Hi Guys!
I have a new problem!

I've a B Vectra 2.0 DTI and change the transistor 2 months ago (irlr2905).
The car again dont working, but the transistor is good.
What could be the problem?

Hello.

I have the mistake (DTC P1268) with my AUDI A6 2,5 TDI.
If is the amount plate.
Is the transistor defective?

solder the IRL3803s and the car will not start, P1664 and P1564 fault.

I reviewed the welds and seem right, any ideas?

Is it any program or idea, how can I erase the calibration values from the eeprom? It gets full after 3 times recalibration.

Good day members of DK

Hoping that some of the members might be able to help me on this one as I work mostly on VAG so dont know Isuzu well. A friend of mine towed his Isuzu 1 ton pick-up into my shop. He was driving and it just cut out.

It is around a 2004 model 3lt turbo diesel and the diesel pump looks like it could be a VP44. Vin number is : ADMTER77D5C312975.

I have heard that these pumps have the immo box in top of the pump. I have check and it does have a black box on the pump.

I have scanned the vehicle and get the following fault codes which I have attached below for you to take a look at.

I have checked the crank sensor and it is not faulty but now everything is pointing to the immo box on the diesel pump. I have seen the repir method for the VP 44 pumps but also see that there are different vp44 pump models which require different kinds of repairs. Can any of the members maybe identify what vp44 pump this is and direct me to the repair method for this pump immo box?

Many thanks in advance

Hello!

How can i reed the eeprom from the vp44 pump ecu?
THX!

I have non starter Astra G X20DTL with fault code P1345. Does this mean dead transistor (was changed about 5 years ago or so claims the owner), or dead sensor/pump? The car has 410.000km.
