smooth

Hi all, First time post so any advice would be appreciated. I bought a 2013 bmw 330d luxury edition, 70k-ish milage (has the standard 18inch wheels) but the auto gearbox doesn’t really feel smooth (i.e. it feels a little rough/jerky, especially when moving through the gears). It’s quite subtle...

Hi all. I’ve recently checked my smooth running values on my code reader and noticed that cylinder 5 is way out of tolerance. Also noticed the engine has a slight missfire and seems under power at times. Would this be a failing coil or injector. I’d be confident in changing the coil but id...

Good Morning everybody. Last days I had a major failure to my E60 520D 120kW (M47N2) 161000 km mileage about DPF clogged and backpressure too high. While trying to solve the problem I did a bit of maintenance: 1. I've cleaned EGR valve 2. I've cleaned Throttle body 3. I've deeply cleaned DPF...

Hi My car is not smooth in acceleration especially when cold although it is not that bad but noticeable, is this normal and what can it be causing this? I have serviced vehicle, cleaned mass airflow sensor, replaced all 4 ignition coils, replaced spar plugs, used Petrol Fuel Injector Cleaner...

Hi, I have a ‘08 E70 3.0 sd. Some time ago, I felt that the engine was running a little rough on idle speed in the morning for a few seconds and after a test with Ista D i got a smooth running controller error. After testing the values, the cyl 2 was at about 5, over the limit. I replaced the...

Hi Everyone i have a BMW X5 E53 2006 which has recently got a very rough idle i think one or maybe more of the injectors are not working properly. I got a INPA lead off ebay but i cannot get it to install on my laptop but i need to find out ASAP the readings of injectors so can get sorted before...

Can't get to the bottom of this. Has anyone else had this/resolved it? Basically no DTC's, no apparent issues, but on both of my scanners (live data) Cylinders 1,2,3,4 & 6 are all within the 200+/- tolerance and Cylinder 5 is 3500+/- :confused:confused:confused:confused

Hi guys, after some help, showing smooth running controller fault. It's a 330d e46 2003 184bhp m57 engine. Just got INPA software and ran some further tests but I'm new to all this so can make head or tail of the information. Any help would be much appreciated. I'm also showing fault 3505 glow...

Hello. I need a sanity check on this. 184hp motor, smooth running controller fault on cylinder 2 and smokey. EGR replaced with new MAF replaced with new All filters new All injectors identified as dodgy by INPA and Autologic replaced with reconditioned ones. Vacuum pipes seated in correct...

Hi guys, thanks in advance for your hep. I've recently gone from a 320i coupe manual to a 420d automatic. I'm posting here as there's hardly any users on the 4 series sub-forum, and the engine/setup is the same as the 3 series, so the question will apply to any 320d automatic drivers. When I...

Hey guys! The problem i am facing is my bmw when i put it in first gear i have to rev it a bit high to get it moving. Its a juddering sensation and feels like the engine is going to stall. It makes the car horrible to drive . The car feels rough in 2nd gear aswell. I got it checked 6months ago...

Hi, I have just purchased the above vehicle with 32k miles on it. I am running fuel cleaner through it due to the low mileage but it has been serviced on time with oil changes etc. After driving it for a while now I have noticed a very subtle running issue where I can feel it's not 'smooth'...

I know there's plenty of threads on shocks, but just wanted a bit of advice more specific to my setup. I recently picked up my E90 M-sport and was finding the ride a little too hard to bear on our crappy roads, lowered springs and run flat potenzas (225/35/19 on front). Went to get a puncture...

About 10 months ago I bought my BMW E65 735i with 50.000 miles on it. It was in perfect condition and it ran super smooth. A few months later the car started suffering from misfires in the morning about once a week (only once or twice during a cold start). After start-up it immediately ran fine...

Hi I'm struggling with a long standing problem with my E92 320d the revs surge up and down when the car is at idle and is noticeable while driving at a constant speed at low revs. I've had the car on various diagnostics and has never came up with a fault code. I've tried the usual unplugging the...
