Hi guys
startedmy rr this morning and it felt as if it was running on 4 cylinders for the first few seconds before it started running on all 6. driving to work i could feel a miss at slow sitting in traffic speeds, but once speed picked up it almost disappeared. got to work switched it off, then started again and it was fine. it seems to come and go.
this sounds to me like an injector problem, would i be right in thinking that, or is there something else it could be?
when i lifted the bonnet when i got to work, with the car in park you couls see the engine shaking
04 td6 128,000 miles

Get a couple of bottles of Forte diesel treatment into the tank and let it work through the system

sticky injector solenoid maybe??

injector faults are common in the bmw vehicles fitted with the engine i hear... FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's
Mantec Sump Guard, Rigid Load liner, MY10 BT upgrade.

Defo worth trying a fuel system cleaner.. As 47p2 says, get a doze of stuff through the system.
I always stick a bottle of redex in every few months as a preventative measure. Previously..
Vogue SE TD6
Defender 90 2.4
Defender 110 TD5
Vogue 3.5 EFI

Put a bottle of forte in today,so will see how that goes

Worth checking your glowplugs too. It's getting to the time of year that you notice when they don't work!

It's the fact it comes and goes, was fine going to work today, coming home was a different story, missing badly when parking forward and reverse were juddering like mad

if its an intermittant problem i would check the injector loom, the loom is a very common fault on the td6. the loom goes hard and cracks, shorting to ground with movement.

Update
Was going to get leak test done, but got diagnostic done while it was running rough, no 5 cylinder was being shut down by ecu. Decided to remove all injectors to get them checked and refurb the iffy ones.
3 came out without too much effort, the other 3 were solid, and I mean totally solid, no amount of wd40, coke or oven cleaner would move them. Ended up getting a guy out who does mobile injector removal,covers all of Scotland, TF Automotive
Who removed them without damage, cannot recommend him enough.
When they were removed 3 cylinders were carbon'd up to hell so will need a good clean tomorrow, to see how they look, and may need to get the valve seats recut depending how bad they are
