing. I bet you do them with the engine hot and you take care working them backwards and forwards - taking your time. Of course a hamfisted mechanic will just swing on a ratchet handle, push push push goddang snap. There goes another one.......ker ching more ££££££
 
The fact that the problem goes away with a restart would suggest an electrical problem rather than fluid level. Low fluid level can lead to a delayed take up in drive but it would have to lost a huge amount to cause no drive at all - and then how would it suddenly come back to life. Find a good local independent - it will be cheaper in the long run - they probably would not have snapped 3 glowpugs.
