Ya, MattQ replaced the solenoid in December of 2011. I bought the car in June of 2012. So, the new solenoid is just over 2 years old.
I honestly do not think it is the solenoid as it's done less than 20 000km on this car, but we can look into whether they did change it, but Goch and Cooper are a reliable workshop, I doubt they would say they changed a solenoid, charge R5500 and then not do it. That being said, the car isn't throwing any codes, but for some reason, the car has lost low down torque.
Beisan systems states that Vanos seal issues are Overall loss of torque and power, particularly in the lower RPM range, < 3k. Bogging then surging at 3k RPM. Uneven power distribution and RPM transition. Engine hesitations in the lower RPM range,
This is the exact problem I am having, but the weird thing is, I never had this issue before. I did at one stage have a loss of power at Top end due to exhaust cam being over retarded by Gtech. Peter fixed this issue for me last year, but now I am having the Vanos seals problem, and we just did Vanos seals.
I'm stumped. Possibility of Beisan sending defect seals or wrong seals for this Vanos?

From my understand Nikhil, a faulty plug would throw a code. In fact, Beisan says any failure to do with the solenoid, be it intermittent or no signal to the DME, thus a failed or loose plug, would throw a code and an engine light. I am getting no codes relating to solenoid and no engine light.

I Say pull out all the plugs and have a look as you never know, this is Jezebel and the normal does not apply :rollsmile: , I had a faulty plug on my E36 which never threw any errors or any check engine lights, Which caused a loss of power in the lower rpm band but not present higher up. :flyfun:

We pulled the solenoid on Saturday. Opened the valve cover, checked the Cams as well as the exhaust hub tabs. All is in order.
So not sure...
Going to go Dyno again tomorrow to see if any changes in the graph have appeared.

highly doubt its faulty seals no one else has reported this to me...
Peter has organised to swap out a solenoid pack onto your car to start the process of elimination if the car behaves the same then we know it is not that... if it is the solenoids then its normaly the solder joins... they can be resoldered

LOL. You want to come for a spin?
So, drove her for a bit today, too much traffic to really get her going, but I did some 2500rpm and 3000rpm pulls and she felt strong. So, hopefully whatever Peter did on Saturday, fixed it. Will go Dyno again maybe tomorrow and pull codes and report back.

Highly unlikely to be seals as they are checked before placement and once fitted they are rechecked for correct seating.
Until we fit Philips unit and get a result everything is speculation so I will leave it at that for the time being and worry about it once Philip's unit has been tried.

was hoping to Diagnose Crashes handling problem but... I forgot JHB has no corners :fencelook:

this also points to an electrical problem... with the engine being out so many times and differnt workshops there are probably a few lurking
let hope this one is easy to find

Lol. We are still looking for Control Arms, not just any no name brand, but the proper M control arms.
what does BMW want for the arms?

Everyone but me,lol...just being jealous
Hope you guys found the problem and shes in tip top shape again.
After all the work you guys have done this car will basically be new. Might as well just reset the odometer to 0 and get 'n new service booklet too.

I think what Peter is getting at is the car is most definitely not handed out for Joy rides...
even Alex has not driven it because he has had no reason to that says alot
If Crash wants to let people drive the car then its his choice but this is up to him as the owner not us :rollsmile:

Peter, just give me a call and let me know when you need the car... Anything for our resident spanner wielding Adonis. :rollsmile:
Seriously though.. Crash, was there an improvement when resetting adaptations? Could it not just be a bad batch of fuel causing knocking and bad timing pull?
Bear in mind that you've got extra displacement from the overbore - run bad fuel on a leanish mixture with cam advance in the bottom, and it could be plausible... Try filling up the tank and resetting adaptations before dynoing?
If the issue persists, log the car... Somewhere fueling, timing or cam phasing will deviate from the requested values, pointing to a culprit.
