no problem mate thats why people subscribe otherwise you will lose me and not remember I have probably the biggest playlist on KZread for N52 and all the electronics on the E90 E60 and the N52

old video obviously but got an idea for a short video should you be inclined. Would love to see you do that accelerator test for the ignition coils! Dunno if you come across one with bad coils or if you could even do it with a good car and show us what to look for and what might happen if there's a bad coil(s)

Tried to do some preemptive maintenance on my 80k Z4 E89. Bought some ebay vanos solenoids, fitted. Car didn't run as well as the old ones. So put old ones back in, runs great. They will be ok for emergencies, otherwise don't buy cheap. Go BMW.

I would recommend writing the 7 points down into the video description as well as there is a lot of wind in your phone speaker and your voice get muffled.

What is that pipe/hose that hooks onto the side of the air intake silencer box and runs across the top of the intake boot, then down behind the alternator under the manifold? Can't seem to find any information on it anywhere. Need to replace mine as it has broken. Thank you

No problem mate its a common issue where people ain’t even aware after 7 times that’s when the waterpump takes to much heat and overheats the circuit board it takes a lot of power to power the pump that’s why the less you start it the more reliable it will be

So I have a question I can’t get my vehicle to idle correctly. I replaced the MAF because in brimmerlink I wasn’t getting Any values for the the MAF. Once changed the MAF I cant get the car to stay on it rough idles then stutters and dies. All my O2 sensors are giving weird voltages so I’m guess it’s all my O2 sensor. Question is to you is it the O2 sensor causing my bmw N52 not to want to stay at idle?

Comon failure is also coolant plactic holder hose... it cracks every ~100k, chineese metal replacement works forever...

Hi mate great video, Im getting the smoke from the left side where oil is building up and randomly dripping on the manifold ..BUT i have had the valve cover gasket done a year ago! do you think it could be the valvetronic gasket as the oil leaking is from above the gasket.. ive not pulled the cover off yet. No rough running but i do get shit mpg and lose oil.. about 1 litre every 1k. Thanks in advance

Mine seems to have had that mod too, the intake has two DISA valves, even though apparently that's not the 218bhp spec. Mine tick under hard acceleration, I need to look at them before something bad happens... I also think whoever installed that intake didn't bother flashing the ECU accordingly as only one of them seems to be active at all.

Hi, should we use 5W 40 oil in all N52 engines from 2004 to 2015, with more than 100.000 km? OR SHOULD we use 5W 40 oil in just the 3.0L N52 engines from 2004 to 2015 and that they have more than 100.000km?

Hi I appreciate for your videos. Its super helpful! I’ve got some issues on my 09 e90 328i here in US. The car is on 120k miles and I replaced both O2 sensor before cat and bank1 after cat (replaced 3 out of 4) due to CEL CEL never came back on since then but there is slight vibration at idle so I did Valve cover gasket replaced but re-used valve cover (I did valve tronic motor re-learn) Oil filter housing gasket replaced All six coils and plugs replaced Acc belt and tensioner replaced Cleaned MAF sensor and vanos solenoid (both intake and exhaust) BUT I have very strange issue which it makes irregular vibration and when I stop on signal the RPM drops to 450~500 for 1~2 second and comes back to normal (not always but sometimes). Engine doesn’t feel super smooth compare to my other 09 528i in my home country. Also it had cylinder1 misfire code few days ago so I was actually happy because I though I found reason (assumed injector) but its gone again and never came back (there is no single code for engine). This drives me crazy. I pulled cylinder1,2 spark plugs and both looks really good and clean. Another clue is I hear some constant slow tick under intake manifold but mine doesn’t have disa valve so I suspect purge valve but I don’t know if that relate to rpm dropping issue. I am pretty sure there is something wrong but the car doesn’t give me a code!!! Is this relate to vacuum? Help me please thank you so much

Europe I don’t have many places that ship to us as they won’t do it mate I spoke to quite a few companies regarding this and THERE REPLY was the USA AND CANADA are not allowed quality parts with the quality control stamp your government and commissioner of the car industry requests and buys reject parts that are failures from factory that they can’t send here they send to you guys instead I was trying to find out why and I had the phone put down on me that’s why all parts in the Us fail and in the Uk and Eu none of ours fail for that reason that’s why they won’t let you get parts from Europe you can only get Chinese or dealer parts I usually ship parts to people on KZread to help them I will buy them here and then ship them to them to help them out as I understand how it is there There reply was also that if they provided the us and Canada with quality parts that don’t fail you would all drive around without anything failing and the parts stores would not make any money that’s why they only accept Chinese and reject parts from factory that are not allowed in the uk and Eu
