    Hey everyone, So my 330d has developed an issue and I'm at a loss as to what to try next. Basically, it accelerates fine up through the revs/gears (if a little sluggish than it used to be) But if you are in any gear and rev it up to 3000 odd and then let it drop down to about 2400 without...

    Hello everyone, I have a 2004 320d touring and I'm getting a ticking kind of noise from the engine when accelerating in first and second gears, perhaps even third but if there is ticking it's nearly inaudible. This only happens at around 2000 rpm to around 3000 rpm. Additionally my car seems to...

    Any thoughts about this... my 330Ci is not smooth at all off the line. A very small touch on the accelerator results in quite a sharp rise in revs from idle. This makes taking off a bit unrefined (for want of a better word). In connection with other things I've replaced all the rubber pipes...

    Hi guys, Ive got a 2008 520d msport 177bhp (150k mile) m47 engine and i've been having problems with the car being underpowered at low revs. The car accelerates sluggishly up until 2k rpm but it seems the turbo doesnt fully kick in until 2.5k rpm If you drive the car hard it seems drives well...

    Hi all. Had this symptom since I've had the car for a few months. When accelerating, say out of a junction - the car hesitates before moving off. It's annoying, and on occasions has bordered on dangerous! Another example, at the lights give it almost full power -it hesitates, probably a second...

    Hi all, Having some incredibly frustrating issues with my 335d ran fine for about 15,000 miles until one day it cuts out as I’m accelerating, no warning lights no bonging from the dash. Tried starting and just turns over. Took the key out and put it back in and fired right up. Drove another 150...

    Hi My 2009 E91 318i has been making a louder than usual engine note, similar to a blowing exhaust, under acceleration. It also seems to be missing a cylinder when its experiencing this change in engine sound. But once the revs climb, the cylinder seems to kick back to life and power returns...

    Hello All, I have recently noticed my 330D auto is smoking on hard acceleration. A friend followed me at the weekend and confirmed it was grey/blue. Not white and not black. It is not clouds of it, but it is smoking. It is well maintained and it does NOT smoke at idle etc nor visibly in normal...

    Greetings! Ever since I have owned my 320d (coupe facelift 150hp) it has had a very annoying intermitent fault of loosing boost/power. It's remedied very easily by switching the car off for a few seconds then re starting, which cures it for a while. There is no eml or any other warning lights...

    After fixing my obc button I took the car for a spin round the block to check all working OK with steering wheel, indicators etc but kept windows down and either noticed a new noise or existing noise I had not heard yet, windows up and you can't here it, As you accelerate there is a slight whine...

    Hi My 530d auto cuts out during hard acceleration but will restart immediately if you slip it into neutral whilst still moving -can be a bit scary when there is no hard shoulder on the motorway! I have replaced inline fuel pump and leak off test was ok' Error codes on diagnostic test were...

    Hi, i bought this car about 2 weeks ago now but have hardly driven it at speed. Now that I have I think I have noticed a problem with acceleration. When you pull away from say 50mph the acceleration feels lumpy almost like a misfire on a petrol engine, once at speed it holds it fine with no...

    Hi all I have a 2016 320 d efficient dynamics auto, my problem is that when I use kick down or accelerate hard there is about half a second before the car responds, otherwise it's a great car, I was looking for other people's experience of this model and is this just a charictiristic of the...
