Thanks. 500 Euros is a great price, so I'd say refurbished.

As it's electrical I'd guess at battery voltage, something unplugged or an earthing point not connected or bad connection when re-assembling. ______________________________

Well after a long search it was a stuck LH turbo actuator. Bank B is the Left Hand Side seen from drivers view.

I tried very hard to get the turbo actuator running smooth again but with "WD40" its not really working..

Anyone got an idea how to get it running smooth ? Any experiences made with this problem?


I really don't want to replace the LHD Turbo a second time.. This job is just horrible

Probably soot in the vanes so need to be cleaned internally.Sure you will get some product that you can put through to loosen it up?
Good luck. 2012 TDV8 Vogue SE 4.4

A few questions.

Could the actuator be moved before installed? The Vanes and actuator shouldn't be sooted if fully reconditioned with a new CHRA or core.

Was the fan spinning freely before install?
The bearings should be lubed before starting for the first time.

Do you have a IID Tool? It would be good to read boost pressure for each bank.

There are a few possibilities.

1. I'm thinking it's unlikely that the vanes/actuator are stuck solid before install. But possible if supplier is not particularly ethical ie sent you junk.

2. The fan is not generating enough boost to result in the actuator to moving (ECU identifying insufficient boost) because fan is not spinning freely or out of balance (eg cheap knock off CHRA). Need to check boost pressure.

3. The actuator is not plugged in properly, defective or some problem accurately reading boost on that bank. Need to check boost pressure. I'm assuming it's a reconditioned unit and the electronic actuator was not replaced and is up to 10-11 years old. It's also possible but unlikely the turbo actuator needs calibrating like other electrics on the L322. Ive never heard of this though.

Good luck. ______________________________

On the 3.6 tdv8 yes. Not sure about other models. ______________________________

-> yes of cours.

The bearings should be lubed before starting for the first time.

-> was done so this shouldn't be the problem. There was also filled Oil in the Oil access.

Do you have a IID Tool? It would be good to read boost pressure for each bank.

->Unfortunately not, but i have access to a Tester (Bosch KTS) so i can read it..

There are a few possibilities.

1. I'm thinking it's unlikely that the vanes/actuator are stuck solid before install. But possible if supplier is not particularly ethical ie sent you junk.

-> I hope not, but its always the same problem. My actuator rod get always gets stuck in open position and doesn't move back again and i have to free it again. Then the car starts and run smooth till i got it's temperature.... "Kloing Kloing" and the game starts again..

2. The fan is not generating enough boost to result in the actuator to moving (ECU identifying insufficient boost) because fan is not spinning freely or out of balance (eg cheap knock off CHRA). Need to check boost pressure.

-> To be honest i don't understand this question. But the car got enough power and runs very good. I will check Boost Pressure asap. The Actuator is not running very smooth, very rough especially when the car gets warm. I will try to free it with some Teflon Spray the next days and will tell you what happens..

3. The actuator is not plugged in properly, defective or some problem accurately reading boost on that bank. Need to check boost pressure.

It's also possible but unlikely the turbo actuator needs calibrating like other electrics on the L322. Ive never heard of this though.

-> The Turbo Actuator is not needed to be calibrated due to my LR Service. -> I think the best is to read the turbo pressure. You think my MAP sensor could be faulty as well?

Thank you much ahead

As i said the work is nearly done i was a bit too quick..

Now we have the Problem of 2 trouble codes.The Turbo actuators are working -> checked with Camera...

P132E "Turbo boost control B performance"
P138F "Turbo boost control unit Sensor minimum"

Anyone got an idea?

Hi,
yes actually the control arm was stuck and tightened too strong by the company who refurbished the turbos..

I built myself a nice tool which i could attach directly to the control arm and move it free.. Did this movement 100times and went afterwards directly straight to the Autobahn. Since that i never had the same issues again  Current:
