BMW - THE ANNOYING HESITATION AND HOW TO FIX IT

You are ambling along in your lovely BMW and suddenly a gap open up and you want to accelerate to get into it - but all it does is groan and accelerates like a 116i pulling a trailer. Well, this is extremely annoying and has been the case since the 1990's!

This video explains why your BMW hesitates before accelerating - but much more importantly tells you a simple trick to stop it happening so you can release the full beans whenever you want it. Go on, you know you want to!

Thank-you for this. I always wondered why my E46 330ci was reluctant to initially accelerate hard in Drive and seemed quite happy just cruising along. Then I realised that Sport mode and changing down wakes the car up, and it knows you mean business!

Tim, you are gold! I was hesitant to purchase the 650i due to its age and common problems (which are ludicrously expensive). But your guidance has given me the confidence and knowledge to know the issues to look out for and how to fix. Cheers buddy.

Time for me to search for a mechanic to tag along, before I purchase the car 🙂

Brilliant! I have a manual, so other techniques to make the car understand you mean business, but same concept. You need to communicate with the car to get the car to talk to you and give you the best that it has. This is the antithesis of the appliance/car mentality that is popular these days. 😊

Slow drivers in the fast lane? Must be from the USA. Everyone does that here. And if you pass via slow lane, they get road rage from the ego bruising.

Really appreaciate these videos timm, grew up in my dads 645 when I was 2 or 3 and after selling the old gal and buying a newer 650 in 2010, it passed down to me when i went to uni last year and i hope to make it last forever (no worry she's not being abused)

Great video, ok I got a e39 imola red 530 diesel yes diesel auto for the last 18 years, only problem car gave was I had to replace torque converter due to a slight vibration at 55 or 60 mph when the torque is locked on and you power on, bought a new torque fitted my self with a mate on his lift and problem solved and yes I use ur technique left and up on auto gear stick and pulls like the concord did, and still get over 50 MPG in a 2002 3 litre 6 cylinder. Cats removed and swirl flaps removed, Egr blanked off, K/N filter in air housing and straight pipe from turbo to middle box, remap on rolling road, burns so clean mot pass or Nct pass on emissions every time no issues, again great video

Timm, I see that the under hood insulation on your car looks a bit wonky like mine did. I have a 2005 645CI Cabriolet w/ 75K. I looked into replacing the insulation and found it quite costly especially when there was nothing really wrong with the insulation that I had other than the "tabs" no longer fit within the slots in the hood. I trimmed the tabs and cleaned it all very well and then used a silicone adhesive to re-install it. I am no longer embarrassed to open the hood. It looks so much better. I was thinking that as nice as your car is that this would be a simple solution and your subscribers may enjoy this one afternoon low cost upgrade.
Please keep it up, I cannot tell you how much I appreciate all of your videos. Many thanks from the U.S.!

Tim, you taught me something really significant today. A thousand thanks.

Glad to see the 650i back on the road! looking forward to more posts

Iv always thought that of my e63 but assumed that it was something to do with a sensor or just old age. So now I can stop worrying about it . Kinda all makes sense now that it's been explained. And this bit of advice costs me nothing. Which is unusual for my old car 😀👍Thanks again Timm .

[MingeShagger]

I have been doing this since i got my 550i v8, but i also installed a Sprint Booster, which kinda does the same thing, but on Comfort mode (D), i only use Left Up>Up when i need for it aggressive maneuvers😂. Thanks, Tim, for quality content as usual.

Thanka mate. Bought a bmw 435d grand coupe 2016 NYE just gone. I love it but couldn't figure out the delay. I now know. Thank you very much 👍

[thealex_uk]

Brilliant thanks, just got a 645ci and this is great advice explained in an easy to understand way!

[blademan]

1000% this. Been doing it for years.. As Timm says, it becomes a second nature movement, and it also lets passengers in your car know, that they should brace themselves. 😂 Throwing it into sport mode also puts the pedal into a more direct mode mode with the throttle, or some some would say more sensitive. Experience with an e53 4.8is and e39 M5 (manual). The e38 740 doesn’t have steptronic, so I can only drop it down a gear. I wasn’t aware of the why behind the torque converter lockup, I only knew it worked. 😅

Thanks Tim. Another great vid. I drive my 630i like this to get the best out of it, but mine has a different intermittent hesitation where the engine literally does not fire on any cylinders for a second or so if I press the accelerator anything like quickly. If I lift off before the revs have died off completely and reapply smoothly, no issues. If I don't lift off, the engine will die completely or backfire through the inlet manifold. It only happens once every blue moon (every 3 or 4 weeks) when driving, and using the the method in this video certainly reduces the occurrence. I can force it to happen when not driving by just pressing the accelerator quickly to the floor from idle (once the engine is warmed up). It won't happen if the engine is cold and still on fast idle. I don't know if you remember the accelerator pump on an old school carb? If this pump wasn't squirting fuel down the throat of the carb during fast throttle opening, you would get exactly the same symptom as I'm seeing. No faults ever showing in the ECU. I' plan to remove and check the DISA valves and the VANOS solenoids first as they are easy to do, but both of these should be throwing codes if not working...? Any ideas..?

[jagman]

never knew about this, going to try it in the 840 when i finally get it back after some long awaited work

[AlexRussell-bbmq]

Personally the best way to get rid of the hesitation or drop down as you accelerate hard is to fit an induction kit, the issue is due to air flow as the normal intake restricts it when flooring it too much There is only one I could find for the 650i I imported from America. Yes it £300 but the difference is amazing. It is proven from independent reviews to give an extra 12bhp. The mid range is now so much better. Pull away fast at 30 to 40 and the thing takes off. It's feels like DS or sport but with full gear range and no high revs on slowing to sharp corners like DS or sport which can keep the revs up too much. Best £300 I spent makes the car so much more enjoyable.

❤😂 I want to try this but it's raining 🌧 😊 TY for sharing 💖

[bernardpullon]

Awesome Timm. It's all music to me. I put my 97 540i into sport mode (left) and away she goes. If I was really crawling along behind a truck I'd go left and down for third. You just add detail to the stuff I instinctively know and worked out and that's why I appreciate your videos so much. Didn't know about the torque converter stuff.

[priit]

Just brilliant! Gotta try this now also after I had changed spark plugs, stuck DISA valves, all the possible oils and liquids; and cleaned vanos solenoids and valves. 😀 (tbh all those things needed to be changed anyway long time ago also, but previous owner apparently didn't bother... so not sad about changing them. got rid of rough idle and horrible fuel consumption, but the hesitation was still there...)
